How to filter ListView by using a ComboBox?

I have a TextBox that searches whatever I have in my ListView. I would like to have a ComboBox that will allow the user to “Show All”, “Show Match” and “Show Non Match” within the ListView depending on search criteria.
private void SearchBtn_Click(object sender, EventArgs e)
{
int count = 0, searchStartIndex = selectedIndexPos = 0;
// Clear previously selected indices
listView.SelectedIndices.Clear();
string target = searchTextBox.Text;
// Search for item with text from the search text box, including subItems, from searchStartIndex, not a prefixSearch
ListViewItem item = listView.FindItemWithText(target, true, searchStartIndex, false);
/*----------------------------------------------------------------------------------------------------*
* While the search results in an item found continue searching. *
*----------------------------------------------------------------------------------------------------*/
while (item != null)
{
count++;
// Update progressBar
progressBar.Value = (int)((float)searchStartIndex / listView.VirtualListSize * 100);
ListView.SelectedIndexCollection indexes = listView.SelectedIndices;
if (!indexes.Contains(item.Index))
{
listView.SelectedIndices.Add(item.Index);
}
/*----------------------------------------------------------------------------------------------------*
* Set the start index to the index after the last found, if valid start index search for next item.*
*----------------------------------------------------------------------------------------------------*/
if ((searchStartIndex = item.Index + 1) < listView.VirtualListSize)
{
item = listView.FindItemWithText(searchTextBox.Text, true, searchStartIndex, false);
// count++;
}
else
{
item = null;
}
}
if (listView.SelectedIndices.Count == 0)
{
MessageBox.Show("Find item with text \"" + searchTextBox.Text + "\" has no result.");
}
else
{
RefilterListView();
listView.EnsureVisible(listView.SelectedIndices[0]);
}
}
I would like to have my items in the 'ComboBox' to help filter my 'ListView'. The "Show All" should display all contents of 'ListView' along with item that was searched, the "Show Match" should show only the searched item removing everything else that doesn't match the search and "Show Non Match" should show all of the contents from 'ListView' that doesn't match the searched item.

I can't do it exactly in your case. But I hope I realize it. I mean this is just a solution. You can customize it for your case.
First of all, put a BindingSource on your Form and bind it to your data:
bindingSource1.DataSource = data;
Then bind your ListView(actually DataGridView) to the BindingSource:
dataGridView1.DataSource = bindingSource1;
And then define an enum like this:
public enum Something
{
ShowMatch = 1,
ShowNonMatch = 2
}
Now, put a ComboBox on your Form and add your options to it:
comboBox1.Items.Add("Show All");
comboBox1.Items.Add("ShowMatch");
comboBox1.Items.Add("ShowNonMatch");
comboBox1.SelectedIndex = 0;
After that, you can catch the selected item in SelectedIndexChanged:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex == 0)
bindingSource1.Filter = null;
else
bindingSource1.Filter = $"Name = '{comboBox1.SelectedItem.ToString()}'";
}

How to get multiple selected items from ListPicker and display them in MessageBox

Here is my code for the list of the items in a ListPicker. What I am trying to do is select one or more options and then after I press submit button I would like to display a MessageBox with the selected Items separated by commas. I also would like to store this value of the items selected to the database but, the first I am trying to do is populate the data into MessageBox.
lstPickerType.Items.Add("Aircrafts");
lstPickerType.Items.Add("Boats");
lstPickerType.Items.Add("Cars");
lstPickerType.Items.Add("Helicopters");
lstPickerType.Items.Add("Electric Powered");
lstPickerType.Items.Add("Gas Powered");
Here is the code that I have got to create a string from the list that is then displayed when the ListPicker is collapsed.
private void lstPickerType_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
lstPickerType.SummaryForSelectedItemsDelegate = SummarizeItems;
}
private string SummarizeItems(IList items)
{
if (items != null && items.Count > 0)
{
string summarizedString = "";
for (int i = 0; i < items.Count; i++)
{
summarizedString += (string)items[i];
// if the item is not last coma is added
if (i != items.Count - 1)
summarizedString += ", ";
}
return summarizedString;
}
else
return "Nothing selected";
}
Finally for the button to display the MessageBox i have following code.
private void btnAddLocation_Click(object sender, RoutedEventArgs e)
{
foreach (var item in this.lstPickerType.SelectedItems)
{
var items = new List<object>();
MessageBox.Show(items.ToString());
}
I would really appreciate if anyone could help me to solve this issue. Thank You.

I'm a bit rusty of C#, and i don't have visual studio in this pc, but I would achieve your result without the selectionchanged event in the listpicker.
Trythis code in the button click:
Edit: a cast was missing.
private void btnAddLocation_Click(object sender, RoutedEventArgs e)
{
string r = "";
for (int i=0; i<this.lstPickerType.SelectedItems.Count; i++)
{
r += ((ListPickerItem)this.lstPickerType.SelectedItems[i]).Content;
if (i != this.lstPickerType.SelectedItems.Count - 1)
r += ", ";
}
MessageBox.Show(r);
}

Finding specific value within a loop

I'm using an Enum within a ComboBox. I want it to allow editing, so that the user can type things in it. I converted the Enum to a string[] arrayItems while listItems is the length of the Enum list.
Now I want to check the users text input: If it isn't listed, it should show a message that the item is not listed there.
But for my code (below) it shows me a error multiple times:
// Converted enum to string[] before
for (int i = 0; i < listItems; i++)
{
if (comboBox1.Text != arrayItems[i])
{
message = string.Format("Sorry! " + comboBox1.Text + " not found.");
}
}
This shows error every time I start it as it iterates through each and every element in the list. I want that if this could check the whole Enum list and give the error once in case of wrong input.

You can change your loop as
bool ok = false;
for (int i = 0; i < listItems; i++)
{
if (comboBox1.Text == arrayItems[i])
{
ok=true;
break;
}
}
if(ok==false)
{
message = string.Format("Sorry! " + comboBox1.Text + " not found.");
}

if(arrayItrmd.Contains(combobox1.Text))
{
//logic if trur
}

You can use LINQ's All for this. As the name implies, it will only be true if all elements correspond to your query. It's basically the equivalent of !Any
if (arrayItrmd.All(item => item != comboBox1.Text))
{
message = string.Format("Sorry! " + comboBox1.Text + " not found.");
}
This means "If each element from arrayItrmd is not equal to comboBox1's text, assign the message."

You can ignore the use of a loop
if(tmpImageArray.FirstOrDefault(a => a == comboBox1.Text) == default(String))
{
message = comboBox1.Text + " not found";
}
else{
message = comboBox1.Text + " found";
}

I have solved this problem like this,
First my enum that I will bind to my combobox
public enum comboboxVals
{
one, two, three
}
Then set my combobox's datasource like this
comboBox1.DataSource = Enum.GetNames(typeof(comboboxVals));
and then implemented code in one of my combobox events to check if the value is valid like combobox Leave, Validating and Validated events..
private void comboBox1_Validating(object sender, CancelEventArgs e)
{
var cbx = sender as ComboBox;
if (!Enum.IsDefined(typeof(comboboxVals), cbx.Text))
{
MessageBox.Show(cbx.Text + " not in the list");
e.Cancel=true;
}
else
{
// Implement your logic here
}
}

Combobox SelectedItem not working propely

I'm trying to retrieve the selected item from a combobox, though i can't get it to work.
Form1 form = new Form1();
string cpuCount = form.comboBox1.SelectedItem.ToString();
Now, this is not returning anything. BUT, if i insert this code in my InitializeComponent(), it selects item with index = 3, and return that proper item.
comboBox1.SelectedIndex = 3;
Why does it behave like this? If I now select for example item with index = 5, it still will think the selected item is the one with index = 3.
---------- I think i should expand to show you how my code looks.
Form1 - adding all items to the comboboxes.
public partial class Form1 : Form
{
Profile profile = new Profile();
public Form1()
{
InitializeComponent();
Profile profile = new Profile();
string[] prof = profile.getProfiles();
foreach (var item in prof)
{
comboBox5.Items.Add(Path.GetFileNameWithoutExtension(item));
}
int ram = 1024;
for (int i = 0; i < 7; i++)
{
comboBox4.Items.Add(ram + " GB");
ram = ram * 2;
}
int vram = 512;
string size;
for (int i = 0; i < 5; i++)
{
if(vram > 1000)
{
size = " GB";
}
else
{
size = " MB";
}
comboBox2.Items.Add(vram + size);
vram = vram * 2;
}
for (int i = 1; i < 5; i++)
{
comboBox1.Items.Add(i * 2);
}
for (int i = 0; i < 5; i++)
{
comboBox3.Items.Add(i * 2);
}
private void button3_Click(object sender, EventArgs e)
{
string current = profile.currentProfile();
profile.saveProfile(current);
}
}
So, button3 is my "save"button.
And here is my "Profile"-class
class Profile
{
public string folder { get; set; }
public Profile()
{
this.folder = "Profiles";
if (!File.Exists(folder))
{
Directory.CreateDirectory(folder);
File.Create(folder + "/default.cfg").Close();
}
}
public string[] getProfiles()
{
string[] files = Directory.GetFiles(folder);
return files;
}
public void saveProfile(string filename)
{
Form1 form = new Form1();
string cpuCount = "cpuCount=" + form.comboBox1.SelectedItem;
string RAM = "maxRAM=" + form.comboBox4.SelectedItem;
string VRAM = "maxVRAM=" + form.comboBox2.SelectedItem;
string threads = "cpuThreads=" + form.comboBox3.SelectedItem;
string path = folder + "/" + filename;
StreamWriter sw = new StreamWriter(path);
string[] lines = { cpuCount, RAM, VRAM, threads };
foreach (var item in lines)
{
sw.WriteLine(item);
}
sw.Close();
}
public string currentProfile()
{
Form1 form = new Form1();
string selected = form.comboBox5.SelectedValue + ".cfg".ToString();
return selected;
}
}
Thank you.

The problem is that there is nothing selected in your ComboBox. You create your form and then, without previous user interaction, you want to get the SelectedItem which is null at that moment.
When you create ComboBox control and fill it with items, SelectedItem property is null until you either programratically set it (by using for example comboBox1.SelectedIndex = 3) or by user interaction with the control. In this case you are not doing anything of the above and that is why you are geting the mentioned error.
EDIT Based on the edited question
Change your code like this:
first change the saveProfile method so you could pass the four strings which you write into the text file. Note that you could alternatively pass the reference of the form but I wouldn't suggest you that. So change the method like this:
public void saveProfile(string filename, string cpuCount, string RAM , string VRAM , string threads)
{
string path = folder + "/" + filename;
using(StreamWriter sw = new StreamWriter(path))
{
sw.WriteLine("cpuCount=" + cpuCount);
sw.WriteLine("maxRAM=" + RAM );
sw.WriteLine("maxVRAM=" + VRAM );
sw.WriteLine("cpuThreads=" + threads);
}
}
And then call it from button3 Click event handler like this:
private void button3_Click(object sender, EventArgs e)
{
string current = profile.currentProfile();
string cpuCount = this.comboBox1.SelectedItem.ToString();
string RAM = this.comboBox4.SelectedItem.ToString();
string VRAM = this.comboBox2.SelectedItem.ToString();
string threads = this.comboBox3.SelectedItem().ToString();
profile.saveProfile(current, cpuCount, RAM, VRAM, threads);
}
Or alternatively
private void button3_Click(object sender, EventArgs e)
{
string current = profile.currentProfile();
profile.saveProfile(current, this.comboBox1.SelectedItem.ToString(), this.comboBox4.SelectedItem.ToString(), this.comboBox2.SelectedItem.ToString(), this.comboBox3.SelectedItem().ToString());
}

From what I can see, you are calling form.comboBox1.SelectedItem.ToString() right after the creation of Form1. This means that the cpuCount variable is initialized right after the form is created, thus far before you have the chance to change the selected item with your mouse.
If you want to retrieve the value of the combobox after it is changed, you can use the SelectedIndexChanged event.

First of all, add a Form_Load Event and put your code in the handler. (use constructor for property initialization and other variable initialization)
private void Form1_Load(object sender, EventArgs e)
{
this.comboBox1.SelectedItem= 5; // This will set the combo box to index 5
string cpuCount = this.comboBox1.SelectedText; // This will get the text of the selected item
}
so you get the value of item at index 5 in cpuCount variable.
The selected clause gives you the values AFTER you have selected something, by default(when you run your app) there is nothing selected in the comoboBox, hence, it displays the value as null, after selecting the item you can use the combobox's selectedItem, selectedIndex, selectedText and selectedValue properties.
You can also use databinding to display items in the combobox, which in my view is a better way then adding the items manually.
to databind your combobox you can use,
// Bind your combobox to a datasource, datasource can be a from a database table, List, Dataset, etc..
IDictionary<int, string> comboDictionary = new Dictionary<int, string>();
comboDictionary.Add(1, "first");
comboDictionary.Add(2, "second");
comboDictionary.Add(3, "third");
comboBox1.DataSource = comboDictionary;
comboBox1.DisplayMember = "Key";
comboBox1.ValueMember = "Value";
//
And here now you can use combobox1.SelectedIndex to go through the item collection in the datasource :) and it will give you the value against your keys when you use combobox1.SelectedValue. Hope this helps.

Your ComoboBox doesn't have items in it. So it will not return properly. You are accessing combobox selected value rights after making form object.
And if it comboBox has items then nothing is being selected. By default nothing is selected in comboBox. You need to set it. Use this. What it returns? Set comboBox.SelectedIndex and then get selectedItem.
int selectedIndex = form.comboBox1.SelectedIndex;
Try this. Add some items in ComboBox and then get selectedItem.
Form1 form = new Form1();
form.comboBox1.Add("Item 1");
form.comboBox1.Add("Item 2");
form.comboBox1.Add("Item 3");
form.comboBox1.SelectedIndex = 1;
string cpuCount = form.comboBox1.SelectedItem.ToString();

How do I edit the name of an item in a CheckedListBox?

I have a CheckedListBox that has X number of items. These items are placed there at runtime. These items are supposed to represent reports that can be displayed in the DataGridView. What I need to do now is display the record count for each report in parenthesis right next to the report name. I tried, not for too long, to edit the actual name of the item but couldn't find out how to do it. So then, I brute forced it. Saved the items to an array, cleared the items, appended the record counts to each item in the array, created new items. Well, this has caused issues because now it's not retaining my checks and the reason why is because whenever I generate the reports, I clear the items and recreate them. Well, rather than doing another foreach loop to save the checked status, does anyone know of a way to change the text of existing items in a CheckedListBox?
Here is the code I currently have:
In the MainForm.Designer.cs:
this.clbReports.Items.AddRange(new object[] {
"Report 1",
"Report 2",
"Report 3",
"Report 4",
"Report 5",
"Report 6",
"Report 7",
"Report 8",
"Report 9",
"Report 10",
"Report 11"});
And it looks like:
And I want it to look like (but there won't all be 0's):
Here is the SelectedIndexChanged function:
private void clbReports_SelectedIndexChanged(object sender, EventArgs e)
{
string strCheckBox = clbReports.SelectedItem.ToString();
bool bShowAllIsChecked = clbReports.GetItemChecked(clbReports.FindString("Show All Error Reports"));
bool bSelected = clbReports.GetItemChecked(clbReports.FindString(strCheckBox));
int nIndex = -1;
if (strCheckBox.Contains("Show All Error Reports"))
{
foreach (string str in _strReports)
{
if (!str.Contains("Show All Error Reports") && !str.Contains("Show Tagged Records"))
{
nIndex = clbReports.FindString(str);
if (nIndex > -1)
{
clbReports.SetItemChecked(nIndex, bSelected);
}
}
}
}
else
{
if (strCheckBox.Contains("Show All Error Reports") || bShowAllIsChecked)
{
foreach (string str in _strReports)
{
nIndex = clbReports.FindString(str);
if (nIndex > -1)
{
clbReports.SetItemChecked(nIndex, false);
}
}
}
nIndex = clbReports.FindString(strCheckBox);
if (nIndex > -1)
{
clbReports.SetItemChecked(nIndex, bShowAllIsChecked ? true : bSelected);
}
}
string[] strCheckedItems = new string[clbReports.CheckedItems.Count];
clbReports.CheckedItems.CopyTo(strCheckedItems, 0);
List<string> checkBoxReportFilter = new List<string>();
foreach (ReportRecord obj in this._lstReportRecords)
{
foreach (string str in strCheckedItems)
{
if (str.Contains(obj.Description))
{
checkBoxReportFilter.Add(obj.PartID.ToString());
}
}
}
try
{
if (checkBoxReportFilter.Count == 0 && clbReports.CheckedItems.Count > 0)
{
throw new NullReferenceException();
}
_strReportFilter = String.Join(",", checkBoxReportFilter.ToArray());
}
catch (NullReferenceException)
{
_strReportFilter = "-1";
}
generateReport();
}
And here is the code where I am clearing the items, getting the report counts and creating the new items.
_lstReportRecords = _dataController.ReportList;
bool[] bChecked = new bool[clbReports.Items.Count];
int nCounter = 0;
foreach (string str in _strReports)
{
foreach (string str2 in clbReports.SelectedItems)
{
bChecked[nCounter] = str2.Contains(str);
}
nCounter++;
}
clbReports.Items.Clear();
nCounter = 0;
foreach (string str in _strReports)
{
int nCount = _lstReportRecords.Where<ReportRecord>(delegate(ReportRecord rr) {
return rr.Description == str;
}).Count();
string newReport = str + " (" + nCount + ")";
clbReports.Items.Add(newReport);
clbReports.SetItemChecked(nCounter, bChecked[nCounter]);
nCounter++;
}
Please tell me there is an easier way to do this. I tried doing foreach loops through the clbReports.Items but it wants me to cast it to a string (errored on me when trying to cast to a CheckBox) so I couldn't change the value. And even if I could cast it to a CheckBox, I have a feeling it will give me the error that Enumeration has failed because the list has been changed (or however they word it). Any and all help is welcome. Thanks.
Edit: Please know that the Report X are just so that the actual report names aren't displayed to keep it generic. However, in the code, I just copied and pasted so the Show All Error Reports and Show All Tagged Records are reports I need to check.

The right ( == most simple and most direct) answer and solution is:
this.clbReports.Items[nIndex] = "new text of the item"
yes, those items are of type "object". No, nobody minds that, string is an object too ;)

If I were you, I'd try to give the INotifyPropertyChanged Interface a go.
You Shouldn't mess with events unless necessary. this will mean you can't use the designer to create the items, but as far as I've understood, it's a runtime-modified list anyway...
In detail:
• Create A Class (e.g.'Foo') that Implements INotifyPropertyChanged (Basically this will tell any listener that the text property has changed). This class will hold the names of all entries.
• create an ObservableCollection and bind your CheckedListBox to that Collection. In WinForms you will have to create a DataBindingSource and plug your Collection to one end and the ComboBox to the other end.
• Any change made to the collection will be visible in the control.

Sebi

In order to change the items in a ListBox (or a CheckedListBox), you should change these items' ToString() result.
The easiest solution would be to create a "Holder" class, which has a reference to the report it represents. Then the Holder class' ToString() method should be something like this:
public override string ToString()
{
return String.Format("{0} ({1})", BaseStr, MyReport.RecordCount);
}
If you change MyReport.RecordCount somehow (because a report's record count changes), you can just call clbReports.Refresh(), and it'll automatically show the new value.
I think this way you don't even need the temporary array solution in the second code block; however, I'd like to suggest an alternative way of getting the item's checked state.
You can iterate through the clbReports.CheckedIndices, and fill your bChecked array with true values only for indices in that array.

Well, due to time constraints I tried something else. I went with a ListView where CheckBoxes = true and View = List. I also removed Show All Error Reports and Show Tagged Records to checkboxes outside of the list. This made it a lot easier to do the functions I wanted. Here is the new code.
MainForm.Designer.cs
//

this.cbAllErrorReports.Location = new System.Drawing.Point(6, 9);
this.cbAllErrorReports.Name = "cbAllErrorReports";
this.cbAllErrorReports.Size = new System.Drawing.Size(102, 17);
this.cbAllErrorReports.TabIndex = 2;
this.cbAllErrorReports.Text = "All Error Reports";
this.cbAllErrorReports.UseVisualStyleBackColor = true;
this.cbAllErrorReports.CheckedChanged += new System.EventHandler(this.ShowAllErrorReports_CheckChanged);

Code to add counts to CheckBoxes

foreach (ListViewItem lvi in listView1.Items)

int nCount = _lstReportRecords.Where(rr => lvi.Text.Contains(rr.Description)).Count();
nTotalCount += nCount;
lvi.Text = (lvi.Text.Contains("(") ? lvi.Text.Substring(0, lvi.Text.IndexOf("(") + 1) : lvi.Text + " (") + nCount.ToString() + ")";
}
cbAllErrorReports.Text = (cbAllErrorReports.Text.Contains("(") ? cbAllErrorReports.Text.Substring(0, cbAllErrorReports.Text.IndexOf("(") + 1) : cbAllErrorReports.Text + " (") + nTotalCount.ToString() + ")";
int nTaggedCount = _lstReportRecords.Where(rr => rr.Description.Contains("Tagged")).Count();
cbTaggedRecords.Text = (cbTaggedRecords.Text.Contains("(") ? cbTaggedRecords.Text.Substring(0, cbTaggedRecords.Text.IndexOf("(") + 1) : cbTaggedRecords.Text + " (") + nTaggedCount.ToString() + ")";
Thank you all for your help and ideas.
