i have a problem. i am using the BrightIdeasSoftware.TreeListView to create treeview in my windows form and i also take the reference of How to create a MultiColumn treeview like this in C# Winforms app but i am not success to create this. Can you please tell me what i am doing mistake to create the treeview. The complete description is below.
i want to add the dynamic collapsible Panel and into this want to add tree in this.
The data will display into the panel according the collapsible panel header id .
i have a parent id and that can have multiple child.
Status Column will display one image
below is my code that i am using to create the treeview
class Node

public string Name { get; private set; }

I'm trying to create pricelist for hotel. I'm having a list of dates, and list of room types in hotel. That lists can contain random number of elements. That is created dynamically, and here is the code:
private void CreateControls() { var colIndex = 0;
var vrsteSoba = _Presenter.VrstaSobeDto.ToArray();
foreach (var bindingItem in vrsteSoba)
{
var lbl = new Label()
{
Width = LABEL_WIDTH,
Height = LABEL_HEIGHT - 5,
Left = 10,
Top = 30 + colIndex * (EDIT_BOX_HEIGHT + SPACE_BETWEEN_CONTROL),
Text = bindingItem
};
_dataPanel.Controls.Add(lbl);
colIndex++;
}
int a = 1;
foreach (var date in _Presenter.CeneTarifa)
{
int y = 0;
var panel = new Panel
{
Height = PANEL_HEIGHT * (vrsteSoba.Length-4),
Width = EDIT_BOX_WIDTH,
Left = a * (EDIT_BOX_WIDTH + SPACE_BETWEEN_CONTROL + 50),
Top = 5
};
_dataPanel.Controls.Add(panel);
var label = new Label
{
Height = EDIT_BOX_HEIGHT,
Location = new Point(0, 10),
Text = date.Datum,
Margin = new Padding(0)
};
panel.Controls.Add(label);
int index = 0;
foreach (var item in date.VrstaSobeCena)
{
var box = new TextBox();
panel.Controls.Add(box);
box.Height = EDIT_BOX_HEIGHT;
box.Width = EDIT_BOX_WIDTH;
box.Location = new Point(0, 30 + y * (EDIT_BOX_HEIGHT + SPACE_BETWEEN_CONTROL));
box.DataBindings.Add(new Binding(nameof(box.Text), date, date.Cena[index].Cena1));
y++;
index++;
}
++a;
}
_dataPanel.AutoScroll = true;
}`
Here is image of that representation.
Now I'm facing a problem of data binding. I need to bind price, two way, for each text box. And I'm stuck.
I have tried to bind it to property name, but then all boxes get same value. If I try to bind it to value via index, I'm getting error
Cannot bind to the property or column 34 on the DataSource. Parameter name: dataMember
Code below is used to fill model that is used in presenter
` private void FillCenePoTarifi() { var sobeArr = VrstaSobeDto.ToArray();
foreach (var datum in Datumi)
{
var dictionary = new Dictionary<string, decimal>();
var cene = new List<Cena>();
foreach (var item in sobeArr)
{
var tarif = _Tarife.Where(x => x.SifTarife == item).FirstOrDefault();
if (tarif != null)
_SastavTarife = HotelierServerLocal.Default.TarifaViewBlo.GetSastaveTarife(tarif.IdTarife);
//proveriti ovu logiku
var cena = _SastavTarife.Where(x => x.Cena1 != 0).Select(c => c.Cena1).FirstOrDefault();
cene.Add(new Cena { Cena1 = cena.ToString()});
dictionary.Add(item, cena);
}
var model = new CenePoTarifi
{
Datum = datum,
VrstaSobeCena = dictionary,
Cena = cene
};
CeneTarifa.Add(model);
}
}`
Finally here are classes that use as model.
` public class CenePoTarifi{
public Dictionary<string, decimal> VrstaSobeCena { get; set; } = new Dictionary<string, decimal>();
public string Datum { get; set; }
private List<Cena> _Cena;
public List<Cena> Cena
{
get => _Cena;
set
{
_Cena = value;
NotifyPropertyChanged("Cena");
}
}
public class Cena :
{
private string _Cena1;
public string Cena1
{
get => _Cena1;
set
{
_Cena = value;
NotifyPropertyChanged("Cena1");
}
}
}`
Does anyone has any suggestions?
Your question is: How to bind dynamically created text box. Here is one tested way for accomplishing that specific task.
First create some textboxes dynamically:
public MainForm()
{
InitializeComponent();
buttonRandom.Click += (sender, e) => generateRandomList();
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
List<TextBox> tmp = new List<TextBox>();
for (int column = 1; column < tableLayoutPanel.ColumnCount; column++)
{
for (int row = 1; row < tableLayoutPanel.RowCount; row++)
{
TextBox textBox = new TextBox { Anchor = (AnchorStyles)0xF };
tableLayoutPanel.Controls.Add(textBox, column, row);
tmp.Add(textBox);
textBox.KeyDown += onAnyTextBoxKeyDown;
}
}
_textboxes = tmp.ToArray();
// Generate first dataset
generateRandomList();
}
TextBox[] _textboxes = null;
Then, whenever a new random list is generated, clear any old text and databindings from every TextBox before creating a new data binding for it.
public static Random Rando { get; } = new Random(2);
private void generateRandomList()
{
// Clear ALL the data + bindings for ALL the textboxes.
foreach (var textbox in _textboxes)
{
textbox.Clear();
textbox.DataBindings.Clear();
}
// Generate and create new bindings
int count = Rando.Next(1, 79);
for (int i = 0; i < count; i++)
{
var textbox = _textboxes[i];
VrstaSobeCena vrstaSobeCena =
new VrstaSobeCena{ Sobe = (Sobe)tableLayoutPanel.GetRow(textbox) };
textbox.Tag = vrstaSobeCena;
textbox.DataBindings.Add(
new Binding(
nameof(TextBox.Text),
vrstaSobeCena,
nameof(VrstaSobeCena.Cena),
formattingEnabled: true,
dataSourceUpdateMode: DataSourceUpdateMode.OnPropertyChanged,
null,
"F2"
));
// TO DO
// ADD vrstaSobeCena HERE to the Dictionary<string, decimal> VrstaSobeCena
}
}
The classes shown in your code as binding sources may not bind correctly. One issue I noticed is that the property setters are failing to check whether the value has actually changed before firing the notification. Here's an example of doing that correctly. (For testing purposes I'm showing a Minimal Reproducible Sample "mock" version of a class that implements INotifyPropertyChanged.)
enum Sobe { APP4 = 1, APP5, STUDIO, SUP, APP6, STAND, STDNT, COMSTU, LUXSTU, APP4C, APP4L, APP62, APP6L }
class VrstaSobeCena : INotifyPropertyChanged
{
decimal _price = 100 + (50 * (decimal)Rando.NextDouble());
public decimal Cena
{
get => _price;
set
{
if (!Equals(_price, value))
{
_price = value;
OnPropertyChanged();
}
}
}
Sobe _sobe = 0;
public Sobe Sobe
{
get => _sobe;
set
{
if (!Equals(_sobe, value))
{
_sobe = value;
OnPropertyChanged();
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
Finally, one way to test the two-way binding is to intercept the [Enter] key.
private void onAnyTextBoxKeyDown(object sender, KeyEventArgs e)
{
if ((e.KeyCode == Keys.Enter) && (sender is TextBox textbox))
{
e.SuppressKeyPress = e.Handled = true;
VrstaSobeCena vrstaSobeCena = (VrstaSobeCena)textbox.Tag;
string msg = $"Price for {vrstaSobeCena.Sobe} is {vrstaSobeCena.Cena.ToString("F2")}";
BeginInvoke((MethodInvoker)delegate {MessageBox.Show(msg); });
SelectNextControl(textbox, forward: true, tabStopOnly: true, nested: false, wrap: true);
}
}
Create a List for storing the textbox:
List<TextBox> lstTextbox = new List<TextBox>();
Create a class object that stores the values of "Date" and "room type"
public class RoomTypeDate
{
public string RoomType = "";
public string DateRange = "";
}
Immediately after you created the textbox, assigned the RoomTypeDate info to the tag, add it to lstTextbox.
foreach (var item in date.VrstaSobeCena)
{
var box = new TextBox();
panel.Controls.Add(box);
box.Height = EDIT_BOX_HEIGHT;
box.Width = EDIT_BOX_WIDTH;
box.Location = new Point(0, 30 + y * (EDIT_BOX_HEIGHT + SPACE_BETWEEN_CONTROL));
box.DataBindings.Add(new Binding(nameof(box.Text), date, date.Cena[index].Cena1));
// add the box to the list
lstTextbox.Add(box);
// mark the box with RoomType and DateRange
RoomTypeDate rtd = new RoomTypeDate();
rtd.RoomType = "APP4"; // get the room type
rtd.DateRange = "1.6 - 30.6"; // get date range
box.Tag = rtd;
y++;
index++;
}
Now, to get and set the room price:
public void SetRoomPrice(decimal price, string roomType, string dateRange)
{
foreach (var tb in lstTextBox)
{
var rtd = (RoomTypeDate)tb.Tag;
if(rtd.RoomType == roomType && rtd.DateRange == dateRange)
{
tb.Text = price.ToString();
return;
}
}
}
public decimal GetRoomPrice(string roomType, string dateRange)
{
foreach (var tb in lstTextBox)
{
var rtd = (RoomTypeDate)tb.Tag;
if(rtd.RoomType == roomType && rtd.DateRange == dateRange)
{
return Convert.ToDecimal(rt.Text);
}
}
return 0m;
}

I am creating a tab page entirley programatically from a button press in the root page of a tabbed control. At present all the page initialisation takes place in the button click method. After all the instantiation, data capture from file and so on, I finally want to adjust the column widths in the data grid view, so that all the row data appears without having to have horizontal scroll bars. With the help of all your contributors I have managed to get it all working but the last step. Running at full speed it appears the DataGridView is accessed before the data load from the table is complete as it fails with an exception because the count derived from RegistersGrid.ColumnCount (local variable l) is zero. It all works fine if I step through the code. I am assuming that I need to put a Mutex of some form to wait for the transfer to complete, but I can't work out where that is taking place in order to reset the flag! If someone can point me in the right direction or if there is better more structured way to approach this I would deeply appreciate the help :-)
I have included all the code in the method just in case, I am afraid I date back a long way so if this looks like the awkward child of assembler,pascal and c with a little c# thrown in, my apologies....it's my age :-)

You can save your control list into a SortedList.
You can use this sorted list for further processing
I have objects which looks like this:
public class ComponentProperty

public string Unit { get; set; }
public string DependencyType { get; set; }
public object ListType { get; set; }

Problem:
Layout is not correct, there are lots of Banding after assigning DataSource to grid as ComponentProperties Class and Specified Column Size does not take any effect on it.
Previously, i was using datatable as datasource that need to replace with object data source. Is there any settings require to work with object datasources.
I got the some solution from Infragistics fourm, that some what solve the layout problem. As i inspected when i use IList then these settings work correct after setting the MaxBandDepth Property at the form load event.
// Load only upto two descendant bands. So even if the data source has more than 3 level
// deep hierarchy, the UltraGrid will only make use of first two levels and ignore the
// levels deeper than that.
this.ultraGrid1.DisplayLayout.MaxBandDepth = 3;
The problem that was occured was similar as asked in below thread:
First Column of Wingrid Extending too large when datasource is IList
By default, the grid synchronizes the column widths of every band. So
in a case like this where you have a recursive data source, there
are essentially an infinite number of bands and for each band the grid
indents a little bit. This means that the first column gets very big
in order to accommodate the indentation all the way down the
hierarchy. The grid limits you to 100 bands of depth by default,
but that still means 100 level of indentation.
So there are a number of ways you can handle this.
Set MaxBandDepth on the grid to a smaller value. I recommend a value
of between 5 and 8. This will give you pretty good performance on a
decent machine and most users probably won't drill down more than 5
levels, anyway. You could set AllowColSizing to Free. This will stop
the grid from synchronizing the column widths and allow each band's
columns to be sized independently.

I'm trying to bind data with a chart to display it. However when I'm trying to link one of the columns with one of the axis of the chart it comes up with "The name Column1 does not exist in the current context" error. Does anybody know what I'm doing wrong and how to fix it?
Here is my code:
namespace bike
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
var col1 = new List<string>();
var col2 = new List<string>();
var col3 = new List<string>();
var col4 = new List<string>();
var Column1 = col1.Select<string, int>(q => Convert.ToInt32(q));
var Column2 = col2.Select<string, int>(q => Convert.ToInt32(q));
var Column3 = col3.Select<string, int>(q => Convert.ToInt32(q));
var Column4 = col4.Select<string, int>(q => Convert.ToInt32(q));
dataGridView1.Columns.Add("col1", "Heart Rate");
dataGridView1.Columns.Add("col2", "Speed");
dataGridView1.Columns.Add("col3", "Power");
dataGridView1.Columns.Add("col4", "Altitude");

continue;
isInHRData = true;
continue;
}
else if (line.StartsWith("[") && line.EndsWith("["))
break;
string[] columns = line.Split('\t');
if (columns.Length > 0)
col1.Add(columns[0]);
if (columns.Length > 1)
col2.Add(columns[1]);
if (columns.Length > 2)
col3.Add(columns[2]);
if (columns.Length > 3)
col4.Add(columns[3]);
/*col1.Add(columns[0]);
col2.Add(columns[1]);
col3.Add(columns[2]);
col4.Add(columns[3]);
*/
dataGridView1.Rows.Add();
for (int i = 0; i < columns.Length; i++)
{
dataGridView1[i, row].Value = columns[i];
}
row++;
}
int maxSpeed = Column2.Max();
maxSpeed = maxSpeed / 10;
string MaxSpeed = Convert.ToString(maxSpeed);

You're declaring Column1 as a local variable within your (rather long) button1_Click method. If you want it to be part of the state of the object, which will make it available in button2_Click, you should declare it as an instance variable instead.
You might want to consider what will happen if button 2 is clicked before button 1 though.
