I have a List<> of items which are stored in a ListView with CheckBox'es. What I need is to store checked items to another List<>. Here is the code how the ListView is displayed and populated with data:
List<Product> _productsList = ProductsFromXml();
List<Product> checkedProducts = new List<Product>();
productsListView = FindViewById<ListView>(Resource.Id.listView1);
productsListView.Adapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItemMultipleChoice, _productsList);
productsListView.ChoiceMode = ChoiceMode.Multiple;
Ok. Below is the c# code:
foreach (ListViewItem xitem in productsListView.CheckedItems)
{
// Do whatever you want with checked item 'xitem'
}

Hi all i have a list string like
List<string> numbers=new List<string>();
now i want to convert it on observable collection i have converted it successfully like
ObservableCollection<string> myCollection = new ObservableCollection<string>(numbers);
but when i am deleting a item from list box like
myCollection.Remove(listBox1.SelectedItem.ToString());
listBox1.ItemsSource = myCollection;
the above code is deleted all the item in list box but i want to delete specific item in list box.
Try this
Initialize collection and lsitbox
List<string> numbers=new List<string>();
//numbers.Add("test"); //populate list
ObservableCollection<string> myCollection = new ObservableCollection<string>(numbers);
listBox1.ItemsSource = myCollection;
now use the below code to remove the selected item from the list
var selectedItem =listbox1.SelectedItem as string;
if(myCollection.Contains(selectedItem)
{
myCollection.Remove(selectedItem);
}
Instead of binding ObservableCollection you can directly bind List<string> to your listBox1.ItemsSource. See this example to bind List<string>
windows phone data binding listpicker to List of Strings
To remove items from list try this
listBox1.Items.Remove(listBox1.SelectedItem);
Answer_:
numbers.RemoveAt(listBox1.SelectedIndex);
listBox1.ItemsSource = null;
listBox1.ItemsSource = numbers;
How to add ListView selected items in other ListView?
Example project:
ExpTreeLib
Put this form ListView2 and add lv.selectedItems.
Thanks in advance.
You can use this method to add the items
ListView list = new ListView();
ListViewItem item = new ListViewItem();
// add them
list.Items.Add(item);
This would be enough, now you can use a simple loop for each element to add it to that list.
foreach (ListViewItem item in ListView.SelectedItems) {
// create a new list, or use currently present list
// add each item to it using .Add() method.
}
I'm trying to get listView items into an array..
in listBox
listBox1.SelectedItems
would do the trick.
But it didn't work in listView...
any Ideas???
Do like this,
var myList = new List<string>();
foreach(ListViewItem Item in ListView.SelectedItems)
{
myList.add(Item.Text.ToString());
}
var myArray = myList.ToArray();
I got 3 List (L1,L2,L3) and i want to show them on ListView.But i cant add or convert, List data's to ListViewItem.Something like this
List<string> for96 = new List<string>();
List<string> for97 = new List<string>();
List<string> for98 = new List<string>();
ListView lv1=new ListView();
ListViewItem lvitem = new ListViewItem();
lvitem.Text=for96;
lvitem.items.add(97);
lvitem.items.add(98);
lv1.items.add(lvitem);
You could take a variety of routes with this, but here's one possibility.
Join the three lists of strings together and then set that as the data source for your ListView:
var combinedLists = for96.Union(for97).Union(for98).ToList();
listView.ItemsSource = combinedLists;
I'm working in a webpart. I filter (with caml) a SharePoint list and put my results in a List<SPListItem>.
Now, i need to populate another SharePoint List (I created that list in the same code) and i can't find the way to do that.
List<SPListItem> results = new List<SPListItem>() //results have the result of my query
.
.
.
SPList listFiltered = mySite.Lists[newListName]; //listFiltered is my newlist
SPListItemCollection newListItems = listFiltered.Items; //newListItem are the item from my list
foreach (SPListItem item in results)
{
//I don't know how to send my result to my SharePoint list :(
}
You will need to define your other List, then you can add a new SPListItem to that list with the columns that list contains. I am not sure what results is, if that is a typo or not, but I included that in my answer. You would need to change that if results does not exist.
SPList secondList = web.Lists["MyList"];
foreach(SPListItem item in results)
{
SPListItem Item = secondList.Items.Add();
item["Title"] = companyName
item["DateReceived"] = System.DateTime.Now;
item["Description"] = companyDesc;
item.Update();
}
