Winforms, databinding, Listbox and textbox
- by Snake
Hi dear friends,
I have a ListBox (MyListBox) on my screen, and a Textbox (MyTextBox).
The ListBox is filled with a List(Of T), which are all custom items.
Now I try to do this:
The ListBox' datasource is the List(Of T).
Now when an Item changes I want the textbox to be updated to a particular property of the selected item in my ListBox.
In code this means:
Me.MyListBox.DisplayMember = "SelectionName"
Me.MyListBox.ValueMember = "Id"
MyTextbox.DataBindings.Add(New Binding("Text", Me._listOfItems, "SelectedItem.Comment", True, DataSourceUpdateMode.OnPropertyChanged))
Me.MyListBox.DataSource = Me._listOfItems
this does not work. But when I bind to SelectedValue instead of SelectedItem it works perfectly.
The _listOfItems is declared as this:
Dim _listOfItems As List(Of MyItem) = New List(Of MyItem)()
Where MyItem is this:
public class MyItem
{
public string SelectionName { get; set; }
public int Id { get; set; }
public string Comment { get; set; }
}
I tried overriding the ToString() in MyItem so that it would use that. But that doesn't work either.
Anybody care to give it a try?
Thanks!
