Getting the String Text of SelectedItem in Silverlight Listbox (C#)

Question

I have a listbox in a Silverlight C# app which is binded to some data from a database in XAML:

<StackPanel>
      <TextBlock x:Name="ItemText" Text="{Binding Name}" Foreground="White" FontSize="35" TextAlignment="Left"/>
      <TextBlock x:Name="DetailsText" Text="{Binding Description}" Foreground="Gray" Margin="0,-6,0,3" />
</StackPanel>

Now in code behind file, i am trying to get the string "Name" (binded above) based on the selection user makes in the listbox.

I tried the SelectedIndex property of listbox but it only returns integer. Can anyone help me?

Answer 1

Try to use the SelectedItem property instead

Edit: Or even better bind the SelectedItem property to a value in your ViewModel if you use the MVVM pattern in your application.

Answer 2

I think , ListBox's ItemSource poperty is binded to some custom collection of objects

1- if you handeling selectionchanged event than you can use SelectedItem property

that means

CustomObject obj = lstName.SelectedItem as CustomObject


if(obj!=null)

{
   string name = obj.Name;
}

where lstName is name of your listbox

and CustomObject is the type of object in the ItemSource property of listbox

Have you tried using , SelectedItem property and if it is not null then try to find the TextBlock with Name as the Child of the SelectedItem using VisualTreeHelper ?
