Hi,
 
I'm new to WPF and C#. I've tried to seach the web for a simple tutorial or code on how I can capture the list of all the selected items in a listbox.
 
I am doing the following:
 
1. Have a List<ABC> where A has two properties: Name and Address.
2. I am using DataBinding to populate a ListBox by the following:
 
XAML:
 
<ListView Name="AddData" ItemsSource="{Binding}" DisplayMemberPath="Name" />
 
C#:
 
AddData.DataContext = XClass.getMyABCList(); // This returns the List<ABC>
 
This all works as I see the the Name property values in the ListBox.
 
Now, I want to select 3 of the items in the list. When I click on a "Done" button, I want to get the following information:
 
1) The indexes of the selected items
2) The Name values of the selected items
3) The Address values of the selected items.
 
I can obtain (2) and (3) if I can get (1) as I can cross reference the master List
 
Would appreciate any help in this.
 
Thanks,
 
Manish

Rather than attempting to do this in a Win Forms manner, you can achieve this in a WPF-centric way by adding an IsSelected property to the class behind the list. Then you bind to this property using the following:
<ListBox.ItemContainerStyle>
  <Style TargetType="{x:Type ListBoxItem}">
     <Setter Property="IsSelected" Value="{Binding Mode=TwoWay, Path=IsSelected}"/>
  </Style>
</ListBox.ItemContainerStyle>
Now your underlying list will have the IsSelected boolean set as appropriate, and you can just select the items where that value is set.

Dude, Thanks a lot for this. I wouldn't have figured this out given that I am new to WPF and C#.
 
Can you kindly recommend any books or references on learning material....this would help greatly....Thanks again!!!

Don't worry about it mate - we all had to start somewhere, and this stuff isn't obvious when you first start off. As for books, I'd recommend WPF Unleashed by Adam Nathan and Pro WPF in C# 2010 by Matthew MacDonald. Welcome to the world of WPF - it's one wild ride.
