Binding SelectItem Content

Question

I have a listbox that populates expander controls the header and content is binded. I want to be able to SelectItem to a TextBlock.. Currently I'm using {Binding SelectedItem.Content, ElementName=Listbox}. I tried binding to the expander and the textbox that the Expanders populates in the expander. But no results.

Any Thoughts?

Hi Instead of using SelectedItem.Content try using SelectedItem only. Since the data is binded using XML data source you should a value converter for doing some data extraction. For create a class which inhererits from IvalueConverter. public class XmlValueConverter:IValueConverter { #region IValueConverter Members public object Convert(object value Type targetType object parameter CultureInfo culture) { ///Write your logic return value; } public object ConvertBack(object value Type targetType object parameter CultureInfo culture) { throw new NotImplementedException(); } #endregion } and XAML xmlns:local=clr-namespace:XamlDataProvider Listbox  Mode=OneWay Path=SelectedItem Converter={StaticResource XmlValueConverter }> while running the application try putting breakpoint and check the result such that it would help you in writing your logic Regards raaj

Thank you for your help  but it errors on the Local:Xml Value Converter. it doesn't exist in the clr- namespace:XmlDataProvidor. Any thoughts?
