Question

I have a ComboBox hosted in a ListView and I need changes in the CombBox to update the supporing class that the ListView is bound to.

Here is my DataTemplate

<DataTemplate x:Key='Category'>     <ComboBox IsSynchronizedWithCurrentItem='False'                Style='{StaticResource DropDown}'                ItemsSource='{Binding Source={StaticResource Categories}}'               SelectedValuePath='Airport'               SelectedValue='{Binding Path=Category}'               />     </DataTemplate> 

This is the Listview. The ItemSource for the ListView is a collection of Airports and is set in code behind, and has a property called Category that I need the combobox to update.

<ListView.View>             <GridView>                 <GridViewColumn DisplayMemberBinding='{Binding Path=Name}' Header='Airport' Width='100' />                 <GridViewColumn Header='Category' Width='100'  CellTemplate='{StaticResource Category}' />             </GridView>         </ListView.View>

Why have you set SelectedValuePath in your ComboBox? It’s difficult to say without seeing your data structures, but that doesn’t look right to me.
