WPF: data binding to DataGridComboBoxColumn

Question

This is what I want:

• There is a list column bound to the ApplicationKey property of ClassA
• The combo box is filled with ApplicationTokens from a static function.
• ApplicationToken has property ApplicationName and ApplicationKey
• When an item is selected from the drop-down list, the ClassA.ApplicationKey property is set to ApplicationToken.ApplicationKey on the selected item.

This is my current code that populates combobox but does not update ClassA.ApplicationKey.

<DataGridComboBoxColumn 
    Header="Application" 
    SelectedItemBinding="{Binding ApplicationKey, Converter={gui:DebugConverter}}" 
    SelectedValuePath="ApplicationKey" 
    DisplayMemberPath="ApplicationName" 
    ItemsSource="{Binding Source={x:Static app:ApplicationLookup.GetAllOrNone}}"/>

Answer 1

SelectedValueBinding SelectedItemBinding SelectedValuePath.

<DataGridComboBoxColumn 
    Header="Application" 
    SelectedValueBinding="{Binding ApplicationKey}"
    SelectedValuePath="ApplicationKey" 
    DisplayMemberPath="ApplicationName" 
    ItemsSource="{Binding Source={x:Static app:ApplicationLookup.GetAllOrNone}}"/>
