Hello, I have some template for cell in RadGridView:
<DataTemplate x:Key="PropEditorSet">
    <telerik:RadMenu VerticalAlignment="Top" ItemsSource="{Binding Items}" Background="Transparent">
        <telerik:RadMenu.Resources>
            <SLAdmin:SetToStringConverter x:Key="setToStringConverter"/>
        </telerik:RadMenu.Resources>
        <telerik:RadMenu.ItemTemplate>
            <DataTemplate>
                <CheckBox IsChecked="{Binding ValueString, Mode=TwoWay, Converter={StaticResource setToStringConverter}}" Content="{Binding Name}" />
            </DataTemplate>                       
        </telerik:RadMenu.ItemTemplate>
    </telerik:RadMenu>
</DataTemplate>

I see unchecked checkboxes according to Items collection after binding.
But my converter never called. Why converter never called and how I can use converter in this way? I want to use converter for processing state changes of checkboxes and pass one parameter (also using data binding) to converter.

Converter code (if I uncomment Debugger.Break lines - nothing changes - debugger don't called)
public class SetToStringConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            //Debugger.Break();
            return true;
        }
 
        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            //Debugger.Break();
            return true;
        }
    }

Thanks!

Hi,

 Converter will not be called if the binding is invalid. Please check your Visual Studio output window for more info about invalid bindings.
