[Solved] RadPropertyGrid problem with EditorTemplate in Single EditMode

[Eugene]

In my project I use RadPropertyGrid. I can't set custom editors in xaml because I don't know properties of PropertyGrid.Item in design mode.
I defined PropertyDefinition and set EditorTemplate in run time.

<DataTemplate x:Name="CustomComboBox">
   <ComboBox telerik:AutoBindBehavior.UpdateBindingOnElementLoaded="SelectedValue" SelectionMode="Single" Loaded="ComboBox_Loaded"/>
</DataTemplate>

I have dynamically set some properties of Editors in Loaded() event (for example ItemsSource for ComboBox).

I use PropertyGridField.AutoGeneratedPath to define witch editor is loading.

private void ComboBox_Loaded(object sender, RoutedEventArgs e)
{
   string propertyName = ((PropertyDefinition)((PropertyGridField)((ComboBox)sender).Parent).DataContext).AutoGeneratedPath;
   //creating itemsList...
   ((ComboBox)sender).ItemsSource = itemsList;
   ((ComboBox)sender).DisplayMemberPath = "DisplayName";
   ((ComboBox)sender).SelectedValuePath = "Code";
}

In EditMode="Default" it works fine.

If I set EditMode to Single this solution will not work.

In Loaded() event sender.Parent = null.

Hello Sergei,

Here is an alternative approach for getting the bound property which will work in both edit modes:

var comboBox = sender as ComboBox;
var pd = comboBox.ParentOfType<PropertyGridField>().DataContext as PropertyDefinition;
var propertyName = pd.AutoGeneratedPath;

Please let me know if this would work for you. If that is not the case, please provide more details regarding you exact requirements and I will gladly guide you further in finding a solution for your particular scenario.
