    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"/>

    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.
