Modify appearance of RadComboBoxes in RadDataForm

[Peter]

I have a DataForm with various DataFormComboboxFields. I'm using autogeneration to populate the DataForm.

How can I change the appearance of RadComboBoxes in the DataFormComboBoxFields at runtime?

I want to be able to show or hide the SelectionButton that appears inside the ComboBoxes (Property ClearSelectionButtonVisibility  of RadComboBox). Some DataFormComboBoxFields should show this button, others not...

Hello Peter,

You can try the following approach:

private void DataForm1_AutoGeneratingField(object sender, Telerik.Windows.Controls.Data.DataForm.AutoGeneratingFieldEventArgs e)
      {
          if (e.PropertyName == "Gender" )
          {
              e.DataField.Loaded += new RoutedEventHandler(DataField_Loaded);
          }
      }
      void DataField_Loaded(object sender, RoutedEventArgs e)
      {
          (sender as DataFormComboBoxField).Loaded -= new RoutedEventHandler(DataField_Loaded);
          ((sender as DataFormComboBoxField).Content as RadComboBox).ClearSelectionButtonVisibility = Visibility.Visible;
          ((sender as DataFormComboBoxField).Content as RadComboBox).ClearSelectionButtonContent = "Clear Button";
      }

Please check the attached sample project for a reference.
