Hello,

I created a custom GridViewDataColumn like this:
public class EmpGridViewActionColumn : EMPGridViewDataColumn
{
    public static readonly DependencyProperty ActionsProperty =
        DependencyProperty.Register(
        "Actions",
        typeof(IList<ActionData>),
        typeof(EMPGridView),
        new PropertyMetadata(null, new PropertyChangedCallback(ActionsValueChange))
     );
 
    public IList<ActionData> Actions
    {
        get { return (IList<ActionData>)GetValue(ActionsProperty); }
        set { SetValue(ActionsProperty, value); }
    }
 
    private static void ActionsValueChange(DependencyObject source, DependencyPropertyChangedEventArgs e)
    {
        if (e.NewValue != null)
        {
            ((EmpGridViewActionColumn)source).Actions = (IList<ActionData>)e.NewValue;
            ((EmpGridViewActionColumn)source).ApplyEmpGridViewActionColumnTemplate();
        }
    }
}

And in xaml:
   
<myControls:EmpGridViewActionColumn Header="Type" Width="120">
                <myControls:EmpGridViewActionColumn.Actions>
                    <myControls:EMPActionDataContract Name="Test"/>
                </myControls:EmpGridViewActionColumn.Actions>
            </myControls:EmpGridViewActionColumn>
At run time: I encounter error at line:
<myControls:EMPActionDataContract Name="Test"/>

Does anyone have any idea or solution?

Hello Tuan Anh,

Can you please clarify how is that problem specifically related to Telerik controls? If you do the same thing on another object does your XAML work?

Best wishes,
