[Solved] RadButtonElement subclass doesn't have correct style

[Michael]

If I subclass RadButtonElement, the subclass no longer has the same style applied as a pure RadButtonElement.  Here's the simple code snippet:

            ...
            panel.Children.Add(new RadButtonElement() { Text = "RadButtonElement" });
            panel.Children.Add(new MyRadButtonElement() { Text = "MyRadButtonElement" });
        }

        class MyRadButtonElement : RadButtonElement
        {
        }

Can you tell me how to make my RadButtonElement have the same default style (e.g. background color, mouse rollover) as a regular RadButtonElement?

Thanks,

For reference, here is the full body of my Form.OnLoad function:

        void Form1_Load(object sender, EventArgs e)
        {
            // Create element container to fill form
            RadPanel elementsContainer = new RadPanel();
            this.Controls.Add(elementsContainer);
            elementsContainer.Dock = DockStyle.Fill;
            elementsContainer.BeginInit();
            elementsContainer.EndInit();

            // Create scroll viewer for scrollbar support
            RadScrollViewer scrollViewer = new RadScrollViewer();
            elementsContainer.PanelElement.Children.Add(scrollViewer);

            // Create panel to stack buttons
            StackLayoutPanel panel = new StackLayoutPanel();
            scrollViewer.Viewport = panel;
            panel.Orientation = Orientation.Vertical;
            panel.Children.Add(new RadButtonElement() { Text = "RadButtonElement" });
            panel.Children.Add(new MyRadButtonElement() { Text = "MyRadButtonElement" });
        }

        class MyRadButtonElement : RadButtonElement
        {
        }

Hello Michael,

Thank you for the question.

When you make a class which descends from a RadButtonElement class, you should override the ThemeEffectiveType and return the type of the parent class. This will allow you to use the theming mechanism for your class:

public class MyRadButtonElement : RadButtonElement
{
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadButtonElement);
        }
    }
}

If you have additional questions, feel free to contact me.

All the best,
