RadPanels Drag and Drop

[R]

Hi.

I have a  RadPanel with several RadPanels inside. I want to be able to drag and drop the RadPanels to change their location inside the main RadPanel. Can you help me with that?

Thanks

Hello,

Thank you for contacting us.

A possible solution would be to use a descendant class of the RadPanel and override the OnMouseMove method. This behavior is demonstrated in the following code snippet:

    public class MyPanel : RadPanel
    {
        Point downPoint;

        protected override void OnMouseDown(MouseEventArgs e)
        {
            base.OnMouseDown(e);
            downPoint = e.Location;
        }

        protected override void OnMouseMove(MouseEventArgs e)
        {
            base.OnMouseMove(e);
            if (e.Button == MouseButtons.Left)
            {
                Point delta = new Point(e.X - downPoint.X, e.Y - downPoint.Y);
                Console.WriteLine("Delta: x = {0}, y = {1}", delta.X, delta.Y);
                this.Location = new Point(this.Location.X + delta.X, this.Location.Y + delta.Y);
            }
        }

        public override string ThemeClassName
        {
            get
            {
                return typeof(RadPanel).FullName;
            }
            set
            {
            }
        }
    }

I hope this helps. Do not hesitate to write me if you have any other questions.
