DragDrop behaviour in ButtonElement

[Antonis]

Hi,
I am using a ButtonElement to draw draggable images on a panel
The problem is that the ButtonElement does not expose DrogOver,DragDrop methods so I cannot know when one ButtonElement is dragged over another.

Is there any solution?

Thanks in advance

Hello Antonis,

You can find out whether you are dragging over an element by handling DragOver event of RadControl in which the element is positioned and use GetElementAtPoint() method of the rad control ElementTree property. For example:

void radListBox1_DragOver(object sender, DragEventArgs e)
{
    RadElement elementdUnderMouse = this.radListBox1.ElementTree.GetElementAtPoint(this.radListBox1.PointToClient(new Point(e.X, e.Y)));
    if (elementdUnderMouse != null && elementdUnderMouse is RadListBoxItem)
    {
        // Do work with the element.
    }
}

Please write again if you have other questions.
