How to Drag and Drop in the GridGroupingControl?


To implement the Drag and Drop function in the GridGroupingControl, you have to handle the Control.DragOver and Control.DragDrop events. In the following example, the TableControlMouseDown event is handled to start the dragdrop operation that occurs only when the mousedown is over a RecordRowHeaderCell. In the Control.DragDrop event, the selected records are added to the target Grid. With the cursor coordinates, the row and column of the target Grid can be found. By using the row and column, the celltype can be found. When the cell type is RecordFieldCell, then the records in the DataObject can be pasted.


To drag and drop in the GridGroupingControl, set the AllowDrop property to true and handle DragDrop, DragOver, and TableControlMouseDown events. The following code example explains how the dragdrop operation works in the GridGroupingControl.
