Hi

I need to drag and drop from / to  GridViewColumnGroup of RadGridView.

I haven't found any example or guide how to do it.

Setting up DragDropManager events (like DragInitializeHandler, DropHandler ... ) to RadGridView doesn't work on GridViewColumnGroup.

Drag and drop from / to GridViewCells and GridViewHeaderCells works, but GridViewColumnGroup doesn't.

Does anyone know how to drag and drop from / to GridViewColumnGroup?

Hi Michal,

I am afraid that you can not drag/drop ColumnGroup since reordering of GridView's ColumnGroups is not supported. The supported feature is - Reordering Columns.

I don't need feature like reordering column groups, I need to implment custom drag and drop (using DragDropManager).

I just need to make somehow column groups dragable and dropable.

Is there any workaround? (like editing default column group style?? .. etc.) Or it is absolutely impossible?

Hello Michal,

I am afraid that I can not understand the exact scenario. Would it be possible to share more details about it? What do you expect to happen after drop of the columnGroup.?

I expect:

be able to drop to column ​group (and recognize that I dropped to column group, not to other control)

be able to drag from column group (and recognize that ​I dragged from column group, not from other control)

events that I subscribed are raised (from DragDropManager like DragOver, DropCompleted ... etc.)

what should happen after drag or drop is implmented in event handlers of events that I subscribed

so it's something like custom column group drag and drop using DragDropManager

Hello Michal,

Thank you for clarifying.

Unfortunately, custom drag and drop of a ColumnGroup element is not possible.
