Drag & Drop on grouped GridView

[Thomas Van den Bossche]

Dear,

I have a question regarding drag & drop on a grouped GridView.
The drag & drop functionality (drag & drop between two GridViews) works but now I want to drag on the header of a group.
I need to get the ID or text of the header group.

private void gridAssigned_DragDrop( object sender, DragEventArgs e ) {
            if ( e.Data.GetDataPresent( typeof( GridViewDataRowInfo ) ) ) {
                // dropped on which group?
                // need ID or text...
                GridViewRowInfo droppedDriver = GetRowAtPoint( gridAssigned, gridAssigned.PointToClient( new Point( e.X, e.Y ) ) );
                // row I'm dragging
                GridViewDataRowInfo draggedInfo = ( GridViewDataRowInfo )e.Data.GetData( typeof( GridViewDataRowInfo ) );
            }
        }

private GridViewRowInfo GetRowAtPoint( RadGridView grid, Point location ) {
            RadElement element = grid.ElementTree.GetElementAtPoint( location );

            // headercells are for grouping
            if ( element is GridHeaderCellElement ) { return null; }
            if ( element is GridCellElement ) { return (( GridRowElement )element).RowInfo; }

            return null;
        }

Thanks in advance!

Hi Thomas,

Thank you for contacting us. You can use code similar to this one:

void radGridView1_MouseDown(object sender, MouseEventArgs e)
{
    GridCellElement cell = this.radGridView1.ElementTree.GetElementAtPoint(e.Location) as GridCellElement;
    if (cell != null)
    {
        GridViewGroupRowInfo groupRow = cell.RowInfo as GridViewGroupRowInfo;
        if (groupRow != null)
        {
            string text = groupRow.GetSummary();
            //...
        }
    }
}

If you have more questions, please write me back.
