about drag and drop event while reordering columns

[ejaz]

Hi,
I am using GridGrouping and need to store sequence of the columns in a collection.I am able to change the position of the column or can reorder but not getting any event for that to get the column which is being moved to another posiion.I need to change the order of the columns and store them in some collection so that next time if I bind grid to the datasource it should display columns in new order which is changed last time.

Regards,
Ejaz

Hi Ejaz,

Please try handling TableControlQueryAllowDragColumn event hanlder and see if it helps.

private void gridGroupingControl1_TableControlQueryAllowDragColumn(object sender, GridQueryAllowDragColumnEventArgs e)
{
Console.WriteLine("gridGroupingControl1_TableControlQueryAllowDragColumn");
}

Kindly let us know if this helps.

Best Regards,

Hi Ejaz,

Please try this code snippet to get the column which is moved to another position.

private void gridGroupingControl1_TableControlQueryAllowDragColumn(object sender, GridQueryAllowDragColumnEventArgs e)
        {

            if (e.Reason == GridQueryAllowDragColumnReason.MouseUp)
            {
                Console.WriteLine("gridGroupingControl1_TableControlQueryAllowDragColumn");
                Console.WriteLine("Moved Column="+ e.Column.ToString());
            }
        }

Best Regards,
Jeba.
