Hi Gourav,

I am not sure of what be might be causing this strange behavior without a working sample. I have tested this issue in browser sample with Essentail studio V.4.x/5.x. But i was not able to reproduce the issue. Is it possible for you to upload us a minimal sample or modify the browser sample to reproduce the issue here? This will help us to analyse the issue further.

Best regards,
Haneef

Hi Gourav,

Thanks for your patience.

You could resolve this problem by handling the QueryAllowDragColumnHeader event of the GridDataBoundGrid. Also, set the ResizeColsBehavior to AllowDragOutside, to enable dragging the column separator beyond the parent container. Please try the code below.

// Form_Load
this.gridDataBoundGrid1.ControllerOptions |= GridControllerOptions.DragColumnHeader;
this.gridDataBoundGrid1.ResizeColsBehavior = GridResizeCellsBehavior.AllowDragOutside;

// QueryAllowDragColumnHeader event

void gridDataBoundGrid1_QueryAllowDragColumnHeader(object sender, GridQueryDragColumnHeaderEventArgs e)
{
    if (e.Reason == GridQueryDragColumnHeaderReason.MouseUp)
    {
        if (e.InsertBeforeColumn > this.gridDataBoundGrid1.Model.ColCount)
        {
            e.AllowDrag = false;
            e.Grid.Model.Cols.MoveRange(e.Column, this.gridDataBoundGrid1.Model.ColCount);
        }
    }
}

Let me know if this helps.

Have a nice time.
