Grid Scroll

[Ravi]

Hi,

Is there any DataBoundGrid event which fires after Scroll thumb in a grid is dragged and released. The event iam looking should not fire for any other scroll action.

Thanks,
Ravi.

Hi Ravi,

Maybe the VScrollBar.Scroll (or HScrollBar.Scroll) event will get you what you need. In that event, you can use e.Type property to detect the scrollbox is being moved by ThumbTrack. Below are the codes:

this.grid.VScrollBar.Scroll += new ScrollEventHandler(VScrollBar_Scroll);


void VScrollBar_Scroll(object sender, ScrollEventArgs e)
{
if (e.Type == ScrollEventType.ThumbTrack)
{
Console.WriteLine("Scrollbox is being moved by ThumbTrack");
}
}


Let me know if this helps.

Best regards,
Haneef

Hi Haneef,

How can i move the grid current cell focus to the first visible row and column after the scroll thumb is moved.

Thanks,

Try code such as this:

        private bool thumbPositionSet = false;
        void VScrollBar_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.Type == ScrollEventType.ThumbPosition)
            {
                thumbPositionSet = true;
            }
            else if(e.Type == ScrollEventType.EndScroll && thumbPositionSet)
            {
                thumbPositionSet = false;
                this.gridControl1.CurrentCell.MoveTo(gridControl1.TopRowIndex, gridControl1.LeftColIndex);
            } 
        }
