Hello Milko,

Thank you for your support. The code provided by you is working fine, which almost serves my purpose. But as per my requirement, I need to rearrange the rows in single grid by dragging and dropping. After adding your code in my application, grid is scrolling automatically, but the scroll speed is very fast. This creates problems for me in the following scenario:

Suppose there are 100 rows, and i want to move row #2 to row #75, and suppose there are 20 rows in the visible region. Now when I start dragging row #2, I reach the end of visible region, the grid starts scrolling down, but it scrolls so fast that I always reach the end of the rows, but ideally the scroll speed should be slower, so that I can stop scrolling when I see row #75.

This is really important for my application that grid scrolls slower. Again Looking forward to have valuable feedback from your side. 

Hello Sumit,

I am just checking about the progress of this issue. Let me know if you need our further assistance on it.

Thank you for using Infragistics Components.

Rajivd,

If you want to cut the scroll speed in half, you could use a boolean variable to only have the logic to scroll executed every other time the event fires:

bool shouldScroll = true;
void ultraGrid1_DragOver(object sender, DragEventArgs e)
{
 if (shouldScroll)
 {
  Point point = grid.PointToClient(new Point(e.X, e.Y));
  if (point.Y < 20)
  {
   // Scroll up.
   this.ultraGrid1.ActiveRowScrollRegion.Scroll(RowScrollAction.LineUp);
  }
  else if (point.Y > grid.Height - 20)
  {
   // Scroll down.
   this.ultraGrid1.ActiveRowScrollRegion.Scroll(RowScrollAction.LineDown);
  }
    }
    shouldScroll = !shouldScroll;
}

Other alternatives that you could look into would be using a timer to do the scrolling so that the user wouldn't need to move the mouse continuously for the grid to keep scrolling.
