How to scroll a DataGridView?

DataGridView has HorizontalScrollBar and VerticalScrollBar properties, but they are protected. It also has a public read/write HorizontalScrollingOffset property, which works great at programaticaly scrolling the DataGridView horizontally. The VerticalScrollingOffset property, however, is read only. I need a way to scroll DataGridView vertically or horizontally x amount of pixels programatically. I tried to SendMessage WM_VSCROLL to the control, but that did not do anything.

Example:

private int WM_VSCROLL = 0x0115;
private int SB_PAGEDOWN = 3;
private int SB_LINEDOWN = 1;
       
[DllImport("user32")]
private static extern int SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);

Try to scroll:
---------------
SendMessage(this.dataGridView1.Handle, WM_VSCROLL, (IntPtr)SB_PAGEDOWN, IntPtr.Zero);


Please help.

Here is a thought:

using System.Reflection;

...


PropertyInfo verticalOffset = this.dataGridView1.GetType.GetProperty("VerticalOffset", BindingFlags.NonPublic | BindingFlags.Instance);

// Set the scroll offset to 10.
verticalOffset.SetValue(this.dataGridView1, 10, null)

Hi,

This is not pixel based, so I'm not sure that it will help you, but the FirstDisplayedScrollingRowIndex property on the DataGridView has usually done everything I've needed for setting the scrolled location.

Hope this helps

Thanks, Nick, there are so many properties and so little time to discover them all.
