All I have a problem that I want to make the VerticalScrollBar not scroll in Datagridview when I make the mouse wheeling.

I have get some codes like this:

  private void dgwFlowerPics_MouseWheel(object sender, MouseEventArgs e)
    {
        int iRowIndex = iSelectedIndex;

        if (e.Delta > 0) 
        {
            SendKeys.Send("{UP}");  


        }
        else 
        {
            SendKeys.Send("{DOWN}"); 
        }
    }

But the scrollBar still scrolls when I wheel the mouse.How I can resolve it ?

I think this is similar to C# - how do I prevent mousewheel-scrolling in my combobox?

In your event code you can do

    void dataGridView1_MouseWheel(object sender, MouseEventArgs e)
    {
        ((HandledMouseEventArgs)e).Handled = true;
    }

after binding the event of course:

dataGridView1.MouseWheel += new MouseEventHandler(dataGridView1_MouseWheel);
