FIX. RadGridView - incorrect vertical scroll bar and selected row when scrolling quickly and the AutoSizeRows property is set to true
When scrolling to the bottom of the grid with the mouse, the last row is not lined up with the bottom of the grid. Also, when doing this, clicking on any row, leads to row jumping down to align properly, but a different row is selected.

Workaround:

public Form1()
{
    InitializeComponent();
    radGridView1.MouseDown+=radGridView1_MouseDown;
    radGridView1.MouseUp+=radGridView1_MouseUp;
}
bool scrolling = false;

private void radGridView1_MouseDown(object sender, MouseEventArgs e)
{
    ScrollBarThumb thumb = radGridView1.ElementTree.GetElementAtPoint(e.Location) as ScrollBarThumb;
    if (thumb != null)
    {
        scrolling = true;
    }
}

private void radGridView1_MouseUp(object sender, MouseEventArgs e)
{
    if (scrolling)
    {
        scrolling = false;
        int scrollBarValue = radGridView1.TableElement.VScrollBar.Value;
        radGridView1.MasterTemplate.Refresh();
        radGridView1.TableElement.VScrollBar.Value = scrollBarValue;
    }
}
