Using one scroll bar to control two DataGridView

问题:

I am trying to control two DataGridView's with only one of the DataGridView vertical scroll bars being visible.

回答1:

protected void grid1_Scroll(object sender, ScrollEventArgs e)
{
    grid2.VerticallScrollBar.Value = e.NewValue;
}

回答2:

If both DataGridView controls have equal number of rows, you can do the following. I am using this to compare two SQL resultsets side by side.

Set Scroll event handlers on both controls.

private void DataGridView1_Scroll(object sender, ScrollEventArgs e)
{
    DataGridView2.FirstDisplayedScrollingRowIndex =
        DataGridView1.FirstDisplayedScrollingRowIndex;
}

private void DataGridView2_Scroll(object sender, ScrollEventArgs e)
{
    DataGridView1.FirstDisplayedScrollingRowIndex =
        DataGridView2.FirstDisplayedScrollingRowIndex;
}

回答3:

In Form.Load():

Grid1.Scroll += (s, ev) => Grid2.VerticalScrollBar.Value = Grid1.VerticalScrollBar.Value;

Edit: We can't assign Grid2.VerticalScrollingOffset as I had originally suggested, as it's a ReadOnly property.
