使用一个滚动条控制两个DataGridView

Question

我正在尝试控制两个DataGridView，仅其中一个DataGridView垂直滚动条可见。

Answer 1

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

Answer 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;
}

Answer 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.
