Handle click event on DGV header?

Question

C++ / C#

Good afternoon. I'm using the RowHeaderMouseClick event to call the context menu in the DGV. But when you click on this area of ​​the selected area , the event does not occur. In general, it is clear why. The question is, what event to process when clicking on this area?

Answer 1

Handle the generic CellMouseClick event . The cell selected in the screenshot has both indices equal to -1:

private void DataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    var row = e.RowIndex;
    var column = e.ColumnIndex;

    if(row == -1 && column == -1)
    {
        // Do something
    }
}

Answer 2

In theory, this is the header area of ​​the table grid. Have you tried DataGridView.ColumnHeaderMouseClick?
