How to disable a context menu when clicking on DataGridView header

Question

I've created a context menu and named it GridMenu, I then set the ContextMenuStrip property of a DataGridView to GridMenu. I only want the context menu to show when right-clicking on the data rows of that DataGridView. Not its column headers.

So how do I disable the context menu if any of the column headers are right-clicked?

Answer 1

private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
{
        if (DataGridView1.CurrentRow.Index < 0)
            e.Cancel = true;
}

Answer 2

Write this in your Form load event:

 foreach (DataGridViewRow gridViewRow in dataGridView1.Rows)
        {
            gridViewRow.ContextMenuStrip = contextMenuStrip1;
        }
