sir, as your heading say "
how to fire click event for datagridview cells" and you have already made the function
private void dataGridView2_Click(object sender, DataGridViewCellEventArgs e)
if still
dataGridView2_Click is not firing on
click event of datagridview you should go to the
Event's of datagridview -> check if "
dataGridView2_Click" is written in front of the
Click event
