I know it'll be simple for you guys| call takes 1 overload???

Question

Hi,
Just wondering if you could tell me what im meant to put in the Call() brackets.
 
private void Call(DataGridViewCellEventArgs o)
{
int rowIndex = o.RowIndex;
string t = dataGridView2.Rows[o.RowIndex].Cells["Name"].Value.ToString();
textBox1.Text = t;
}
private void button3_Click(object sender, EventArgs e)
{
Call();
}
}
Thanks
Anthony
