    protected void divide(object sender, EventArgs e)
            {

            }

Answer 1

Try this

Set CommandName as 'select' for the Button btnyes
Add OnSelectedIndexChangedevent to gridview
Clicking the btnyes will trigger OnSelectedIndexChangedevent event of the GeidView.

protected void Gridview2_SelectedIndexChanged(object sender, EventArgs e)
{
    TextBox txtboxtotal = (TextBox)Gridview2.SelectedRow.FindControl("txtboxtotal");
    txtboxtotal.Text = (Convert.ToDecimal(txtboxtotal.Text) / 2).ToString();
}

在gridview中除以一个值
