尝试这个

将按钮 btnyes 的 CommandName 设置为“选择”
将 OnSelectedIndexChangedevent 添加到 gridview
点击 btnyes 将触发 GeidView 的 OnSelectedIndexChangedevent 事件。

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