GridView中的RowCommand事件中的取值问题

先看前台代码

 <asp:GridView runat=\"server\"  ID=\"GridView1\" CssClass=\"Result_tab\" AutoGenerateColumns=\"False\" DataSourceID=\"SqlDataSource1\" DataKeyNames=\"id\" OnRowCommand=\"GridView1_RowCommand\">
            <Columns>
 <asp:TemplateField HeaderText=\"有效时间\" SortExpression=\"audit\">
                    <EditItemTemplate>
                        <asp:TextBox ID=\"TextBox8\" runat=\"server\" Text=\'<%# Bind(\"audit\") %>\'></asp:TextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:TextBox ID=\"TextBox9\" runat=\"server\" Text=\'<%# Bind(\"effective_time\") %>\' Width=\"50\" ></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>

                 <asp:TemplateField HeaderText=\"审批\">
                                    <EditItemTemplate>
                                        <asp:TextBox ID=\"TextBox10\" runat=\"server\" Text=\'\'></asp:TextBox>
                                    </EditItemTemplate>
                                    <ItemTemplate>
                                        <asp:Button runat=\"server\" ID=\"orderManage\" Text=\"通过\" CommandName=\"Modify\" CommandArgument=\'<%# Bind(\"id\") %>\' />
                                        <asp:Button runat=\"server\" ID=\"Button3\" Text=\"不通过\" CommandName=\"Forbid\" CommandArgument=\'<%# Bind(\"id\") %>\' />
                                    </ItemTemplate>
                                </asp:TemplateField>
                  <asp:TemplateField HeaderText=\"审批备注\" SortExpression=\"audit\">
</Columns>
        </asp:GridView>

　　要在 GridView1_RowCommand 方法中取TextBox9的值，无法直接取。

这个时候要用下面的办法

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        string workid = e.CommandArgument.ToString();
        string name = e.CommandName.ToString();
        string strUpdate = \"\";
        string strRemark = \"\";
        string strEffective = \"\";

        GridViewRow row = ((Control)e.CommandSource).BindingContainer as GridViewRow;
        //取有效时间
        TextBox txtEffectiveTime = (TextBox)row.FindControl(\"TextBox9\");
        strEffective = (string.IsNullOrEmpty(txtEffectiveTime.Text) != true) ? txtEffectiveTime.Text.Trim() : \"\";
        //取审备注
        TextBox txtNotion = (TextBox)row.FindControl(\"TextBox12\");
        strRemark = (string.IsNullOrEmpty(txtNotion.Text) != true) ? txtNotion.Text.Trim() : \"\";
}

　　最有效的就是这段

GridViewRow row = ((Control)e.CommandSource).BindingContainer as GridViewRow;

//如果要去id为TextBox9的值

TextBox txtEffectiveTime = (TextBox)row.FindControl(\"TextBox9\");
