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");
