我在使用另一个 gridview 中的 gridview 行命令时遇到问题

问题是，当我将事件添加到另一个gridview 的项目模板中的第二个gridview 时，该事件不会运行，我怎样才能使它工作？

我的代码是：

<asp:ToolkitScriptManager runat="server" ID="MainScriptManager" />       
<asp:SqlDataSource ID="sqlDsSubCategories" runat="server"
    ConnectionString="<%$ ConnectionStrings:Scan_SystemConnectionString %>"
    SelectCommand="SP_Categoria" SelectCommandType="StoredProcedure">
    <SelectParameters>
        <asp:SessionParameter DefaultValue="01" Name="div" SessionField="DivNom" 
            Type="String" />
        <asp:SessionParameter DefaultValue="04" Name="mes" SessionField="mes" 
            Type="String" />
        <asp:SessionParameter DefaultValue="2013" Name="year" SessionField="year" 
            Type="String" />
            <asp:SessionParameter DefaultValue="042013" Name="fecha" SessionField="fecha" 
            Type="String" />
    </SelectParameters>
</asp:SqlDataSource>

    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<asp:UpdatePanel ID="pnlUpdate" runat="server">
    <ContentTemplate>
        <asp:GridView Width="100%" ID="gvSubCategories"

您必须连接子 GridView 的 RowCommand；您可以在父 GridView 的 RowCreated 事件中编写此代码，因为此事件在 Page_Load 之后和处理回发事件之前触发。

例如在 C# 中：

protected void parentGrid_RowCreated(Object sender, GridViewRowEventArgs e)

    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            childGrid = e.Row.FindControl("childGrid") as GridView;
            childGrid.RowCommand += new GridViewCommandEventHandler(childGrid_RowCommand);
        }
    }
