网格视图中 ASP.NET 模板字段错误

Question

我有一个有效的网格视图，数据绑定列提取正确的信息，但是当我尝试添加模板字段时，我在浏览器中收到以下错误：

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS1061: 'ASP.componentcontrols_userdetails_detailgridcontrol_ascx' does not contain a definition for 'gwOrderInvQuote_SelectedIndexChanged' and no extension method 'gwOrderInvQuote_SelectedIndexChanged' accepting a first argument of type 'ASP.componentcontrols_userdetails_detailgridcontrol_ascx' could be found (are you missing a using directive or an assembly reference?)

网格视图我这样声明它：

     <asp:View ID="Foo" runat="server">
                <asp:GridView ID="Foo" runat="server" DataKeyNames="id"
                    DataSourceID="odsFoo" Width="631px" OnRowDataBound="gwFoo_RowDataBound"
                    CssClass="customerDataTable" AllowSorting="True" 
                    onselectedindexchanged="gwOrderInvQuote_SelectedIndexChanged">
                    <Columns>

模板字段我声明为：

 <asp:TemplateField AccessibleHeaderText="fhfj">
            <HeaderTemplate> This is a Test </HeaderTemplate>
            <ItemTemplate> </ItemTemplate>
 </asp:TemplateField>

我试图实现的效果是将按钮与网格完美对齐，

到目前为止，我的策略是创建此模板字段并在标题中插入，将所有其他单元格留空，该列没有其他目的，只能容纳按钮以便它与网格对齐。

问题是这是我第一次使用网格视图和模板化字段，甚至这个简单的测试以查看我是否可以创建一个空列也不起作用。

您必须在 cs 文件中定义方法gwOrderInvQuote_SelectedIndexChanged：

 protected void gwOrderInvQuote_SelectedIndexChanged(object sender, EventArgs e)
 {
 // insert logic here
 }
