C# gridview中的排序事件未激发

我在谷歌上搜索了很多次，但是没有任何关于我的解决方案的有用链接。我有AllwSorting=“true”和OnSort函数。今天我发布这个问题，谢谢你的帮助。 这是我的ASCX：

<asp:GridView ID="gvwCus" runat="server" CssClass="gridview" AlternatingRowStyle-CssClass="even" AutoGenerateColumns="false" GridLines="Vertical" AllowPaging="false" OnRowCommand="RowCommand" AllowSorting="true" OnSorting="gvwCus_OnSorting">
  <Columns>
     <asp:TemplateField ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" HeaderStyle-Width="4%">
        <HeaderTemplate>STT</HeaderTemplate>
        <ItemTemplate>
          <asp:Label ID="lblId" runat="server" Text="<%#Container.DataItemIndex + 1%>"></asp:Label>
        </ItemTemplate>
     </asp:TemplateField>
     <asp:BoundField HeaderStyle-Width="12%" DataField="field1" HeaderText="Field1_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
     <asp:BoundField HeaderStyle-Width="30%" DataField="field2" HeaderText="Field2_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
     <asp:BoundField HeaderStyle-Width="31%" DataField="field3" HeaderText="Field3_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
     <asp:BoundField HeaderStyle-Width="20%" DataField="field4" HeaderText="Field4_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center" />
     <asp:CommandField HeaderStyle-Width="2%" ButtonType="Image" SelectImageUrl="~/Images/detail.png" ShowSelectButton="true" />
  </Columns>
</asp:GridView>

谢谢

您没有为要排序的列设置排序表达式。添加SortExpression，您将看到每个列的超链接。单击这些链接将触发排序事件。添加sortexpression后，您的边界字段应如下所示：

 <asp:BoundField SortExpression="field1" HeaderStyle-Width="12%" DataField="field1" HeaderText="Field1_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
 <asp:BoundField SortExpression="field2" HeaderStyle-Width="30%" DataField="field2" HeaderText="Field2_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
 <asp:BoundField SortExpression="field3" HeaderStyle-Width="31%" DataField="field3" HeaderText="Field3_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
 <asp:BoundField SortExpression="field4" HeaderStyle-Width="20%" DataField="field4" HeaderText="Field4_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center" />

呈现的标题应如下所示：

你怎么知道事件没有触发？@EmmadKareem:我在gvwCus_OnSorting函数上设置了断点。网格也会对数据进行排序，但事件没有触发？绑定代码在哪里？@EmmadKareem:bind data是DataBind函数。数据为：data=dataOracle.GetDataTable（）。我在谷歌上搜索到，当我点击标题时，事件运行到gvwCus_排序函数断点，但我的代码没有触发。这是我的问题，太棒了。非常感谢！！

 <asp:BoundField SortExpression="field1" HeaderStyle-Width="12%" DataField="field1" HeaderText="Field1_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
 <asp:BoundField SortExpression="field2" HeaderStyle-Width="30%" DataField="field2" HeaderText="Field2_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
 <asp:BoundField SortExpression="field3" HeaderStyle-Width="31%" DataField="field3" HeaderText="Field3_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/>
 <asp:BoundField SortExpression="field4" HeaderStyle-Width="20%" DataField="field4" HeaderText="Field4_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center" />
