在asp.net C#中按行号对GridView排序？

c# asp.net sorting gridview

在asp.net C#中按行号对GridView排序？,c#,asp.net,sorting,gridview,C#,Asp.net,Sorting,Gridview,我在ASP.NET中有一个带有行号（Container.DataItemIndex）列的GridView（1,2,3,4，…）我通过以下代码在GridView中添加了它： <asp:TemplateField HeaderText="#" SortExpression="#"> <ItemTemplate> <%# Container.DataItemIndex + 1 %> </ItemTemplate>

我在ASP.NET中有一个带有行号（Container.DataItemIndex）列的GridView（1,2,3,4，…）

我通过以下代码在GridView中添加了它：

<asp:TemplateField HeaderText="#" SortExpression="#">
     <ItemTemplate>
          <%# Container.DataItemIndex + 1 %>
     </ItemTemplate>
</asp:TemplateField>

我怎么做

编辑：
我是这样做的，但它将列排序为

1,11,12,13，…，2,21,22，

我想对#列

1,2,3，…，11,12,13，…

（一开始声明式排序比较容易，但学习编程方式也很好）

听起来像是按字符串排序，这样行吗

<ItemTemplate> 
    <%# Convert.ToInt32(Container.DataItemIndex + 1) %> 
</ItemTemplate>

我使用了以下方法解决了我的问题：
