c# - listview 数据绑定字母顺序

Question

我需要订购我的类别标题 -

( <%#Eval("CategoryDe​​scription").ToString().ToUpper()%> )

按字母顺序。我该怎么做呢？谢谢！

下面是 C# 中的代码：

    protected void lstvwFileCategory_OnItemDataBound(Object sender,   
    ListViewItemEventArgs e)
    {
        if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            ListViewDataItem temp = (ListViewDataItem)e.Item;
            Files.HAHADocument_Category catdata =   
            (Files.HAHADocument_Category)temp.DataItem;

            ListView files = new ListView();
            files = (ListView)e.Item.FindControl("lstvwFiles");

            files.DataSource = catdata.Documents;
            files.DataBind();
        }
     }

这是代码本身：

     <asp:ListView runat="server" ID="lstvwFileCategory"  
     OnItemDataBound="lstvwFileCategory_OnItemDataBound">
          <LayoutTemplate>
              <asp:Literal runat="server" ID="itemPlaceholder" />
          </LayoutTemplate>
          <ItemTemplate>
               <div class="linksection">
                    <h2><%#Eval("CategoryDescription").ToString().ToUpper()%></h2>
                    <asp:ListView runat="server" ID="lstvwFiles"  
                    OnItemDataBound="lstdvwFiles_OnItemDataBound">
                         <LayoutTemplate>
                             <asp:Literal runat="server" ID="itemPlaceholder" />
                         </LayoutTemplate>
               </div>
          </ItemTemplate>
     </asp:ListView>

和

 if (PageID > 0)
    {
        HAHA_BLL.FileRepository.Files fls = new HAHA_BLL.FileRepository.Files();
        lstvwFileCategory.DataSource =  
        fls.GetHAHADocument_Categories((int)PageID);
        lstvwFileCategory.DataBind();
    }

Answer 1

using System.Linq;在代码隐藏文件的顶部添加，然后将数据源分配更改为：

lstvwFileCategory.DataSource = fls.GetHAHADocument_Categories((int)PageID)
                                    .OrderBy(c => c.CategoryDescription);
