C# gridview排序顺序在编辑行时更改

我有一个gridview，它只是根据dropdownlist中的过滤器显示记录，当我更改dropdownlist时，页面回发良好，过滤器工作正常，但当我单击编辑行时，排序顺序会根据新过滤器更改。当我将下拉列表更改回原始过滤器并单击“编辑”时，排序顺序保持不变

有什么想法吗

<asp:DropDownList ID="ddlFilterDocs" runat="server" 
                     AutoPostBack="True" 
                     onselectedindexchanged="ddlFilterDocs_SelectedIndexChanged">
                                      <asp:ListItem Text="MissingData" 
Value="MissingData" >MissingData</asp:ListItem>
                                       <asp:ListItem Text="AllData" Value="AllData" 
>AllData</asp:ListItem>
           </asp:DropDownList>

如果要将数据重新绑定到行编辑事件中，则需要使用下拉选择值对其进行过滤

关于，

检查您是否在row_editing.nope上调用绑定数据方法。我重新绑定codebehind中的数据，无论从下拉过滤器中选择了两个选项中的哪一个，此过程都是相同的：private void BindGridViewData（）{var results=iidal.getUnauthorizedInvoices（ddlFilterDocs.SelectedValue）；GridView1.DataSource=results；GridView1.DataBind（）；}
