Telerik RadGrid排序ASP.NET C＃

无论我放入什么代码，我的Telerik RadGrid都不会排序。我尝试了很多东西，每次点击标题时，箭头和颜色都会改变，但数据将保持相同的顺序。这是我最新的代码块。（我从Telerik网站得到这个）请告诉我我在这里做错了什么。Telerik RadGrid排序ASP.NET C＃

<telerik:RadGrid runat="server" ID="radProductsGrid" Skin="Default" AllowSorting="true" 
AllowPaging="true" OnSortCommand="radProductsGrid_SortCommand" 
OnNeedDataSource="radProductsGrid_NeedDataSource" AutoGenerateColumns= "false" 
GridLines="None" ShowGroupPanel="false" PageSize="100"> 
<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ItemNumber" DataField="ItemNumber" HeaderText="Item Number" UniqueName="ItemNumber"> 
</telerik:GridBoundColumn>  
<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ProductName" DataField="ProductName" HeaderText="Product Name" UniqueName="ProductName"> 
</telerik:GridBoundColumn> 
<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="CategoryName" DataField="CategoryName" HeaderText="Category Name" UniqueName="CategoryName"> 
</telerik:GridBoundColumn> 

protected void radProductsGrid_SortCommand(object sender, GridSortCommandEventArgs e) 
    { 
     GridTableView tableView = e.Item.OwnerTableView; 
     if (e.SortExpression == "ItemNumber") 
     { 
      e.Canceled = true; 
      GridSortExpression expression = new GridSortExpression(); 
      expression.FieldName = "ItemNumber"; 
      if (tableView.SortExpressions.Count == 0 || tableView.SortExpressions[0].FieldName != "ItemNumber") 
      { 
       expression.SortOrder = GridSortOrder.Descending; 
      } 
      else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Descending) 
      { 
       expression.SortOrder = GridSortOrder.Ascending; 
      } 
      else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending) 
      { 
       expression.SortOrder = GridSortOrder.None; 
      } 
      tableView.SortExpressions.AddSortExpression(expression); 
      tableView.Rebind(); 
     } 
    }

而不是做这个的：

tableView.SortExpressions.AddSortExpression(expression); 
tableView.Rebind();

这样做：

radProductsGrid.MasterTableView.SortExpressions.AddSortExpression(expression); 
radProductsGrid.Rebind();

你能为你的答案添加一个解释吗？ –

检查的JavaScript的onclick（）事件，其排序丢弃事件

  var hasChanges, inputs, dropdowns, editedRow; 

      function RowClick(sender, eventArgs) { 
       if (editedRow && hasChanges) { 
        hasChanges = false; 
        if (confirm("Update changes?")) { 

         $find("<%= RadGrid1.ClientID %>").get_masterTableView().updateItem(editedRow); 
        } 
       } 
      }
