如何覆蓋GridView的OnItemDataBound方法？

Question

我想製作服裝Gridview。我覺得很不錯的開源之一，但問題是，它使用DataGrid當我更改繼承類GridView，我得到以下錯誤

AADGridView.OnItemDataBound（DataGridItemEventArgs E）：沒有合適的方法找到覆蓋

我倍率在此：

//public class AADGridView : DataGrid, IPostBackEventHandler 
     public class AADGridView : GridView, IPostBackEventHandler 
     { 

      /// <summary> 
      /// Gets or sets a value that indicates whether the auto filter is displayed in the AADGrid.AADGridControl. 
      /// </summary> 
      [Bindable(true), Category("Appearance"), Description("Whether to show the control's auto filter."), DefaultValue(true),] 


      /// <summary> 
      /// Override the DataGrid constructor. 
      /// </summary> 
      public AADGridView() : base() 
      { 
       // create the ArrayList to contain the DropDownList controls and the SortedList objects added to the header items; 
       //list = new ArrayList(); 
       sort = new ArrayList(); 
       filter = true; 
      } 

      /// <summary> 
      /// Override the OnItemDataBound event. 
      /// </summary> 
      /// <param name="e"></param> 
      override protected void OnItemDataBound(DataGridItemEventArgs e) 
      { 
       //Some Code 
       base.OnItemDataBound(e); 
      } 

，你在代碼中看到的，我舉st改爲DataGrid至GridView。他們都有OnItemDataBound，那麼問題是什麼？ 謝謝

事件參數的類型爲DataGridItemEventArgs。您必須將參數類型更改爲新的基類的參數。
