  1.   

    使用的方法就像这个样子public override void CreateView() {
            base.CreateView();
            this.gvwQuery.RowDblClick += new GridViewPlus.RowDblClickEventHandler(gvwQuery_RowDblClick);
            }    void gvwQuery_RowDblClick(object sender, int RowIndex) {
            JSHelper.Alert(MyHelper.ToString( this.gvwQuery.SelectedDataKey["ProductName1"]));
            this.BindDetailView();
            }

    GridView还有很多未知的有待于探索，Mark！
      

  4.   

     protected   void   GridView1_RowDataBound(object   sender,   GridViewRowEventArgs   e)
        { 
            if (e.Row.RowType == DataControlRowType.DataRow)

                {
                    e.Row.Attributes.Add("onclick", "yourfunction(" +i+ ");");
                    e.Row.Attributes.Add("id",""+i+"");
                    e.Row.Attributes.Add("ondblclick", "yourfunction2(" + i + ");");
                } 
            } 
        }

    这代码写的 
      

  5.   

    重写GRIDVIEW 实现 谢谢分享 
      

  6.   

    MyHelper
    这个是什么东西？
      

  7.   

    重写gridview 实现更好的复用啊  值得推荐！  
      

  8.   

    这让我想起当年有人写了个GridView72绝技！
      

  9.   

    MyHelper
    这个类是什么？怎么没人回答捏
      

  10.   

    学习，gridview还是有很多东西值得挖掘的
