  1.   

    可以在绑定数据到 DataGrid 的时候用for(int i=0;i<this.dg_NewsImage.Items.Count;i++)
    {
    this.dg_NewsImage.Items[i].Cells[2].Attributes.Add("onclick","return confirm('确定删除该记录？')");
    }
      

  2.   

    btnDelete.Attributes.Add("onclick","return confirm('确定删除？')");
      

  3.   

    给你个实例:

      if(confirm('确定删除该记录？')){
        __doPostBack('按钮ID','');
      }
    }
    </script><asp:Button id="" runat="server" href="javascript:click();"></asp:Button>
