几个小技巧

也许对于某些人来说，有些过时，不过对新手，还是有用的

1 gridview中RadioButtonList的SelectedIndexChanged事件绑定

 protected void grid_RowCreated(object sender, GridViewRowEventArgs e)
        {
              if (e.Row.RowIndex != -1)//当row为头的时候不运行以下代码
              {                   RadioButtonList rblName = e.Row.Cells[7].FindControl("rbl") as RadioButtonList;
                rblAreaName.SelectedIndexChanged += new EventHandler(rblName_SelectedIndexChanged);
                }
        }

2SelectedIndexChanged事件触发后，如何获得是哪一行的RadioButtonList触发了这个事件

 void rblAreaName_SelectedIndexChanged(object sender, EventArgs e)
        {
            RadioButtonList rblName = sender as RadioButtonList;//将触发事件的对象，转化成对应的控件
            GridViewRow row = rblName.Parent.Parent as GridViewRow;//获得该控件在gridview上的行
                                
        }

3 gridview中ItemTemplate的另类用法

<ItemTemplate>
                                                                 a:  <asp:Label ID="Label1" runat="server" Text='<%# Bind("a")%>'></asp:Label>
                                                                 <br />
                                                                b:  <asp:Label ID="Label2" runat="server" Text='<%# Bind("b")%>'></asp:Label>
                                                                                                                          </ItemTemplate>
