关于隐藏列 指定的参数已超出有效值的范围的问题
各位大大，我想通过一个方法来指定隐藏列，但是运行的时候老是出错“指定的参数已超出有效值的范围”，请问各位大大问题出在哪里了呀，大概代码如下

HTML code

             <asp:GridView ID="GridView1" runat="server" AllowPaging="True"                  AutoGenerateColumns="False" DataKeyNames="id"   CssClass="Fontsmall"                 onpageindexchanging="GridView1_PageIndexChanging"                  onrowdatabound="GridView1_RowDataBound" Width = "100%"                  onrowcommand="GridView1_RowCommand"                  onrowcreated="GridView1_RowCreated"  >   <Columns> <asp:TemplateField HeaderText = "设备情况1" >                         <ItemTemplate>                        <asp:Image ID="Image1" runat="server"  ImageUrl ='<%# GetUrl( (string)Eval("qk1")) %>'/>                     </ItemTemplate>                </asp:TemplateField>                       <asp:TemplateField HeaderText = "设备情况2" >                         <ItemTemplate>                        <asp:Image ID="Image2" runat="server"  ImageUrl ='<%# GetUrl( (string)Eval("qk2")) %>'/>                     </ItemTemplate>                </asp:TemplateField>   </Columns></GridView>

后台代码

C# code

 protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)    {        e.Row.Cells[0].Visible = false;        e.Row.Cells[1].Visible = false;    }

[解决办法]
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[0].Visible = false;
e.Row.Cells[1].Visible = false;

}
添加个if条件 代码放里面
