asp.net gridview索引错误

Question

我有一个工作正常的gridview。 它有一些隐藏的列，然后是可见的列。 当我单击每一行时，后面的VB代码从所选行中的每个列值获取值，并将值放在gridview下面的单独文本框中，例如

txtProjectId.Text = GridView1.SelectedRow.Cells(2).Text.ToString ' project ID

一切正常。

根据要求查找以下gridview代码（缩短版）。

         <div id="div_GRIDVIEW" class="div_Gridview" clientidmode="Static"  runat="server" >

            <asp:GridView ID="GridView1" Width="1370px"  runat="server" AllowPaging="True" AllowSorting="True"  OnSelectedIndexChanged = "OnSelectedIndexChanged"  OnRowDataBound = "OnRowDataBound"

                          </Columns>


        </asp:GridView>

        </div>

以下是选择行时代码的一部分......会话中出现索引错误（＆＃34; txtcurrentID＆＃34;）= GridView1.SelectedRow.Cells（1）.Text.ToString：

 Protected Sub OnSelectedIndexChanged(sender As Object, e As EventArgs) 'Handles gridview1.SelectedIndexChanged 



        Session("txtcurrentID") = GridView1.SelectedRow.Cells(1).Text.ToString 
        Session("txtcurrentPDID") = gridView1.SelectedRow.Cells(2).Text.ToString 
        Session("PCF") = GridView1.SelectedRow.Cells(3).Text.ToString
        Session("OCF") = GridView1.SelectedRow.Cells(4).Text.ToString
        Session("OFF") = GridView1.SelectedRow.Cells(5).Text.ToString
        Session("DCF") = GridView1.SelectedRow.Cells(6).Text.ToString
        Session("OnCF") = GridView1.SelectedRow.Cells(7).Text.ToString
end sub 

所以现在当我点击每一行时，我收到以下错误：

指数超出范围。必须是非负数且小于集合的大小。

一切正常，gridview正确显示，标题过滤器看起来很棒。 但是我不能再单击/选择每一行...... 任何想法??
