使用IE的Gridview复选框

我遇到了一个奇怪的问题。我试图看看在gridview中选择了哪些复选框。我的代码看起来像我在互联网上找到的例子，并且在Chrome中运行FF &，但在IE9中失败。在IE9中，checked属性从不返回true。我已经浏览了代码，并验证了它正在查看正确的复选框，但IE始终会返回false。使用IE的Gridview复选框

有没有人有任何想法？以下是我的标记&代码隐藏。

<asp:GridView ID="gvParts" runat="server"

     </Columns> 
     <SelectedRowStyle BackColor="#FFFFCC" /> 
     <AlternatingRowStyle BackColor="#CCFFFF" /> 
    </asp:GridView>

而且

Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) 
         Handles btnAdd.Click 
    Dim Rec_IDs As New List(Of String) 
    Dim Rec_ID As Int32 
    Rec_IDs = Session("Rec_IDs") 
    For Each Row As GridViewRow In gvParts.Rows 
     If CType(Row.FindControl("chkSelect"), CheckBox).Checked Then 
      Rec_ID = gvParts.DataKeys(Row.RowIndex).Value 
      If Not Rec_IDs.Contains(Rec_ID) Then 
       Rec_IDs.Add(Rec_ID) 
      End If 
      CType(Row.FindControl("chkSelect"), CheckBox).Checked = False 
     End If 
    Next 
    Session("Rec_IDs") = Rec_IDs 
    lblCount.Text = String.Format("You have {0} records selected", 
            Rec_IDs.Count.ToString) 
End Sub

@Chris，感谢您清理代码。如果你告诉我它是如何完成的，下次我会确保自己做。 –

OK，解决。我的gridview不在我的表单标签内。我想IE不喜欢那样。
