asp.net - 使用 IE 的 Gridview 中的复选框

Question

我遇到了一个奇怪的问题。我正在尝试查看在 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示例，在 FF 和 Chrome 中工作，但在 IE9 中失败。在 IE9 中，checked 属性永远不会返回 true。我已经单步执行了代码，并验证了它正在查看正确的复选框，但 IE 将始终返回 false。

有没有人有任何想法？下面是我的标记和代码隐藏。

                         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

好的，解决了。我的 gridview 不在我的表单标签内。我猜IE不喜欢那样。
