问题描述
我遇到一个奇怪的问题。我想看看有什么复选框被GridView控件中选择。我的code看起来像它遵循我在互联网上找到的例子，而在FF＆功放的工作原理; Chrome浏览器，但却未能在IE9。
在IE9中，选中属性永远返回true。我已经通过了code台阶状，已经验证了它在寻找正确的复选框，但IE浏览器将始终返回false。
有没有人有什么想法？下面是我的标记和放大器; codebehind。

对于每一行作为GridViewRow在gvParts.Rows

解决方案
确定，解决了。我的GridView不是我的表单标签内。我猜IE浏览器不喜欢这一点。
I'm running into a strange issue. I'm trying to see what checkboxes are selected within the gridview. My code looks like it follows the examples I found on the internet, and works in FF & Chrome, but fails in IE9. In IE9, the checked property never returns true. I've stepped through the code, and have verified that it's looking at the correct checkbox, but IE will always return false.
Does anyone have any ideas? Below is my markup & codebehind.
<asp:GridView ID="gvParts" runat="server"
AllowSorting="True" AutoGenerateColumns="False"
CellPadding="5" DataKeyNames="Rec_ID" DataSourceID="dsParts"
PageSize="50" Width="100%">
<Columns>
<asp:TemplateField HeaderText="Select">
<HeaderTemplate>
Select
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkSelect" runat="server"/>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" Width="75px" />
</asp:TemplateField>
<asp:BoundField DataField="Arcft_Make" HeaderText="Make"
SortExpression="Arcft_Make" >
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Arcft_Model" HeaderText="Model"
SortExpression="Arcft_Model" >
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Source_Name"
HeaderText="Source_Name"
SortExpression="Source_Name"
DataFormatString="{0:d}"
HtmlEncode="false">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Part_Number"
HeaderText="Part Number"
SortExpression="Part_Number" >
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Vendor_Part_Number"
HeaderText="Vendor Number"
SortExpression="Vendor_Part_Number" >
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Vendor_Name"
HeaderText="Vendor Name"
SortExpression="Vendor_Name" >
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Descr"
HeaderText="Description"
SortExpression="Descr">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle Width="300px" HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Date_Added"
HeaderText="Date_Added"
SortExpression="Date_Added">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="Rec_ID"
ReadOnly="True" Visible="False">
<ItemStyle Width="0px" />
</asp:BoundField>
<asp:CommandField ShowEditButton="True" />
</Columns>
<SelectedRowStyle BackColor="#FFFFCC" />
<AlternatingRowStyle BackColor="#CCFFFF" />
</asp:GridView>
`
And
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
解决方案
OK, solved. My gridview wasn't inside my form tags. I guess IE didn't like that.
