c# – 从页脚调用命令时获取转发器项复选框值

<asp:Repeater ID="rptItemList" runat="server">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
    <div>
        <asp:CheckBox ID="chkItem" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"ItemName").ToString() %>' />
        <asp:HiddenField ID="hdItem" runat="server" Value='<%# DataBinder.Eval(Container.DataItem,"ItemId").ToString() %>' />
    </div>
</ItemTemplate>
<FooterTemplate>
    <asp:LinkButton ID="lbtnDel" runat="server" Text="Delete" OnClick="lbtnDel_Click" OnClientClick="return confirm('Are you sure you want to delete selected items from this list?')"></asp:LinkButton>
</FooterTemplate>
</asp:Repeater>

并按照后面的代码来处理lbtnDel_Click事件：

protected void lbtnDel_Click(object sender,EventArgs e)
    {
        foreach (RepeaterItem ri in rptItemList.Items)
        {
            CheckBox chk = (CheckBox)ri.FindControl("chkItem");
            HiddenField hd = (HiddenField)ri.FindControl("hdItem");

            if (chk.Checked)
            {
                var tc = new ItemController();
                tc.DeleteItem(Convert.ToInt32(hd.Value));
            }
        }
        Response.Redirect(DotNetNuke.Common.Globals.NavigateURL());
    }

当我选中一个复选框并单击“删除”时,代码会找到该复选框,但会将其读取为未选中状态,因此不会删除该项目.

有任何想法吗？
