问题描述
我有这样一个radiogruop。
I have a radiogruop like this.
<ext:RadioGroup ID="rdyIsAktifmi" runat="server" FieldLabel="Aktifmi" Width="150"
Flex="1">
<Items>
<ext:Radio ID="Radio4" runat="server" BoxLabel="pasif" InputValue="0" />
<ext:Radio ID="Radio5" runat="server" BoxLabel="aktif" InputValue="1" />
</Items>
</ext:RadioGroup>
我保存cheched输入值这个样子，
I save the cheched input value like this,
rdyIsAktifmi.CheckedItems[0].InputValue //0 or one depents on cheched item
不过从code结合它落后时我失败了。
however when binding it from code behind I failed.
我tryed这一个：
I tryed this one :
rdyIsAktifmi.CheckedItems[0].Values = employee_obj.IsAktif;(this come from database as integer value)
我也试过这样的：
I also tried this one :
rdyIsAktifmi.CheckedItems[0].Set("rdyIsAktifmi", employee_obj.IsAktif);
我怎么能在其inputValue将选择单选depents。
how I can select radiobutton depents on its InputValue.
**我正好在寻找一个methot这样的事情。
**what I exactly looking for a methot something like this.
rdyIsAktifmi.CheckedItem.InputValue = employee_obj.IsAktif;
rdyIsAktifmi.CheckedItem.InputValue=employee_obj.IsAktif;
感谢您。
推荐答案
我想实现这种方式。
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<%@ Import Namespace="System.Linq" %>
<script runat="server">
protected void Set0(object sender, DirectEventArgs e)
{
Radio r = this.RadioGroup1.Items.Cast<Radio>().First<Radio>(item => item.InputValue == "0");
r.Checked = true;
}
protected void Set1(object sender, DirectEventArgs e)
{
Radio r = this.RadioGroup1.Items.Cast<Radio>().First<Radio>(item => item.InputValue == "1");
r.Checked = true;
}
</script>
