我看到奇怪的现象，从Ext.Net 2.0：RadioGroup.CheckedItems总是零在我改变处理程序回调。在下面RadioGroup1.CheckedItems我的code是始终为零检查后。我在做什么错了/我该如何解决此问题？

  [DirectMethod]
公共无效TxtVisibility（）
{
    的foreach（在RadioGroup1.CheckedItems VAR项）
    {
        如果（item.ID ==rdHourly）
        {
            txtPerHour.Hidden = FALSE;
            txtAtTime.Hidden = TRUE;
        }
        否则，如果（item.ID ==rdAtHourly）
        {
            txtPerHour.Hidden = TRUE;
            txtAtTime.Hidden = FALSE;
        }
    }
}
 

我的呼唤code：

 ＆LT;分机：RadioGroup中ID =RadioGroup1
                =服务器
                FieldLabel =
                ColumnsNumber =1＆GT;
    ＆LT;项目＆GT;
        ＆LT;分机：无线电台ID =rdHourlyFieldLabel =IsEveryPerHour
                   NAME =IsEveryPerHour=服务器
                   BoxLabel =每小时（S）填充=10＆GT;
        ＆LT; /分机：广播＆GT;
        ＆LT;分机：无线电台ID =rdAtHourlyFieldLabel =IsAtHour
                   NAME =IsAtHour=服务器
                   BoxLabel =在填充=10＆GT;
       ＆LT; /分机：广播＆GT;
    ＆LT; /项目＆GT;
    ＆LT;听众＆GT;
         ＆lt;改变处理程序=App.direct.TxtVisibility（）; ＆GT;＆LT; /更改＆GT;
    ＆LT; /听众＆GT;
＆LT; /分机：RadioGroup中＆GT;
 

解决方案

我只是回答了这个完全一样的问题上Ext.NET论坛，然后走了过来，堆栈，看看今天有什么新的...，发现了这个问题。

您可能需要等待下一个Ext.NET v2发行。您的示例似乎是工作的罚款与最新的源代码。有一个完整的工作示例在上面的链接。

I'm seeing strange behaviour from Ext.Net 2.0: RadioGroup.CheckedItems is always zero in my change handler callback. In my code below RadioGroup1.CheckedItems is ALWAYS zero after checking. What am I doing wrong / how can I solve this?

[DirectMethod]
public void TxtVisibility()
{
    foreach (var item in RadioGroup1.CheckedItems)
    {
        if (item.ID == "rdHourly")
        {
            txtPerHour.Hidden = false;
            txtAtTime.Hidden = true;
        }
        else if (item.ID == "rdAtHourly")
        {
            txtPerHour.Hidden = true;
            txtAtTime.Hidden = false;
        }
    }  
}

My calling code:

<ext:RadioGroup ID="RadioGroup1" 
                runat="server" 
                FieldLabel="" 
                ColumnsNumber="1">
    <Items>
        <ext:Radio ID="rdHourly" FieldLabel="IsEveryPerHour"
                   Name="IsEveryPerHour" runat="server"
                   BoxLabel="Per Hour(s)" Padding="10">
        </ext:Radio>
        <ext:Radio ID="rdAtHourly" FieldLabel="IsAtHour"
                   Name="IsAtHour" runat="server"
                   BoxLabel="At" Padding="10">
       </ext:Radio>
    </Items>
    <Listeners>
         <Change Handler="App.direct.TxtVisibility();" ></Change>
    </Listeners>
</ext:RadioGroup> 

I just answered this exact same question on the Ext.NET forums, then came over to Stack to see what's new today... and found this question.

You might need to wait for the next Ext.NET v2 release. Your sample appears to be working fine with the latest source. There's a complete working example at the link above.
