我对 mediaroom 的 TVButton 控件有疑问。mediaroom 演示框架附带了一些事件和操作。如何在我的代码中为 tvbutton 调用我自己的事件处理程序。onButtonClick="btnlogin_ButtonClick" 不起作用。如果我为 void btnlogin_ButtonClick(object sender,EventArgs e){ } 编写自定义代码
onButtonClick 没有触发！mediaroom的示例代码！

<mrml:TVButton ID="TVButton1" runat="server" Style="position: absolute; top: 197px;

<mrml:TVActions ID="TVActions1" runat="server" Actions-Capacity="4">
<mrml:SubmitAction Gadgets="TVText1" Method="Get" Name="SubmitAction0" Target=""

</mrml:TVActions>
<mrml:TVLabel ID="TVLabel4" runat="server" Style="position: absolute; top: 137px;
left: 67px; height: 158px; width: 246px;" Text="Enter some text in TVText and click on TVButton to submit the TVpage. When the TVPage is submitted,
the control goes to the next page where you can see the text entered in the previous page.">
</mrml:TVLabel>
</mrml:TVPage>
</form>
所以这里我们只能给 OnClick="SubmitAction0"。上面的示例是源视图
