Question

假设我们有Accordion控制，其中有几个按钮放在其他Accordion控件中。问题是这些按钮的事件不在服务器端处理。示例：

我有以下代码：

<form runat="server">
<ajax:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajax:ToolkitScriptManager>
<ajax:Accordion ID="Accordion1" runat="server" Enabled="True" Visible="true">
    <Panes>
        <ajax:AccordionPane ID="AccordionPane1" runat="server">
            <Header>
                header1 <asp:button id="ButtonH" runat="server" text="ButtonH" onclick="Button1_OnClick" />
            </Header>
            <Content>
                <ajax:Accordion ID="Accordion12" runat="server" Enabled="True">
                    <Panes>
                        <ajax:AccordionPane ID="AccordionPane12" runat="server">
                            <Header>
                                header2 
                                <asp:button id="ButtonH2" runat="server" text="ButtonH2" onclick="Button1_OnClick" />
                            </Header>
                            <Content>
                                <asp:button id="ButtonContent" runat="server" text="Content" onclick="Button1_OnClick" />
                                content1</Content>
                        </ajax:AccordionPane>
                    </Panes>
                </ajax:Accordion>
            </Content>
        </ajax:AccordionPane>
    </Panes>
</ajax:Accordion>
</form>

代码隐藏：

 protected void Button1_OnClick(object sender, EventArgs e)
 {
    var button = (Button)sender;
 }

Button1_OnClick方法仅在ButtonH点击时执行，但不在ButtonH2或ButtonContent次点击时执行。有没有人有我想念的想法？

谢谢！

感谢Tim Schmelter，我解决了这个问题。

Here is the forum post he referred to解释了需要完成的更改。我发现的摘要：

Accordion.cs类需要继承第46行的INamingContainer

public class Accordion : WebControl, INamingContainer`

如this related ASP.NET post

中所述

并且手风琴ItemCommand需要在第68行的事件处理程序中定义AccordionCommandEventArgs：

public event EventHandler<AccordionCommandEventArgs> ItemCommand;
//public event CommandEventHandler ItemCommand;

如this codeplex post

中所述

尝试设置SuppressHeaderPostbacks="false"。它对我有用。

事件不会从嵌套的Accordion控件触发
