事件里面没有的ListView射击单选按钮列表 [英] Event not firing on RadioButtonList inside ListView

问题描述

我附上的ListView SlectedIndexChanged事件与RadioButtoList OnSelectedIndexChanged事件（也就是里面的ListView），当我运行该程序，点击单选按钮，也没有事件火连我实现了所有code为这个特定的事件触发。然而，有没有语法或编译错误。告诉我，我叫什么类型的事件，这对无论是ListView控件或单选按钮列表？

的.aspx code：

 ＆LT; ASP：ListView控件ID =ListView1的=服务器＆GT;
＆LT;＆ItemTemplate中GT;
    ＆LT; ASP：RadioButtonList的ID =radiobuttonlist4=服务器的AutoPostBack =真RepeatDirection =水平WIDTH =240像素onselectedindexchanged =选择＆GT;
        ＆LT; ASP：ListItem的值=同意＆GT;＆LT; / ASP：ListItem的＆GT;
        ＆LT; ASP：ListItem的值=不同意＆GT;＆LT; / ASP：ListItem的＆GT;
        ＆LT; ASP：ListItem的值=strongagree＆GT;＆LT; / ASP：ListItem的＆GT;
        ＆LT; ASP：ListItem的值=strongdisagree＆GT;＆LT; / ASP：ListItem的＆GT;
    ＆LT; / ASP：RadioButtonList的＆GT;
＆LT; / ItemTemplate中＆GT;
＆LT; /列表视图＆GT;
 

code背后：

 保护无效的选择（对象发件人，EventArgs的发送）
{
    单选按钮列表listtt =（单选按钮列表）发送;
    ListViewItem的项目=（ListViewItem的）listtt.NamingContainer;    单选按钮列表ER =（单选按钮列表）item.FindControl（radiobuttonlist4）;
    er.SelectedIndexChanged + =新的EventHandler（处理）;
}公共无效手柄（对象发件人，EventArgs的发送）
{
    Label3.Text =hjeje;
}
 

解决方案

在 ListView控件的 的ItemDataBound 方法

，你需要在选事件有约束力。

  VAR RDO = e.Row.FindControl（radiobuttonlist4）作为单选按钮;
rdo.OnSelectedIndexChanged + =新的EventHandler（选择）;
 

I attach OnSelectedIndexChanged event with RadioButtoList (that is inside ListView)in SlectedIndexChanged event of listview , when I run the program, click on RadioButton, there no event fire even I implemented all code for this particular event firing. However there is no syntax or compilation error. Tell me what type of event I call against which either ListView or RadioButtonList?

.aspx Code:

<asp:ListView ID="ListView1" runat="server"  >
<itemtemplate>
    <asp:RadioButtonList ID="radiobuttonlist4" runat="server" AutoPostBack="true" RepeatDirection="Horizontal" Width="240px"  onselectedindexchanged="selected">
        <asp:ListItem Value="agree" ></asp:ListItem>
        <asp:ListItem Value="disagree"></asp:ListItem>
        <asp:ListItem Value="strongagree"></asp:ListItem>
        <asp:ListItem Value="strongdisagree"></asp:ListItem>
    </asp:RadioButtonList>
</itemtemplate>
</listview>

Code Behind:

protected void selected(object sender, EventArgs e)
{    
    RadioButtonList listtt = (RadioButtonList)sender;       
    ListViewItem item = (ListViewItem)listtt.NamingContainer;

    RadioButtonList er = (RadioButtonList)item.FindControl("radiobuttonlist4");    
    er.SelectedIndexChanged += new EventHandler(handle);                    
}

public void handle(object sender, EventArgs e)
{            
    Label3.Text = "hjeje";        
} 

解决方案

in your ListView's ItemDataBound method, you need to bind the selected event there.

var rdo = e.Row.FindControl("radiobuttonlist4") as RadioButton;
rdo.OnSelectedIndexChanged+= new EventHandler(selected);
