单选按钮列表里面直放站OnSelectedIndexChanged不点火 [英] RadioButtonList Inside Repeater OnSelectedIndexChanged Not Firing

问题描述

我有一个中继器内的单选按钮列表。我的AutoPostBack设置为true，并定义的OnSelectedIndexChanged。当我在列表中选择一个不同的单选按钮的页面不回发，但我的定义OnSelectedIndexChanged事件不捕或射击。不知道我错过了什么。这是我的标记和codebehind：

I have a RadioButtonList inside a Repeater. I have AutoPostback set to "true" and the OnSelectedIndexChanged defined. When I selected a different radiobutton in my list the page does postback, but my defined OnSelectedIndexChanged event is not catching or firing. Not sure what I am missing. Here is my markup and codebehind:

推荐答案

使用中继器的ItemCreated事件到你的事件处理程序绑定：

Use the repeater's itemcreated event to bind your eventhandler:

 protected void Repeater!_ItemCreated(object sender, RepeaterItemEventArgs e)
        {
                if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
                {
                   e.item.FindControl("TaskRadioButtonList").SelectedIndexChanged += new EventHandler(TaskRadioButtonList_OnSelectedIndexChanged);

                }
        }
