Repeater绑定用户控件事件

我有一个带有转发器的Web用户控件,在转发器内部我有一个动态数量的单选按钮,在page_load上我试图调用转发器的onDataItemBound事件来找到radiobuttons并将oncheckedchanged事件绑定到一个方法中我的代码,但不能让它工作,这是我的代码:

protected void Page_Load(object sender, EventArgs e)
{
    Repeater_Select.ItemDataBound += Repeater_Select_OnItemDataBound; 
}


protected void Repeater_Select_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        var customRbtn = (CustomRadioButton)e.Item.FindControl("RadioButton_Select");
        customRbtn.CheckedChanged += RadioButton_Select_OnCheckedChanged;
    }
}

我设法解决了我的问题,问题是我在此OnItemDataBound之前调用了另一个方法,它在转发器上调用DataBind(),所以我只是颠倒了顺序并放了在另一种方法之前调用OnItemDataBound,如下所示:

    protected void Page_Init(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            BindRadioOnChecked();
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            GetFeaturePackData();
        }
    }

    private void BindRadioOnChecked()
    {
        foreach (RepeaterItem item in Repeater_Select.Items)
        {
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                CustomRadioButton customRbtn = (CustomRadioButton)item.FindControl("RadioButton_Select");
                customRbtn.CheckedChanged += RadioButton_Select_OnCheckedChanged;
            }
        }
    }

现在它位于Page_Init内,因此在Page_Load

之前触发
