动态创建链接按钮列表,链接按钮不回发

Question

嗨,我在'ul li'列表中动态创建链接按钮.然后我尝试将每个链接按钮绑定到单击事件,其中我将标签设置为单击链接按钮的文本.然而应该开火的事件不会被解雇？

    if (!Page.IsPostBack)
        {
int listItemIds = 0;
       foreach (Node productcolour in product.Children)
       {
           HtmlGenericControl li = new HtmlGenericControl("li");
           LinkButton lnk = new LinkButton();
           lnk.ID = "lnk" + listItemIds;
           lnk.Text = productcolour.Name;
           lnk.Click += new EventHandler(Clicked);
           //lnk.Command += new CommandEventHandler(lnkColourAlternative_Click);
           //lnk.Click 
           li.Controls.Add(lnk);
           ul1.Controls.Add(li);
           listItemIds++;
       }
}

以上内容包含在if(!page.ispostback)中,标签文本永远不会在其他地方设置.继承人

protected void Clicked(object sender, EventArgs e)
{
    LinkButton lno = sender as LinkButton;
    litSelectedColour.Text = lno.Text;

}

代码必须在每个回发上运行:

    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);

        int listItemIds = 1;

        for (int i = 0; i < 10; i++)
        {
            var li = new HtmlGenericControl("li");
            var lnk = new LinkButton();

            lnk.ID = "lnk" + listItemIds;
            lnk.Text = "text" + i;
            lnk.Click += Clicked;
            //lnk.Command += new CommandEventHandler(lnkColourAlternative_Click);
            //lnk.Click 
            li.Controls.Add(lnk);
            ul1.Controls.Add(li);
            listItemIds++;
        }
    }

    private void Clicked(object sender, EventArgs e)
    {
        var btn = sender as LinkButton;
        btn.Text = "Clicked";
    }
