onClick为动态生成的LinkButton

在我的sharepoint web部件应用程序中。我像下面这样动态地生成LinkButtons。这很好

foreach (var pName in productTypesNames[productType] )
{
   var subLi = new HtmlGenericControl("li");
   var linkButton = new LinkButton{ Text = pName };
   linkButton.Click += new EventHandler(linkButton_Click);
   subLi.Controls.Add(linkButton);
   ul.Controls.Add(subLi);
}

然而，当我点击UI中的一个链接时，我的调试器从来没有碰到在

void linkButton_Click(object sender, EventArgs e)
{
}

更多的代码

protected void StateClicked(object sender, CommandEventArgs e)
{
  //Generate a dictionary of type Dictionary<string, List<string>>
  //Display the dictionary
  foreach (var productType in productTypesNames.Keys)
        {
            var li = new HtmlGenericControl("li");
            nav.Controls.Add(li);
            var ul = new HtmlGenericControl("ul");
            var anchor = new HtmlGenericControl("a");
            anchor.Attributes.Add("href", "#");
            foreach (var pName in productTypesNames[productType] )
            {
                var subLi = new HtmlGenericControl("li");
                var linkButton = new LinkButton{ Text = pName };
                linkButton.Click += new EventHandler(linkButton_Click);
                subLi.Controls.Add(linkButton);
                ul.Controls.Add(subLi);
            }
            anchor.InnerHtml = productType;
            li.Controls.Add(anchor);
            li.Controls.Add(ul);
        }
 }
