利用delegate调用userControl的方法

 

1, 在UserControl里定义delegate
    public delegate void SearchHandle(object sender, EventArgs e);
    public event SearchHandle SearchEvent;
    protected void btnSearch_ServerClick(object sender, System.EventArgs e)
   {
       if(SearchEvent != null)
       {
          SearchEvent(sender,e);
       }
  }
2, 在使用UserControl的form里头设置并调用
    protected ArtArchives.Web.WebControls.SearchBar Search;
    Search.SearchEvent += new ArtArchives.Web.WebControls.SearchBar.SearchHandle(Search_SearchEvent);
    private void Search_SearchEvent(object sender, EventArgs e)
   {
   }
