  Hello this piece of  code has a problem that the click events don't fire:

  void Page_Load(...)
  {
     LoadFiles();
  }
  
  
  

  void LoadFiles()
  {
  DataTable td = GetTable();
  for(int i=0;i<td.Rows.Count;i++)
  {
  //Some Code here
  //
  LinkButton butt = new LinkButton();
  butt.CommandName = td.Rows[i]["id"].ToString();
  butt.Text = "Edit";
  butt.Click += new EventHandler(butt_edit);
  panel1.Controls.Add(butt);
  }
  
  
  
  
  
  
  
  
  
  
  
  

  void butt_edit(....)
  {
    LinkButton lb = (LinkButton)sender;
  
  

  int id = int.Parse(lb.CommandName);
  LoadEdit(id);
  }
  }
  
  
  

   

  It should call the LoadEdit method when the linkbutton edit is clicked but the event doesnt fire

  So please help

  dynamically added controls need to be recreated on page_load or int every time for their events to be persisted.

  Regards

  Button are already created on Page_Load as LoadFiles() method which create the buttons is basically called on page load, the problem is that events dont fire

  The event will not be fired of course because every time you click the

  linkbutton, the page loaded and then call LoadFiles( ) again and you click the

  linkbutton and the page loaded again and call LoadFiles( ) ... and so on..

  So,by this way.. the event will never be fired ..

  Try to find a  way to call the Butt_edit () in the page load ..

  I'm ready to help you If you need any help,,

  what you can do is.. try to check if the page is posting back or is it newly created.

  if ( !Page.IsPostBack )
  {
       LoadFiles( );
  }
  
  
  

  I did something similar here http://www.developerfusion.co.uk/forums/thread/148306/
