title: ImageButton inside cell table doesn't work
body: <p>If I create <code>ImageButton</code> dynamically and add this into table cell</p>
  
  <pre><code>TableRow tr = new TableRow();
  TableCell tc = new TableCell();
  ImageButton imagebutton= new ImageButton();
  imagebutton.imageurl=imageurl;
  imagebutton.click+= new System.Web.UI.ImageClickEventHandler(click);
  tc.Controls.Add(imagebutton);
  tr.Controls.Add(tc);
  Table1.Rows.Add(tr);
  </code></pre>
  
  <p>The click event doesnt' work.</p>
  
  <p>However, if I use <code>Panel</code> instead of table the <code>imagebutton</code> works. Morevoer If I add imagebutton to the <code>page</code> directly it also works.
  But I need store <code>imagebutton</code> in a <code>table cell</code>.</p>
  
  <p>What is a problem? 
  How to make working <code>imagebutton</code> inside <code>asp table</code>?</p>
  
  <p>The method click is:</p>
  
  <pre><code>protected void click(object sender, EventArgs e)
  {
        Response.Write("&lt;script type='text/javascript'&gt;alert('OK!');&lt;/script&gt;"); 
  }
  </code></pre>
