title: TextBox in the RadGrid control doesn't make partial postback and fills the other controls
body: <p>I have a <code>TextBox</code> (named as txt_lect_in) in <a href="http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultcs.aspx#qsf-demo-source" rel="nofollow">RadGrid</a> and I handled the <code>TextBox</code> changed event so it fills other textboxes (<code>gv_txt_name,gv_txt_mobile,gv_txt_address,gv_txt_email</code>) in the same grid.</p>
  
  <hr>
  
  <p><strong>The problem is:</strong>
  The <code>TextBox</code> (<code>txt_lect_in</code>) doesn't fills the other textboxes, I know the reason but I don't know how to fix it.</p>
  
  <p>After I remove the <a href="http://demos.telerik.com/aspnet-ajax/ajax/examples/overview/defaultcs.aspx" rel="nofollow">RadAjaxManager</a>, it fills the other textboxes in the grid but it does full post back, how to keep the ajax manager and fill the controls at the same time?</p>
