title: Issue related to inbuilt javascript function of Telerik controls
body: <p>I have asp.net webapplication having some telerik controls.</p>
  
  <p>i have a RadTextBox(txtSearch) and RadButton(btnSearch) on .aspx page.</p>
  
  <p>i have written following validation for empty Textbox:</p>
  
  <pre><code> $('#btnSearch').click(function () {
                  if ($('#txtSearch_text').val() == '') {
                      $('#txtSearch_text').addClass('validation');
                      return false;
                  }
                  else {
                      $('#txtSearch_text').removeClass('validation');
                  }
              });
  </code></pre>
  
  <p>in <code>validation</code> class i have set <code>Border-left:2px solid red</code> 
  now problem is that  when i click on <code>btnSearch</code> it sets validation class to <code>txtSearch</code>  textbox, but when i use mouseover on txtSearch textbox class name suddenly changed to someother from inbuilt javascript function of Telerik. in this Javascript function of telerik TextBox, it changes class name of textbox to another class.
  and this execution of change class occurs after executing custom javascript function.</p>
  
  <p>so i want to execute customer javascript function  after executing inbuilt functions of telerik. how to do it?</p>
  
  <p>Thanks</p>
