ASP.NET - Textbox text change event

Hi

I am having textboxes in the grid,when i change any text in the textbox in the textchanged event i need both my OLD and NEW values i tried with javascript onfocus setting the textbox value to the hiddenfield but if click tab in current textbox  next textbox onfocus is firing before the current textchange event.

Please help

Hi,

use the onfocus and onblur events in combination

<script language="javascript" type="text/javascript">
      function printvalues() {
      alert('old value -' + document.getElementById('Hidden1').value );
      alert('new value -' + document.getElementById('Textbox1').value);
      }
    </script>

<asp:TextBox runat="server" ID="Textbox1" onfocus="document.getElementById('Hidden1').value=this.value;" onblur="printvalues();"  Text="Old"></asp:TextBox>
