  OnFocus function does not work

  Jun 01, 2012 08:57 AM|LINK

  <asp:HiddenField ID="hdnBlockRefresh" runat="server"/>
  
  <script type="text/javascript">
  function BlockGridRefresh() {
           document.getElementById('hdnBlockRefresh').Value = '0';
              alert(document.getElementById('hdnBlockRefresh').value);
          }
          function GridRefresh() {
              document.getElementById('hdnBlockRefresh').Value = '1';
          }
  </script>

  And 

  txtTechnician.Attributes.Add("onfocus", "BlockGridRefresh()");
  txtTechnician.Attributes.Add("onblur", "GridRefresh()");

  I have a griView with many textboxes with the same id and i want to set the hiddenField value when is no focus one of them.

  If a pun alert in BlockGridRefresh is displayed over and over again...and my hiddenField value is not set. Why this is happening?

  TY

  Hi,

  U have used .Value but javascript is case sensitive U need to use .value ( lowercase 'v').

  document.getElementById('hdnBlockRefresh').value = '0';

  and make sure the Id name is same as client ID

  :)

  Hi,

  I think until you submit the form, you can't access the Hidden field variable value!

  What you can do is, assign the value to a temp variable and access it!

  Hope it helps u...
