I came across a bug with Google chrome ver 1.0.154.43 while answering a problem in asp.net forums.

Problem:

Chrome browser ignores "onblur" event function for input box while it has Required field validator attached to it . Check this code..

  <input id="txt1" runat="server" type="text" maxlength="16" style="width: 127px" onblur= "formatSSN();"/>

  <asp:RequiredFieldValidator ID="Rfssn" runat="server" ControlToValidate="txt1" Display="None" ErrorMessage="SSN" 

     SetFocusOnError="True" EnableViewState="False">

  </asp:RequiredFieldValidator>

  <script language="javascript" type="text/javascript">

   function formatSSN() 

  {

    var ssn = document.getElementById("txt1").value;

    if(ssn.length == 9) 

        {

            document.getElementById("txt1").value= ssn.substring(0, 3) +"-" + ssn.substring(3, 5) + "-" + ssn.substring(5, 9); 

            return false;

        }

  }

  </script> 

The code works fine in IE6/7 & FireFox3, but not in Google chrome .

Solution:

I think the problem is with required field validator's SetFocusOnError property. Setting SetFocusOnError="false" for Rfv will fix it in chrome.
