Thanks for teh reply dear.

I solved it.

I've created one javascript fuction which checks the values of the textboxes and i linked this function to the OnClientClick attribute of the update button.

<asp:Button ID="btnxxxxxx" runat="server" Text="Update" OnClick="btnxxxx_OnClick" CausesValidation="false" OnClientClick="javascript:Checkbeforeupdate()"/>

and the javascript function is 

function Checkbeforeupdate() 
    {
      var organizeremialid=document.getElementById('ctl00_BodyContent_xxxxxxxx');
      var presenteremialid=document.getElementById('ctl00_BodyContent_xxxxxxxx');
      
      if(organizeremialid.value=="" || presenteremialid.value=="")
      {
       alert('Please enter the organizer and presenters EmailIDs');
      }
    
    }

Its working fine.

Thank you..
