Kindly give me a solution.

<script type="text/javascript">
     function Validate() {
         var lblEmp = document.getElementById('<%= lblEmp.ClientID %>');
         if (Condition){
              lblEmp.style.display = 'block';
              return false;
         }
         else{
             lblEmp.style.display = 'none';
             return true;
         }
    }
</script>

<asp:Button ID="btnSave" runat="server" Width="100px" CssClass="button"
      Text="Save" OnClick="btnSave_Click" OnClientClick="return Validate();" />

Thanks & Regards,

Katte
