I have a Save button working well. After I added an OnClientClick event to check s few required fields, I got error "Microsoft JScript runtime error: Object expected". I checked each field name in the javascript hanlder function, those reuired fields names are correct. I cannot figure out why it happens. Please help.

<asp:Button ID="btnSaveDev" runat="server" Text="Save" Width="120px" onclick="btnSaveDev_Click" OnClientClick="return (evalBeforeSave());"/>

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

       function evalBeforeSave()
       {  
            if (document.getElementById("<%=txtno.ClientID%>").value=="")
            {
                alert("Id # can not be blank");
                document.getElementById("<%=txtno.ClientID%>").focus();
                return false;
            }            
            if (document.getElementById("<%=txtcode.ClientID%>").value=="")
            {
                alert("Code can not be blank");
                document.getElementById("<%=txtcode.ClientID%>").focus();
                return false;
            }
            ...
           return true;
    }

</script>

Hello, where is declared the evalBeforeSave() function? is in the same aspx page? if not, you need to declare that function in the same page, so the control names can be dynamically rendered...  if yes, can you post the full rendered html code of your page?

Regards.

Thanks for the comment. I just found it because of a piece of previous code problem causing the error.

But your suggestion has a better coding style.
