>>As I mentioned in my other reply the validation is being performed on the server side for browsers other than IE, again that is by design.

You're right no Javascript is being sent to the browser. Actually, I like calling the Validate() methods directly and testing ISvalid property better anyway.

>>As for the layout rendering differences between browsers, your best bet is to drop the grid layout and switch to flowLayout mode. If you intend to target browsers other than IE then this is the only way to go. For gridLayout to work in older browsers such as Netscape 4.x you have to change the targetSchema and the results are typically just as bad.

I think I'll stick with HTML 3.2 for downlevel browsers and save myself some headaches

>>As you are seeing there are other problems such as setting control widths that still have to be addressed. You can fix these by applying the required attributes from code. For example to size a textbox control that will hold in Netscape add the size attribute.

you can also do this:

<style>.w60{width=60px}.w70{width=70px}</style>
<form ....
<asp:textbox id="TextBox1"  runat="server" cssstyle=w60>
<asp:textbox id="TextBox2"  runat="server" cssstyle=w60>
<asp:textbox id="TextBox3"  runat="server" cssstyle=w70>
