You can have more than one validator control to validate a single textbox you simply add both validator controls and set the ControlToValidate attribute on both validator controls to the textbox id.

Do I need to use "Display = "Dynamic"?  I want the message to display either message.

*invalid $ amount or *Required field

The Display attribute determines whether the validation controls have space allocated on the page for them or they are added to the page when the failure occurs.

Generally you would set Display= Dynamic so that you don't have empty space on the page.

I tried below. It still postback when txtprice is empty. It does display "*required" though.

<asp:TextBox ID="txtprice" runat="server"></asp:TextBox><asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtprice" ErrorMessage="Incorrect Amount" ValidationExpression="^-?([1-9]\d*|(\d+))(\.\d{2})$" ValidationGroup="Group_price" Display="Dynamic"></asp:RegularExpressionValidator><asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ControlToValidate="txtprice" ErrorMessage="*Required" ValidationGroup="Group_price" Display="Dynamic"></asp:RequiredFieldValidator>

Have you set the ValidationGroup property for the submit button?

Also check if there are any other javascript errors on the page using Firebug plugin for Firefox. If there are any javascript errors on the page, then the page will postback.

Wow. Looks like I should have shown you an example instead of asking you a question. Very good. It's a lesson for me. Thanks @VBdotnet2005
