Validation Input for the UI

How do you validate the controls on the page? Specially, when checking for required fields. Let's say you have 10 textboxes and they are all required would you use a requiredfieldvalidator control for each of the textboxes.
<asp:TextBox id="txtName" runat="server" />

<asp:RequiredFieldValidator id="rfvName" runat="server" ControlToValidate="txtName" ErrorMessage = "!" />
Refactor it!

I generally create a TextField control that contains: * Label * Textbox * Validator(s) and then just use properties to control how/if they are displayed. so in your case, you could have 10 TextField controls that look like this:

<my:TextField id="txtName" runat="server" Label="Name" Required="true" />
<my:TextField id="txtPhone" runat="server" Label="Phone #" Required="true" ValidateNumeric="true" />

I also think that a multi required field validator control would be a good idea. Simply, insert the textbox id and the message to be displayed and the control will take care of the rest.

I would usually name my textboxes sequentially such as "txtRequired1, txtRequired2" then do a loop. This is when I use a custom validator. Just my 2 cents but it's good to know the other methods out there as far as validation.
