Answer 1

I checked everything and finally got it,

I had to add to my web.config the following:

<configuration>
  <appSettings>
    <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
  </appSettings>
</configuration>

And that solved my issues

Answer 2

If you want to see a mark next to the field when validation fails, you should set the Text property of the validator:

<asp:RegularExpressionValidator ID="rev1" runat="server" ControlToValidate="TextBox1" Text="*" />

Also, if you want to see the error message, you must have a ValidationSummary in your form.
