If you want to allow any type of pattern as you mentioned as long as the string contains just numbers and dashes, you could use :

^[\d-]+$

or (you can explicitly escape the dash as well using \-):

^[\d-]+$

which would be used in a RegularExpressionValidator as such :

ASP.NET

<asp:regularexpressionvalidator id="YourValidator" runat="server" xmlns:asp="#unknown">
                                Display="Dynamic" 
                                ControlToValidate="Txt_ID" 
                                ValidationExpression="^[\d\-]+$" 
                                ErrorMessage="ID# - 15 Characeter Length.">
</asp:regularexpressionvalidator>

Explanation of Expression

^ # Beginning of expression
[\d-]+ # Allows one or more (+) digits (\d) or dashes (-)
$ # End of expression
Additionally, if you wanted to specify the format such as the one that your example shows, you would use :

^\d{3}-\d{3}-\d{3}$
