Hello,

I have an issue with the WebMaskEditor control.  If I use this code on my ASPX page:

Zip:<ig:WebMaskEditor ID="mskZip" runat="server" CssClass="TextBox" InputMask="00000-0000" Width="90px" />
<asp:RegularExpressionValidator ID="zipValidator" 
                                runat="server" 
                                ErrorMessage="Invalid Zip Code"
                                ValidationExpression="(^(?!0{5})(\d{5})(-?)(?!0{4})((\d{4})||(_{4}))?$)" 
                                ControlToValidate="mskZip">*</asp:RegularExpressionValidator> 

I cannot get the validator and the WebMaskEditor to play well together.  The issue that I am having is the validation control will mark the mskZip value as invalid when the value is "55555-".
The regular expression I am using should allow "5555-".  As a matter of fact, it works great if I replace the WebMaskEditor with a regular ASP textbox.  So I guess the issue I am really having 
is that the RegularExpressionValidator doesn't work the same with the WebMaskEditor control as it does with an ASP textbox.  I thought the issue might be that the validation control was seeing
the underscores in the WebMaskEditor control so I modified the regular expression to account for those.  Testing it yielded the same results.  Again, if I replace the WebMaskEditor with a 
textbox it works as I would expect.

Here is what the code looks like whenever I replace the WebMaskEditor with a textbox:
Zip:<asp:TextBox ID="mskZip" runat="server" CssClass="TextBox" Width="90px" />
<asp:RegularExpressionValidator ID="zipValidator" 
                                runat="server" 
                                ErrorMessage="Invalid Zip Code"
                                ValidationExpression="(^(?!0{5})(\d{5})(-?)(?!0{4})((\d{4})||(_{4}))?$)" 
                                ControlToValidate="mskZip">*</asp:RegularExpressionValidator>

Any idea how I can work around this issue?
