I have this textBox control <asp:TextBox ID="txtInformerPhone" runat="server" />
This input is a telephone number and has the following restrictions.
A valid phone number must have the following requirements. First part of the phone number is either 2 figures or 3 figures or 4 figures. The second part is
either 5 figures or 6 figures or 7 figures or 8 figures or 9 figures.
So the user can enter for example 123-12345
This is valid because the first part containd 3 figures which is valid the second part contains 5 figures which is also valid.
Note the user must also enter this character - that is located between the first part and the second part.
I just wonder is it possible to use MaskedEditExtender for this testBox when I have this requirements
