i do have a user grid of which one of the columns show up the ssn numbers of the users in the grid. i want to achieve some sort of formating similar to currency but for the ssn numbers.

Lets assume i just have a grid with only 2 columns of which one of them shows up the name and other shows up the ssn

i tried the following with no luck. 

-

<ISWebGrid:WebGridColumn Caption="SSN" DataMember="ssn" Name="cur" 

                        Width="150px" DataFormatString="000-00-0000">

                    </ISWebGrid:WebGridColumn>

Can someone explain is this something achievable, if yes whats the right way of getting this work. Any help is really appreciated.
