How do I get my ASP.NET page to retain the value when I select another dropdown control
Posted on 2015-02-23
I have a small problem that is turning into a headache. I have a requirement whereby I need to have a dynamic input mask that is set based upon what has been selected prior. This part is done - I've achieved this through making use of the AjaxMaskedEdit control and retrieving the values from my SQL Server database.
When I type into the box I can see my delimiter such as "-" or a "/". The problem occurs when I select another dropdown control and change its value and when the page reloads 123-456 becomes 123456 and I need it to retain the "-". I've seen a few examples where a session may be the best way to go about it but I have had no such luck getting it to work as yet.
I suppose my question in a nutshell is how can I store the value after the focus is shifted from the control that I have given the masked input?
