Hello,

I use DNN 4.9, so i can only put UTD, no FNL. My question: Is it possible to create cascading DropDown lists in UTD?

For example, if I have UTD 1:

Country City
USA New York
USA Chicago
USA Houston
England London
England Manchester

 

and on UTD2 I have 2 fields (type: calculated i suppose):

When I choose 'Country' USA, to be ableto choose only New York, Chicago and Houston.

Maybe some combination of Reports module and UTD module?

If it's not possible with some kind of DataColumn.Expression expressions directly in the UTD, is it possible in some other way, using XSL?

If nothing is possible up to here, can you give some direction using MS SQL commands / procedures or VB.NET programming? Which files to edit, where?

Sorry, it is neither possible with UDT nor with FnL.

While there is a chance to add such a feature as a new datatype with some codding efforts without touching the FnL source at all, UDT is not designed for extensions. Please remember that UDT is still a DNN3.x  module based on Asp.Net 1.1. While it is not impossible, I cannot recommend that you go that way.

Hi,

This is quite a common feature of many sites. Can you suggest something to start from at least...

Best Regards,

Dimitar
