Dynamic list on form

[Joe]

Is it possible to have a dynamic list of fields?  Having to pre-define the model that the fields are built on dopes not work for our use cases

Hi Joe,

If you do not know the schema of the model ahead of time and cannot put attributes on properties in a class, you can define your own custom PropertyMetaDataProvider implementation. This will let you programmatically determine the type and define the metadata depending on that type. 


Docs and Demo

Please follow the tutorial in the Third Party Data Source section in the DataForm's Data Source documentation. You can also review the accompanying demo source code here on GitHub.


Further Assistance

If you have trouble wiring up your custom PropertyMetaDataProvider, please open a new ticket to request custom metadata design and attach a small demo with an example of your code/data. I know this may be an inconvenience, it's the fastest way to get you a solution due to the fundamental custom nature of this scenario (i.e. we need to see the dynamic data directly to help).
