In my ASP.NET MVC application, I have metadata based model defined in database. I have a custom object defining the metadata of the data and uses dataset for DTO. To display this, I am planning to write a custom ModelMetadataProvider and ModelValidatorProvider.
Is this the right approach?
Any pointers on custom ModelMetadataProvider and ModelValidatorProvider?
The last day or so I was trying to figure out the same. It seems that writing a custom ModelMetadataProvider and ModelValidatorProvider is the way to go if you have metadata / validation configuration stored on database, some file or wherever.
I found this a great starting point.
Did you in the meantime already hacked together a solution? HTH,
Manu.
