Related Entities

Apr 9, 2010 at 5:40 PM

Hi,

I tried to do a similar control in the past, with Entity Framework.

The problem are always the foreign keys and related entities: in your sample, country is always another entity with a CountryId and a CountryName. And to be usefull, the control must let select the CountryName in your list, even it is come from another entity.

Do you have any plan to add this feature?

Hi Marcos

Glad to hear that the control of someone useful.


Sets of keys/fields is limited only by the developer-related entities which serves as input.

ie all related entities on the server side in ria services model to be displayed in the box to filter the data.

hi mtabaj. thought again about your words. do you mean the substitution of data from related tables into the field "Value"?

Hi bykinaq,

Thanks for following.  What I want is to be able to select all the customers who lives in Spain, even if in the customer table I have only the countryid.

What I want is to show CountryName in the fieldlist.

A typical case:  I use Guids for the IDs, so it's imposible to ask to write the Guid as a selection value.  I want to recover the related entities (Countries in this case), and add their properties to the fieldname list (or at list some of them, via some convention...)

I hope it is clear, don't hesitate to contact me.

Hi Sebastian.

Yes, you can help to this project.

You just need to look at:

Utilities.cs => Public Method GetListOfPropertyPathNames => Line 171

I take all of this code from SilverlightToolkit => DataForm
