Hi,
I would like to be able to set which fields are available for datafiltering on the RadDataFilter. As i understand, this can be done using annotations. However i find the use of annotations cumbersome. I use the RadDataFilter to filter data in a RadGridView. The RadGridView is boud to a collection in the Viewmodel. Now in order to specify which fields are available for datafiletring, i would have to annotate the public fields of my viewmodel. I think this is a violation of seperation of View and Viewmodel. Moreover, if i have diferent views using the same viewmodel with a RadDataFilter and i wish to have different fields available for filtering in each view, then this cannot be done.
In my honest opnion, which fields can be filtered, and what their caption is in the RadDataFilter should be specified in a collection of the RadDataFilter itself (much as the columns collection in the RadGridView).
If you think i going the wrong way here please let me know.
Kind regards,
Ronald Steenbergen

Hello R,
This is absolutely possible.
You don't have to use annotations at all. You can set AutoGenerateItemPropertyDefinitions to false and then manually define the properties that you would like to show. This is done with through the ItemPropertyDefinitions collection. Each ItemPropertyDefinition has three properties:
- PropertyName
- PropertyType
- DisplayName
An online example can be seen here.
Let me know if there are problems.
Best wishes,

Hello. Is there a way to capture the event that auto-creates the definitions and cancel it if necessary? I'd like to autogenerate most but maybe there is 2 in the list of 10 that I don't want. Having to manually create the 8 I want is more work than just canceling the creation of the 2 I don't want.

Hi,

Unfortunately, there is no such event. You can mark your properties with data annotation attributes in case you do not want them auto-generated.
