Filter Sets
Defines a set of predefined entity filters that can be selected when loading data from a DataService.
When more than 1 filter is defined in the filter set, all the search criteria must be satisfied, before the correct record is loaded (i.e. there is AND between the filters).
Child Elements
- Filter Set Filter - Maps an entity filter to a filter set.
Example
Let’s say you have a data structure called Invoice. By loading this data structure without a filter, you would get all the invoices ever entered to the system. So at least you will need a filter, which will load just one invoice, by its Id. So you will create a filter set GetById.
Then your application has an approval workflow for the invoices. So you create another filter set GetByInvoiceState. This filter set will contain a filter, which will load invoices by their state. This filter can additionally contain a parameter, so when loading the data, you will have to provide an Id of the requested invoice state.
