    Hi @krushnakant

    I'm not sure what you mean by EF API. You should encapsulate your parameters with DTO and you can generate queries with those parameters in the repository.

    It's not recommended that expose entities or database queries directly to the client.


    If you mean passing MaxResultCount and SkipCount parameters, you can send them manually.

    this.authorService.getList({ "maxResultCount": 2, "skipCount": 4 });

    Does your DTO has filter parameters that you want to send?

    Firstly you have to add parameters to your DTO and re-generate the client-proxy. Then you can pass those parameters that you've added to your dto. Then you can use however you want those parameters in the appservice.

    • Add Filter property to your dto, *if you don't use a specific DTO, create new one and replace PagedAndSortedResultRequestDto with it. *
    public class AuthorFilterDto : PagedAndSortedResultRequestDto
        public string Filter { get; set; }
    • Generate again the proxy in angular project.
    abp generate-proxy -t ng

    Then you can pass that parameter to the API via proxy.

     "maxResultCount": 2, 
     "skipCount": 4,
     "filter": "some filter text"

    Can you please share an example scenario? Then we can understand the issue clearly.

    I done with same our book author example. In book author example not define pass filter value. Also you are not define page size parameter. Please refer our existing Book Author example and try to pass filter value.Our example is not fulfill to the developer. please correct it and introduce new one example. in angular example is not completed so please all things complete.

    you want example of filter please go with Book Author application and pass Filter with angular to our Entity Framework API
