I created an odata client like this tutorial : "Create an OData v4 Client App".
but " Connecting Telerik Reporting to OData feeds" tutorial dont't help me
i created this function :
internal static IEnumerable<EzCentral.Models.Erp.Client> ListAllClients(Default.Container container)
but in report viewer in "Edit expression" i dont't find this method.
i used the external assemblies with custom user functions in the Report Designer :
so my problem is binding my function with objectDatasource. usually the object data source was empty
