DataManager Operations: The query parameters are serialized by the DataManager class and the server-side operations such as sorting, filtering, paging are performed by the PerformSorting, PerfomWherFilter, PerformSkip and PerformTake methods. C# DataOperations Method: You can also perform the server side operation such as filtering, paging and sorting by using the DataOperations Execute method instead of using the individual methods.

| I use DataManager to query JSON result from DataSource like this: var dm = ej.DataManager("Home/GetOrders").executeQuery(ej.Query().where("OrderID", "equal", 1, true)); There is no results. My JSON result from DataSource action like this: [{"result":[{"ID":2,"OrderID":1,"Country":"USA","City":"Canada"],"count":1}]; But if I assign var jsondata = [{"ID":2,"OrderID":1,"Country":"USA","City":"Canada"] and use ejQuery, it return 1 record. Do you have any suggestion to find OrderID from DataSource? | |||||
