Dear Team,

            I am working with syncfusion Datagrid and server side dapper ORM. 
  • i have a problem in Paging,Filtering,Searching and Sorting. kindly suggest solution for our problem
  • is there any way to create dynamic query that can be run on serverside which syncfusion internally creates using grid column filters.

Hi Pradeep, 
 
Greetings from Syncfusion support. 
 
Query: I have a problem in Paging,Filtering,Searching and Sorting. kindly suggest solution for our problem 
 
We have validated your query and we suspect that the cause of the issue is the provided dataSource type. Could you please provide dataSource as IEnumerable and check this from your side. Refer the below code snippet for your reference. 
 
[code snippets] 
public IActionResult UrlDatasource([FromBody]DataManagerRequest dm) 
        { 
            IEnumerable DataSource = db.GetAllOrders().ToList(); 
            DataOperations operation = new DataOperations(); 
            if (dm.Search != null && dm.Search.Count > 0) 
            { 
                DataSource = operation.PerformSearching(DataSource, dm.Search);  //Search 
            } 
            if (dm.Sorted != null && dm.Sorted.Count > 0) //Sorting 
            { 
                DataSource = operation.PerformSorting(DataSource, dm.Sorted); 
            } 
            if (dm.Where != null && dm.Where.Count > 0) //Filtering 
            { 
                DataSource = operation.PerformFiltering(DataSource, dm.Where, dm.Where[0].Operator); 
            } 
            int count = DataSource.Cast<OrdersDetails>().Count(); 
            if (dm.Skip != 0) 
            { 
                DataSource = operation.PerformSkip(DataSource, dm.Skip);   //Paging 
            } 
            if (dm.Take != 0) 
            { 
                DataSource = operation.PerformTake(DataSource, dm.Take); 
            } 
            return dm.RequiresCounts ? Json(new { result = DataSource, count = count }) : Json(DataSource); 
        } 
 
Please get back to us if you need further assistance. 
 
Regards, 
Thavasianand S.
