Asked On July 8, 2019 05:09 PM UTC

Hi all,
I followed several examples on this forum on "how to use the grid with the razor page", but it doesn't work.
The test project is attached.
If I use the example using the datasource binding, the grid fills up,
If I use <e-data-manager> the events don't fired and the grid "no record to display"... how can I solve this problem?
Thank you

Hi, thanks for the quick answer.
I tested your example and now the Crud operation works well,
But I wanted to tell you, that if you enable allowSorting = "true" in your example it doesn't work

Thanks again

Hi Aguzz, 

We have validated your query. While using remote data you need to handle the on demand actions in server side. Please find the below code snippet and sample for more information. 

Index.cshtml.cs 

public JsonResult OnPostDataSource([FromBody]DataManagerRequest dm) 
        { 
            IEnumerable DataSource = OrdersDetails.GetAllRecords(); 
            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 ? new JsonResult(new { result = DataSource, count = count }) : new JsonResult(DataSource); 
    } 


Please get back to us, if you need further assistance. 

Regards, 
Thavasianand S.
