This works for me in .net Core 3 …
allowPaging="true" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Search"})" actionComplete="actionComplete">
<e-data-manager url="/Cargos/UrlDataSource" adaptor="UrlAdaptor" insertUrl="/Cargos/Insert" updateUrl="/Cargos/Update" removeUrl="/Cargos/Delete"></e-data-manager>
<e-grid-searchsettings fields="@(new string[] { "Codigo","Nombre"})"></e-grid-searchsettings>
In controller file
public IActionResult UrlDataSource([FromBody]DataManagerRequest dm)
{
IEnumerable<CargoSet> DataSource = _context.CargoSet.OrderBy(o => o.Codigo).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<CargoSet>().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);
}
In Startup file
services.AddControllersWithViews().AddNewtonsoftJson(options =>
{
options.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
I hope it serves…
