Hi,

i am using ASP.NET Core with a KENDO Grid which calls a Razor Page handler.

For performance reasons, the Grid is pageable, filterable and sortable.

Now we want the DataSourceRequest on the server to directly filter the MongoDB query. I am using "AsQueryable()" on the IMongoCollection, which i thought works nicely with the KENDO DataSourceResult method. 

But the speed of the MongoDB query is always slow. It does not matter if i filter the grid for just one result or if i display all results (paged).

Is this the correct way to use KENDO Grid with MongoDB "database-filtering"?

I am using the following code:

Client

Server

Hello,

I use a template column to have a Kendo style Checkbox in my grid but this is not bind to the underlying boolean value...
with a "normal" Checkbox this is possible with JavaScript but the tsyled Checkbox uses a Label for Styling... (see Picture)

how to do this with the styled checkboxes?

Hello,

Can someone please help.

I'm trying to do a simple Inline edit grid which has a datetime field but when clicking update the datetime field which is passed through to the controller has null.  It's actually replicated in the example which Progress supply.  

How do I get a valid date through to the controller? surely this is quite a big issue?  is it a locale problem?

columns.Bound(p => p.Freight);
columns.Bound(p => p.OrderDate);
columns.Bound(p => p.ShipName);
columns.Bound(p => p.ShipCity);
                    columns.Command(command => { command.Edit(); command.Destroy(); }).Width(160);

        {
            var result = Enumerable.Range(1, 50).Select(i => new OrderViewModel
            {
                OrderID = i,
                Freight = i * 10,
                OrderDate = new DateTime(2016, 9, 15).AddDays(i % 7),
                ShipName = "ShipName " + i,
                ShipCity = "ShipCity " + i
            });

            var dsResult = result.ToDataSourceResult(request);
            return Json(dsResult);
        }
        [AcceptVerbs("Post")]
        public ActionResult Orders_Update([DataSourceRequest]DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<OrderViewModel> products)
        {

     //products.OrderDate is null even though I've selected a date on the edit datepicker.
            return Json(products.ToDataSourceResult(request));
        }

    }
}

I saw that there was a demo for initial files in mvc but that disappeared in the asp.net core demos.

Thanks

In the demo : https://demos.telerik.com/aspnet-core/grid/editing-popup.

there is code shown  as follows in the ProductService.cs:

      public class ProductService : BaseService, IProductService

Where is the code for BaseService and IProduct Service?

Also, more generally, where can I download the sources to all the demos for .net core?

Thanks … Ed

I would like to use the tag helper, but I cannot set the initial files like

<files>@Html.Raw(Model.InitialFiles)</files>

I am only able to set them as static HTML list, i.e.

<files><file name="dummy" size="1024" extension=".ext"/></files>

(https://docs.telerik.com/aspnet-core/tag-helpers/editors/upload/overview)

Is it possible to use the tag helper when the file list would be obtained from a model? And how?

When I run this I get an error that says - Failed to load resource: net::ERR_SPDY_PROTOCOL_ERROR

I"m trying to filter a grid that is bound to many fields including a few that are DateTime. My filter works great until I try to do one on a datetime type field then it errors out. What operator can I use on a datetime? Here's the error and the settings for the filter.

Message"The binary operator GreaterThanOrEqual is not defined for the types 'System.DateTime' and 'System.String'."string

$("#Grid").data("kendoGrid").dataSource.filter({
            logic: "or",
            filters: [
                {
                    field: "DateEntered",
                    operator: "gte",
                    value: searchValue
                },
                {
                    field: "DateEntered",
                    operator: "lte",
                    value: searchValue
                },

Thanks!

Hi,

Is Kendo UI works with asp .Net core 2.0 ? 

If yes, can anyone have any demo on this. As, I am trying to use Kendo UI  for my asp .net core 2.0 project and I am getting some issue there.
