Hi

Reasking the same question below that some else asked in 2016 from here https://www.telerik.com/forums/expressionbuilder-expression(filters)-in-kendo-mvc-grid-not-working-for-navigation-collection 

Is this still the same answer 5 years on?

Cheers

Kyle

Original Question from 2016

"We are using Kendo MVC Grid in our application. We are using LINQ to EF to query the tables.

Following is a query in our application:

query.Where(ExpressionBuilder.Expression<ParentTable>(command.Request.Filters))

This works fine as long as the filters are any columns from the "ParentTable". However, the ParentTable has a navigation collection ICollection<ChildTable> and the ChildTable has a property ChildProperty and the method ExpressionBuilder.Expression fails when we use this ChildProperty for filtering.

Any solution for this problem?

Thanks"

"Hi,

I'm copying my reply to your support ticket here for customer reference.

I'm afraid the Where extension does not support filtering by collection.
This is not a design goal of the data engine.

Using the Kendo UI Editor successfully in my application, I recently try to implement a dark mode through an external library.

To my surprise, the editor itself seems to be not able to work correctly in dark mode in general.

I.e. I see dark font color on dark background.

Even the very own demos with the very own Telerik skins fail to work correctly. E.g.:

demos.telerik.com/kendo-ui/editor/index?autoRun=true&theme=material-main-dark

I found no way and no CSS to specify a light default text color.

My question:

How can I configure the Kendo UI Editor to correctly work with a dark background?

Is there a way to accomplish this in kendo MVC?

Hello, I followed the example described here to add a new row to a grid for .net core. 

https://demos.telerik.com/aspnet-core/grid/editing-custom?_ga=2.26293876.833224250.1638885818-877575679.1613496852&_gac=1.254567930.1636639521.CjwKCAiAm7OMBhAQEiwArvGi3LGIkgkIa0cryh_i3sqYkeTw5t6X4lLPrldP-jBbXgDwqmTnAOAOkhoC-yQQAvD_BwE

All works fine as it is in the example but if I change the GridEditMode to Popup then when it opens the popup it doesn't show the editor template DropDownListFor.

Can you help me out in order to have this working with the GridEditMode.Popup ?

Thanks,

Pedro

I want to add checbox to my grid. I tried to use the Select() method but the method shows an error No overload for method Select takes 0 arguments.  I need to pass to controller a collection of id elements that the user has selected.

    @(Html.Kendo()
             .Grid<Model>()
             .Name(gridId)
             .Columns(col =>
             {
                 col.Select();
                 col.Bound(fds => fds.Id);
                 col.Bound(fds => fds.CreateDateTime).ClientTemplateDateTime();
                 col.Bound(fds => fds.IdClient);
             })
             .Pageable()
             .Sortable()
             .DefaultPageable()

Hi,

I have a Model object which is used to create the parent Kendo Grid. This Model object contains a list of object which is used as a data source to another nested grid created with a ClientDetailTemplate and DetailInit event. The nested grid is coming up fine but I am unable to perform any grid operations like sorting or filtering. It does not give any error but the grid just closes down.

I think I might be missing some configuration in DetailInit event method to make sure the sorting/filtering operations does not do server operations. So I used  grid.dataSource.serveroperation = false; in detailInit event. still the grid just closes in and looks like its trying to do server operation for sorting and filtering. Following is an example of the code that I am using:

public class ParentModel
   {
      public long ParentId { get; set; }
      public List<ChildModel> ChildModelList{ get; set; }
      ...
   }

@(Html.Kendo().Grid<ParentModel>()  
    .Name("Grid")
    ...
    .ClientDetailTemplateId("nested_grid")
    .Events(e => e.DetailInit("detailInit"))
    ...
)
  
<script id="nested_grid" type="text/kendo-tmpl">
    @(Html.Kendo().Grid<ChildModel>()
               .Name("ParentModel_#=ParentId#")
               .Sortable()
               .Filterable()
               .ToClientTemplate()
     )
</script>
  
<script>
    function detailInit(e) {
        var grid = $("#ParentModel_" + e.data.Name).data("kendoGrid");
        grid.dataSource.data(e.data.ChildModelList);
        grid.dataSource.serveroperation = false;
        }
</script>
