TL;DR: Any plans for virtualisation support on Treeview?

I've attached an example project.

The data is a set of companies. Each company has 5 offices. Each office has a collection of Drivers and a collection of Vehicles. There are 1000 Drivers and 1000 Vehicles in each.

1: Run the app
2: Expand a company
3: Expand an office
4: Expand one of the child nodes (Drivers or Vehicles)

On my computer, this takes about 7 seconds to open. I think it is a combination of adding so many DOM elements and also using an ng-template inside the tree.

This might improve in Angular6, but it seems that creating all of those DOM elements is a waste of resources anyway. Do you have any plans for supporting virtualisation in your Treeview component?

I'm getting this error:

ERROR in node_modules/@progress/kendo-angular-buttons/dist/es/navigation/navigation-config.d.ts(1,10): error TS2305: Module '".../node_modules/@angular/core/core"' has no exported member 'OpaqueToken'.

Using @angular/core version 5.2.9

I've been trying at this for a couple days and noticing the same thing, ie. that I can get a combobox to read back selected values and record them successfully to a grid, I can get a combobox on its own to take and save the new custom values to my back-end through REST, but I can't combine the two.

As far as the API's are concerned this combination works for in-grid selection:

          <kendo-combobox [formControl]="dimensionTypeGridFormGroup.get('dimensionTypeId')"
                          [data]="dimensiontypes"
                          [textField]="'name'"
                          [valueField]="'id'"
                          [valuePrimitive]="true">
          </kendo-combobox>

This for creating new content:

<kendo-combobox [allowCustom]="true"
                [data]="combolists"
                [textField]="'name'"
                [valueField]="'id'"
                [valueNormalizer]="valueNormalizer"
                [(ngModel)]="clbuilder">
</kendo-combobox>

It seems like the moment I add [allowCustom] to a combobox in a grid cell it causes two things to happen:

1) the grid cell will be blank on save

2) only the default value is saved in the grid formgroup for that cell.

In a lot of cases I could indeed save my new record to my back end but the grid would stop working. In some of my trial and error I noticed that confusion was occurring (in the combobox API references) between the form control data and the combobox data (such as 'id' in the formGroup vs. in the export interface array). 

Is there a right way to do this through the combobox API components and, if not, is there a way that I could push the values I need back to the grid from somewhere else like a valueChange or valueNormalizer method? I remember there being an edit.service push back to grid in the in-cell grid editing example but I'm not sure how to hit that from within a component yet.

Take a look at this Plunker:

What I'm trying to achieve is specifying a set of grid-columns using Angular ngFor and ngSwitch directives. Using ngFor renders fine, but once I try to introduce ngSwitch, it renders as if there were not grid-column components.

It should be possible but I'm wondering if I'm missing something?

Thanks.

I've been reading through the tutorial on creating a Master-Detail grid for Angular 4/5 and so far have been able to construct a working mock-up in VS Code without any significant roadblocks.

My current question: is it possible to retrofit the Master-Detail grid for API data received by JSON? If so what approach would you recommend - building the GridDataResult data input array within the component hosting the grid (such as is done with the programming in the grid edit examples) or is there a kendo-data-query module similar to toODataString that I can use to similar ends in northwind.services.ts under fetch and in the queries?

Eventually I'd like to incorporate full CRUD capabilities with most layers and for that reason I'm hoping to keep the read operation in the same API format as the edit, update, and delete.

Hello,

I am currently using the Kendo UI ComboBox widget in terms of a demanding Angular4 project and am facing the below issues:

1. The ComboBox is at the bottom of the page. When I open it, it is displayed as usual (and that's fine!). However, when I filter its content, the ComboBox does not respond as intended. Its expanded list does not appear exactly above the ComboBox. It remains where it was initially and there is a gap between the list and the ComboBox. Please take a look at the 3 screenshots attached in order to get a better understanding.

2. The response time for the scrolling action (outside the expanded list) seems to be much longer than it was expected. The expanded list remains for some seconds above the ComboBox. After that, the expanded list appears below the ComboBox. It is not possible to upload a screenshot for this case as it has to do with the time the expanded list needs to appear where it should without such a long delay. 

Sorry for the Greek language used in the screenshots and thank you very much in advance!

I can show a table with columns inside the ng-template kendoGridDetailTemplate mimicking the look of a grid, but I want to know if there's a possibility to have a kendo-grid in the detail template to take advantage of sorting, filtering of the inner grid.

Also, is there a grid feature for aggregating columns for kendo-grid with Angular?

Thanks!

Does a Kendo UI license cover all parts including Kendo UI controls for Angular, Kendo UI controls for jQuery, Kendo UI controls for React etc. or do we have to purchase each license separate?

If our team has to buy separate licenses for Kendo UI controls for Angular and Kendo UI controls for jQuery, where is the pricing information given?

P.S.

For the time being, our team needs only Kendo UI controls for AngularJS.
