kendo grid odd behaviour around service instantiation

I'm using a Kendo Grid in an Angular template and trying to allow a service in the component to define some css styling but having a problem.


<kendo-grid
*ngIf="canLoad()"
[data]=etc...
[rowClass] = "rowCallback"
>

public canLoad() : boolean
{
  return this.myservice !== undefined;
}

public rowCallback(context: RowClassArgs)
{
  this.myservice.doSomething();
}
I get an error "Cannot read properties of undefined (reading 'doSomething')"
 ... why do I get an error when the ngIf check has evaluated myservice 
as being instantiated? How can I get the rowCallback to wait until the 
service has been instantiated?
... also
I read a previous Telerik forum response where an employee stated 
"The rowClass callback function is directly passed as a value to the ngClass directive, 
which is then applied on each row." ... so just to see if my problem was a behaviour of Angular itself I
added <div [ngClass]="rowCallback()">testing...</div> and myService was available and the doSomething() 
method was called.

MultiColumnComboBox conditionally hide column

I need to conditionally hide some of the columns of my kendo-multicolumncombobox based on whether or not the field they are bound too contains a value I know that the kendo-combobox-column has a hidden property but I don't know how to get access to the bound dataItem in order to determine if it has a value.

Basically I want to be able to do:

<kendo-combobox-column field="myField" title="cc2" [width]="50" [hidden]="!myField"></kendo-combobox-column>

this throws an error how do I get access to the value of that field for this particular item?

Second Treeview behide *ngIf

I am trying to make drag drop work between two treeviews. My second treeview is under an *ngIf and does not always exist.

I have included 'dropZoneTreeViews' in both tree layouts. '(nodeDrop)' event does not fire on the second tree when visible.

I have a work around: If I add a '@ViewChild' to the component for the second 'TreeViewComponent' then events fire, but Angular throws an 'ExpressionChangedAfterItHasBeenCheckedError' error.

Can you advise any Help?

kendo treelist excel arraylist, fild does not receive array?

I have the following situation, a component with treelist where the column receives an array by ngTemplate referencing the field.

 <kendo-treelist-column
    *ngIf="!isHidden('progress')"
    field="progress"
    title="Progress"
    [width]="320">
    <ng-template kendoTreeListCellTemplate let-dataItem let-group="cellContext">
      <app-okrprogress-bar
        [showButtonOk]="true"
        [value]="dataItem.progress.slice(-1)[0].value"
        [valuePercentagel]="dataItem.progress.slice(-1)[0].value"
        [showSlider]="!dataItem.contents ? true : false"
        [showValue]="dataItem.typeProgress == 'Values' ? true : false"
        [showChecbox]="dataItem.typeProgress == 'Boolean' ? true : false"
        [stepSlider]="dataItem.typeProgress"
        [viewValue]="dataItem?.values"
        (newPercentageActive)="
          changePercentage($event, group.viewItem.parent.data, dataItem)
        "></app-okrprogress-bar>
    </ng-template>
  </kendo-treelist-column>

Now I have to export this column in excel, but the field only waits for a simple variable or objects.

  <kendo-treelist-excel>
    <kendo-excelexport-column fild="keyName" title="Objective"></kendo-excelexport-column>
    <kendo-excelexport-column fild="progress.slice(-1)[0].value" title="Progress"></kendo-excelexport-column>
    <kendo-excelexport-column fild="status.status" title="Status"></kendo-excelexport-column>
  </kendo-treelist-excel>

I did some tests of different calling modes but none of the results were effective.

This is the interface:

interface ObjectiveResult {
  keyName: string;
  progress: Progress[];
  status?: Status;
}

interface Progress {
  value: number;
  date: Date;
}

interface Status {
  name: string;
  color: string;
}

Current results:

Kendo UI for Angular scheduler timeline view multiple departments but not same attendees

Hi,

We are working with Kendo UI for Angular and having scheduler timeline view as one of the component. We have below query related to Kendo:

We have two sections on the Y-axis: department & attendees. As shown in the screenshot below, under Mechanics three names are there: Alex, Bob, Charlie.

Similarly, we want to have multiple departments but not same attendees will be there in all departments.

We want different or same attendees under different departments based on the business need.

Kindly clarify if it is possible to have this with angular & how?

Drag and Drop hintTemplate position

Hi.

I'm using the Drag and Drop functionality (https://www.telerik.com/kendo-angular-ui/components/utils/draganddrop/) and I have an issue with the hintTemplate.

I'd like to be able to reposition the drag hintTemplate. Currently, if the element you are trying to drag was first outside the viewport (for example, you want to drag an element in a scrollable list and the item is at the bottom of the list), the drag hintTemplate will be created at that position. Is there a simple way to position the hintTemplate at the cursor position?

Thanks!

Error installing Indicators

I have been trying to install the indicators

When installing I get the following: NPM install @progress/kendo-angular-indicators

While resolving: kendo-angular-app@0.0.0
Found: @progress/kendo-angular-common@2.0.3
node_modules/@progress/kendo-angular-common
  @progress/kendo-angular-common@"^2.0.3" from the root project

Could not resolve dependency:
peer @progress/kendo-angular-common@"^3.0.0" from @progress/kendo-angular-indicators@2.0.0
node_modules/@progress/kendo-angular-indicators
  @progress/kendo-angular-indicators@"^2.0.0" from the root project

Fix the upstream dependency conflict, or retry
this command with --force or --legacy-peer-deps
to accept an incorrect (and potentially broken) dependency resolution.
