TreeList selected row on expand/collapse event

Hi,

please help to set k-selected class on expand/collapse event in treeList (angular 16 app).

By default rows are highlighted on select event (k-selected class applied), but I need to highlight it on expand, collapse, select events.

I was trying to use rowCallback for setting/removing selected class and expand/collapse events for getting selected row id, but currently several rows are staying selected at the same time when should be selected only one (from the last action). Am I missing something, or is there a better approach?

rowCallback = (context) => {
return this.zone.run(() => {
if (context.dataItem.id === this.selectedNodeId) {
return {
'k-selected': true
      }
    }
else if (context.dataItem.id === this.previousSelectedNodeId) {
return {
'k-selected': false
      }
    }
  });
}
onAction(e) {
this.zone.run(() => {
const row = this.treeList.view.data.find(dataItem => dataItem.data.id === e.dataItem.id);
if (row) {
this.previousSelectedNodeId = this.selectedNodeId;
this.selectedNodeId = row.data.id;
    }
  });

}
 
<kendo-treelist #treeList kendoTreeListExpandable kendoTreeListSelectable
  [data]="(loadNodes$ | async)"
  [fetchChildren]="fetchChildren"
  [hasChildren]="hasChildren"
  (selectionChange)="onSelectionChange($event)"
  [rowClass]="rowCallback"
  (expand)="onAction($event)"
  (collapse)="onAction($event)">

Drag and drop from Kendo Grid to Kendo Tree and vice versa for Kendo Angular UI Components

Hi Members,

I have been trying to achieve drag and drop between Kendo Grid to Kendo Tree and vice versa but unable to find a feasible solution.

Is it possible to do so, if yes then can you please let me share some example of if someone has implemented something similar.

By default i think it doesn't support dragging and dropping from Kendo Angular Tree Control to Kendo Angular Grid Control

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:
