Hello,

I ran into an issue using the multicolumncombobox. I want to fill this dropdown with data rertrieved from my Rest API Java backend. Although the data shows up, I get an error in my console looking like this:

core.mjs:8453 ERROR Error: Provided data must consist only of objects. See https://www.telerik.com/kendo-angular-ui/components/dropdowns/multicolumncombobox/data-binding/
    at MultiColumnComboBoxComponent.verifySettings (progress-kendo-angular-dropdowns.mjs:9690:19)
    at MultiColumnComboBoxComponent.ngAfterContentChecked (progress-kendo-angular-dropdowns.mjs:4400:14)

...

Here's my template code:

<kendo-multicolumncombobox
      #list
      [data]="list"
      [listHeight]="300"
      textField="name"
      valueField="customerid"
    >
    
    <kendo-combobox-column field="name" title="name" [width]="200">
    </kendo-combobox-column>
    <kendo-combobox-column field="customerid" title="ID" [width]="200">
    </kendo-combobox-column>

My component:

list: Customer[]=[];
...
constructor(private api:CustomerService){
      this.api.getAllCustomer(this.params).subscribe((resp) => {
        this.list = resp;
        tap(()=>this.loading = false)
      });
    }

CustomerService:

 public getAllCustomer(params: any): Observable<Customer[]> {
   params.pldId='23';
    return this.api.getAllCustomer(params);
  }

The backend an retrieving the data from the backend works fine. However, the multicolumncombobox doen't really like my Array.

If I replace the list with the data from the example, it does work without an error (thats the prodictsliste from https://www.telerik.com/kendo-angular-ui/components/dropdowns/multicolumncombobox/). MAybe noteworthy, that my backend produces response of "application/son".

Any help is greatly appreciated!

Hi, 

I am trying to use toggleable button in my angular app to allow user to display some data automatically (or not).

My first question is, if user sets that he wants it, I save this in my database, and next time when user returns, I want to set the state of the button to be toggled. However, I can't find any property or anything to do this.

Is it possible at all and how if it is? :)

Second thing that I noticed is that, when I toggle button, it gets its style correctly, but when I click further, it reverts to its visual as if it wasn't toggled. This is my button setup..and I use the button as part of kendo ui angular app bar.

Thank you.

Hello,

I'm looking for some guidance on how to implement pdf viewer on kendo ui, I'm thinking To use PDF.js.

My thinking process is as below:

1. I would like to have a button on my Kendo Editor
2. The user click on that button
3. A window will display and it will contain two fields and two buttons:
   • PDF URL
   • Heigh
   • Confirm button
   • Cancel button
4. If the user click on the confirm button
   • The pdf will show as embedded pdf
     

5.  If the user clicks on Cancel

6. The process will not execute and the user will be back at the kendo editor

Based on your experience what can you recommend?

Thanks in advance,

Sunny Carrandi

When implementing the ContextMenu the items do not contain the required icons.

I used the object notation from the example

{text: string, icon: string}

I tried to hard code the value in the html template

<kendo-contextmenu [target]="target">
      <kendo-menu-item text="My Web Site" icon="trash">
                    <kendo-menu-item text="images" icon="folder">

and I tried using a template and assigning the icons via [ngClass].

Nothing works.

I get an icon but it's always a downward chevron.

Any idea what might be causing this issue?
Could the icon font be overwritten?

Hello,
I am generating a template that contains a dynamic button panel, and I need to assign a click event to an <a> element within a dynamically generated <li> list. I get the values ​​from a Json object.
The function value of each element of the list comes from a Json object value (fieldChildren.action), but when trying to assign the event (click)="fieldchildren.action", it is not being created correctly.
Please help me with some indication in this regard.
I am using kendo multistep form with angular 15

We have a problem whereby the paging dropdown is displaying the number list dropdown on all views:

Does anyone have any suggestions as to what might be happening here? I assume the dropdown should only display on small screens, not on large.
