The code is down below.

How to clone/copy scheduler events in Telerik Kendo UI for angular ?

I am using Kendo UI timeline view for scheduling events in a day.

I want to provide a feature where user can clone (create a copy of) existing events and edit them as required in order to minimize their work.

I found this concept in jQuery where they are cloning events using keyboard shortcuts(https://docs.telerik.com/kendo-ui/knowledge-base/clone-events-on-ctrl-and-click) but there is no way available to do the same in Angular.

Kindly help in achieving this feature as I am new to Telerik UI.

How to programmatically insert nodes into a treeview with remote data

My treeview is defined as follows:

<kendo-treeview
#treeView
kendoTreeViewExpandable
kendoTreeViewSelectable
(selectionChange)="edit($event)"
[(expandedKeys)]="expandedKeys"
textField="text"
[filter]="filterTerm"
[nodes]="keyValues$ | async"
[children]="fetchChildren"
[hasChildren]="hasChildren"
>

As the screen is opened I set the expandedKeys so that some of my nodes are by default opened, and the data is automatically loaded in.

However certain nodes have children which I would also like to load when their parent is opened, and to further complicate the matter, a different call to the server is required than the one defined in fetchChildren for fetching this data.

Is there any way I can independently load this data, not using fetchChildren and then programmatically insert it into the tree? It seems as though there isn't a way to perform a hybrid approach to data loading...

Angular Grid, Allow wrapping of column header text upon resizing only

For the Angular Data Grid, I use the autoFitColumn property as below to expand all the columns to take the maximum width of the column. I have large column names and default is set to not wrap hence column widths are as per the column names and not the content. This is desired behavior on initial rendering. However upon user resizing of columns, I would like column names to wrap, I am not able to figure this one out.
If I set the css property as below to normal then on initial rendering, it will wrap column name and I do not want that

Also how to add a tooltip to the column name. This helps with resizing which cuts the header with ellipsis

public ngAfterViewInit() {

if (this.grid && this.grid.columns) {
this.grid.columns.forEach((item, index) => {
if (!this.isColumnWidthSet(item.field))
this.grid.autoFitColumn(item);
});
}

}

css property to use

.k-column-title
{
white-space:normal;
}

Activate Kendo License before build in YAML causes error "License key signature is not valid"

Hi together,

On my local environment my license activation works well - I use the license key file there. But during deployment, I have a problem with the license activation - I need it because I call ng build there. I use an environment variable there.

This is how I do the license activation during deployment with Azure DevOps and YAML script:

I've added a variable inside my DevOps library named KENDO_UI_LICENSE. The value of the variable is the content of my local license key file. The variable is a secret variable, but I have the same problem, if it is a normal text variable
In my YAML file I do the following steps:

- task: Npm@1
        displayName: Install Packages for Angular Client
        inputs:
          command: ci
          workingDir: '<my working dir>'

- script: 'npx kendo-ui-license activate'
        displayName: Activate Kendo UI License
        workingDirectory: '<my working dir>'
        env:
          KENDO_UI_LICENSE: $(KENDO_UI_LICENSE)

- task: Npm@1
        displayName: Build Angular Client
        inputs:
          command: custom
          workingDir: '<my working dir>'
          customCommand: 'run build'

Everything works well except the "Activate Kendo UI License" script, there I get the error "License key signature is not valid". I think there is a problem with the environment variable.

Here is the output of the DevOps Pipeline console:

For 'npm ci':

> @progress/kendo-licensing@1.2.2 postinstall D:\agent\_work\1\s\DSO.Isys.Web.Client\IsysApp\node_modules\@progress\kendo-licensing

> node ./bin/kendo-ui-license.js activate --ignore-no-license

(INFO) Kendo UI: KENDO_UI_LICENSE environment variable not set

For 'npx kendo-ui-license activate':

Skriptinhalte:

npx kendo-ui-license activate

========================== Starting Command Output ===========================

"C:\Windows\system32\cmd.exe" /D /E:ON /V:OFF /S /C "CALL "D:\agent\_work\_temp\ed2dfcbf-634f-43e2-8232-208b8ca7e658.cmd""

(INFO) Kendo UI: Reading license from KENDO_UI_LICENSE environment variable...

(ERROR) Kendo UI: License key signature is not valid. Please, download a new copy of the license and try again.

##[error]"Cmd.exe" wurde mit dem Code "2" beendet.

What am I doing wrong here?

Thanks for your help,

Katharina

[Solved] Display Value with Label

I am using a donut chart and have data with wide varying data values. This means that some of the individual segments can be very small. I would like to display the value next to each label e.g. Active [890], Backlog [2156], Rejected [2].

I need this for both labels around the chart or in the Legend on charts where I only display the legend.

Attached chart shows an example of my chart. The yellow highlights are where I'd like the data value to appear.

Thanks
