setting value on ColorPalette

[Bob]

I have a color palette declared on my form:

<kendo-colorpalette
    #riskAssessmentColourCode
    [palette]="palette"
    (valueChange)="riskAssessmentColourCodeChange($event)"
    formControlName="riskAssessmentColourCode"
    [tileSize]="30">
</kendo-colorpalette>

I declare a handle for the color palette in my component:

@ViewChild('riskAssessmentColourCode') public riskAssessmentColourCode: ColorPaletteComponent;

I try to get a handle on this to set the initial value:

this.riskAssessmentColourCode.value = this.palette[this.lastHistory.riskAssessment.riskAssessmentColourCode];

But the component is undefined and I am unable to set the value.

I can change the form control value with:

this.ncDocumentEditForm.controls['riskAssessmentColourCode'].setValue(this.lastHistory.riskAssessment.riskAssessmentColourCode);

 

But the visible component does not set in the same way as if I select it with a mouse (i.e. the selected block is not highlighted).
The design of this forum really is a joke with popup windows appearing below headers and the user unable to exit a code block if s/he hasn't inserted a line break to jump to first.  It's a very poor user experience and, if it were advertising your components as a window no-one would select your product.  Please sort it out.
How do I set the color palette value?

Hi Bob,

Thank you for the provided feedback.

I have prepared a StackBlitz example which demonstrates the usage of the ColorPalette component within a reactive form.

In ngOnInit() method the initial selected color value of the palette is set by using the form: FormGroup element. The form element collects a FormControl color element which is attached with FormControlName="color" to the ColorPalette. I have implemented a cutom method called selectColor() which selects random color of the listed in the palette property. Every time the `Set Random Color` button is clicked the value is updated and the new one is selected. I could not reproduce the case where the selected color tile is not highlighted.

I hope this helps.

Please, let me know if I am missing something or if you need any further assistance.

Hi Elena,

Thanks very much for replying.  I was probably a little too quick off the mark to be posting and issue.  After a while of tearing my hair out trying to set the component value I found the alternative which was to set the value of the form control as you so brilliantly demonstrated in your stackblitz example.  Sorry if I wasted your time but I'm sure it will be sueful for others asking the same question.

Cheers,
Bob
