Subscribing to ngControl's observables and status events in the constructor breaks if you use the formControl
directive. If you put it in ngOnInit
it works as expected.
ngOnInit() {
if (this.ngControl) {
this._value = this.ngControl.value;
this._disabled = this.ngControl.disabled;
this.ngControl.statusChanges.pipe(untilDestroyed(this)).subscribe(s => {

this.ngControl.valueChanges.pipe(untilDestroyed(this)).subscribe(v => {
this._value = v;
this.host.detectChanges();
this.stateChanges.next();

this.host.changeEvent

Thanks very much for publishing this, this is helping me loads!
When I use that I got a double Label and a double line under the field.. Is this expected ?
Thanks !
Yes you are rigth wibimaster, but is because ng-select is creating its own label and field and mat-form-field y doing the same. The _ng-select-theme.scss posted here hides the doble lable and line so you are not loading the scss file correctly.
When i used this with 'formControl', 'ngcontrol' valuechanges is not working .
this.ngControl.valueChanges.pipe(untilDestroyed(this)).subscribe(v => {
this._value = v;
this.host.detectChanges();
this.stateChanges.next();
});
this is not working. Can anyone look into this.
As I had issues with the approach above, I went to the source and did some minor modifications and got a usable result with minimal changes (all commented in the source). Now I'm able to use kendo angular controls with this directive inside mat-form-fields.
