I have this message appear in my console when I want edit my user.
I see some solution on the web, Some people have trouble with it but no solution for me.
Does someone have the same problem?
EditUserDialogComponent.html:37 ERROR Error:
ngModel cannot be used to register form controls with a parent formGroup directive. Try using
formGroup's partner directive "formControlName" instead. Example:
<div [formGroup]="myGroup">
<input formControlName="firstName">
</div>
In your class:
this.myGroup = new FormGroup({
firstName: new FormControl()
});
Or, if you'd like to avoid registering this form control, indicate that it's standalone in ngModelOptions:
Example:
<div [formGroup]="myGroup">
<input formControlName="firstName">
<input [(ngModel)]="showMoreControls" [ngModelOptions]="{standalone: true}">
</div>

at debugCheckDirectivesFn (core.js:45270)
at Object.eval [as updateDirectives] (EditUserDialogComponent.html:42)
and this is my HTML,
I think it's a problem about the form control, but if I follow the instructions of the error message, I have the same...

thanks a lot for your help
The issue you are having is the usage of the ([ngModel]) inside of a formGroup.
If you need to extract a value, you will have to do it via the formGroup variable on the TS component.
Check out more information on the Angular support page: https://angular.io/guide/reactive-forms
change this:
`<input id="password" matInput type="password" placeholder="Password" formControlName="password" [(ngModel)]="selectedUser.password">`
into this:
`<input id="password" matInput type="password" placeholder="Password" formControlName="password" (change)="selectedUserChanged($event)">`
//and add to your ts
`selectedUserChanged(change: any) {
this.group.get('password').setValue(change.value);
}`
