Hide 1st previous button & disable next button

[Stan92]

Hi,

Is there a way to hide the "previous button" on the first step Pane ?
Setting the toolbarSettings.showPreviousButton to false it hides as expected the button.
But if I set it to true (in the stepChanged event) it doesn't display it back.

Also, how to "disable" and "enable" the next button until the "validation part" is done?

thanks

initiate wizard configuration

config: NgWizardConfig = {
    selected: 0,
    theme: THEME.default,
    toolbarSettings: {
      showPreviousButton: false,
    }
  };

inject ngWizardService to constructor

constructor(private ngWizardService: NgWizardService) {}

to show it back inside your method fire stepChenged() event from ngWizardService

      this.config.toolbarSettings.showPreviousButton= true;
      this.ngWizardService.stepChanged();

Html :

<ng-wizard [config]="config" (stepChanged)="stepChanged($event)">
<ng-wizard-step [title]="'NAME'" [description]="'Name'">
<a class="btn btn-success mx-2" *ngIf="!firstStep" (click)="previousStep()">Précédent</a>

ts :

stepChanged(args: StepChangedArgs) {
    this.ngStep = args.step.title;
    switch (this.ngStep) {
      case 'NAME':
        this.firstStep = true;
        this.lastStep = false;
        this.showSave = false;
        break;
      default:
        this.firstStep = false;
        this.lastStep = false;
        this.showSave = true;
        break;
    }

This is the best I have found.

Using the template variable and ViewChild, we can access the NgWizardComponent.

Html
<ng-wizard [config]="config" #ngWizard (stepChanged)="stepChanged($event)">

Component
@ViewChild('ngWizard') ngWizard: NgWizardComponent;

and in the StepChanged event, we can set the show buttons.

stepChanged(args: StepChangedArgs) {
if (args.step.index == 0){

  this.ngWizard.showPreviousButton= false;
  this.ngWizard.showNextButton= true;
}
else{

  this.ngWizard.showPreviousButton= true;
  this.ngWizard.showNextButton= false;

}
