p-dropdown doesn't show value from form










0















I'm getting a problem when I use the p-dropdown component binding a form. I have a Form Group with Form Controls that have our own values pre-loaded and the value of one of this controls should be showed at p-dropdown component. But it isn't visible when the page load.



I use the Dropdown look like:



<p-dropdown [options]="vehicleTypes" placeholder="Vehicle Type" optionLabel="label" formControlName="vehicleType">




And my component have a Form Group that have a Form Control named vehicleType and with the value.



label: "TYPE 1", value: "1"

          Why are you having label in formcontrol? Just keep value in formControl like this:



          app.component.ts



          appForm: FormGroup;

          vehicles = [
          value: 1, label: 'v1',
          value: 2, label: 'v2',
          value: 3, label: 'v3',
          value: 4, label: 'v4',
          value: 5, label: 'v5',
          value: 6, label: 'v6',
          ]

          constructor(
          private fb: FormBuilder
          )

          ngOnInit() {
          this.appForm = this.fb.group(
          vehicleType: new FormControl(2)
          );


          app.component.html



          <form [formGroup]="appForm">
          <p-dropdown [optionLabel]="label" placeholder="Vehicle Type"
          [options]="vehicles" formControlName="vehicleType"></p-dropdown>
          </form>

          The values have to be set to your vehicleTypes like:



          vehicleTypes = [
          label: "TYPE 1", value: "1"
          ]


          and vehicleType is a FormControl like Bravin said.



          Generally, we could use first element as a placeholder.

            The values have to be set to your vehicleTypes like:



            vehicleTypes = [
            label: "TYPE 1", value: "1"
            ]


            and vehicleType is a FormControl like Bravin said.
