how to bind selected value in dropdownlist in angularjs
angularjs set selected option value

I have searched far and wide. What I got from other answers is that I need to use [selected] if I want to select a particular option.

It does not seem to be working. Why? Here is what I have:

<ngx-datatable-column name="status" prop="operationStatus" [flexGrow]="1">
    <ng-template let-value="value2" let-row="row" let-rowIndex="rowIndex" gx-datatable-cell-template>
          <select class="geraeteStatus" [(ngModel)]="selectableGerateStatus">
             <option *ngFor="let e of selectableGerateStatus" [ngValue]="e" 
                 [selected]="e.id === value2">

I am sure that the value of e.id equals that of value2 at least once per iteration. However it just does not work. Actually I can put whatever I wish (e.id === 2, or even 'true') into [selected] it does not have any effect. I have no idea what I am missing. Any answer is highly appreciated.

There is no need to use [selected] in your options

just do some changes like below


<select class="geraeteStatus" (change)="onChange($event)" [(ngModel)]="selectedStatus">
   <option *ngFor="let e of selectableGerateStatus" [ngValue]="e.id">

but here you need to match ngValue with your ngModel then only it will be selected.


selectedStatus: string;

onChange(status: string) {
   this.selectedStatus = status;

ngOptions, When an item in the <select> menu is selected, the array element or object property By default, ngModel watches the model by reference, not value. collection, ngOptions won't be able to set the selection, because the objects are not identical. <select ng-options="item as item.label for item in items track by item.id"� In this Angular tutorial, I’m going to share with you how to work with Angular 7|8|9 Select Dropdown.

Bind the option with value instead of ngValue as below.

<select class="my-status" [(ngModel)]="myModel.status">
         <option [ngValue]="null" selected disabled> Select Status </option>
         <option *ngFor="let e of selectableGerateStatus" [value]="e">

ngSelected, Blog � Twitter � Google+ � Feature & Bug Tracker � Mailing List � IRC � Gitter Sets the selected attribute on the element, if the expression inside ngSelected is truthy . is necessary because we cannot use interpolation inside the selected attribute. on the options, as ngModel will set the select value and selected options. The options property returns the collection of all the option elements in the <select> dropdown list. The elements are sorted according to the source code of the page. The index found before it can be used with this property to get the selected element. This option’s value can be found by using the value property.

I present how I solved the problem. Note that I am quite new to angular, and my approach might be rudimentary. I also want to give credit to @Eliseo who highlighted the fact that ngModel and selected must not be used together. That's whay I got rid of the former and used selected only:


 <select class="geraeteStatus" (change)="changeGaerateStatus($event, rowIndex)">
          <option *ngFor="let e of selectableGerateStatus" [selected]="value == e.id">

and the .ts file:

    this.selectableGerateStatus = [
    id: 0,
    label: BaseDataComponent.NEW
  }, {
    id: 1,
    label: BaseDataComponent.ACTIVE
  }, {
    id: 2,
    label: BaseDataComponent.DEINSTALLED

It solved my problem, but it might not be the best approach. Feel free to comment.

  • if you're using [(ngModel)] you must NOT use [selected]. The problem is that you're using [ngValue]="e". So, the variable "selectableGenerateStatus", is an object -really you need that it's was the same object. Use [ngValue]="e.id" to work
  • OK, I got it. I removed 'selected'. I changed to the following: <option *ngFor="let e of selectableGerateStatus" [ngValue]="e.id"> {{e.label}}</option> . But it still does not work
