How to set value to FormBuilder object in angular 2 Typescript
<p>I am used Reactive form Validation(Model driven validation) but cant set the value to form object on Dropdown change </p>

<p><strong>This is my Formgroup</strong></p>

<pre><code>studentModel:StudenModel
AMform: FormGroup;
Name = new FormControl("", Validators.required);
Address = new FormControl("", Validators.maxLength(16));

constructor(fb: FormBuilder){     
  this.AMform = fb.group({
    "Name": this.Code,
    "Address": this.Abbrev,
  });
}
onAccntChange(event: Event) {
  // set the value from Class Model
  ////  this.studentModel 
  // how to set this.studentModel value to form
}    
</code></pre>

<p><strong>This is My html page</strong></p>

<pre><code>&lt;form [formGroup]="AMform" (ngSubmit)="submit()"&gt;
    &lt;select (change)="onAccntChange($event)" class="form-control" [disabled]="ddlActivity" formControlName="AccountManagerID"&gt;
        &lt;option value="0"&gt;Select&lt;/option&gt;
        &lt;option *ngFor="let item of allStudent" value={{item.StudentID}}&gt;
            {{item.Name}}
        &lt;/option&gt;
    &lt;/select&gt;

    &lt;div class="col-sm-9"&gt;
        &lt;input type="text" class="form-control" formControlName="Name"&gt;
    &lt;/div&gt;
    &lt;div [hidden]="Name.valid || Code.pristine" class="error"&gt; Name is required &lt;/div&gt;

    &lt;div class="col-sm-9"&gt;
        &lt;input type="text" class="form-control" formControlName="Address"&gt;
    &lt;/div&gt;
    &lt;div [hidden]="Address.valid || Address.pristine" class="error"&gt;Address is required &lt;/div&gt;

    &lt;button type="submit" class="btn btn-warning "&gt;&lt;i class="fa fa-check-square"&gt;&lt;/i&gt; Save&lt;/button&gt;
&lt;/form&gt;
</code></pre>
