What I'm trying to do is open a modal from another component, however I keep getting this error TypeError: Cannot create property 'validator' on string 'test1' when component1.html loads because childModal is included. How can I get rid of these errors and implement this properly?


<button type="button" class="btn btn-outline-primary btn-lg" (click)="modal.showModal()">Test
<child-modal #childModal ></child-modal>


 @ViewChild('childModal') childModal: ModalComponent;


<div bsModal #childModal="bs-modal" class="modal fade" tabindex="-1" role="dialog>
    <div class="modal-dialog modal-lg">
      <div class="modal-content">
          <input type="text" formControl="test1">
          <input type="text" formControl="test2">


constructor(private modalService: BsModalService) {
    this.form = new FormGroup({
      'test':                     new FormControl(),
      'test2':                    new FormControl()

If you're trying to open a Modal Component from another Component, then this is the right way to do it with ngx-bootstrap:

import { Component } from '@angular/core';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class';

/* This is the Component from which we open the Modal Component */
  selector: 'my-component',
  templateUrl: './service-component.html'
export class MyComponent {
  bsModalRef: BsModalRef;
  constructor(private modalService: BsModalService) {}

  public openModalWithComponent() {
    /* this is how we open a Modal Component from another component */
    this.bsModalRef =;

/* This is the Modal Component */
  selector: 'child-modal',
  template: `
    <div class="modal-header">
      <h4 class="modal-title pull-left">Title</h4>
      <button type="button" class="close pull-right" aria-label="Close" (click)="bsModalRef.hide()">
        <span aria-hidden="true">&times;</span>
    <div class="modal-body">
    <div class="modal-footer">
      <button type="button" class="btn btn-default" (click)="bsModalRef.hide()">Close</button>
export class ChildModalComponent {
  constructor(public bsModalRef: BsModalRef) {}

template of the Component which is calling the Modal:

<button type="button" class="btn btn-primary" (click)="openModalWithComponent()">Create modal with component</button>

So you should NOT include the Modal Component in the template like this:

 <child-modal #childModal ></child-modal>

  • Can you reproduce it in plunker?
  • How can I call the openModalWithComponent() from another components HTML page? Doesnt it have to exist in the same component in order to be able to call it like that?
  • as I showed in my answer, in another component's HTML page you can trigger the execution of a method (in my example the method is openModalWithComponent() triggered by clicking a <button>). Then from the method you can open any Modal Component by using assuming that modalService is of type BsModalService, as shown in my code.
  • It doesn't work. I am trying to call this.bsModalRef =; from my above code and it just shows an overlay but the actual page doesnt show up. In your above example are both the components in different files? Thats how I have it set it up I dont want a single file since I will have 3 different modals
  • Okay I figured it out. I had to take out the reference to bsmodal in child component. The problem now is that after taking out the first line of modal.html the modal now opens up as small instead of large. BTW Thank you for your help!
  • I'm getting an error No component factory found for <component>. Did you add it to @NgModule.entryComponents?. My code is exactly like how you have it here, what am I doing wrong?
  • "If you use same component then," the title of the question says the opposite of this "how to open from another component".
  • The point is that you haven't answered the question being asked.
  • @AnikeshDhanokar @ViewChild('template') elementView: ElementRef; did the trick
  • thanks @AnikeshDhanokar you save my day
