Failed to navigate: Template parse errors: Can't bind to 'options' since it isn't a known property of 'signature-pad'

Question

I am trying to implement angular2 signature pad in my ionic 3 project i am getting error as above my question. I am following this tutorial link. It is working fine in ionic2 but when i try in ionic 3 i am getting error like below

Failed to navigate:  Template parse errors:
Can't bind to 'options' since it isn't a known property of 'signature-pad'.
1. If 'signature-pad' is an Angular component and it has 'options' input, then verify that it is part of this module.
2. If 'signature-pad' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("
    <ion-col></ion-col>
    <ion-col>
      <signature-pad [ERROR ->][options]="signaturePadOptions" (onBeginEvent)="drawStart()" (onEndEvent)="drawComplete()"></signatur"): ng:///ConformsignModule/Conformsign.html@20:21
'signature-pad' is not a known element:
1. If 'signature-pad' is an Angular component, then verify that it is part of this module.
2. If 'signature-pad' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("
    <ion-col></ion-col>
    <ion-col>
      [ERROR ->]<signature-pad [options]="signaturePadOptions" (onBeginEvent)="drawStart()" (onEndEvent)="drawComplet"): ng:///ConformsignModule/Conformsign.html@20:6

you can get the full code in this like i just trying everything in this https://devdactic.com/signature-drawpad-ionic-2/

I think when i use deeplink navigation i am getting this error but when i import my component to app.module.ts everything is working fine

update

here is my .ts file

export class Conformsign {

  signature = '';
  isDrawing = false;
  finalData
  @ViewChild(SignaturePad) signaturePad: SignaturePad;
  @Input()
  private signaturePadOptions: Object = { // Check out https://github.com/szimek/signature_pad
    'minWidth': 2,
    'canvasWidth': 400,
    'canvasHeight': 200,
    'backgroundColor': '#f6fbff',
    'penColor': '#666a73'
  };

  constructor(public navCtrl: NavController, public navParams: NavParams, public toastCtrl: ToastController, public holders: Holders, public rest:Rest) {

    this.finalData = this.holders.getData();
  }

  ionViewDidLoad() {
    console.log('ionViewDidLoad Conformsign');
  }

  ionViewDidEnter() {
    this.signaturePad.clear()
  }

  drawComplete() {
    this.isDrawing = false;
  }

  drawStart() {
    this.isDrawing = true;
  }

  savePad() {
    this.signature = this.signaturePad.toDataURL();
    this.signaturePad.clear();
    let toast = this.toastCtrl.create({
      message: 'New Signature saved.',
      duration: 3000
    });
    toast.present();

     let conformDelivery = {
      order_id: this.finalData.order_id,
      amountpaid:this.finalData.total,
      customername:this.finalData.firstname,
      signature:this.signature,
      user_id:this.finalData.user_id,
      customer_id:this.finalData.customer_id
    }

  }

  clearPad() {
    this.signaturePad.clear();
  }

}

here is my .html

<ion-content>
  <div class="title">Please draw your Signature</div>
  <ion-row [ngClass]="{'drawing-active': isDrawing}">
    <ion-col></ion-col>
    <ion-col>
      <signature-pad [options]="signaturePadOptions" (onBeginEvent)="drawStart()" (onEndEvent)="drawComplete()"></signature-pad>
    </ion-col>
    <ion-col></ion-col>

  </ion-row>
  <button ion-button full color="danger" (click)="clearPad()">Clear</button>
  <button ion-button full color="secondary" (click)="savePad()">Save</button>

  <ion-row>
    <ion-col></ion-col>
    <ion-col width-80>
      <img [src]="signature"/>
    </ion-col>
    <ion-col></ion-col>
  </ion-row>

</ion-content>

Answer 1

I was facing this issue also. I solved this issue by going through comments on the original post by devdactic https://devdactic.com/signature-drawpad-ionic-2/

A guy named Ka mok pointed me to something

IF you are using the signature pad in a component . in my case am using it in a farmers component, the component usually have a farmer.module.ts file. So just import the signature pad module and everything should work fine

e.g

farmer.module.ts

import { NgModule } from '@angular/core';
import { IonicPageModule } from 'ionic-angular';
import { FarmerPage } from './farmer';
import { SignaturePadModule } from 'angular2-signaturepad';

@NgModule({
  declarations: [
    FarmerPage,
  ],
  imports: [
    IonicPageModule.forChild(FarmerPage),
    SignaturePadModule // this saved my life
  ],
})
export class FarmerPageModule {}

farmer.ts

import { Component, ViewChild } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { SignaturePad } from 'angular2-signaturepad/signature-pad';
import { NativeStorage } from '@ionic-native/native-storage';
import { ToastController } from 'ionic-angular';

Lastly make sure you also import the module in app.module.ts

I hope this helps someone. Thanks

Answer 2

You need to add the module to imports

import { SignaturePadModule } from 'angular2-signaturepad';

@NgModule({
  imports: [/* BrowserModule, RouterModule.forRoot(myRoutes), ... */,
      SignaturePadModule],
  ...
})
export class AppModule {
}

where AppModule is the same module that also contains in declarations: [...] the component where you are using the signature pad.

Answer 3

Import the SignaturePadModule in Confirm.module.ts since you are using ionic 3.

@NgModule({
    declarations: [
        ConfirmSign
    ],
    imports: [
        IonicPageModule.forChild(ConfirmSign),
        SignaturePadModule
    ],
    entryComponents: [
        ConfirmSign
    ]
})
export class ConfirmSignModule { }
