Unlocking the Power of Data Passing Through Tabs

Question

Unlocking the Power of Data Passing Through Tabs

My Application Structure

Client Module - Material Tab

Tab 1 - Customer Table View
Tab 2 - Edit Customer View

<mat-tab-group>
  <mat-tab label="View">
    <div>
      <app-customer-table></app-customer-table>
    </div>
  </mat-tab>
  <mat-tab label="Edit">
    <div>
      <app-customer-create></app-customer-create>
    </div>
  </mat-tab>
</mat-tab-group>


When the "edit" icon within Tab 1 is clicked, I aim to transition to Tab 2 and transmit my "customer:CustomerDTO" data.

What steps should I take to accomplish this?

To exchange data between components in Angular, you can utilize @Output in the sending component to store a value in a variable and then use @Input in the receiving component to access that variable.

Here is an example of how it can be implemented:

<mat-tab-group>
        <mat-tab label="View">
            <div>
                <app-customer-table (onClickEdit)="edit($event)"></app-customer-table>
            </div>
        </mat-tab>
        <mat-tab label="Edit">
            <div>
                <app-customer-create [customerId]="customerId"></app-customer-create>
            </div>
        </mat-tab>
    </mat-tab-group>

    // main-componet.ts file

    edit(value)=>{
        this.customerId = value;
    }

    // customer-create.component.ts

    @Input CustomerId;

    // customer-table.component.ts
    @Output onClickEdit = new EventEmitter<string>();

    edit(value)=>{

    }

    // customer-create.component.ts

    @Input CustomerId;

    // customer-table.component.ts
    @Output onClickEdit = new EventEmitter<string>();

To accomplish this task, follow these steps:

Begin by creating a service using the following command:

ng generate service data-handling

Within that service, define two variables to hold the data for each component:

import {Injectable} from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class DataHandlingService {
  public firstTabData;
  public secondTabData;

  constructor() { }

}

Implement the service in your component:

import {DataHandlingService} from '...';

...
constructor(public dataHandlingService: DataHandlingService) {
}

Assign the data for each component to their respective variables:

setData(first, second) {
  this.dataHandlingService.firstTabData = first;
  this.dataHandlingService.secondTabData = second;
}

Utilize the desired data in the tabs

You also have the option to create a data variable and store the information there instead of using separate variables

If you need to pass data to a component, there are a few ways you can do it. One option is to use a service, while another is to utilize property binding and event binding syntax like so:

For tab1, you can employ an EventEmitter. When the user clicks on edit, call the emit function to send over the necessary data.
By using event binding, you can then retrieve this data in the parent component and transfer it to the child component through property binding.

You can find more information here:

To switch tabs, access the <mat-tab-group> in your component.ts file by using the @ViewChild decorator and adjust the selectedIndex property accordingly.
