Learn how to efficiently transfer row data or an array object to a component within Angular by utilizing the MatDialog feature

My goal is to create a functionality where clicking on a button within a specific row opens up a matDialog box displaying all the contents of that row. Below is the HTML snippet:


<tr *ngFor="let u of users">
    <td data-label="ID">{{u.name}}</td>
    <td>
        <button (click)="toggle(u)" mat-button type="button" class="btn btn-primary">
            Show Details
        </button>
    </td>
</tr>

Here is the TypeScript code:


users = [
    {
      'name':'arjun'
    },
    {
      'name':'Karan'
    }
]

toggle(userRow:any){
    const dialogConfig = new MatDialogConfig();
    dialogConfig.disableClose = false;
    dialogConfig.autoFocus = true;
    dialogConfig.width="60%";
    this.dialog.open(UserDetailsPopupComponent, dialogConfig);
}

Below is the HTML file for the component (UserDetailsPopUp) that will open using MatDialogue:

<h1>Hello {{u.name}}</h1>

I am facing an issue in passing row data from the toggle function to this component. How can I achieve this and display the data successfully?

Answer №1

To pass information to the dialog component, you can follow this example:

toggle(userDetails:any){
    const dialogConfig = new MatDialogConfig();
    dialogConfig.disableClose = false;
    dialogConfig.autoFocus = true;
    dialogConfig.width="60%";
    dialogConfig.data = userDetails;
    this.dialog.open(UserDetailsPopupComponent, dialogConfig);
  }

In order to retrieve the data in UserDetailsPopupComponent, use the following code:

constructor(@Inject(MAT_DIALOG_DATA) public _userData: any) {}

The variable _userData will hold the details of the user.
