Attempting to locate a method to update information post-editing or deletion in angular

Are there any methods similar to notifyDataSetChange() in Android Studio, or functions with similar capabilities?

Answer №1

First approach: It seems that you are utilizing the mat-table, and triggering a refresh method upon successful edit/delete calls.

import { MatTableDataSource } from '@angular/material/table';

//...

dataSource = new MatTableDataSource<MyDataType>();

//...

refresh() {
  this.myService.doSomething().subscribe((data: MyDataType[]) => {
    this.dataSource.data = data;
  }
} 

Second option: Another way to refresh the data is by using ChangeDetectorRef.

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

//...

constructor(private changeDetectorRefs: ChangeDetectorRef) { }

//...

refresh() {
  this.myService.doSomething().subscribe((data: MyDataType[]) => {
   this.dataSource.data = data;
   this.changeDetectorRefs.detectChanges();
  }
}
