Error TS2339: The member 'sort' is not found in the type 'BehaviorSubject<AbstractControl[]>'

Looking to create a dynamic table using Angular material where I can dynamically add or remove data. As a newcomer to Angular, I found the following StackBlitz helpful in setting up the table:

https://stackblitz.com/edit/angular-material-editable-table-fazhbc

While most of my changes have worked as expected, I am encountering an issue with sorting the data. Here is the code snippet causing the error:

 ngAfterViewInit() {
    this.dataSource.sort = this.matSort;
  }

The error message I receive is: TS2339: Property 'sort' does not exist on type

'BehaviorSubject<AbstractControl[]

. Is sorting not supported in the material table data source, or am I overlooking something?

Answer №1

To retrieve the present value from the BehaviorSubject, you can use either value or getValue(). Once obtained, you can then proceed to sort it using the following syntax:

this.dataSource.value.sort(this.matSort)

.

Since BehaviorSubject returns an observable, it is necessary to subscribe to the data first and then apply the sort function.

Imagine a scenario where a news reporter is delivering the latest updates on TV, similar to how the Behaviour Subject passes on the most recent data.

To implement this concept, create a service named myService and include the following code: public myData: BehaviorSubject = new BehaviorSubject([]); updateData(data): void { this.myData.next(data); }

Then, whenever you need to transmit data, call the updateData method like this: this.myService.updateData("Test"); You can pass various types of data such as objects or arrays. In another component where you want to receive this data, add the following code: this.myService.myData.subscribe((data) => { console.log(data); }); This will display the received data. You can incorporate the above lines in any component where data is required.
