What is causing Mag Pagination and Mag Sort to malfunction?

Struggling to incorporate pagination and sorting in the frontend after retrieving data from nodejs. Trying to follow a guide per this link: here

While attempting to apply a similar logic, there seems to be an issue as it's not functioning correctly. Here is the TypeScript file:

import ... // Code snippet here 

and the HTML file:

<div id="#main-body">
  <!-- HTML markup here -->
</div>

And the SCSS:

#main-body {
  padding-top: 20px;
}

... // SCSS styles continue

My approach involves fetching all the data during ngOnInit(), then applying sorting and pagination during ngAfterViewInit(). However, the functionality is not working as expected. The webpage shows sorting arrows but clicking on them doesn't trigger any action, and the pagination buttons are visible but non-functional. Here is a screenshot of the current webpage: https://i.sstatic.net/xo0S2.png

Answer №1

It is not advisable to perform this operation within the getAllTicket method as it will remove the paginator and sorting that were just applied to the data source.

this.dataSource = new MatTableDataSource(this.ticketList)

Instead, initialize the object at the beginning like this:

dataSource = new MatTableDataSource<Ticket>();

In the getAllTickets method, simply set the data:

this.dataSource.data = this.ticketList;

Furthermore, ensure that your matSort static property is set to false:

@ViewChild(MatSort, { static: false })
