reset paginator first page angular material

Question

I am trying to go to the first page of the mat-paginator, that is, reset the pagination, but it does not work. Any idea how it can be solved?

My html is such that

<mat-paginator [length]="itemTotal" [pageIndex]="page" [pageSize]="itemPage" (page)="pageEvent = getPublicationFollowersData($event)">
    </mat-paginator>

The typescript:

   getPublicationFollowersData(event?: PageEvent) {
      this.getPublicationsUser(event.pageIndex);
}

and i try to initialize the page with:

this.page = 1

But it does not work.

Answer 1

You need to use a ViewChild decorator to select the paginator and then set the pageIndex property of the paginator.

@ViewChild() paginator: MatPaginator;
...
this.paginator.pageIndex = 0;

Edit: As suggested by the other answers, if you would like to reset the paginator to the first page, it would be better to use this.paginator.firstPage()

Answer 2

<mat-paginator #paginator [length]="length"
               [pageSize]="pageSize"
               [pageSizeOptions]="pageSizeOptions"
               (page)="pageEvent = paginationClicked($event)">
</mat-paginator>
@ViewChild('paginator') paginator: MatPaginator;
this.paginator.firstPage();
