I try to create a component which includes two dataTables each of it with another dataSource. My Tables aren't visible right after the component is loaded because of my *ngIf
so that i couldn't use ngAfterViewInit()
instead i'm using a solution a user pointed out on Github:
private paginator: MatPaginator;
private reportingPaginator: MatPaginator;
private sort: MatSort;
private reportingSort: MatSort;
@ViewChild(MatSort) set matSort(ms: MatSort) {
this.sort = ms;
this.reportingSort = ms;
this.setDataSourceAttributes();
}
@ViewChild(MatPaginator) set matPaginator(mp: MatPaginator) {
this.paginator = mp;
this.reportingPaginator = mp;
this.setDataSourceAttributes();
}
setDataSourceAttributes() {
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
this.reportingDataSource.paginator = this.reportingPaginator;
this.reportingDataSource.sort = this.reportingSort;
}
But i still can't get it to work. My Pagination doesn't work, when both paginators are included into the @ViewChild(MatPaginator)
. If i only include one of the paginators
@ViewChild(MatPaginator) set matPaginator(mp: MatPaginator) {
this.reportingPaginator = mp;
this.setDataSourceAttributes();
}
or
@ViewChild(MatPaginator) set matPaginator(mp: MatPaginator) {
this.paginator = mp;
this.setDataSourceAttributes();
}
the one i included works fine! So what do i need to do to get both paginators work?
For mutiple MatPaginator and MatSort components present in single page you need yo use
@ViewChildren(MatPaginator) paginator = new QueryList<MatPaginator>();
@ViewChildren(MatSort) sort = new QueryList<MatSort>();
in your code which will return you list of MatSort and MatPaginator defined in the order in which it is present int your page. Below is the complete implemetation
import { Component, OnInit, ViewChild, ViewChildren, AfterViewInit, QueryList } from '@angular/core';
import { MatTableDataSource, MatSort, MatPaginator } from '@angular/material';
export interface AssignmentElement {
assignmentId: number;
action: string;
userName: string;
roleName: string;
enabled: string;
createdOn: string;
createdBy: string;
modifiedOn: string;
modifiedBy: string;
status: string;
}
export interface RoleElement {
roleId: number;
action: string;
roleName: string;
roleDescription: string;
createdOn: string;
createdBy: string;
modifiedOn: string;
modifiedBy: string;
status: string;
}
export const ASSIGNMENT_ELEMENT_DATA: AssignmentElement[] = [
