'Sorting not getting happened in angular material
I'm trying to add the sorting feature for the mat-table with angular material. I had got the hand cursor over my columns, When I clicked I'm unable to see it's action. i had added the attribute "matsort" to the table level & "mat-sort-header" for the mat-header-cell selector. 2) Secondly, I'm not able to view my "Actions" columnn for edit and delete. The following is my code :
app-component.html :
<mat-table [dataSource]="emplist" matSort>
<ng-container matColumnDef="Emp_Id">
<mat-header-cell *matHeaderCellDef mat-sort-header> ID </mat-header-cell>
<mat-cell *matCellDef="let data"> {{data.Emp_Id}} </mat-cell>
</ng-container>
<ng-container matColumnDef="Emp_Name">
<mat-header-cell *matHeaderCellDef mat-sort-header> Name </mat-header-cell>
<mat-cell *matCellDef="let data"> {{data.Emp_Name}} </mat-cell>
</ng-container>
<ng-container matColumnDef="Emp_Gender">
<mat-header-cell *matHeaderCellDef mat-sort-header> Gender </mat-header-cell>
<mat-cell *matCellDef="let data"> {{data.Emp_Gender | settingGender}} </mat-cell>
</ng-container>
<ng-container matColumnDef="Emp_Deptname">
<mat-header-cell *matHeaderCellDef mat-sort-header> Department </mat-header-cell>
<mat-cell *matCellDef="let data"> {{data.Emp_Deptname}} </mat-cell>
</ng-container>
<ng-container matColumnDef="Emp_Salary">
<mat-header-cell *matHeaderCellDef mat-sort-header> Salary </mat-header-cell>
<mat-cell *matCellDef="let data"> {{data.Emp_Salary}} </mat-cell>
</ng-container>
<ng-container matColumnDef="action">
<mat-header-cell *matHeaderCellDef> Actions </mat-header-cell>
<mat-cell *matCellDef="let data">
<button mat-button color="primary" (click)="EditEmployee(data.Emp_Id)">Edit</button>
<button mat-button color="warn" (click)="DeleteEmployee(data.Emp_Id)">Delete</button>
</mat-cell>
</ng-container>
<mat-header-row *matHeaderRowDef="columndefs"></mat-header-row>
<mat-row *matRowDef="let row; columns: columndefs;"></mat-row>
<!-- <mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator> -->
</mat-table>
app-component.ts :
import { Component, OnInit, ViewChild } from '@angular/core';
import { EmployeeinfoService } from './employeeinfo.service';
import { FormBuilder, FormGroup, FormControl,Validators } from '@angular/forms';
import {Sort,MatSort} from '@angular/material/sort';
import { Employee } from './employee';
import {MatTableDataSource} from '@angular/material/table';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
columndefs : any[] = ['Emp_Id','Emp_Name',"Emp_Gender","Emp_Deptname","Emp_Salary"];
@ViewChild(MatSort) sort: MatSort;
title = 'HttpClient';
emplist : any;
deptlist :any;
myform : FormGroup;
result : string;
submitted : boolean = false;
btntxt : string = "Create";
public dataSource = new MatTableDataSource<Employee>();
//constructor
constructor(public serviceref : EmployeeinfoService, frmbldr : FormBuilder){
this.myform = frmbldr.group({
Emp_Name : new FormControl("",Validators.required),
Emp_Gender : new FormControl("",Validators.required),
Emp_Deptno : new FormControl("",Validators.required),
Emp_Salary : new FormControl("",Validators.required),
})
}
//ngOnInit
ngOnInit(){
this.dataSource.sort = this.sort;
//Get Employees:
this.GetEmployeesData();
}
}
Currently, I'm able to view the data and columns with sort effect on mouseover, but the sorting is not getting happend

Mb try put sort after this.dataSource = new MatTableDataSource('data'); //geted data from request or another source! this.dataSource.sort = this.sort;
