Angular Material mat-datepicker (change) event and format

Question

I am using angular material datepicker directive and I have few problems.

1. When I open date picker dialog and select any date, date shows up in input text box, but I want to call a function when ever any change occur in input text box.

Right now if I manually enter any value in input text box, I am triggering function using (input) directive and it is working fine as shown in code. I want to trigger same function when date gets change using date picker dialog.

2. I also want to change the format of date from mm/dd/yyyy to dd/mm/yyyy when selected from date picker dialog. Here mm/dd/yyyy is set by default in this directive.

<input matInput [matDatepicker]="organizationValue" formControlName="organizationValue" (input)="orgValueChange(i)">
<mat-datepicker-toggle matSuffix [for]="organizationValue"></mat-datepicker-toggle>                 
<mat-datepicker #organizationValue></mat-datepicker>

Answer 1

from docs you can use one of the below events based on your requirement

@Output()
dateChange(): EventEmitter<MatDatepickerInputEvent<D>>

Emits when a change event is fired on this .

@Output()
dateInput(): EventEmitter<MatDatepickerInputEvent<D>>

Emits when an input event is fired on this .

For example:

<input matInput #ref [matDatepicker]="organizationValue" formControlName="organizationValue" (dateChange)="orgValueChange(ref.value)">

or

 <input matInput #ref [matDatepicker]="organizationValue" formControlName="organizationValue" (dateInput)="orgValueChange(ref.value)">
