Hello Siva , Yes you can acheive this using @output decorator in angular. let me give you small example: @Output ddValue=new EventEmitter() OnChnageEvent($event){ this.ddValue.emit($event.target.value); } and in your parent component you can get the value in the method if you want full example then just send a reply i will share Thank you

There are multiple ways to resolve this issue: 1. Using the output: You could use the Output decorator to create an evenemitter which will emit everytime someone changes the dropdown value. For more information: https://angular.io/guide/inputs-outputs#sending-data-to-a-parent-component 2. You could create an RxJS Subject which will emit each time someone changes the values and will pass the dropdown value via next method. And component where you want to access this data will subscribe to this subject. https://jasonwatmore.com/post/2019/02/07/angular-7-communicating-between-components-with-observable-subject
