@ViewChild/@ViewChildren in Angular (Tutorial 35)

@ViewChild/@ViewChildren decorator provides us with a easy and simple way to access and manipulate the properties and methods of a Child Component from a container or root component.
By using @viewchild we can achieve the following things,
• Accessing template of same component
• Accessing the template of child component
The @ViewChild query returns the first matching element from the DOM and updates the component variable on which we apply it.
we must supply the query selector, which can be a string or a type as the first argument to the ViewChild

such a wonderful explanation...

Thanks 😊

[@adarshdwivedi5395]

[@neelamvishvakarma3609]

Amazing Explanation in very easy words. hats off to you . such a great tutorial.

[@NishaSingla]

Thank you so much for your comment 😀😀👍🏻

[@coradragut4505]

Finally really understanding these concepts and where everything is supposed to go and how it gets accessed. After countless of tutorials, articles and Maximilian's Schwarzmuller's famous Udemy course put on repeat for these concepts (he does NOT know how to properly explain concepts), you are like a breath of fresh air! Thank you! Going to check out if you also explain the ContentChild concept as well. have an amazing day Nisha! :)

[@NishaSingla]

Really glad to know that you finally got what you were looking for ..

Yes I too agree with Cora..Max famous course is not at all digestive for freshers like me ..He never explains basic concepts properly 👀😅..Thanks to you as finally after wasting 2 days I understood some important concepts!! I'm super excited to learn angular from your videos now!!

[@maheshshirsat9075]

checkout procademy utube channel for angular hes great for freshers

[@rickmemmer5625]

I couldn't agree more about Nisha -- and I knew she was different inside of 60 seconds of this video. I was working on an exercise that went through the "Difference between Template-Driven and Reactive Forms in Angular" -- and I was running into some compilation errors. One of them involved @ViewChild -- and it was a blessing in disguise because that issue led me here.
As for Maximilian, through immense experience -- my advice would be to never get too hung up on a particular teacher (regardless of reputation). I'm not commenting one way or the other on his courses -- I'm simply saying that if you find yourself repeating the instruction, find someone else who works better for you. I'm sure you know that now, but I wanted to mention it anyway.
For example: I was watching an excellent Udemy course on OOP in C#. The course is great for what it is -- but it doesn't dive into detail (which is fine because it wasn't designed that way). But I had a couple of questions along the way -- where I wanted more detail. That led me to this guy (who blew my mind -- once again, inside of 60 seconds).
PART 1: Constructors in C#.NET Part 1 | C#.NET Tutorial | Mr. Bangar Raju.
That guy dives into detail like nothing I've ever seen -- and he makes every second count. Moreover, by the end of each video -- I understood everything he explained (which is incredibly rare for complexity at that level -- for me, anyway). Once again, that's not a knock on other instructors -- as their instruction is obviously working for some people. And of course, I'm not saying we shouldn't be critical of instructors -- I'm just saying that it often comes down to just finding the right ones for you.
Speaking of which: I already have plenty of good resources on Angular, but I feel quite fortunate to have found Nisha -- as she set herself apart right out of the gate. Gotta love how that works: The frustration of resolving compilation issues and digging deeper to understand -- led me someone who can help me better understand.

[@codewithme172]

@@akd2487 Probally that guy does not fully understand the concepts...otherwise he can explain it clearly!

[@vasanthapandiyanm2405]

great Nisha... more thanks for this video.... kindly do video for headers and interceptor concept...

[@chaka1530]

Just a small additional note. Instead of putting ref to a child component we could just put this in our .ts file ->
*@ViewChild(CounterComponent) child: CounterComponent* instead of *@ViewChild('childView) child: CounterComponent*
In this way we are omitting the usage of ref in .html file. Btw, video is super helpful and clear. Thanks :)

Hey thanks for your suggestion.. Appreciate 👍🏻👍🏻😊😊
