2-way communication between components in blazor is so much better than in react..
I don't think I'm ever gonna be using React again, lol

Hi guys,

I am exactly following the tutorial from the beginning to 8:31 but I failed to make childText change from "nothing" to "Say Hi" after clicking the button. Have anyone had this problem and solved it? I am using .NET 8.0. Thank you in advanced

Great content! As .NET developer, rather Blazor. Congratz!

This is helpful, but how would the parent communicate "down" to child? Also, how could a child use the parent to relay a message to a sibling without going the service and message/subscriber route?

Great choice of names! The last of us is wonderful!

Excellent explaination of the topics. I've used all the methods explained in the video before but never the Service/state combo but already found examples where this could come in handy. Thank you for sharing.

Hey Patrick, have you ever done videos that focus on the nuts and bolts around the service/state in blazor? You touched a lot of topics in the last min or so on services and I'd love to know more about it 😜

Thanks a lot! I was really looking for this, needed to close a modal on a parent component from its child, this worked like a charm!

Hello, can anyone direct me to where I can see an example of someone transporting information from dynamically created components to the parent component. I am going to experiment using the message service described here but I was wondering if there was a confirmed way to do it or a way via event call backs etc. The catch is there is going to be multiple dynamically created components and some of them are the same type.
