Glad it was helpful!
Thank you for providing the github repository
I hope it helps. 😉
Hey im trying to pass in a complex Object List in my razor component and when running my application I get Blazor server error usung chrome. Would you habe any idea as to why this is occurring?
What is the error?
Hi, I tried doing this with but when it hit the page. the generated value got ran twice by itself.
For example, I hit the page the shown var was 22 then a few miliseconds it changed to 67. How do I prevent it from running again?
I'm on .net 8.0.1
It depends on how you initialize the value. OnInitialiezed or OnInizializedAsync are good locations. Hard to tell your issue without seeing your code.
@@ClaudioBernasconi Ah, figured it out. It was prerender. I need to change render mode to render-mode="WebAssembly"
Hi, I am up to 3:30, but when I click the "Generate" button, the number does not change
That is not okay. However, it's hard to help you like that, I'm sorry. I hope you'll find a solution.
Did you ever fix this issue? This seems to be my problem with every tutorial
EDIT: The reason you get this issue is because your _Imports.razor does not yet exist if you're following along at 3:32... if u look closely, _Imports.razor appears on the right side in the video but its not talked about until afterwards which might be where your confusion comes from, once you add this file it will update
Using Sessions in a MVC core application, how to use the user session values in a Blazor component inside MVC view?
Great question. I'm not familiar with how Sessions work in MVC. However, that shouldn't be an issue. The concept is simple. You have to provide every information you want to use inside a Blazor component as an argument.
There are more advanced concepts but I would keep it simple and provide the information from the Session as an argument (parameter) to the Blazor component.
Say you want to use the username, you add a parameter using the [Parameter] attribute on the Blazor component and then provide it when you use the component.
@@ClaudioBernasconi thanks for the response. In my case I would like to use some existing mvc services (scope implementation) that uses IhttpcontextAccesor to get de user session values and retrieve information from database. However I saw in the Microsoft documentation that is not recommend to use the HttpContext in blazor server
Does this work on .net 7 as well ? Sry im new..
Thanks for your question, and welcome. Yes, it should also work on .NET 7.
Thanks, but it wouldn't be easier to use Blazor Custom Elements
I haven't explored custom elements in Blazor yet.
