Hi folks
In the documentation page explaining customisation...
It states the following:
"If you want to tweak the code you can do so in one of two ways:
By following the Radzen extensibility rules and writing your custom code in the provided extensibility hooks listed later in this article."
I can't find any such rules or hooks, can you hook me up to the current rule book documentation please. 
Many thanks
Mark.
Hi Mark,
All pages, shared layout, services, etc are partial classes and you can extend them.
Best Regards,
Vladimir
I figured that was the case but the documentation teased that there was something else to follow.
I guess I am missing something. What am I doing wrong here.
I create a new application, then a single blank page, add a button, then right click and open the .cs in VS Code. I extend the partial class by adding a namespace and my code. I allow Radzen to spot the changes and restart/build etc.
Why doesn't it appear as an 'Invoke method' in dropdown for the 'onclick' event of a button on the same page?
What are the 'rules' to apply to this kind of hooking in or am I getting the wrong end of the stick here?
The code below is just an example, I know I can use the notification dropdown, that is not my point. I want to know how to fire off some async code from a button using the invoke dropdown in a way that my code doesn't get overwritten.
I asked a similar question here: Invoke custom methods
Cheers
Mark.

using Radzen;
using Radzen.Blazor;
using Microsoft.AspNetCore.Components.Web;
namespace Radzen3.Pages
{
public partial class HomeComponent
{
public async void Button0ClickV2(MouseEventArgs args)
{
NotificationService.Notify(NotificationSeverity.Error, $"Button clicked", $"This was from Button0ClickV2", 1500);
}
}
}
Your code looks fine and the exact same method was displayed successfully when I tested it:
If the problem persists you can zip your app and send it to info@radzen.com. Just make sure to delete the server\bin and server\obj directories to keep the zip size small.
I gave up but revisited after the weekend and it worked without making any changes to the project or code.
Only thing that I can think happened was that Radzen was restarted and maybe the code was regenerated.
Time to start re-evaluating again, thanks for your help!
Mark.
