Aspnetcore: Passing arguments to onclick

Created on 4 Jun 2018 · 8Comments · Source: dotnet/aspnetcore

Not sure if this is doable in 0.3.0, but I want to pass arguments to my onclick method like so:

button onclick=@MyMethod(MyParam)

Doing so results in a compile error of "CS 1503 cannot convert from 'void' to 'string'"

Thanks guys! Side note: So happy you guys are responding so quickly to help requests, but is there a better spot for these? I feel guilty opening issues when they aren't really _issues_ :P

@alexanderjwoods https://gitter.im/aspnet/Blazor is a quite active place 😉

@alexanderjwoods You can also post questions on StackOverflow. That way they can be referenced over time

@Suchiman Awesome! I will post over there unless it is a real bug!
@danroth27 I refuse to post on SO because of their attitude toward beginners. I have had more than one intern tell me they don't like SO because of the condescending nature toward "n00b" questions, and I quite agree. It turns people off to programming at worst, and at best it makes it harder for people to become proficient!

Fair enough. I think you'll find the folks on the Blazor Gitter to be very helpful.
