These three errors occur on random basis in the REPL tool inside the Telerik UI for Blazor documentation:
Possible workarounds include:
REPL for aspnet core notifications is broken, it runs on first load and then fails to do anything if I change even a single character and then try to run it again
ASP.NET Core REPL - ASP.NET Core Components Playground & Testing - Telerik
Not sure that link will work but I'm talking about the notification that shows email message, error message and upload success
I'm seeing message in dev tools about 'isMobile is not defined'
Running in Windows 10, latest version of Edge OR latest version of Chrome
The Basic Usage Demo of the DataSource does not run in REPL.
I included a nuget package, but the code will not compile because it can't find the package symbols.
For example:
https://blazorrepl.telerik.com/cbPPOzcQ05pZuq4a09
From this page: Hierarchy in ASP.NET Core Grid Component Demo | Telerik UI for ASP.NET Core
Edit it REPL
Run, works fine
Make a simple change like changing height to 500px
Run, gives a blank screen on right side.
