The Basic Usage Demo of the DataSource does not run in REPL.

1. Run the demo https://demos.telerik.com/aspnet-core/datasource
2. Only the headers are displayed

This sample seems to be broken.  It won't run.

I included a nuget package, but the code will not compile because it can't find the package symbols.

For example:

Edit it REPL

Run, works fine

Make a simple change like changing height to 500px

Run, gives a blank screen on right side.
