Using the DialogService & RadzenDialog components, when presenting a dialog with a dropdown we're getting this error:
Radzen.Blazor.js is loaded with a 200 response. I can't find
preventArrows anywhere in the codebase
Unhandled exception rendering component: Could not find 'preventArrows' in 'window.Radzen'.
Error: Could not find 'preventArrows' in 'window.Radzen'.

Make sure you've included the script for Radzen.Blazor:

It is being loaded with a 200 response code, all of the rest of the controls are working; grids, inline edit etc.
Same happening for me when I update NuGet package to the newer versions. On 2.12.1 version everything working fine, but with like 2.15.3 I get this error message too when I'm using the new Confirm Dialog component and I also trigger it with a dropdown change event (not 100% that is the problem, but for start is good to know, and the script include is also works perfectly). I hope I found a workaround or a fix because I need newer version of the NuGet package where the dropdown autofocus is fixed.

Try to clear your browser cache
Seems like working with cache clear, but now I can open all my disabled dropdown and select the item (and no exception), probably a new bug, yet I don't know its just only for me.

This is something new - fix will be published tomorrow
Okey, Thanks for your help!
Edited: Sorry my mistake...ignore this

I get the same error even when I am not interacting with application.
I get this error with anything that's not text or numeric. For example, Drop downs:
<RadzenDataGridColumn TItem="Puppy_Trick" Property="TrainerName" Title="Trainer">
<RadzenDropDown TValue="int" Data=@Trainers TextProperty="TrainerName"
Clearing the browser cache did not work for me.
