I have verified both the options. Unfortunately, I wasn't able to a figure where the wrong value is in the "Customize theme" section, but I managed to fix this in the app.json file. After fixing the "$slider-handle-background-color issues, the Material Theme CSS file was fully updated.
When I ran our application with the updated css, the entire application is affected. Here are few of the observations:
Data not visible until it's hovered in datagrid
No selection of page in navigate panel
Font Size of the buttons are bigger
Datagrid navigation are bigger
Basically, the pages in the application look different than what it used to be.
Could you please advise on how we proceed with this? Fixing this on our side could be a significant effort. (Which I prefer not to do)
I’m still not sure about the issues you’ve reported.
There are intentional visual changes in our 4.x themes listed in the thread I’ve linked and that’s why the major part of the version is raised. If you don’t like the new version of the themes you can keep the 3.x version of Radzen.Blazor.
There are parts of what you are reporting that is not how the theme works/look:
