you need a material design version. While MatBlazor has a slider, there are dozens of standalone sliders.
you can also look at the MatBlazor source code their slider and see how they hookup events.
note: I'd never use Blazor (I prefer react.js), just interested in the implementation, so can not comment on the quality of MatBlazor.
