The company I work at bought Telerik Kendo UI and we've been using it for a couple of months now. After spending many weeks working with this product, I'm curious to take a read on how other people feel about it. Note I've only ever used Bootstrap, Ionic, and other open source frameworks prior to this.
From what I can tell:
Pros:
Builds awesome UI with very minimal design effort
Works incredibly well with entity framework back end
Handles data view related logic internally and requires minimal effort
Cons:
Obfuscated source code due to not being open source, means it's impossible to figure out what the hell it's doing
Workarounds are a pain in the ass
They do horribly sadistic things to markup and CSS
Documentation is terrible, often omitting example code, or contextual code
So all that said, how do you guys feel about Kendo UI?
