We use their controls all the time in our web site. Their controls are vastly superior to the built-in controls and allow us to support using them in anything from basic to complex scenarios. They are highly customizable as well. We also appreciate that they continue to support a legacy technology like ASP.NET Web Forms. Review collected by and hosted on G2.com.

My team used Telerik UI for ASP.NET Core to build a vendor management portal for tracking vendor performance and managing payments.

Also it's build in authentication and role management simplified user permission to great extent. Review collected by and hosted on G2.com.
