Telerik's products and support are quite good. They have a large suite of controls that we use and when you engage their support, you don't have to wait too long for a response. They have extensive documentation, so it is relatively easy to get started and to add controls you may not have used in the past in an existing project. I really like the fact that their support often creates sample projects for you to test out their solution to your problem. Review collected by and hosted on G2.com.

Like most things, if you want something very out-of-the-box, it can be hit or miss. Sometimes, Telerik has the solution and engaging their support early-on has been very beneficial. Other times, it is a known issue or limitation, and you can tell it is not likely to be fixed in the near future. It is disappointing to get that news, but at least their support is very responsive and lets you know quite quickly. Sometimes they have a control that you find really useful but unfortunately it is not used by many and so does not get the attention you would like (in terms of making it better and easier to integrate into your project).

The ease of use in terms of their controls and tools. They also tend to have very realistic examples that can be applied to real-world situations. I also like the technical support over the years. Review collected by and hosted on G2.com.

They have a lot of tools and suites of tools. It can be confusing to know which bundle or bundles to choose. Review collected by and hosted on G2.com.

thethe vastness of available controls and the quantity of guides and examples to view both for web forms and for the ASP part Review collected by and hosted on G2.com.

The first disadvantage for users is the price of the suite. For a developer working alone, it's a bit high. Review collected by and hosted on G2.com.

Kendo provides a wide range of flexible components available across the most popular web frameworks, and they integrate seamlessly into our Vue 3 applications. Whenever I’ve run into issues and reached out to customer support, they’ve been quick to respond within the promised timeframe and provided clear, helpful solutions. Review collected by and hosted on G2.com.

My biggest issue with Kendo-Vue right now is the broken event type support. As a TypeScript user, I’m not a fan of being forced into using a generic catch-all for event handlers. The documentation also feels crowded and difficult to navigate, with examples that are often too basic to cover real-world scenarios. Additionally, the website could use a refresh — the layout feels bulky, the fonts are oversized, and the high-contrast color scheme (dark blue/white/red) is a bit straining on the eyes.

The vast amount of great controls. Telerik is easy to integrate and use. Support is fast and able to help. Review collected by and hosted on G2.com.

Sometimes even simple adjustments or additions in components take long to implement or are not implemented at all, even when there are various votes or missing key functionality. Review collected by and hosted on G2.com.

I like how easy and shorter it makes for me to do simple code Review collected by and hosted on G2.com.

I dislike the help articles on the website. I need more visual examples and code. Especially for first time user, I feel like the documentation needs a lot of improvement to help me incorporate Telerik into my code. Review collected by and hosted on G2.com.

The documentation is clear, and it makes it easy to learn how to use the components. Review collected by and hosted on G2.com.

The ability to troubleshoot errors and resolve compatibility issues is a key benefit. Review collected by and hosted on G2.com.

Telerik Reporting abstracts away pdf management and offers many options for report generation and rendering. They're also quick to respond to questions through their support portal and offer useful assistance. I recommend using the standalone designer tool over the visual studio integration option as it's a lot less buggy. Review collected by and hosted on G2.com.

Setup for Reporting can be cumbersome and feels a bit too complicated, especially designing reports by linking them to classes in assemblies, and setting up the ReportsController to work as required. While it can work out of the box by following default settings, if something doesn't work, it can be hard to pinpoint what's wrong. Fortunately Telerik Support is generally handy for cases like that. Reporting items for tables need a bit more documentation on how chaining items inside works. Review collected by and hosted on G2.com.

For those that need a better set of controls than the out of the box Visual Studio ASP.Net Ajax controls, the Telerik controls provide a mature and consistent set of controls that perform well in production and consumer facing web applications.

The controls are easy to implement and in some cases can be directly swapped for the equivalent Visual Studio controls. This allows for ease of integration when converting from older web controls.

I've used more advanced features and had my share of interesting things that I didn't understand when trying to get controls to do what I want. In these cases, I've created support tickets as part of my subscription and found them to be tremendously insightful and helpful. They somehow seem to be able to read our minds in some cases. Review collected by and hosted on G2.com.

Some of the things I dislike about the ASP.Net Ajax controls are:

The lack of a full-fledged style manager. Telerik as some basic style manager features that can be loaded in but it is quite limited compared to their other products.

Poor documentation quality. While this has improved over the years, the javascript api is quite limited to the point of just being a list of methods without any context in how to use the properties and methods in more complex cases. Review collected by and hosted on G2.com.

What I really appreciate about Progress Telerik is how much easier it makes my daily work as a developer. Their tools—especially the UI components—are intuitive and save me a ton of time when building more complex applications. I also like how smoothly everything integrates across different frameworks, which helps me stay focused on the actual development rather than dealing with compatibility issues. The documentation is clear and helpful, and when I’ve had to reach out to their support team, they’ve always been quick and spot-on with their answers. All in all, it’s a solid toolkit that I’ve come to rely on, and it keeps getting better with each update. Review collected by and hosted on G2.com.

There isn’t much I’d really call a downside with Progress Telerik, but if I had to mention something, it would be the cost—especially for freelancers or small businesses. The tools are excellent, no doubt about it, but the pricing can be a bit of a stretch if you're working with a tighter budget. Also, a few of the more advanced features can take some time to get the hang of, especially if you’re new to the ecosystem. That said, once you’re up and running, the overall value and the quality of support do make it feel like money well spent. Review collected by and hosted on G2.com.
