I have to strongly disagree. I have used their Sliverlight components in every SL project I have been involved with for the last four years and I could`t live without them. They are professional components for enterprise which does something that a open-source project could seldom( maybe never) do, support all the odd-cases needed. These are all the weird cases that no one would bother to implement in an OS-project, since it`s very seldom needed, but since they know that their customers might need this functionally they have already implemented it. Just look at the feature list for their GridView component for SL and try to match that with an OS-project. Combining this with good support and you got a winner.

As a result the good experiences I had with their components in a SL context I am know adopting their KendoUI components together with ReactJs. So far all the points made above for SL still stands for KendoUI.

Try Infragistics, you will never look back.

Both Telerik and Infragistics have their main development offices in Sofia, Bulgaria. From what I've heard most of Infragististics developers/testers/managers have worked for Telerik in the past and there is a considerable current in the other direction as well. I wouldn't expect a massive difference in the quality.

Could you give me some examples of why you switched to Infragistics and never looked back. And also some info on which platforms you have used it on?

What is the benefit of using KendoUI over any of the free JS options available? Edge cases again?

[andwaal]

Lets do an example. In many of the enterprise applications I work on large datagrids are used. I did a loot of research in order to find the best open alternative, from what I found this seems to be http://datatables.net/ . It seems like a great product with a lots of features, plugins and ways to tweak it. But still KendoUI`s got features like proper grouping, binding to remote data(filtering, sorting, grouping etc), advanced filtering, fast customisation of headers/rows/cells, proper select/multi-select and so on. Im aware that you could probably do all these things with Datatables, but still you would have to find the appropriate plugins, browse through bad documentations and properly end up implementing half of the missing features your self. Of course this could be done, but with KendoUI you got it all out of the box, with proper documentation. And if you don`t figure it out, you got professional support with fast response(great for junior dev). Yes KendoUi got a steep licence cost, but it don`t take long to realize that it`s worth it. I could to exactly the same example for the TreeView component(and to some degree the Data Visualization package, though the open alternatives seems much more competitive, if not better, here).

So to answer your question, from my experience using KendoUI reduces the time needed for the average developer to complete the task.

Thanks for the "OS" rant. You should use the proper term, Free Software, next time: https://www.gnu.org/philosophy/open-source-misses-the-point....

[andwaal]

Your absolutely right. Free Software was the term is was referring to. And if it came out as a rant that was not my purpose at all, but to share a positive experience about Telerik`s products.
