The following is a series of posts I made on my old blog regarding control suites. I think it should be an interesting read for anyone evaluating a 3rd party control suite. Be sure to read both posts.

The Honeymoon Is Over: My Farewell to 3rd Party Controls
Over the last couple of years I have used web controls suite from Infragistics and Telerik.
I was a very enthusiastic user, and I think that I could have been a
product evangelistic for Telerik about 9 months ago. Telerik seems to
have an especially agressive development cycle and they deliver new
products every couple of months.
So what happened?
Well, the whiz-bang wore off and I began to realize the following deficits:
- Inadequate Documentation.
3rd party never seem to be documented well. Sure, there's lot of
documentation for both Infragistrics and Telerik, but that doesn't mean
it's good documentation. I can't come down on them too hard. My wife is
a tech writer and I understand the difficulties of writing good
documentation. However, I can never seem to find what I need. Which
leads to the next problem...
- Inconsistent API's.
I personally try to follow Microsoft's guidlines and examples. I want a
.NET developer reviewing my code to feel "at home", like my code is a
natural part of the framework itself. Now, I understand that 3rd
parties may have excellent reasons for establishing their own feel.
However, both API's are inconsistent even within themselves. Don't
expect methods that do the same thing on different controls to have the
same name. I feel like I have to become an expert with each and every
control.
- Bulk. Too many features. Does that
sound backwards? I spend a lot of my time figuring out how to minimize
what the control does. Take Telerik's rich text editor; it rivals Word.
Additionally, the acutal HTML rendered for many of these controls is
expansive. I've ended up writing a number of simple controls,with
simple output just because using a 3rd party control seemed excessive.
I
will say a positive thing about 3rd party controls. If you have a
relativity simple application to development, and you want very rich
client functionality, these suites will benefit you. However, if you
are writing commericial applications for a wide audience, and if
performance is an issue, then I would recommend being a bit more wary.

Telerik Responds
I was surprised and somewhat humbled last week to receive an email from
the CEO of Telerik, Vassil Terziev. He had come across my blog post where I criticize 3rd party control suites and wanted to respond.
To
summarize, he was very cordial and acknowledged each of my complaints
as valid. He explained that Telerik has recently changed a few things
about their development cycle in order to improve upon the weaknesses I
listed. He also pointed out a few things Telerik has already
accomplished to those ends (such as a 70% reduction in output from
their tabstrip product).
His email was personal, friendly, and
transparent about his products. I was very impressed and the fact that
Telerik has that kind of leadership encourages me to give their
products another chance.
Luckily, my employer's subscription to
their control suite still has many months left. Expect me to post my
reflections upon the updated Telerik products when they arrive.

I never did get around to really evaluating the improvements that Vassil listed. We did continue to use there controls and I have continued to be impressed with their attention to customer input. I have had some performance issues with the rich text editor, though mostly in an environment with multiple instances of the editor on a single page.
