The control works well and is as configurable as you need. There is nothing we wanted to do that required a workaround on our part. There are a lot of nice touches that show maturity.
I have to say RadiantQ’s dev and support turnaround is some of the best we have ever experienced. The samples you provide are very comprehensive and much more accessible than many I have tried lately (others have a “framework” and look cool but are hard to dig through, or only touch on a few features). They show a lot of thought, from a developer’s perspective.
And the User Guide is a primo piece of work, very useful and also something lacking in a number of other companies’ products.
We also very much appreciated the fast turnaround for enhancements and fixes. In one case, we asked for a particular feature on a Friday, and there was a new version in my inbox the next morning. It was literally done overnight!
