I don't know where to start, Marin. I like you. I have read your blog posts before. But your comments here do not help the issue at hand, nor do they reduce my frustration.
First off, for some reason you and Nencho are harping on a single thing I said regarding buggy code and are spending a great deal of time defending it. For the record, I am a software developer. I am familiar with bugs and am aware that having them is not some sort of sign of complete incompetence. But mentioning how much time and resources you guys spend fixing bugs is not an indicator of quality. Quite the opposite, in fact. That being said, I'm glad you guys are striving to and, apparently, succeeding in improving the quality of your code
As for the crux of the matter with regards to this thread, I have to take issue with your statement:
"I must also point out that the fact that one control has a certain feature (the screen boundary detection of the ComboBox for example) does not mean that all controls must have that feature. Often simplicity has more value than a new property that can be replaced with a bit of CSS or JS."
This statement makes absolutely no sense. All dropdown controls should have screen-boundary detection. If that isn't the case, why would you have implemented it in the first place with RadCombobox? Surely that didn't make things "simpler" for you. So, Telerik either doesn't have the technical competence to implement this feature in their other dropdown controls, or they lack the resources to do so. The former is obviously not true, since the feature does exist in other Telerik controls. But for some reason, even after 6 1/2 years, it still does not in RadtoolbarDropdown.
So, if the official Teleirk stance on this issue is... you should use Rad Menu in a toolbar template, then maybe you guys ought to deprecate the RadToolBarDropdown altogether. I mean, what other purpose does it serve? In addition to the screen boundary detection, its also missing a FindItemByValue method, which, again, seems like a glaring omission for a dropdowncontrol. Though I guess after 7 years, it looks like that feature will finally be implemented in the upcoming release...
Is that the typical turn-around time we should expect for the RadToolbar control?
Lastly, I'm not sure why you feel the need to list the various controls Telerik has released recently. Shear numbers impress no one, but perhaps somebody in marketing. If controls are released with bugs or have incomplete features, it may actually be worse than if they were not released at all. I'm not saying that is the case with the controls you mentioned. But if the pattern holds, it very well might be.
