I watched Davood video but I can't see RadWindow going over the TaskBar. There are shown other problems that I will try to explain:
1. The initial maximize bad maximize is caused because property SizeToContent
is set to true by default. If you set it to false it will be working as expected. This is also happening with Microsoft Window, if it is Maximized by code and SizeToContent
2. Bad Placement of Close button --This is an issue in the Example as the template is not refreshed properly, however if set this properties in an application before showing the RadWindow, it will work as expected. We will try to fix the example in one of our future releases.
Could you please explain how exactly you are showing the RadWindow over the taskbar. More info about your OS, version of controls or a screenshot would be of help.
All the best,
