If the autohiding feature of the taskbar is enabled and RadWindow is maximized, the taskbar is not displayed when the mouse is over the bottom of the screen.

This is observed also in RadTabbedWindow.

Hi,

our company is slowly rolling out high-DPI laptops to our users. On such devices, Windows automatically enables DPI scaling, using a value of 125% or 150%, depending on the screen's resolution. In combination with an external (unscaled) monitor, this causes our application, to appear blurry on the scaled screen.

Windows has built-in functionality to reduce the blurring, however, this only works on the main screen. If you connect a secondary screen and set that as your main screen, the application will always appear blurry on the laptop screen.

My understanding of the topic is that WPF is DPI aware - but on the system level. So it does not cope well with monitors that have different DPI settings. However, I found a tutorial on Microsoft Docs (https://docs.microsoft.com/en-gb/windows/win32/hidpi/declaring-managed-apps-dpi-aware?redirectedfrom=MSDN), hinting that it is possible to make WPF windows per-monitor DPI aware. Unfortunately, this workaround requires you to inherit your window class from their utility class.

Since all of our windows already inherit from RadWindow, I have no chance to include this without copying either their base class or RadWindow. Having RadWindow support per-monitor DPI awareness would be a great feature to have. Or is there already a way to support this?

PS: Why does the first feature form in the feature request workflow (the one, where it first searches for similar requests) not let me select the control/area I am searching for like the one for private tickets? I almost submitted this request for the Area "All (Multiple Controls)" because of that.

If you open the window on a specific resolution, maximize it and then change the resolution to a bigger one, the window size is not updated. The window stays in the original resolution of the screen.

To work this around subscribe to the SystemEvents.DisplaySettingsChanged event and reset the WindowState of RadWindow.

public MainWindow() // where MainWindow is RadWindow
{
	InitializeComponent();
	SystemEvents.DisplaySettingsChanged += SystemEvents_DisplaySettingsChanged;
}

private void SystemEvents_DisplaySettingsChanged(object sender, EventArgs e)
{
	if (this.WindowState == WindowState.Maximized)
	{
		this.WindowState = WindowState.Normal;
		this.WindowState = WindowState.Maximized;
	}
}

Hi,

Please see attached project,

After use animation changed window size and use the mouse to drag to change the size of the window,

When the window size is smaller than the original size, the upper right button will be hide,

Original WPF Window no this problem, And changing size animation very Smooth then RadWIndow.

PreviewClosed event is called twice when using custom close button in DialogWindow

There should be an easy method to add/override the shadow of a RadWindow. Either via XAML attributes or code behind.

As an example Windows 10 OS Window gets different Opacity for its Title and Buttons when Inactive (open two Window-s and make them appear one behind the other -- the one in the background of the active window is inactive). Our Office2016 and Office2016 Touch themes are inspired by Windows 10 OS as we officially stated so we might mind adding this visual appearance on our side for RadWindow.

The property is present, but it is not implemented.
