There are two additional suggestions to improve the reliability of this event, thank you aasgenirb235 and Colin for noting them in the comments: I am afraid this is a bug and there is not much we can do about it. While it usually fires several times for each accent color change, sometimes the event doesn’t fire at all. Warning:the event is not always reliable. Var isDarkMode = backgroundColor = Colors.Black We must query the UIColorType.Background color and check if it is black or white: var backgroundColor = sender.GetColorValue(UIColorType.Background) In the event handler we can check the accent color either by directly looking up the Resources dictionary or by the GetColorValue method: Color accentColor = sender.GetColorValue(UIColorType.Accent) Ĭolor accentColor = (Color)Resources Īccessing the light/dark mode setting is a little less intuitive. UiSettings.ColorValuesChanged += ColorValuesChanged UISettings uiSettings = new UISettings() Whereas the former event deals with text scaling, the latter event is fired whenever the system color settings are changed. In stark contrast to most other similar Windows Runtime APIs, the UISettings do not provide a Current singleton instance property nor a GetForCurrentView factory method, but just have a simple constructor.Īpart from many properties that let us query various UI related information ( CaretBlinkRate, CursorSize or even HandPreference ) it also has two useful events: TextScaleFactorChanged and ColorValuesChanged . In such cases the UISettings class comes in handy. Observing changesĪlthough using ThemeResource will be sufficient for most cases, sometimes we need to be notified about color changes outside of XAML. įor convenience there is also a accent color-based SolidColorBrush resource, under the not-so intuitive SystemControlHighlightAccentBrush key. To access the current accent color, we can use the SystemAccentColor key. Anytime the user changes the accent color or switches between dark and light mode, the resource is updated. This allows us to dynamically reference resources based on the currently selected system theme. XAML has a concept of ThemeResource markup extension. But what if the user changes settings at runtime? Thanks for helping make community forums a great place.Users love personalization and expect apps to adapt to their choices. For this purpose we can use the accent color.

Var backgroundproperty = Grid.BackgroundProperty īindingOperations.SetBinding(obj, backgroundproperty, new Binding Private static void GridBindingBackgroundPathPropert圜hanged(DependencyObject obj, DependencyPropert圜hangedEventArgs e) Public static readonly DependencyProperty BackgroundProperty =ĭependencyProperty.RegisterAttached("Background", typeof(string), typeof(BindingHelper), new PropertyMetadata(null, GridBindingBackgroundPathPropert圜hanged)) This enables animation, styling, binding, etc. Using a DependencyProperty as the backing store for Background. Public static void SetBackground(DependencyObject obj, string value) Return (string)obj.GetValue(BackgroundProperty) Public static string GetBackground(DependencyObject obj) You would have to use “x:key” in Style and set Style property in Grid. In addition, if you just use TargetType in the Style, the attached property won’t work. The attached property’s value is the property path in data source which in your case is OrderID.Īnd in your converter, you would need a Brush. In my code sample, I have defined a BindingHelper class to set binding, this class contained an attached property. So I have made a code sample using Grid for your reference, its principle is the same. Since I didn’t know you how to implement your custom DataGrid.
