How to: Use System Parameters Keys
System resources expose a number of system metrics as resources to help developers create visuals that are consistent with system settings. xref:System.Windows.SystemParameters is a class that contains both system parameter values and resource keys that bind to the values—for example, xref:System.Windows.SystemParameters.FullPrimaryScreenHeight%2A and xref:System.Windows.SystemParameters.FullPrimaryScreenHeightKey%2A. System parameter metrics can be used as either static or dynamic resources. Use a dynamic resource if you want the parameter metric to update automatically while the application runs; otherwise use a static resource.
Note
Dynamic resources have the keyword Key appended to the property name.
The following example shows how to access and use system parameter dynamic resources to style or customize a button. This XAML example sizes a button by assigning xref:System.Windows.SystemParameters values to the button's width and height.
