Gets or sets the maximum number of frames to render per second.
Assembly: System.Windows (in System.Windows.dll)
The actual frame rate that Silverlight content renders depends on system load performance. You can specify the range using the property:
The minimum frame rate is 1.
The maximum frame rate is platform-dependent. A value of approximately 60 frames-per-second should be reliable on all platforms. The 1000 and 30000 frames-per-second range is where the maximum frame rate could differ between platforms.
Note that there is a mismatch in naming between the parameter in createObject/createObjectEx and the runtime property. The instantiation parameter is named framerate, this runtime property is named , but these are both referring to the same value.
You can display a frame rate counter for diagnostic purposes. Fore more information, see EnableFrameRateCounter.
The following code example demonstrates how to use this property.
// The Host object, which represents the host Silverlight plug-in. System.Windows.Interop.SilverlightHost host = Application.Current.Host; // The following code demonstrates how to use the Host object // to access other APIs in the System.Windows.Interop namespace. // The IsVersionSupported method. This method is useful when // you want to implement an upgrade experience in managed code. bool isSupported = host.IsVersionSupported("2.0.30908.0"); // Read-only properties of the Host object. System.Windows.Media.Color pluginBackground = host.Background; bool loaded = host.IsLoaded; Uri source = host.Source; // The Settings object, which represents Web browser settings. System.Windows.Interop.Settings settings = host.Settings; // Read/write properties of the Settings object. settings.EnableFrameRateCounter = true; settings.EnableRedrawRegions = true; settings.MaxFrameRate = 60; // Read-only properties of the Settings object. bool windowless = settings.Windowless; bool htmlAccessEnabled = settings.EnableHTMLAccess; // The Content object, which represents the plug-in display area. System.Windows.Interop.Content content = host.Content; // The read/write IsFullScreen property of the Content object. // See also the Content.FullScreenChanged event. bool isFullScreen = content.IsFullScreen; // Read-only properties of the Content object. These properties do // not contain meaningful values until after the Content.Resized // event occurs for the first time. double actualWidth = content.ActualWidth; double actualHeight = content.ActualHeight;
