Silverlight 1.0 doesn't have any of the standard UI controls you may be used to. Instead you have a collection of visual elements that can be combined to create your own controls, or you may simply want to use existing HTML controls outside your Silverlight application for input. This major limitation has been removed in Silverlight 2.0.
The basic controls in Silverlight 1.0 are:
| Name | Description |
|---|---|
| Canvas | The Canvas object is the only layout control available in Silverlight 1.0 and it must be the root element for all XAML documents. Child objects get
the Left and Top attached properties for placement within the Canvas. As Silverlight 1.0 is not resolution independent like WPF, all
coordinates are pixel based and not affected by the monitor resolution. |
| Image | Displays bitmap images with support for applying both geometry and opacity based masks. Supported file formats are JPG and PNG (indexed color: 1, 4, or 8 bit. Truecolor: 24 bit and 32 bit with alpha). |
| InkPresenter | Displays ink strokes from a collection of Strokes. |
| TextBlock | Displays text and glyphs. In addition to the standard nine web fonts (Arial, Arial Black, Comic Sans MS, Courier New, Georgia, Lucida Grande/Lucida Sans Unicode, Times New Roman, Trebuchet MS, and Verdana), you may optionally load custom TrueType or OpenType fonts. |
Shapes let you draw vector based graphics in your application and they can also be used as masks for other elements.
| Name | Description |
|---|---|
| Line | Displays a line from point A to point B. |
| Ellipse | Displays an ellipse or circle. |
| Path | Displays lines or curves between a given set of points. |
| Polygon | Displays a closed shape from a connected set of points. |
| Polyline | Displays a set of connected straight lines. |
| Rectangle | Displays a rectangle with an optional stroke (border) and fill. |
Brushes are used to paint the surfaces such as fills, backgrounds and the outlines of controls.
| Name | Description |
|---|---|
| SolidColorBrush | Paints the surface using a single color. The color to use can be specified using the well known name or its hexadecimal notation #rrggbb. In addition,
you may specify the opacity (alpha) using #aarrggbb. |
| LinearGradientBrush | Paints the surface using a gradient. You may specify multiple colors with GradientStops and modify the angle and direction. |
| RadialGradientBrush | Paints the surface similar to the LinearGradientBrush, but instead of following a straight line, the gradient axis is defined by a circle. |
| ImageBrush | Paints the surface using a bitmap image. You may specify the stretch behavior of the image to handle drawing on surfaces that aren't the same size as the source image. |
| VideoBrush | Paints the surface similar to the ImageBrush, but instead of using a static image as the source, it uses a video played by a MediaElement. |
Silverlight supports the following media file formats, along with Advanced Stream Redirector (ASX) playlist files:
Video:
Audio:
| Name | Description |
|---|---|
| MediaElement | Plays audio and video files. This element does not need to be visible on the screen if used for audio playback or as a source for a VideoBrush. |
