    <p>Check out the previous question <a href="https://stackoverflow.com/questions/8713864/high-performance-graphics-using-the-wpf-visual-layer/8714107#8714107">High Performance Graphics using the WPF Visual Layer</a> for a good related discussion. While WPF provides a great framework for rich vector graphics, it lacks somewhat for real-time 2D performance. </p> <p>There are workarounds, for instance, depending on your scene complexity you may get away with using <a href="http://msdn.microsoft.com/en-us/library/system.windows.media.drawingvisual.aspx" rel="nofollow noreferrer">DrawingVisuals</a> or virtualized Shape classes (WPF Vector graphics) to draw your sprites. Going a little lower level, you could cache sprites using the <a href="http://msdn.microsoft.com/en-us/library/system.windows.media.bitmapcache%28v=vs.95%29.aspx" rel="nofollow noreferrer">BitmapCache</a> mode available in .NET4.0, or pre-prendering them to Bitmaps and using various <a href="https://stackoverflow.com/questions/9317460/bitmap-performance-optimization-patterns/9467543#9467543">optimization patterns</a> to improve throughput. </p> <p>Going lower level still, you can mix Vector/Raster graphics using the fantantastic <a href="http://writeablebitmapex.codeplex.com/" rel="nofollow noreferrer">WriteableBitmapEx</a> project, or Vector/GPU graphics using the <a href="http://www.codeproject.com/Articles/28526/Introduction-to-D3DImage" rel="nofollow noreferrer">D3DImage</a>. </p> <p>Regarding how to update your scene, you'll need to write a primitive game engine where on the <a href="http://msdn.microsoft.com/en-us/library/system.windows.media.compositiontarget.rendering.aspx" rel="nofollow noreferrer">CompositionTarget.Rendering</a> event (fired on redraw of the screen) you get the updated parameters and compute positions/orientations of your sprites. Something that might help with this is this great <a href="http://physicshelper.codeplex.com/" rel="nofollow noreferrer">codeplex project</a> which integrates WPF/Silverlight and Farseer physics. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
