You can use the following code for loading GIFImage in a WPF app <pre><code> using System; using System.Windows; using System.Windows.Controls; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Media.Imaging; /// <summary> /// Class to host nornmal and Gif images and plays the animation. /// To make it work, instead of setting ImageSource, set the AnimationSourcePath property. /// </summary> public class GifImage : Image { /// <summary> /// Dependency property to hold value for AnimationSourcePath. /// </summary> public static readonly DependencyProperty AnimationSourcePathProperty = DependencyProperty.Register( "AnimationSourcePath", typeof(string), typeof(GifImage), new UIPropertyMetadata(String.Empty, AnimationSourcePathPropertyChanged)); /// <summary> /// Dependency property to hold value of integer animation timeline values for FrameIndex. /// </summary> private static readonly DependencyProperty FrameIndexProperty = DependencyProperty.Register( "FrameIndex", typeof(int), typeof(GifImage), new UIPropertyMetadata(0, new PropertyChangedCallback(ChangingFrameIndex))); /// <summary> /// Dependency property to hold value of integer animation rate which slows down animation speed if value is more than 1. /// </summary> private static readonly DependencyProperty FrameRefreshRateProperty = DependencyProperty.Register( "FrameRefreshRate", typeof(int), typeof(GifImage), new UIPropertyMetadata(1, AnimationSourcePathPropertyChanged)); /// <summary> /// Member to hold animation timeline for integer values. /// </summary> private Int32Animation anim; /// <summary> /// Member to hold flag to indicate if animation is working. /// </summary> private bool animationIsWorking = false; /// <summary> /// Member to hold Gif Bitmap Decoder. /// </summary> private GifBitmapDecoder gf; /// <summary> /// Initializes a new instance of the GifImage class. /// </summary> public GifImage() { } /// <summary> /// Initializes a new instance of the GifImage class based on the uri. /// </summary> /// <param name="uri">Uri of the image source.</param> public GifImage(Uri uri) { GifImage.SetupAnimationSource(this, uri); } /// <summary> /// Gets or sets a value indicating AnimationSourcePath. /// </summary> public string AnimationSourcePath { get { return (string)GetValue(AnimationSourcePathProperty); } set { SetValue(AnimationSourcePathProperty, value); } } /// <summary> /// Gets or sets a value indicating FrameIndex. /// </summary> public int FrameIndex { get { return (int)GetValue(FrameIndexProperty); } set { SetValue(FrameIndexProperty, value); } } /// <summary> /// Gets or sets a value for frame refresh rate.

Guidance

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.
