    <p>There's an <a href="http://www.codeproject.com/Articles/32629/A-better-panel-for-data-binding-to-a-WrapPanel-in" rel="nofollow">UniformWrapPanel</a> article on codeproject.com, which I modified to ensure the items in a wrap panel have uniform width and fit to the width of the window. You should easily be able to modify this code to have a maximum number of columns. Try changing the code near</p> <pre><code>var itemsPerRow = (int) (totalWidth/ItemWidth); </code></pre> <p>in order to specify the max columns.</p> <p>Here's the code:</p> <pre><code>public enum ItemSize { None, Uniform, UniformStretchToFit } public class UniformWrapPanel : WrapPanel { public static readonly DependencyProperty ItemSizeProperty = DependencyProperty.Register( "ItemSize", typeof (ItemSize), typeof (UniformWrapPanel), new FrameworkPropertyMetadata( default(ItemSize), FrameworkPropertyMetadataOptions.AffectsMeasure, ItemSizeChanged)); private static void ItemSizeChanged( DependencyObject sender, DependencyPropertyChangedEventArgs e) { var uniformWrapPanel = sender as UniformWrapPanel; if (uniformWrapPanel != null) { if (uniformWrapPanel.Orientation == Orientation.Horizontal) { uniformWrapPanel.ItemWidth = double.NaN; } else { uniformWrapPanel.ItemHeight = double.NaN; } } } public ItemSize ItemSize { get { return (ItemSize) GetValue(ItemSizeProperty); } set { SetValue(ItemSizeProperty, value); } } protected override Size MeasureOverride(Size availableSize) { var mode = ItemSize; if (Children.Count &gt; 0 &amp;&amp; mode != ItemSize.None) { bool stretchToFit = mode == ItemSize.UniformStretchToFit; if (Orientation == Orientation.Horizontal) { double totalWidth = availableSize.Width; ItemWidth = 0.0; foreach (UIElement el in Children) { el.Measure(availableSize); Size next = el.DesiredSize; if (!(Double.IsInfinity(next.Width) || Double.IsNaN(next.Width))) { ItemWidth = Math.Max(next.Width, ItemWidth); } } if (stretchToFit) { if (!double.IsNaN(ItemWidth) &amp;&amp; !double.IsInfinity(ItemWidth) &amp;&amp; ItemWidth &gt; 0) { var itemsPerRow = (int) (totalWidth/ItemWidth); if (itemsPerRow &gt; 0) { ItemWidth = totalWidth/itemsPerRow; } } } } else { double totalHeight = availableSize.Height; ItemHeight = 0.0; foreach (UIElement el in Children) { el.Measure(availableSize); Size next = el.DesiredSize; if (!(Double.IsInfinity(next.Height) || Double.IsNaN(next.Height))) { ItemHeight = Math.Max(next.Height, ItemHeight); } } if (stretchToFit) { if (!double.IsNaN(ItemHeight) &amp;&amp; !double.IsInfinity(ItemHeight) &amp;&amp; ItemHeight &gt; 0) { var itemsPerColumn = (int) (totalHeight/ItemHeight); if (itemsPerColumn &gt; 0) { ItemHeight = totalHeight/itemsPerColumn; } } } } } return base.MeasureOverride(availableSize); } } </code></pre>

    1. COSweet! Thanks Phil. I managed to tailor this according to my requirement. Btw are there any performance issues in using a WrapPanel?

    2. COI couldn't say about performance. Seems to work ok with around 30-40 items. You'll need to try it.

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.
