    <p>I'm trying to change the binding property of several columns from string to int since they are being read from a file and I want to use numeric sort when the data is finally displayed on screen.</p> <p>I created this converter and made the corresponding changes in the XAML file to implement the converter in the <code>DataTemplate</code> tag but I am still getting string sort in my output, not numeric sort. </p> <p>I looked around for other versions of a similar converter but didn't find anything relevant. I'm unsure of what the problem with my converter is. </p> <p>Here is my converter:</p> <pre><code>public class IntToStringConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value is string) { string s = (string)value; int num; if (int.TryParse(s, out num)) return num; } return 0; } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { int number = (int)value; return number.ToString(); } } </code></pre> <p>And these are the changes made in the <code>XAML</code>. The local <code>namespace</code> is defined in <code>Windows.Resources</code>.</p> <pre><code>&lt;me:IntToStringConverter x:Key="IntToStringConverter" /&gt; </code></pre> <p>The sorting part looks like this:</p> <pre><code>&lt;toolkit:DataGridTemplateColumn Width="55" Header="Min Run" SortMemberPath="MinRun"&gt; &lt;toolkit:DataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{ Binding Path=MinRun, Converter={StaticResource IntToStringConverter}}" HorizontalAlignment="Center" /&gt; &lt;/DataTemplate&gt; &lt;/toolkit:DataGridTemplateColumn.CellTemplate&gt; &lt;/toolkit:DataGridTemplateColumn&gt; </code></pre> <p><code>DataGrid</code> is bound here:</p> <pre><code>&lt;toolkit:DataGrid x:Name="myGrid" Grid.Row="1" Background="{x:Null}" Foreground="White" ItemsSource="{Binding ObsRacResults}" VirtualizingStackPanel.IsVirtualizing="True" BorderThickness="0" Margin="4" VerticalGridLinesBrush="#FF555555" AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeColumns="False" CanUserReorderColumns="False" HorizontalGridLinesBrush="#FF555555" SnapsToDevicePixels="True" CanUserResizeRows="False"&gt; </code></pre> <p>and then I have my columns, styles etc. </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.
