with below code-behind:
public partial class AuditsList : UserControl
{
public List<Anomaly> anomalies { get; set; }
public Lookup<string, Anomaly> groupedAnomalies { get; set; }
public List<KeyValuePair<string, List<Anomaly>>> groupedAnomalies2 { get; set; }

return aaa;

}
I have also defined below classes:
namespace auditsListTest
{
public class Slide
{
public int SlideIndex { get; set; }
public string Name { get; set; }
}
}
public class Audit
{
public string Name { get; set; }
public string Description { get; set; }
public int Priority { get; set; }
public virtual List<Anomaly> PerformAudit(double progress)
{
return new List<Anomaly>();
}
}
public class Anomaly
{
public string Name { get; set; }
public Audit Audit { get; set; }
public string Description { get; set; }
public bool Fixed { get; set; }
public bool Allowed { get; set; }
public string Container { get; set; }
public Slide Slide { get; set; }
public void Fix()
{
Fixed = true;
}
public void Allow()
{
Allowed = true;
}
}
public class AnomalyComplex : Anomaly
{
public List<KeyValuePair<string, List<string>>> GroupDescriptions { get; set; }
}
public class AnomalyStandard : Anomaly
{
public string DescriptionDetailed { get; set; }
}
What is the problem? First, textblocks with binding defined in Expander.HeaderTemplate are not showing values.
<TextBlock DockPanel.Dock="Left"
Text="{Binding Key}" />
<TextBlock DockPanel.Dock="Right"
HorizontalAlignment="Right">
<Run Text="Issues " />
<Run Text="{Binding Value.Count}" />
Second problem is with datatemplates with datatypes (DataType="local2:AnomalyComplex" and DataType="local2:AnomalyStandard") that are not automatically used. Should I use DataTemplateSelectors?
<ContentControl>
<ItemsControl ItemsSource="{Binding Value}" />
</ContentControl>
Could you analyze code and let me know where is problem, and how to solve it? Thanks in advance.
First, textblocks with binding defined in Expander.HeaderTemplate are not showing values.
Bind the Header property to the KeyValuePair<string, List<Anomaly>>:
<Expander Name="expander" Header="{Binding}">
<Expander.HeaderTemplate>
<DataTemplate>
<DockPanel LastChildFill="True" HorizontalAlignment="Stretch">
<TextBlock DockPanel.Dock="Left" Text="{Binding Key}" />
<TextBlock DockPanel.Dock="Right" HorizontalAlignment="Right">
<Run Text="Issues " />
<Run Text="{Binding Value.Count, Mode=OneTime}" />
</TextBlock>
</DockPanel>
</DataTemplate>
</Expander.HeaderTemplate>
...
</Expander>
