    <p>Here is my solution to the problem:</p> <pre><code>public static BindingBase CloneBinding(BindingBase bindingBase, object source) { var binding = bindingBase as Binding; if (binding != null) { var result = new Binding { Source = source, AsyncState = binding.AsyncState, BindingGroupName = binding.BindingGroupName, BindsDirectlyToSource = binding.BindsDirectlyToSource, Converter = binding.Converter, ConverterCulture = binding.ConverterCulture, ConverterParameter = binding.ConverterParameter, //ElementName = binding.ElementName, FallbackValue = binding.FallbackValue, IsAsync = binding.IsAsync, Mode = binding.Mode, NotifyOnSourceUpdated = binding.NotifyOnSourceUpdated, NotifyOnTargetUpdated = binding.NotifyOnTargetUpdated, NotifyOnValidationError = binding.NotifyOnValidationError, Path = binding.Path, //RelativeSource = binding.RelativeSource, StringFormat = binding.StringFormat, TargetNullValue = binding.TargetNullValue, UpdateSourceExceptionFilter = binding.UpdateSourceExceptionFilter, UpdateSourceTrigger = binding.UpdateSourceTrigger, ValidatesOnDataErrors = binding.ValidatesOnDataErrors, ValidatesOnExceptions = binding.ValidatesOnExceptions, XPath = binding.XPath, }; foreach (var validationRule in binding.ValidationRules) { result.ValidationRules.Add(validationRule); } return result; } var multiBinding = bindingBase as MultiBinding; if (multiBinding != null) { var result = new MultiBinding { BindingGroupName = multiBinding.BindingGroupName, Converter = multiBinding.Converter, ConverterCulture = multiBinding.ConverterCulture, ConverterParameter = multiBinding.ConverterParameter, FallbackValue = multiBinding.FallbackValue, Mode = multiBinding.Mode, NotifyOnSourceUpdated = multiBinding.NotifyOnSourceUpdated, NotifyOnTargetUpdated = multiBinding.NotifyOnTargetUpdated, NotifyOnValidationError = multiBinding.NotifyOnValidationError, StringFormat = multiBinding.StringFormat, TargetNullValue = multiBinding.TargetNullValue, UpdateSourceExceptionFilter = multiBinding.UpdateSourceExceptionFilter, UpdateSourceTrigger = multiBinding.UpdateSourceTrigger, ValidatesOnDataErrors = multiBinding.ValidatesOnDataErrors, ValidatesOnExceptions = multiBinding.ValidatesOnDataErrors, }; foreach (var validationRule in multiBinding.ValidationRules) { result.ValidationRules.Add(validationRule); } foreach (var childBinding in multiBinding.Bindings) { result.Bindings.Add(CloneBinding(childBinding, source)); } return result; } var priorityBinding = bindingBase as PriorityBinding; if (priorityBinding != null) { var result = new PriorityBinding { BindingGroupName = priorityBinding.BindingGroupName, FallbackValue = priorityBinding.FallbackValue, StringFormat = priorityBinding.StringFormat, TargetNullValue = priorityBinding.TargetNullValue, }; foreach (var childBinding in priorityBinding.Bindings) { result.Bindings.Add(CloneBinding(childBinding, source)); } return result; } throw new NotSupportedException("Failed to clone binding"); } </code></pre>

    1. COWhy are ElementName and RelativeSource commented out? I'm guessing you encountered an issue when trying to clone those properties?

    2. COBinding only allows you to set one of ElementName, RelativeSource or Source. If you try to set more than one, it throws an InvalidOperationException.

    3. COI was having trouble using the above, except I was copying the source from the old binding to the new. In my case the binding inherits the DataContext as its source. When I copy source, it explicitly sets null as the source which apparently causes the DataContext not to be used. To overcome this, use: 'Source = binding.Source ?? DependencyProperty.UnsetValue;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
