Member Data Documentation

readonly DependencyProperty WPFCustomControls::ContextQueries::MultiContextQuery::RootProperty [static]

Initial value:

        DependencyProperty.Register(
            "Root",
            typeof(bool),
            typeof(MultiContextQuery),
            new PropertyMetadata(false, OnRootPropertyChanged))

Indicates that this MultiContextQuery is the root of its query tree.

Root affects how the Label is formatted. This property must be set externally, the MultiContextQuery does not determine if it has a parent automatically.

readonly DependencyProperty WPFCustomControls::ContextQueries::MultiContextQuery::ConverterProperty [static]

Initial value:

        DependencyProperty.Register(
            "Converter",
            typeof(IMultiValueConverter),
            typeof(MultiContextQuery),
            new PropertyMetadata(new AndMultiValueConverter()))

Converter used to combine the child query results into this query's result.

Defaults to AndMultiValueConverter.

readonly DependencyProperty WPFCustomControls::ContextQueries::MultiContextQuery::FallbackValueProperty [static]

Initial value:

 
        DependencyProperty.Register(
            "FallbackValue",
            typeof(bool),
            typeof(MultiContextQuery),
            new PropertyMetadata(true, new PropertyChangedCallback(OnFallbackValuePropertyChanged)) )

Value applied when there are no ContextQueries in the Queries list.

Indicates that this MultiContextQuery is the root of its query tree.

Root affects how the Label is formatted. This property must be set externally, the MultiContextQuery does not determine if it has a parent automatically.

IMultiValueConverter WPFCustomControls::ContextQueries::MultiContextQuery::Converter [get, set]

Converter used to combine the child query results into this query's result.

Defaults to AndMultiValueConverter.
