softaware.Xaml.Converters

This Library contains various common implementations of the IValueConverter interface for WPF and UWP apps:

• BooleanConverter: Converts true/false to the values specified by the properties TrueValue and FalseValue. A BooleanToVisibilityConverter could be implemented like this:

<sxc:BooleanConverter x:Key="BooleanToVisibilityConverter" TrueValue="Visible" FalseValue="Collapsed"/>

• BooleanInverter: Converts true to false and vice versa.
• BooleanToVisibilityConverter: Converts true/false to Visible/Collapsed (or Hidden).
• EqualsConverter: Returns true when value and parameter are equal (according to the Equals method). In WPF the converter can also be used as IMultiValueConverter to compare two values bound via MultiBinding.
• NullConverter: Returns true when value is null, otherwise false. Empty strings can be treated as null by settings the TreatEmptyStringAsNull property to true.
• StringFormatConverter: Formats value using parameter as format string. The formatting of empty strings can be controlled with the FormatEmptyString property.
• EmptyConverter: Checks if value is an empty IEnumerable. The TreatNullAsEmpty property can be set to true or false.
• ContainsConverter: Checks if IEnumerable passed as value contains parameter. In WPF the converter can also be used as IMultiValueConverter to compare two bound values.
• MappingConverter: This converter enables the definition of the mapping directly in XAML (which is especially useful for enums):

<sxc:MappingConverter x:Key="StateConverter">
  <sxc:Mapping From="{x:Static common:State.Created}" To="Waiting..."/>
  <sxc:Mapping From="{x:Static common:State.InProgress}" To="In progress..."/>
  <sxc:Mapping From="{x:Static common:State.Finished}" To="Finished"/>
</sxc:MappingConverter>

• ConverterChain: This converter can be used to execute multiple converters in row. A BooleanToVisibilityConverter could be implemented like this:

<sxc:ConverterChain x:Key="NullToVisibilityConverter">
  <sxc:NullConverter/>
  <sxc:BooleanInverter/>
  <sxc:BooleanToVisibilityConverter/>
</vpc:ConverterChain>
