MeasureConverter Class

The MeasureConverter class provides a way to convert a measure in twips (twentieth of a point) to a value in another measuring unit. Twips are the measuring unit used by TXTextControl. Possible conversions are handled through the Unit property. The result of the conversion is a string or a double, which can be used to display the value for the user. This class can be used in XAML as a static resource to automatically convert bound property values.

Syntax

• C#
• VB.NET

​[ValueConversion(typeof(int), typeof(string))]
[ValueConversion(typeof(int), typeof(double))]
public class MeasureConverter : IValueConverter

​Public Class MeasureConverter
  Implements IValueConverter

Examples

The following XAML example binds the InputFormat.TopDistance property to a text box using the WPF.MeasureConverter class. The value of the top distance is converted to centimeter.
