IsLessThanValueConverter

class.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WPF.Controls.Office

Reports whether a bound size is under 40 device-independent units.

public class IsLessThanValueConverter : IValueConverter

Inherits from / implements: IValueConverter

Remarks

The ribbon's scroll bars use it to drop the grip lines from a thumb too short to hold them. The threshold is fixed. The converter is public so that a template of your own can use the same test.
