Namespace:  System.Windows
Assembly:  System.Windows (in System.Windows.dll)


Public Property MaxWidth As Double
public double MaxWidth { get; set; }
<frameworkElement MaxWidth="double"/>

Property Value

Type: System.Double
The maximum width of the object, in pixels. The default is PositiveInfinity. This value can be any value equal to or greater than 0. PositiveInfinity is also valid.


Dependency property identifier field: MaxWidthProperty

This is one of three properties on FrameworkElement that specify width information. The other two are MinWidth and Width. If there is a conflict between these values, the order of application for actual width determination is first MinWidth must be honored, then MaxWidth, and finally if each of these are within bounds, Width.

Non-integral values for MaxWidth are technically permitted, but should generally be avoided and are normally rounded by the default layout rounding behavior. See Layout Rounding.
