XAML Values

double

Double

String representation of a Double value equal to or greater than 0.0. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For instance a value of 1 is acceptable.

The same Double range restrictions as mentioned in the Property Value section apply, except that you must use x:Static Markup Extension to set the value to be PositiveInfinity.

qualifiedDouble

A double value as described above, followed by one of the following unit declaration strings: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px

Property Value

Type: System.Double
The maximum width of the element, in device-independent units (1/96th inch per unit). The default value is PositiveInfinity. This value can be any value equal to or greater than 0.0. PositiveInfinity is also valid.

Identifier field

MaxWidthProperty

Metadata properties set to true

AffectsMeasure

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.

The value restrictions on the Double value are enforced by a ValidateValueCallback mechanism. If you attempt to set an invalid value, a run-time exception is thrown.
