XAML Values

double

Double

String representation of a Double value equal to or greater than 0.0034 but equal to or less than 160000. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.

qualifiedDouble

A double value as described above, (excepting Auto) followed by one of the following unit specifiers: 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
A Double that represents the minimum width. The default value is 0.

Identifier field

WidthProperty

Metadata properties set to true

None

When you use these values together in the same code example, the MinWidth value takes precedence over the MaxWidth value, which in turn takes precedence over the Width value.

When you add or remove rows or columns , the ActualWidth for all ColumnDefinition elements and the ActualHeight of all RowDefinition elements becomes zero until Measure is called.
