ColumnDefinition.MaxWidth Property


Gets or sets a value that represents the maximum width of a ColumnDefinition.

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

public double MaxWidth { get; set; }

Property Value

Type: System.Double

A Double that represents the maximum width. The default value is PositiveInfinity.

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.

A double value as described above, (excepting Auto) followed by one of the following unit specifiers: px, in, cm, pt.

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

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