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

public double MinWidth { get; set; }

Property Value

Type: System.Double

A Double that represents the minimum width. The default value is 0.

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.
