WindowChrome.ResizeBorderThickness Property

.NET Framework (current version)

Gets or sets a value that indicates the width of the border that is used to resize a window.

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

public Thickness ResizeBorderThickness { get; set; }

Property Value

Type: System.Windows.Thickness

The width of the border that is used to resize a window.

Set the ResizeBorderThickness property to specify the width of the area where a user can click-and-drag to resize a window. The mouse pointer changes to resize arrows when it is moved over the resize border.

This property can be set to any non-negative double value. The values can be non-uniform. By default, the resize border will use system values to emulate the behavior of a standard window.

This area is only used to define the region that is used to resize the window; it does not have any visual elements associated with it. However, it does affect the layout of elements inside the resize border.
