Gets or sets the border thickness of a control.
Assembly: System.Windows (in System.Windows.dll)
<control BorderThickness="uniform"/> - or - <control BorderThickness="left&right,top&bottom"/> - or - <control BorderThickness="left,top,right,bottom"/>
In the XAML syntaxes shown above, you can also use a space rather than a comma as the delimiter between values.
See Remarks for additional notes about value constraints.
Property ValueType: System.Windows.Thickness
A thickness value; the default is a thickness of 0 on all four sides.
Dependency property identifier field: BorderThicknessProperty
This property only affects a control whose template uses the property as a parameter. On other controls, this property has no impact.
Non-integral values of a Thickness for are technically permitted, but should generally be avoided. Non-integral values will introduce subpixel rendering, which can possibly result in antialiasing artifacts.
