Gets or sets the x-radius of the ellipse that is used to round the corners of the rectangle.
Assembly: System.Windows (in System.Windows.dll)
Dependency property identifier field: RadiusXProperty
For the rectangle to have rounded corners, both the and RadiusY properties must be nonzero.
A value greater than or equal to zero and less than or equal to half the rectangle's width that describes the x-radius of the ellipse is used to round the corners of the rectangle. A value greater than half the rectangle's width is treated as though equal to half the rectangle's width. A negative value is treated as a positive value.
The following illustration shows three rectangles with varying degrees of rounded corners.
