#### Property Value

The x-axis radius of the ellipse that is used to round the corners of the rectangle.

This property is read/write. The default value is 0.

#### Remarks

For the rectangle to have rounded corners, both the **RadiusX** and RadiusY properties must be non-zero.

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. Values greater than half the rectangle's width are treated as though equal to half the rectangle's width. Negative values are treated as positive values.
