XAML Values
uniformRadius
A value that specifies a uniform radius size in pixels. The uniformRadius value is applied to all four CornerRadius properties (TopLeft, TopRight, BottomRight, BottomLeft).topLeft
Sets the initial TopLeft.topRight
Sets the initial TopRight.bottomRight

If you specify an attribute string with two or three values, only the first value is respected and is treated as the uniformRadius (the other values are ignored). You must specify all four values to use a different behavior than uniformRadius.
In the XAML syntaxes shown, you can use a space rather than a comma as the delimiter between values.
