XAML Values

  • 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.

Property Value

Type: System.Windows.CornerRadius
The degree to which the corners are rounded.

Remarks

CornerRadius can be a single uniform value for all corners or four unique values. For more information, see CornerRadius.

<Border Background="Cyan" CornerRadius="20" Grid.Column="2" Grid.Row="2">
