CornerRadius Structure
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Describes the characteristics of a rounded corner, such as can be applied to a Border.
Namespace: System.Windows
Assembly: System.Windows (in System.Windows.dll)
Syntax
'Declaration
Public Structure CornerRadius
public struct CornerRadius
<CornerRadius ...>topLeft,topRight,bottomRight,bottomLeft</CornerRadius>
<object property="uniformRadius"/>
- or -
<object property="topLeft,topRight,bottomRight,bottomLeft"/>
XAML Values
uniformRadius
A value that specifies a uniform radius. The uniformRadius value is applied to all four CornerRadius properties (BottomLeft, TopLeft, TopRight, BottomRight).topLeft
Sets the initial TopLeft.topRight
Sets the initial TopRight.bottomRight
Sets the initial BottomRight.bottomLeft
Sets the initial BottomLeft.
If you specify an attribute string or initialization text 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.
You can use a space rather than a comma as the delimiter between values.
The CornerRadius type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|

CornerRadius(Double) | Initializes a new CornerRadius structure, applying the same uniform radius to all its corners. |
|
CornerRadius(Double, Double, Double, Double) | Initializes a new instance of the CornerRadius structure, applying specific radius values to its corners. |

BottomLeft | Gets or sets the radius of rounding, in pixels, of the bottom left corner of the object where a CornerRadius is applied. |
|
BottomRight | Gets or sets the radius of rounding, in pixels, of the bottom right corner of the object where a CornerRadius is applied. |
|
TopLeft | Gets or sets the radius of rounding, in pixels, of the top left corner of the object where a CornerRadius is applied. |
|
TopRight | Gets or sets the radius of rounding, in pixels, of the top right corner of the object where a CornerRadius is applied. |

Remarks
Properties of CornerRadius do not support an attribute syntax in XAML for Silverlight. In XAML you should always specify CornerRadius-type properties through one of the following usages:
The XAML attribute usage, which infers properties that use the CornerRadius type and uses a type converter to process the attribute string into the specific values for the CornerRadius.
A property element usage, containing a CornerRadius object element. For that object element, set the CornerRadius properties using initialization text, as shown in the XAML Object Element Usage.
If you specify a CornerRadius for use as a resource, use the object element usage and set the CornerRadius properties using initialization text.
