CornerRadius Structure
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Describes the characteristics of a rounded corner, such as can be applied to a Border.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
<CornerRadius ...>topLeft,topRight,bottomRight,bottomLeft</CornerRadius>
<object property="uniformRadius"/> - or - <object property="topLeft,topRight,bottomRight,bottomLeft"/>
XAML Values
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.
| 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. |
| Name | Description | |
|---|---|---|
![]() | BottomLeft | Gets or sets the radius of rounding, in logical pixels, of the bottom left corner of the object where a CornerRadius is applied. |
![]() | BottomRight | Gets or sets the radius of rounding, in logical pixels, of the bottom right corner of the object where a CornerRadius is applied. |
![]() | TopLeft | Gets or sets the radius of rounding, in logical pixels, of the top left corner of the object where a CornerRadius is applied. |
![]() | TopRight | Gets or sets the radius of rounding, in logical pixels, of the top right corner of the object where a CornerRadius is applied. |
| Name | Description | |
|---|---|---|
![]() | Equals(CornerRadius) | Compares this CornerRadius structure to another CornerRadius structure for equality. |
![]() | Equals(Object) | Compares this CornerRadius structure to another object for equality. (Overrides ValueType::Equals(Object).) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Returns the hash code of the structure. (Overrides ValueType::GetHashCode().) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns the string representation of the CornerRadius structure. (Overrides ValueType::ToString().) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equality | Compares the value of two CornerRadius structures for equality. |
![]() ![]() | Inequality | Compares two CornerRadius structures for inequality. |
Properties of CornerRadius do not support an attribute syntax in XAML for Windows Phone. 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.
