Parameters
propertyName
String String

The name of the BindableProperty.

returnType
Type Type

The type of the property.

declaringType
Type Type

The type of the declaring object.

defaultValue
Object Object

The default value for the property.

defaultBindingMode
BindingMode BindingMode

propertyChanged

A delegate to be run when the value has changed. This parameter is optional. Default is null.

propertyChanging

A delegate to be run when the value will change. This parameter is optional. Default is null.

coerceValue

A delegate used to coerce the range of a value. This parameter is optional. Default is null.

defaultValueCreator

A Func used to initialize default value for reference types.

Type Parameters
TDeclarer

The type of the declaring object.

TPropertyType

The type of the property.

Parameters
getter
Expression<Func<TDeclarer,TPropertyType>>

An expression identifying the getter for the property using this BindableProperty as backing store.

defaultValue

Default value for the BindableProperty.

defaultBindingMode
BindingMode BindingMode

The BindingMode to use on SetBinding() if no BindingMode is given. This parameter is optional. Default is BindingMode.OneWay.

validateValue
BindableProperty.ValidateValueDelegate<TPropertyType>

A delegate to be run when a value is set. This parameter is optional. Default is null.

propertyChanged
BindableProperty.BindingPropertyChangedDelegate<TPropertyType>

A delegate to be run when the value has changed. This parameter is optional. Default is null.

propertyChanging
BindableProperty.BindingPropertyChangingDelegate<TPropertyType>

A delegate to be run when the value will change. This parameter is optional. Default is null.

coerceValue
BindableProperty.CoerceValueDelegate<TPropertyType>

A delegate used to coerce the range of a value. This parameter is optional. Default is null.

defaultValueCreator
BindableProperty.CreateDefaultValueDelegate<TDeclarer,TPropertyType>

A Func used to initialize default value for reference types.

Returns

A newly created BindablePropertyKey.

Remarks

A BindablePropertyKey is used to restrict write access to a property, either via SetValue() or binding. A BindableProperty is usually defined too, to give broader read access
