XAML Values

  • parameter
    A parameter value that is either a primitive value, or can be type converted from a string.

  • parameterReference
    A parameter value that is obtained as a reference to an already existing object. Typically the object is created in a ResourceDictionary and given a key, then referenced by using the StaticResource markup extension.

Property Value

Type: System.Object
A parameter to be passed to the Converter. This can be used in the conversion logic. The default is nulla null reference (Nothing in Visual Basic).

Exceptions

Exception Condition
InvalidOperationException

The Binding has already been attached to a target element, and cannot be modified.

Remarks

XAML Usage Notes

ConverterParameter can be set as a binding property through the Binding markup extension, which enables specifying an entire Binding as an attribute string. For more information, see Binding Markup Extension.

Property element syntax to create an object element that fills a Binding.ConverterParameter property element is possible, but uncommon.
