XAML Values

If you use an existing command library command, see that command library's documentation for XAML usage information, including which type of CommandParameter the command expects. If you use a custom command, see Remarks.

Most existing commands from the command libraries do not use a command parameter. Of the commands that do use a command parameter, most of these take a parameter with some primitive type value, such as an integer or a string. However, it is possible to create a custom command where that command expects a nonprimitive type as its command parameter. For a custom command case like this, setting CommandParameter in code might require a new or existing object instance. Setting CommandParameter in markup might require property element syntax, where the object element filling the property element syntax is a new element of the type expected by that command. Alternatively, setting in markup might require a reference through a markup extension to an existing object (typically these references are made with Binding Markup Extension or StaticResource Markup Extension).
