How to specify generic type argument in XAML

I have a BaseView for my MVP - PRISM WPF application. Now for some reason we thought to make the _presenter as a Templated field in the BaseView.

earlier i had the view xaml representation as

<base:BaseView xamlns:base="clr address of the dll which had BaseView" >

</base:BaseView>

now since i 开发者_C百科have changed the BaseView to BaseView<TPresenter>, So how shall i write the Xaml then?

You can do it since .NET 4 Framework and XAML 2009. See Generics in XAML on MSDN

For instance:

<my:BusinessObject x:TypeArguments="x:String,x:Int32"/>

For .NET 3.5:

For XAML 2006 usage when specifically targeting WPF, x:Class must also be provided on the same element as x:TypeArguments, and that element must be the root element in a XAML document. The root element must map to a generic type with at least one type argument. An example is PageFunction.

Possible workarounds to support generic usages include defining a custom markup extension that can return generic types, or providing a wrapping class definition that derives from a generic type but flattens the generic constraint in its own class definition.

In case this happens to someone. I had a similar scenario where I converted my base class to a templated class (i.e. BaseView to BaseView). I kept receiving errors in the InitializeComponent() method. I was receiving the null exception error in the x:Class base type's InitializeComponent() call. I was able to resolve the errors by removing the form-level events from the XAML definition. If I had to keep the form-level events I would need to move them to BaseView.
