design patterns - WPF, Xaml and Controls Factory? -

I want to create WPF controls in which there are some other controls: The main problem is how to select the right control based on the type of model is?

  & lt; MyControl & gt; & Lt ;! - If DataContext.GetType () == Type 1 - & gt; & Lt; Control1 DataContext = {binding} / & gt; & Lt ;! - If DataContext.GetType () == Type 2 - & gt; & Lt; Control2 DataContext = {binding} & gt; & Lt; / MyControl & gt;  

How can I apply it and design it well? My idea was to do something like this ...

  Control CreateControl (object datacontact) {if (dataContext.GetType () == TYpe1) return new Control1 () {DataContext = dataContext} (DataContext.GetType () == TYpe2) Return new Control2 () () {DataContext = dataContext}}  

but I do not know how I can add such a method XAM ...

You can define DataTemplates in resources, and ContentControl as a placeholder

Resource: < / P>

  & gt; DataTimeplate DataType = "{x: Type Model: Model1}" & gt; & Lt; Control 1 / & gt; & Lt; / DataTemplate & gt; & Lt; DataTemplate DataType = "{x: Type Model: Model2}" & gt; & Lt; Control2 / & gt; & Lt; / DataTemplate & gt;  

(Note that you do not need to explicitly set DataContext )

Usage:

  & lt; MyControl & gt; & Lt; Content control content = "{binding}" /> & Lt; / MyControl & gt; Based on the type of  content  
  
 

, select the appropriate DataTemplate .
