ContentTemplate selection based upon the DataContext in Silverlight 4

Question

In my Master/detail scenario, I have a datagrid as master and a UserControl as child. When a particular Row being selected in master grid I assign it to the UserControl's DataContext. In my User Control I have couple of DataTemplates as Resources and ContentControl as the Child Container. What I'm struggling with is how to dynamically select the ContentTemplate of ContentControl based upon the UserControl's DataContext's property TemplateName.

<ContentControl ContentTemplate="{Binding Source={StaticResource ????}}" Content="{Binding}"/>

Answer 1

You need to use DataTemplateSelector class. Read more here

UPDATE

In your case you should also check ContentTemplateSelector MSDN Article

You have to inherit from DataTemplateSelector, override and implement method SelectTemplate.

Then in XAML declare it as resource with specified key like this:

<DataTemplateSelectors:YourTemplateSelector x:Key="yourTemplateSelector"/>

Then in your ContentControl use it like this:

<ContentControl ContentTemplateSelector="{StaticResource yourTemplateSelector}" />
