I have a WPF Application which is using MVVM.
I know that there ways of doing this in XAML but I am working on a plugin architecture and came up with a solution where a plugin exposes it's viewmodel to my plugin host's viewmodel and it's datatemplate. I want to leave the lifetime management of the plugin view up to WPF. I have tried having the plugins expose a UserControl but ran into issues when WPF decided to dispose of my UserControl so I would not reattach it without weird hacky work arounds. I am having issues getting some sort of binding working to where i can bind a control to the data and it's template to my data template.
I have a ViewModel which looks something like:
public class MyViewModel
{
public DataTemplate SelectedTemplate{ get; set;}
public object SelectedViewModel {get; set;}
}
The selected template and viewmodel are determined somewhere else in the code but are irrelevant to my question.
My question is how i can bind to a DataTemplate so that I know how to display the data shown in the SelectedViewModel.
The DataTemplate is a DataTemplate created incode which respresents:
<DataTemplate DataType="{x:Type vm:MyViewModel}">
<v:MyUserControl />
</DataTemplate>
I have tried:
<UserControl Template="{Binding Path=SelectedTemplate}"
Content="{Binding Path=SelectedViewModel"} />
But UserControl expects a control template and not a data template.
