Question

I’m creating a wpf user control which is in mvvm pattern.
So we have : view(with no code in codebehind file), viewmodel,model,dataaccess files.

I have MainWindow.xaml as a view file, which I need to bind with MainWindowModel.cs.

Usually, in a a wpf application we can do this with onStartUp event in App.xaml file. But in user control, as we do not have App.xaml…How do I achieve it ?

Please help :(…Thanks in Advance !!!

You can use a ContentControl, with a DataTemplate to bind the UserControl (View) to the ViewModel :

<DataTemplate DataType="{x:Type vm:MyViewModel}">
    <v:MyUserControl />
</DataTemplate>

...

<ContentControl Content="{Binding Current}" />

WPF will pick the DataTemplate automatically based on the type of the Content
