Reference the View from ViewModel while using DataTemplate for the ViewModel

i'm using a DataTemplate to provide the association of View to ViewModel, for example:

<DataTemplate DataType="{x:Type viewModels:SomeViewModel}">
    <views:SomeView />
</DataTemplate>

now i need to reference the View somehow in my ViewModel, so i could reference some control directly by its name. Is there anyway to do that?

Note i already tried to add a SomeView parameter to the SomeViewModel Ctor but than the SomeView Ctor is being invoked twice(one for the instance i sent to the SomeViewModel Ctor and the because of the framework i guess...)

thanks for your help

Maybe this is what you're looking for:

public partial class SomeView : UserControl
{
    public SomeView()
    {
        InitializeComponent();
        this.Loaded += View_Loaded;
    }

    void SomeView_Loaded(object sender, RoutedEventArgs e)
    {
        var someViewModel = (SomeViewModel)this.DataContext;
        someViewModel.View = this;
    }
}
