How to Pass data from one UserControl1 to UserControl2 from a button in UserControl1 WPF MVVM

I recently started studying about User Controls. I have a Main Window which contains this 2 User Controls. UserControl1 is a form to get the data, and when the submit button is clicked in UserControl1, the UserControl2 will be visible viewing the data send from the UserControl1.
Here is my MainWindow xaml (HomeCareMain.xaml)

</UserControl>
This is the Button Command of the UserControl1 in its ViewModel
#region Handlers : Commands
private void OnPreviewCommandExecute()
{
PatientRecordDetailsModel getPatientDetails = PopulatePatientDetails();
}
I didn't put the whole code inside the ViewModel since it's too long.
PatientRecordDetailsModel is the model object that will be sent to the UserControl2.
Inside the UserControl2 ViewModel constructor it binds the data with the userControl View.
class PrintPreviewViewModel
{
#region Fields
private IWindowService m_windowService;
private PatientRecordDetailsModel patient;
#endregion
#region Constructors
public PrintPreviewViewModel(PatientRecordDetailsModel patient)
{
this.patient = patient;
PatientID = patient.PatientId;
PatientRegisteredDate = patient.PatientRegisteredDate;
PatientName = patient.PatientName;
PatientAddress = patient.PatientAddress;
PatientGender = patient.PatientGender;
PatientDateOfBirth = patient.PatientDateOfBirth.ToShortDateString();
PatientAge = patient.PatientAge;
PatientImageSource = patient.PatientImageSource;
PatientDepartment = patient.PatientDepartment;
PatientWard = patient.PatientWard;
PatientDotorcInCharge = patient.PatientDoctorInCharge;
m_windowService = new WindowService();
}
}
Inside the HomeCareMain.xaml.cs file I defined a method called PrintPreviewButtonClicked() to bind the data to the UserControl2's DataContext and to Visible it.
public partial class HomeCareMain : Window
{
public HomeCareMain()
{
InitializeComponent();
this.DataContext = new HomeCareMainViewModel();
PatientRecordDetailsViewModel patientRecordDetailsViewModel = new PatientRecordDetailsViewModel();
AddPatient.DataContext = patientRecordDetailsViewModel;
AddPatient.Visibility = Visibility.Hidden;
PrintPreview.Visibility = Visibility.Hidden;
}
public void PrintPreviewButtonClicked(PatientRecordDetailsModel patient)
{
PrintPreview.DataContext = new PrintPreviewViewModel(patient);
PrintPreview.Visibility = Visibility.Visible;
}
}
The problem is I want to send the PatientRecordDetailsModel object to the HomeCareMain.xaml.cs without violating MVVM architecture.
Or is there an alternative way of doing this.
I have used separate viewModels for user controls and the main window since they have their own responsibilities to perform.
I really hope you could help me with this.

You should either bind to the same view model from both UserControls, or use an event aggregator or messenger to send an event or a message from one component to another in a loosely coupled way as explained in this blog post.
If you don't use a framework, you'll have to implement the event aggregator yourself.

How to find dropped source in wpf

My problem is simple, I want my images to have the same behaviour of a button when the user touches them. They simply have to "move back" and then come forward again exactly as the animation of touching a simple button.
It is ok even if only the image is moving like that, but I don't really know how to achieve this, any help will be really appreciate.
Thanks all and sorry for my bad english, if you need some more infos tell me

You should use GridColumns and GridRows property of Grid control for you XAML. You have problem with resolution, because you hardcode margins of you TextBlocks. You should write:
<Grid>
<Grid.RowDefinitions>
<RowDefition />
......
</Grid.RowDefinitions/>
<Grid.ColumnDefinitions>
....
</Grid.ColumnDefiniti‌​ons/>
.....
</Grid>
And after insert your TextBlock to need column and row, for ex.:
<TextBlock Grid.Row="1" Grid.Column="1" />

Can anyone tell me where is the problem.Any help would be highly appreciable.

It seems that one of the StaticResources used does not exist:
Either:
AddHwType (Button Style)
AppButtons (Button Style)
BooleanToVisibilityConverter (Converter)
You might miss a merged dictionary somewhere or forgot to add a resource before using it. Review the XAML Resources page on MSDN for more info.

Solved:I was using wrong Static Resource i was writingStyle="{StaticResource AddHwType }" and it should be Style="{StaticResource AppButtons}" :)
