WPF bind TextBlock "text" in one user control to textbox in another UserControl Where both of them are hosted in a Frame inside mainWindow

SUMMARY OF THE PROBLEM:
I have main window which has a frame and a button, in the frame i'm going to show one user control at a time (i provided an image of my usercontrol).
in the first UserControl, i will write 4 player names (two for each team).
after i press the button and i go to next usercontrol i want to show the names of the players in textblock. I also want to bind IsChecked property of radio button in first UserControl to the second UserControl. (i have other buttons that show up in mainWindow depends on what usercontrol is in the Frame right Now)
WHAT I TRIED:
I tried binding the textbox property to the textblock in the second usercontrol but it doesnt show or i cant access it.
because i have the button in the mainWindow i tried saving the names in variable then pass it to next usercontrol but didnt work also.
Also tried alot of random online solution i found online but nothing worked.
i need a way to expose the property of First UserControl to be used in the Second UserControl

How to use one Page object in multiple Frames in another Page?

I want to have a Page object, that contains Frames, that contain another Page. The current result looks like that:
But I want the Page to be appear in all of the Frames.
How can I achieve that?
The page that contains Frames:
public partial class CombinedPage : Page
{
public CombinedPage()
{
InitializeComponent();
Frame1.Content = MainWindow.testPage;
Frame2.Content = MainWindow.testPage;
Frame3.Content = MainWindow.testPage;
Frame4.Content = MainWindow.testPage;
}
}
XAML:
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<GridSplitter Grid.Column="1" Grid.RowSpan="3" Width="5" Background="Black"
VerticalAlignment="Stretch" HorizontalAlignment="Center" />
<GridSplitter Grid.Row="1" Grid.ColumnSpan="3" Height="5" Background="Black"
VerticalAlignment="Center" HorizontalAlignment="Stretch" />
<Frame NavigationUIVisibility="Hidden" x:Name="Frame1" Grid.Row="0" Grid.Column="0"/>
<Frame NavigationUIVisibility="Hidden" x:Name="Frame2" Grid.Row="0" Grid.Column="2"/>
<Frame NavigationUIVisibility="Hidden" x:Name="Frame3" Grid.Row="2" Grid.Column="0"/>
<Frame NavigationUIVisibility="Hidden" x:Name="Frame4" Grid.Row="2" Grid.Column="2"/>
</Grid>
The TestPage XAML:
<Grid>
<Viewbox Stretch="Uniform" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Label Name="LiveTimeLabel" Content="%TIME%" HorizontalContentAlignment="Stretch" HorizontalAlignment="Stretch" Foreground="#cccccc" VerticalAlignment="Stretch" FontWeight="Bold" />
</Viewbox>
</Grid>
Thanks for any advice!
EDIT 1: Ok, then if I can use Page object only once, then how change it's location from one frame to another? I tried this, but it doesn't seem to be work:
public partial class CombinedPage : Page
{
public CombinedPage()
{
InitializeComponent();
Frame1.Content = MainWindow.testPage;
Frame2.Content = MainWindow.testPage;
Frame3.Content = MainWindow.testPage;
Frame4.Content = MainWindow.testPage;
}
private void butt1_Click(object sender, System.Windows.RoutedEventArgs e)
{
Frame1.Content = MainWindow.testPage;
}
private void butt2_Click(object sender, System.Windows.RoutedEventArgs e)
{
Frame2.Content = MainWindow.testPage;
}
private void butt3_Click(object sender, System.Windows.RoutedEventArgs e)
{
Frame3.Content = MainWindow.testPage;
}
private void butt4_Click(object sender, System.Windows.RoutedEventArgs e)
{
Frame4.Content = MainWindow.testPage;
}
}
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
<RowDefinition/>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<GridSplitter Grid.Column="1" Grid.RowSpan="3" Width="5" Background="Black"
VerticalAlignment="Stretch" HorizontalAlignment="Center" />
<GridSplitter Grid.Row="1" Grid.ColumnSpan="3" Height="5" Background="Black"
VerticalAlignment="Center" HorizontalAlignment="Stretch" />
<Frame NavigationUIVisibility="Hidden" x:Name="Frame1" Grid.Row="0" Grid.Column="0"/>
<Frame NavigationUIVisibility="Hidden" x:Name="Frame2" Grid.Row="0" Grid.Column="2"/>
<Frame NavigationUIVisibility="Hidden" x:Name="Frame3" Grid.Row="2" Grid.Column="0"/>
<Frame NavigationUIVisibility="Hidden" x:Name="Frame4" Grid.Row="2" Grid.Column="2"/>
<StackPanel Grid.Row="3" Grid.Column="0" Orientation="Horizontal">
<Button x:Name="butt1" Width="50" Click="butt1_Click"/>
<Button x:Name="butt2" Width="50" Click="butt2_Click"/>
<Button x:Name="butt3" Width="50" Click="butt3_Click"/>
<Button x:Name="butt4" Width="50" Click="butt4_Click"/>
</StackPanel>
</Grid>

You should create separate instance of the same Page class:
public CombinedPage()
{
InitializeComponent();
Frame1.Content = new TestPage();
Frame2.Content = new TestPage();
Frame3.Content = new TestPage();
Frame4.Content = new TestPage();
}
A single instance of a control can only appear once in the visual tree so you cannot display the same page instance in more than one Frame.

Converting FrameworkElement to Jpeg in UWP

At the past, I can convert and save an usercontrol to an JPEG image with this code:
private string CreateBitmapImage(FrameworkElement usefulData, string name) // Tekli görev kartını masaüstünde oluşturmak için, resim yaratma fonksiyonu.
{
try
{
string fullFileName = string.Empty;
Size size = new Size(642, 416);
usefulData.Measure(size);
usefulData.Arrange(new Rect(size));
var rtb = new RenderTargetBitmap((int)usefulData.ActualWidth, (int)usefulData.ActualHeight, 96, 96, PixelFormats.Pbgra32);
rtb.Render(usefulData);
var encoder = new JpegBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(rtb));
SaveFileDialog dlg = new SaveFileDialog();
dlg.Title = "Görev kartını nereye kaydetmek istersiniz ?";
dlg.FileName = name; // Default file name
dlg.DefaultExt = ".jpg"; // Default file extension
dlg.Filter = "Resim Dosyası (.jpg)|*.jpg"; // Filter files by extension
dlg.OverwritePrompt = true;
var result = dlg.ShowDialog();
if (result == true && dlg.CheckPathExists == true)
{
fullFileName = System.IO.Path.Combine(dlg.FileName);
using (var filestream = new FileStream(fullFileName, FileMode.Create))
{
encoder.Save(filestream);
}
}
return fullFileName;
}
catch
{
MessageBox.Show("Tek görev kartını yaratırken bir hata oluştu.Lütfen yeniden deneyin.", "Hata", MessageBoxButton.OK, MessageBoxImage.Error);
return "";
}
}
Now, I'm converting my WPF project to UWP. However, I cannot find how I convert and save an usercontrol to an Jpeg image in UWP. Can you help me please ?
Thanks.

It is the code how I create an instance from my user control:
var item = new TaskCard(Name_TextBox.Text.ToUpper() + " " + Surname_TextBox.Text.ToUpper(), Task_TextBox.Text, ExamArea_TextBox.Text, HallName_TextBox.Text,HallNumber_TextBox.Text,DateConverter.Get(Date_Picker.Date.ToString())); // Creating card.
RenderTargetBitmap renderTargetBitmap = new RenderTargetBitmap();
await renderTargetBitmap.RenderAsync(item); // Gives error here.
var pixelBuffer = await renderTargetBitmap.GetPixelsAsync();

For converting, UWP app also has RenderTargetBitmap class for capturing a UIElement as an image source. For file saving, you could reference this turtorial. In UWP app we have FileSavePicker which is similar to SaveFileDialog. For example, a completed demo as follows:
RenderTargetBitmap renderTargetBitmap = new RenderTargetBitmap();
await renderTargetBitmap.RenderAsync(elementToRender, 642,416);
var pixelBuffer = await renderTargetBitmap.GetPixelsAsync();
var savePicker = new FileSavePicker();
savePicker.DefaultFileExtension = ".png";
savePicker.FileTypeChoices.Add(".png", new List<string> { ".png" });
savePicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
savePicker.SuggestedFileName = "snapshot.png";
// Prompt the user to select a file
var saveFile = await savePicker.PickSaveFileAsync();
// Verify the user selected a file
if (saveFile == null)
return;
// Encode the image to the selected file on disk
using (var fileStream = await saveFile.OpenAsync(FileAccessMode.ReadWrite))
{
var encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.PngEncoderId, fileStream);
encoder.SetPixelData(
BitmapPixelFormat.Bgra8,
BitmapAlphaMode.Ignore,
(uint)renderTargetBitmap.PixelWidth,
(uint)renderTargetBitmap.PixelHeight,
DisplayInformation.GetForCurrentView().LogicalDpi,
DisplayInformation.GetForCurrentView().LogicalDpi,
pixelBuffer.ToArray());
await encoder.FlushAsync();
}
More details you could reference the official XAML render to bitmap sample.
Update:
Also add the XAML code section which use a UserControl for testing. What pass to the RenderAsync method should be the name of the Element you want to render.
<local:MyUserControl
x:Name="elementToRender"
Width="100"
Height="150" />

I did some researches why I can't render a TargetBitmap from code. I found a reason at this link:
You cannot save visual element which in code (offscreen) to image.
So, I foluna a new way to render my code based user control. I created my user control via code like this:
//Initializing task card.
var item = new TaskCard(Name_TextBox.Text.ToUpper() + " " + Surname_TextBox.Text.ToUpper(), Task_TextBox.Text, ExamArea_TextBox.Text, HallName_TextBox.Text, HallNumber_TextBox.Text, DateConverter.Get(Date_Picker.Date.ToString())); // Creating card.
After this, I added a custom popup-like element with this:
<Border x:Name="RingBorder" Margin="0,0,0,0" HorizontalAlignment="Center" VerticalAlignment="Center" BorderBrush="{ThemeResource SystemControlBackgroundBaseHighRevealBorderBrush}" BorderThickness="2,2,2,2" RequestedTheme="Default" Visibility="Collapsed" >
<Grid x:Name="InnerGrid_Ring" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" RequestedTheme="Default" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
<Grid x:Name="WaiterRing_SecondRow" HorizontalAlignment="Stretch" Margin="0,0,0,0" VerticalAlignment="Stretch" Grid.Row="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock x:Name="LoadValue_Ring" Text="Lütfen bekleyin..." TextWrapping="Wrap" FontWeight="Normal" Margin="10,0,10,0" TextAlignment="Center" VerticalAlignment="Center" HorizontalAlignment="Stretch" Grid.Column="1" Style="{StaticResource TitleTextBlockStyle}" />
<ProgressRing x:Name="Waiter_Ring" HorizontalAlignment="Center" Margin="10,10,10,10" VerticalAlignment="Center" Foreground="{StaticResource AndroidGreen}" IsActive="True" Width="40" Height="40"/>
</Grid>
<Grid x:Name="CardViewerGrid_Ring" HorizontalAlignment="Center" Height="416" Margin="0,0,0,0" VerticalAlignment="Center" Width="642"/>
</Grid>
</Border>
Lastly, I'm rendering the user control like this:
//Converting UIelement to Rendered Bitmap
CardViewerGrid_Ring.Children.Add(item); // Adding card to canvas.
RenderTargetBitmap renderTargetBitmap = new RenderTargetBitmap();
await renderTargetBitmap.RenderAsync(CardViewerGrid_Ring); // Render canvas.
var pixelBuffer = await renderTargetBitmap.GetPixelsAsync();
And, voila :)

How to assign List<> Object values to textBox (s)

I want to assign the values of the findFamily object to the different TextBox(s) i tried the following code but it's not working would you please suggest me a better way. Thanks in advance.

List<Family> findFamily = (from s in con.Families where s.FamilyMemberId.Equals(SearchFamilyMemberId.Text.Trim()) select s).ToList();
if (findFamily.Any())
{
FamilyMemberId.Text = findFamily[0];
FirstName.Text = findFamily[1];
LastName.Text = findFamily[2];
if (findFamily[3]=="Male")
{
Male.IsChecked = true;
}
else

Why don't you use data binding?
For each of the text boxes that you have, bind your TextBox.Text to its corresponding property in the view model, something like this:
<TextBox Text={Binding FirstName} />
Then, assign your FirstName, LastName...etc. properties to values and raise INotifyPropertyChanged.PropertyChanged for each of the properties (your view model should implement INotifyPropertyChanged) and your view (i.e. UI) should get updated.

I don't agree with any of the answers posted here. The question doesn't seem to be correct.
If you have a list of Family members. Then how can you show it as a single item. How do you know which item you want to display.
Hence my suggestion is to use a listbox and using data binding, create a view to display the current selected Family member's data in that view.

use foreach loop through list as:
foreach(var a in findFamily)
{
txtbox.text=a[0].tostring();
txtbox2.text=a[1].tostring();
}
or use:
txtbox.text = findFamily.Select(a => a[0].ToString()).FirstOrDefault().ToString();

How to change a grid layout when orientation is changed

I'm creating a win8 app and I need to change the layout of my grid so everything fits on screen when the user flips between orientations. I understand I need to use VisualStateManager but I can't understand any tutorials. If I have this code:
<Grid>
<Button x:Name="button1" Margin="188,73,286,0" VerticalAlignment="Top"/>
<Button x:Name="button2" Margin="236,73,238,0" VerticalAlignment="Top"/>
<Button x:Name="button3" Margin="284,73,190,0" VerticalAlignment="Top"/>
</Grid>
How would I use visual state manager to change the buttons so they are now orientated in a column (one above the other) instead of in a row when the orientation is changed to portrait from landscape?
Thanks
