The idea was to have a TextBlock in the view and only have its visibility property set to

问题 In Windows Store Apps, you create a user control to encapsulate and reuse code-behind and layout XAML. A simple user control might look like this: <UserControl> <StackPanel> <TextBlock Text="First Name" /> <TextBox x:Name="MyTextBox" /> </StackPanel> </UserControl> Now, I want to setup binding. So I create code-behind with properties that expose the Text properties of the UI controls. Something like this: public string TextBoxText { get { return MyTextBoxText.Text; } set { MyTextBoxText.Text
