<TextBlock Height="231" Canvas.Left="120" TextWrapping="Wrap" Canvas.Top="459" Width="840"
FontFamily="Neo Sans Pro" FontSize="48"
Foreground="#FF006CB7"
VerticalAlignment="Top" HorizontalAlignment="Left" TextAlignment="Center">
<Run Text="Для перечисления "/>
<Run FontWeight="Bold" Text="AMOUNT"/>
<Run Text=" рублей в помощь детям с помощью банковской карты, пожалуйста, следуйте инструкции:"/>
</TextBlock>
What you need is a binding to a variable in your code-behind.
Text="{Binding AMOUNT}"
If this is - as you describe - a "global variable", you can bind like so:
Text="{x:Static wpfApplication1:Globals.Amount}"
The global variable definition could look like this:
public class Globals
{
public static string Amount = "5000";
}
Note that the Text property of your text box requires a string.
Using MVVM; in very broad strokes :
Create a class with a string property: eg
public class MyViewModel { public string Amount { get { return "..."; } } }
Assign an instance of the class above to the DataContext of the view.
var viewModel = new MyViewModel(); view.DataContext = viewModel;
Using a binding expression in the XAML
...TextBlock Text="{Binding Amount}"... />
