Display text with a string in Textblock xaml - wpf

Question

I have a textblock, and I want to display a text with a defined string. How to do it?
The textblock:
<TextBlock HorizontalAlignment="Left" TextWrapping="Wrap" Padding="6" VerticalAlignment="Center" Margin="45,0,0,0" Height="30" Width="386" Text="My Program ver. Version"/>
My string:
Public Version As String = "1.0a"

Answer 1

You can use StringFormat.
<TextBlock Text="{Binding Path=Version, StringFormat=My Program ver. {0}}" />
In your code- behind you must change Version to property (this property should be ReadOnly because it isn't change in runtime) and assign DataContext in constructor:
Class MainWindow
Public Sub New()
InitializeComponent()
Me.DataContext = Me
End Sub
ReadOnly Property Version As String
Get
Return "1.0a"
End Get
End Property
End Class

Answer 2

If you want your TextBlock to update the version number every time you have a new version,
you can do it like this in C#. You can probably find out easily how to write this in VB.
This will update your TextBlock everytime you publish a new version of your program.
In XAML you bind a TextBlock text to "Version":
<TextBlock Text="{Binding Version, Mode=OneWay}" />`
And then in code-behind or in your view-model you can use a property for that Binding that you have in the XAML TextBlock:
public string Version
{
get
{
return String.Format("VERSION: {0}",DeploymentInfo.Version.ToString());
}
}
Then you need to add a reference to "System.Deployment" in your project.
This will only work when you have done a "PUBLISH" of your project. When you start the debugger you will probably only see version number: 0.0.0.0

In XAML file:
First you should name your TextBlock i have gave tbWithNoName for example.
<TextBlock x:Name="tbWithNoName" HorizontalAlignment="Left" TextWrapping="Wrap" Padding="6" VerticalAlignment="Center" Margin="45,0,0,0" Height="30" Width="386" Text="My Program ver. Version"/>
Then add Loaded call on Window object.
<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525"
Loaded="Window_Loaded">
Insert Window_Loaded function to your vb file.
Private Sub Window_Loaded(sender As Object, e As RoutedEventArgs)
tbWithNoName.Text = tbWithNoName.Text + " " + Version
End Sub
This will change TextBlock's Text when Window loaded
