Question

I have my Model as:

namespace Forecast.MVVM.WPF.ViewModel
{
    public class ApplicationInfoViewModel
    {
       private string versionNumber;
       public ApplicationInfoViewModel()
        {
          versionNumber = Assembly.GetExecutingAssembly().GetName().Version.ToString();
        }
       public string VersionNumber
        {
            get { return versionNumber; }
            set { versionNumber = value; }
        }
}

And my view I am setting the datContext and getting the values as ;

<UserControl .... xmlns:AppInfo="clr-namespace:Forecast.MVVM.WPF.ViewModel" .../>
 <UserControl.Resources>
        <AppInfo:ApplicationInfoViewModel x:Key="forecastVersionInfo"/>
    </UserControl.Resources>
<Grid>
<TextBlock Grid.Row="1" Grid.Column="1" Text="{Binding VersionNumber}" VerticalAlignment="Bottom"/>
</Grid>

But I am unable to see the values

Answer 1

1st way :

Try tro replace <UserControl.Resources> by <UserControl.DataContext>
… and delete “x:Key="forecastVersionInfo"“.

2nd way :
Or set DataContext="{StaticResource forecastVersionInfo}" on your textBlock.

3rd way :
According to this MSDN page, set the Source property on your textblock binding :

Text="{Binding VersionNumber, Source={StaticResource forecastVersionInfo}}"
