*i want to upload it in specfic folder and then download it on my system*... this is a terrible description of your requirements. After displaying the selected file path, what exactly do you want to do? — Sheridan, Jun 03 '14 at 07:59

Frankly, to me the code looks okay, so it's strange that it doesn't work. Having said that, I'd suggest that you take a different approach. You are using WPF, which is very good at data binding. If you in the code behind define a property

private string _fileName;
public string FileName
{
 get{return _fileName;}
 set{
  _fileName = value;
  OnPropertyChanged("FileName");
}

The implementation of OnPropertyChanged and a simple explanation of INotifyPropertyChanged can be found at http://www.java2s.com/Tutorial/CSharp/0470__Windows-Presentation-Foundation/RaisethePropertyChangedevent.htm

In your XAML, you already have a TextBlock which should be extended with a binding

TextBlock x:Name="tb_file" Text="{Binding Path=Filename}"

To ensure that the binding to a property in the code behind works, please refer to Binding objects defined in code-behind

Hope that helps (at least the first part of your question)

@user3667841, if this answer has helped you to solve your problem, then please [accept it](http://stackoverflow.com/help/accepted-answer), as is customary on this website. — Sheridan, Jun 11 '14 at 08:43
