Question

I have a textbox and a button in my .xaml. When i click the button i am able to open a filedialog and able to select the file as well.

MainWindow.Xaml:

<TextBox Height="93" IsReadOnly="True" Text="{Binding Path=ReadMessage, Mode=TwoWay}" Name="MessageRead" />

<Button Content="Load" Name="I2CLoadBtn" Command={Binding Path = LoadContentCommand />

My ViewModel Class:

public static RelayCommand LoadContentCommand { get; set; }

    private string _ReadMessage;
    public string ReadMessage
    {
        get { return __ReadMessage; }
        set
        {
            __ReadMessage= value;
            NotifyPropertyChanged("ReadMessage");
        }
    }

    private void RegisterCommands()
    {
        LoadContentCommand = new RelayCommand(param => this.ExecuteOpenFileDialog());
    }

    private void ExecuteOpenFileDialog()
    {
        var dialog = new OpenFileDialog { InitialDirectory = _defaultPath };
        dialog.ShowDialog();
        dialog.DefaultExt = ".bin";
        dialog.Filter = "Bin Files (*.bin)|*.bin";           
    }

What i basically want is, once the file is selected, the contents of the file must be saved into the textbox. E.g. If I have a .txt file to be loaded, on loading the contents must get placed inside the textbox.

Please help!!!

This is how you get the selected path:

string path = "";
if (dialog .ShowDialog() == true)
{
    path = dialog.FileName;
}

using (StreamReader sr = new StreamReader(path)) 
{
     ReadMessage = sr.ReadToEnd()
}
