DataBinding issue

[GDavy]

Hello people, I have the following problem. I have a class with a property like in the below example:

class myClass:INotifyPropertyChanged
{
private string theProp;

public string TheProp
{
get{ return theProp; }
set
{
if( string.IsNullOrEmpty(value) )
theProp = "Another Value";
else
theProp = value;
NotifyPropertyChanged("TheProp");
}
}
/// And a lot of other stuff
}

So in case an empty or null is set I set the internal value of the property to a default string. The object is doing this just fine. But the problem I have is with a textBox that is bound to this property. When I delete the text in the textbox, the textbox does not represent the different value. Probably I'm doing something wrong with the binding, it seems like a common way to set a different value, so I suppose there must be a way to make this work. thanks for any help you might provide. Davy

public partial class Form1 : Form
{
myClass o = new myClass();

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1\_Load(object sender, EventArgs e)
    {
        this.textBox1.DataBindings.Add("Text", o, "TheProp", false, DataSourceUpdateMode.OnPropertyChanged, string.Empty);
    }
}

class myClass : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private string theProp;
    public string TheProp
    {
        get { return theProp; }
        set
        {
            if (string.IsNullOrEmpty(value))
                theProp = "Another Value";
            else
                theProp = value;
            NotifyPropertyChanged("TheProp");
        }
    }
    private void NotifyPropertyChanged(String info)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(info));
        }
    }

}

Thanks! It works like a charm now... I had set the databinding via the Visual Studio GUI using a BindingSource. Apparantly it doesn't set the parameters exactly the same way. Setting the binding myself the way you showed made it work. Greetings, Davy
