I'm trying to bind a Textbox.Text to Form.Text (which sets the title of the form). The binding itself works. But, the title isn't updated until I move the entire form.

How can I achieve Form.Text being updated without moving the form? I'd like Form.Text being updated directly when I type something in the Textbox.

Edit; I set the title of the Form in a TextChanged event which is fired by a ToolStripTextbox:

public partial class ProjectForm : Form
{
   public ProjectForm()
   {
       // my code contains all sorts of code here, 
       // but nothing that has something to do with the text.
   }
}

private void projectName_TextChanged_1(object sender, EventArgs e)
{
    this.Text = projectName.TextBox.Text;
}

And the Databinding version:

public partial class ProjectForm : Form
{
   public ProjectForm()
   {
       this.projectName.TextBox.DataBindings.Add("Text", this, "Text", true, DataSourceUpdateMode.OnValidation);
   }
}

Edit 2: I see I forgot to mention something. Don't know if it adds anything, but my apllication is a MDI application. The part of the title that changes is:

ApplicationName [THIS CHANGES, BUT ONLY AFTER MOVING/RESIZING]
