This class, derived from the standard TextBox control, is used by the DataGridTextBoxColumn to support the editing of column text. You can access the DataGridTextBox for a specific column by using the DataGridTextBoxColumn.TextBox property. You could then hook the text box for validation, for example.

public class DataGridTextBox : TextBox {
// Public Constructors
   public DataGridTextBox();
// Public Instance Properties
   public bool IsInEditOrNavigateMode{set; get; }
// Public Instance Methods
   public void SetDataGrid(DataGrid parentGrid);
// Protected Instance Methods
   protected override void OnKeyPress(KeyPressEventArgs e);  // overrides Control
   protected override void OnMouseWheel(MouseEventArgs e);  // overrides Control
   protected internal override bool ProcessKeyMessage(ref Message m);  // overrides Control
}
