Tab Key does not work when focused
                            
                         
                        
                     
                 
                
                    Hello,
I've coded a new TextBox control like below.
public class DecTextBox : TextBox
{
}
Every thing is working well in my control except for tab key. When the my control focused i cannot go to the next or previous controls by pressing tab and shift-tab keys.
is there anyone who had experienced this issue before.
