Hi
I created a component and define a little property like this

public int Valueint
{
  get
  {
    return Convert.ToInt32(someText.Text) ;
  }
  set
  {
    sometext.Text = value.ToString(); 
  }
}

when I Use my component on a form and go to propety form an DataBinding then advance
and set the ValueInt property to a field of some bindingsource
then every time I change the current row , Datatable.getchanged returns that some record has been changed . I found that my component and Valueint property made this problem I want to khnow how can I control the component that said datatable its value has not been changed ? thanks
