I thought to use the event TextChanged, detaching and attaching again(durring color changes)
Any other better idea ?
void rTBOnContentChanged(.....)
{
//bellow I will not change the content of the richTextBox
....................
// here I want to have FULL UPDATED the content of the richTextBox
....................
rTB.TextChanged -= new EventHandler(rTBOnContentChanged)
// here I make changes to its color
....................
rTB.TextChanged += new EventHandler(rTBOnContentChanged)
}
