Question

I hv a richTextBox in Windows Appliction form (C#).
it has some text say:123456789 of black forecolor.
On some event, I make the part of text (say:123) to Red Forecolor and on other event I make it Undo. (Now,again all are black)

Now the problem is that, when I select 12345, it doesnt recognise the selected color(IsknownColor=false). but if I select the text seperately (say: 123 and 45) . It gives IsknownColor=True

Instead of checking on: SelectedColor.
I hv use following:

C#

if (RichTextBox1.SelectedRtf.Contains("red255"))
                {                    
        MessageBox.Show("Please do not select the already selected text!!");
                    return;
                }
