how to set text color in RichTextBox

[tsahiasher]

hi,
i'm trying to use the RichTextBoxSele ctionColor property, but in any
combination of command order i try, the text color is not changed. the
only time it worked was when i set SelectionStart = 0.

here's one version i tried:

String res = "Failed";
int selectionStart = rtbTestResult.T extLength;
rtbTestResult.A ppendText(res + Environment.New Line);
// OR rtbTestResult.T ext += res + Environment.New Line;
rtbTestResult.S electionStart = selectionStart;
rtbTestResult.S electionLength = res.Length;
rtbTestResult.S electionColor = Color.Red;

any ideas?

Hi,

I am unable to verify your problem. Your code works as expected. The
word Failed is appended to whatever text is present, and the word is
indeed colored red.

If you open a new project, using only the RichTextBox, do you still get no
color?

i get it in black. can it be related to the fact that subsequent calls
to this method add more text to the richtextbox, in another case block?
(the code above is in a case block of a switch statement).

i tried to make a simple app, where i preloaded the textbox with lorem
ipsum, and on a button click event i did SelectionColor = Color.Red,
and indeed any text i selected with the mouse was painted red. in this
case, however, rtbTestResults. ReadOnly = true.

while writing this post i tried to set HideSelection = false, and
"Failed" blinked in red for a moment, but when more text was added, it
turned black again.

i fixed it. i replaced all calls to Text += "some string" to
AppendText("som e string"), and it works. it must be something with this
+= operator.

I don't think using AppendText instead of += is the reason you got black
text. More likely you overwrote the red text with black at a later point.

Glad to see it works now, though.
