multi lines on a text box[resolved]

[Sneeden]

I must be retarded. I need to write progress to a text box. One line after the other. I have the multiline property to true, but I cannot get newline escape char to do anything.

private....()
{
	addText("parsing signals");
	addText("finished parsing signals");
	//etc...
}

private void addText(String iText)
{
	txtProgress.Text=txtProgress.Text+iText+"...\n";
}

It outputs to the textbox:
reading file...finished reading file...parsing signals...finished parsing signals...

Instead of:
reading file...
finished reading file...
parsing signals...
finished parsing signals...

However, when I copied and pasted the output into this page, it had the \n chars put in.

Is there some other property on the text box that I need to set?
