[Karthik]

Hi Telerik,
I trying to update some text to RadRichTextBox but it's work. It showing me a blank screen. If i use windows/winform richtextbox it works.

What shouild i do???  Thank you.

exBuilder.Clear();
                exBuilder.Append(exception.Message + Environment.NewLine);

                RadRichTextBox richTextBox = new RadRichTextBox();
                //RichTextBox richTextBox = new RichTextBox();
                richTextBox.ThemeName = "Office2007Black";

                richTextBox.Text =  line + ":" + exBuilder.ToString();
                richTextBox.Dock = DockStyle.Fill;
                richTextBox.IsReadOnly = true;
                //richTextBox.ReadOnly = true;
                richTextBox.ForeColor = Color.Red;

Sorry Telerik, found solution:  richTextBox.Insert(line + ":" + exBuilder);
