richtextbox

We tried several ways to make a textbox to accept the "enter", newline, etc.. But we are still facing the same problems. Most of the "Third party" controls allow the user to format the text as he wants. Eg, add color, font, table, etc.. However, for most stylish websites, we do not want to allow the user to format the text that way. But we still want them to make "enter", so we disable most functions (Colors, bold, table, insert image, etc.). But we still have another problem, copy and paste. It is not uncommon to see people that copy from MS Word in the textbox and wham, all the style of the

I have a Winforms app containing a RichTextBox. How can I determine how many lines of text are displayed, currently visible? Reason: I want to scroll the caret to the middle of the RichTextBox. I can use RichTextBox.ScrollToCaret() , but that puts the caret at the top of the RichTextBox. I figure, If I know how many lines are displayed, I could move the caret "back" n/2 lines, then call ScrollToCaret(), then restore the original caret position. EDIT: I found EM_GETLINECOUNT , which I thought was the answer, except the doc says: The EM_GETLINECOUNT message retrieves the total number of text

I have several read only RichTextBox's that are used for logging output. Since they're read only they don't seem to automatically scroll when the text is updated. I can use the TextChanged event to force a scroll to end, but is there not simply a way to set a property or something in the XAML so that scrolling happens like normal? I had googled for your problem and found this post. In the section "Programming the RichTextBox" author had described about getting the behavior what you had been expecting. Please check and let me know if it is of any use. I tried to reproduce your problem and came

I have a WinForms application with a RichTextBox control on the form. Right now, I have the AcceptsTabs property set to true so that when Tab is hit, it inserts a tab character. What I would like to do though is make it so that when Tab is hit, 4 spaces are inserted instead of a \t tab character (I'm using a monospaced font). How can I do this? Add a new class to override your RichTextBox : class MyRichTextBox : RichTextBox { protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if(keyData == Keys.Tab) { SelectionLength = 0; SelectedText = new string(' ', 4); return true; }

I currently have a function that will set a value to a RichTextBox, although how could you "add" a value or a new line to it, rather than overwriting existing data in the RichTextBox? richTextBox2.Text = DateTime.Today + " Hello"; agent-j richTextBox2.AppendText(Environment.NewLine + DateTime.Today + " Hello"); richTextBox2.AppendText(String.Format("{0} the date is {1}{2}", "Hello", DateTime.Today, Environment.NewLine)); Please don't use + richTextBox2.Document.Blocks.Clear(); richTextBox2.Document.Blocks.Add(new Paragraph(new Run("string"))); richTextBox2.Text = "Something " + richTextBox2
