由 别等时光非礼了梦想. 提交于 2019-12-19 04:14:32
问题 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"; 回答1: richTextBox2.AppendText(Environment.NewLine + DateTime.Today + " Hello"); 回答2: richTextBox2.AppendText(String.Format("{0} the date is {1}{2}", "Hello", DateTime.Today, Environment.NewLine)); Please don't use + 回答3: richTextBox2.Document.Blocks.Clear();

How do I move the caret a certain number of positions in a WPF RichTextBox?

由 …衆ロ難τιáo~ 提交于 2019-12-19 00:58:13
问题 I want to move the caret 4 positions to the right of where my caret currently is. I'm registered for PreviewKeyDown , and calling InsertTextInRun() when the tab key is captured, like so: private void rtb_PreviewKeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Tab) { rtb.CaretPosition.InsertTextInRun(" "); e.Handled = true; } } The problem is that the caret stays in place after the call to InsertTextInRun() . It does not move to the end of the new text, which is the behavior I want.
