How to programmatically change text to underlined style in RichTextBox?
-
Hi, this is a two-step process: 1. select the text that needs special handling; you can do that interactively, or programmatically; while it already is in place, or while adding. 2. choose a new font for the selected text (RichTextBox.SelectionFont Property) and use FontStyle.Underline for it. For all the details, read up on the RichTextBox and Font classes. :)

Thanks. Well there's a problem. What if my selection includes multiple fonts? RichTextBox.SelectionFont Property returns
nullin that case. How can I underline my selection without changing the original fonts?Hi, if multiple styles are selected, the selection has to be split up into homogeneous parts; select and underline each part in turn; then restore the original selection. :)

Thank you. :-D Your suggestion worked. I splitted my multi-font-selection into several homogeneous parts, selected each part and underlined them one after another. Finally I restored the original selection. However, as I try out the program, it flickers.

sure, all Controls basically have that problem, and the more data they hold and the more operations you perform on them, the more it shows. Here are some suggestions to reduce the flickering, you pick and choose: - optimize your code; tha faster it runs the less you will notice it; - try using SuspendLayout() and ResumeLayout(); I'm not sure how well it helps with an RTB; - difficult: get the Rtf property, operate on it (that's string operations now, not very elegant), and when done, store it again - alternative: have a second RTB, not visible, copy the Rtf from the first to the second, operate on the second RTB, then copy back the Rtf. This should work nicely. :)
