I have a rich text box in my winform.
I would like to achieve the following:

When I use my mouse to select a range of text on row 1 of my rich text box, the rest of the rows will be highlighted on the same position.

For example, if I have the following text in my rich text box:


If I use my mouse to select 123 above, 567 and 890 will both be highlighted or selected.

Is it possilbe to achieve this in WinForms?
I know the RichTextBox can only select a range of text at one time and I have tried to use RTF but things got complicated.

Any idea what can I do?

Thanks in advance.
