Add and remove RTF-text in a RichTextBox at runtime?

[M O J O]

Hi,

How do I add and remove PART of the RTF-text in a RichTextBox?

If I use...

MyRichTextBox.Text = "New text" & MyRichTextBox.Text

.... then all my RTF (higlight, bold, underline and so on) is removed.


Thanks!

Select the text by calling the overloaded version of the control's
'Select' method and the set its 'SelectedText' property to "".

Hi Mojo,

Thanks for posting in the community. My name is Peter, and I will be
assisting you on this issue.

First of all, I would like to confirm my understanding of your issue.
From your description, I understand that you wants to add or remove part of
the RTF-Text in a RichTextBox.
Have I fully understood you? If there is anything I misunderstood, please
feel free to let me know.

I agree with Herfried's suggestion.
For RTF-Text you may try the SelectedRtf as below.

Dim o As New RichTextBox
o.Rtf = "{\rtf1\ansi This is in \b bold\b0.}"
Me.Controls.Add(o)
'The line will insert the rtf where the curser is.
o.SelectedRtf = "{\rtf1\ansi This is in \b bold\b0.}"
'This will remove part of the RTF-Text.
o.Select(5,7)
o.SelectedRtf = ""
