Automatic scroll of RichTextBox

[Guest]

Hi,

Is it possible to scroll a RichTextBox programmatically to a given text
selection in it, such that the selected text becomes viewable.

regards.
Jesper.

Hi Jesper,

For this, first specify the "SelectedText" of the richtextbox control and
then call the ScrollToCaret method. Here's an example:

'Handles the Enter key being pressed while TextBox1 has focus.
Private Sub TextBox1_KeyDown(ByVal sender As Object, _
ByVal e As KeyEventArgs) Handles TextBox1.KeyDown
TextBox1.HideSelection = False
If e.KeyCode = Keys.Enter Then
e.Handled = True

' Copy the text from TextBox1 to RichTextBox1, add a CRLF after
' the copied text, and keep the caret in view.
RichTextBox1.SelectedText = TextBox1.Text + _
Microsoft.VisualBasic.vbCrLf
RichTextBox1.ScrollToCaret()
End If
End Sub

Hope this helps.
Thanks
