Scroll of a texbox always on bottom

Question

There is a way to keep the scroll on bottom for a multi line textbox?

Something like in the vb6

txtfoo.selstart=len(txtfoo.text)

I'm trying with txtfoo.selectionstart=txtfoo.text.length without success.

Regards.

you have two solutions (yours and @monoxide's) that both seem to do what you want. I think you should accept one of them. — Hamish Smith, Oct 05 '08 at 04:06
Except that you can't accept your own solution *shrugs* meh, I don't mind. — Matthew Scharley, Oct 05 '08 at 11:25

Ok, I found that the solution was to use

txtfoo.AppendText

instead of

 txtfoo.text+="something"

The other solution is to use:

txtfoo.Text += "something";
txtfoo.SelectionStart = txtfoo.Text.Length;
txtfoo.ScrollToCaret();

Interesting question. I'm guessing that you are trying to select the text via form load? I can't get it working on form load, but I can on form click. Wierd. :)

Public Class Form1

    Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
        ScrollTextbox()
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ScrollTextbox()
    End Sub

    Private Sub ScrollTextbox()
        TextBox1.SelectionStart = TextBox1.TextLength
        TextBox1.ScrollToCaret()
    End Sub

End Class

If it is completely necessary, you could use a timer.

I'd guess it has something to do with the form not being properly initialised yet in the load handler. Try putting a call to this.Show() first, should clear up any issues. — Matthew Scharley, Oct 08 '08 at 10:21
