Scrolling a RichTextBox

[John Slater]

I have a touch screen application which I would like to use UP/Down buttons to scroll a RichTextBox. I''m unclear on how to do the scrolling.

Thanks

Hi,

See if some code like this helps for your down button, then you may try similar logic for the up button.

int newline = this.richTextBox1.Text.IndexOf("", this.richTextBox1.SelectionStart);
this.richTextBox1.Focus();
if(newline < 0)
this.richTextBox1.SelectionStart = this.richTextBox1.Text.Length;
else
this.richTextBox1.SelectionStart = newline+1;

Regards,
Stanley
