Thanks for your response. The Virtualmode for the DataGridView appears
to be what I'm looking for, but in the wrong control.
I'm trying to create a hexviewer control. So, it would need to read
from really big files, convert the data to hex and display it in a
(TextBox) control. It would only have to show a very small portion of
the file at a time.
The best approach I have so far is to create a usercontrol composed of
a TextBox control and HScrollBar and VScrollBar controls.
