Do you mean a listbox, or a continues form, or a 3rd party data grid
control?

SelLeft was never application to  your question in any context....

Remember, a listbox, or a continues form looks very similar. Here is some
screen shots of what I mean:

Also, it depends in terms of what context. If you have data displayed in a
grid like format (a continues form), then you can pick up the current
control via code such as:

screen.ActiveControl.Name

The above would return the current controls name. However, if you click a
button, then the active control is now the button you clicked (and the focus
has moved/changed. So, what context you trying to do under is also very
important.

opps, those data screen examples of how a listbox, or contineus form looks
simular is here:
