Dynamically turning on and off DataGrid Scroll Bar

[Pete]

The selectionChanged message sent to the datagrid has two parameters: the
index of the line just clicked and the index of the line that was selected
before the click.  I'm not sure what you mean by "deselect" but if you mean
go back to the previously highlighted line, you can use the second
parameter to do that

If you mean you just don't want any line to be selected, you can set the
dghilitedline to zero (or maybe it's empty, can't remember which).
