don't want Datagrid to select row on click

[Lobo]

Hi,
I have a datagrid with enabled=true and readonly=false. Enabled must be true because otherwise I dont get the Mouseevents.
The problem is that it should not be possible to select a row. I can do this by setting currentrowindex = -1, but by the next click I get an indey out of range.

How can I just disable the selection of rows?

thank you!

Edit: grid.unselect(grid.currentrowindex) somehow does nothing at all.
