Gridview - Issue with selectedindexchanged

[graphicsxp]

Hi,
I can't do the following:
1. detect click on a row of the gridview
2. set the EditIndex to the index of the selected row

Basically I have a checkbox column in the gridview (the only editable
column) and I'd like the row to be updated as soon as the checkbox is
ticked/unticked. Is that possible ?

Thanks
