Hi,
You will need to handle the Grid's ClientSideOnItemSelected first and then trigger a post back using whatever way you'd like, typically with Grid.raiseItemCommandEvent. It will be something like this:
Code: HTML/ASPX
<eo:Grid ClientSideOnItemSelected="client_select_handler" ...>
....
</eo:Grid>
Code: JavaScript
function client_select_handler(grid)
{
//Get the selected row index
var index = grid.getSelectedItem().getIndex();
//Raises server side ItemCommand event
grid.raiseItemCommandEvent(index, "anything");
}
You would then handle the Grid's ItemCommand event on the server side.
Thanks!
