What can I do when I retrive the event object from dbclick?

obj.setEvent("ondblclick", function(event){
alert(event);
});

Here,what's the properties of the event object?How can I get some selected row/cell information from this event object?

This is just standard browser event object, it does not containt any information about the grid. Use getSelectedRows/getSelectedColumns methods to get the current selection.

Ok,Thank you very much.

It's a nice information for me. :)
