column:"+item.column);
value[i] = data.getValue(item.row,item.column);
alert("You selected the value:"+value[i]);
} else if (item.row != null) {
message += '{row:' + item.row + '}';

}
}
if (message == '') {
message = 'nothing';
}
alert('You selected ' + message);
}
This is the code. The getValue function seems to return the data item,
but when i do the above i am unable to see anything returned.
Please help.
Thanks,
Madhan
