using image button & accessing info from datagrid

<i><b>Originally posted by : Jenny (jreyes@gisimplement.com)</b></i><br />Hi!<br /><br />1. I want to use an image button in my datagrid, instead of link button. <br /> I want the program to know the exact record or row which the user click using the image button. <br /> Are these possible?<br /><br /><br />2. Is it possible to retrieve cell information coming from an ItemTemplate Column which uses a function to retrieve cell data coming from a different table(unbound data)?<br /><br />Thanks.<br /><br />Best regards,<br /><br />Jenny <br />
