simple radiobuttonlist problem

Hi,

I've a repeater which has a radiobuttonluist inside its itemtemplate, now what i want is, when i call

radiobuttonlist.datasource="dictionary";

radiobuttonlist.databind();

i want to control each item's binding , i mean , which is that event where i can control the individual radiobutton by using the datasource at that time (something like e.Item.DataItem as in gridview). hope i made it clear.
