help me in locating control data

 Hi,
     i'm creating an asp table at the server side. and the table contains Text Boxes. When we enter data in a text box, TextBoxt_OnTextChanged Event will be fired. All Text Boxes contains event handlers.  In, OnTextChanged event, how can i determine the textbox being modified.. hope i'm clear in explaining.
kindly help me in fixing this issue,
Thanks & Regards,
