DataGrid RowDeleting event problem

Question

Hi all, I am working with asp.net 2.0 and i am using a datagrid in which i use an button to delete an an item and it works perfectly if i dont call a confirmation javascript. i bind the javascript function in rawdatabound event to that button. when i use this javascript confirmation, the RowDeleting event doesnt get fired. but page load occures. Any idea friends? Thanks in advance. Ali
