If you refresh the pagelast operation performed again which is adding a record to the db in this case. You have to check with the db for the existence of the record before inserting it to avoid this. Secondly If you need your Gridview to be updated with last entered value you need to re-bind the Gridview after entering the record. Remove the databinding code from Page_Init method and create a new method with same code say BindGrid() on Page_Load Also add BindGrid(); as the last line of Button1_Click() method
