but want each row in gridview, want create new column called "click" contains button each row.

 //refetch data   datacolumn dc = new datacolumn("click", typeof(buttonfield));  _datatable.columns.add(dc);     buttonfield _buttonfield = new buttonfield();  _buttonfield.buttontype = buttontype.button;  _buttonfield.text = "testing";   _datatable.rows[0].setfield("click", _buttonfield);  //update gridview  gridview1.datasource = _datatable;  gridview1.databind();
