just deselect first row after you've filled grid. default first row selected when fill it, possible have no rows @ selected.

datatable dtb = new datatable("d"); dtb.columns.add("c1"); dtb.rows.add("a"); dtb.rows.add("b"); dtb.rows.add("c"); dtb.rows.add("d"); dtb.rows.add("e"); datagridview1.datasource = dtb; datagridview1.selectionmode = datagridviewselectionmode.fullrowselect; if (datagridview1.selectedrows.count > 0) {     datagridview1.rows[0].selected = false; }
