Use the SelectRowByKey(Object) and UnselectRowByKey methods to select and deselect the row specified by the key value.

    KeyFieldName="ProductID" OnCustomCallback="gridview_CustomCallback">
        <dx:GridViewCommandColumn ShowSelectCheckbox="true" VisibleIndex="0" />

    var grid = sender as ASPxGridView;
    var rowKey = 6;
    if(grid.Selection.IsRowSelectedByKey(rowKey)) {
