第一:
在你刷新前保存所在位置的行号
procedure XXXClass.LockPositionEx;begin DisableControls;
FHistoryRecNo := 0; FHistoryIndexName := EmptyStr; if Active then begin if IndexName <> EmptyStr then FHistoryIndexName := IndexName; IndexName := EmptyStr;
if not IsEmpty then if (State in [dsEdit,dsInsert]) then FHistoryRecNo := -1 else FHistoryRecNo := RecNo; end;end;
第二刷新后定位到新行号
procedure XXXClass.UnlockPositionEx;begin if Active then begin if not IsEmpty then if FHistoryRecNo < 0 then//处理编辑状态,直接跳至最后一条记录 Last else if FHistoryRecNo = 0 then First else if FHistoryRecNo > 0 then// begin if RecordCount >= FHistoryRecNo then RecNo := FHistoryRecNo else if RecordCount > 0 then Last; end; if FHistoryIndexName <> EmptyStr then begin IndexName := FHistoryIndexName; FHistoryIndexName := EmptyStr; end; end;
EnableControls;end;
