在C ++ Builder中更新TDBGrid

Question

Embarcadero's documentation on a lot of the DB components is incomplete and asks that users update it. As a result I can't figure out how to get my DBGrid to update with a new SQL statement.

I have it call my SQL Statement just fine to begin with, however when I change the SQL statement and call the same update statement it still displays the original Grid.

I am using a TDataSource object to connect to my TADOQuery in order to fill my DBTable . When I update my TADOQuery and have it rerun the query, then call the Update Function on my DBGrid , I see no difference. Is there something extra I need to be doing with the TDataSource ?

Edit : I copied the TDataSource , deleted the original, closed and opened Builder and it worked fine.

Answer 1

复制TDataSource，删除原始的，关闭并打开的Builder，它工作正常。
