delphi7 dbgrid 数据不要超过100万条

delphi7 ado zeos 连接sqlserver2008 ，adoquery+datasource+dbgrid。
记录数超过100万程序容易出现卡死，或者提示对象被打开错误，

it has a GridMode which lets you load a initial set of rows
and when scrolling it fetches the next set

Try the Virtual Treeview component, you can use it as a list (grid) as well.

You could use a background thread to load the database records into user defined records.

good luck
