如何为同时选中的几个dbgrid的onkeyDown写入事件代码

怎么为同时选中的几个dbgrid的onkeyDown写入事件代码？
我试过属性可以同时赋值，但是事件似乎要分开写，很麻烦

[解决办法]
举个例子:
假设DBGrid1,DBGrid2,DBGrid3的OnKeyDown事件都指向DBGrid1KeyDown,那么:

C/C++ code

void __fastcall TForm1::DBGrid1KeyDown(TObject *Sender, WORD &Key,      TShiftState Shift){    if (Sender == DBGrid1)        Caption = "DBGrid1";    else if (Sender == DBGrid2)        Caption = "DBGrid2";    else if (Sender == DBGrid3)        Caption = "DBGrid3";}
