//设置窗体的KeyPreview为True
procedure TForm1.FormKeyPress(Sender: Tobject; var Key: Char);
begin
if Key = #13 then
if not (ActiveControl is TDBGrid) then
begin
Key := #0;
Perform(WM_NEXTDLGCTL, 0, 0);
end
else
if (ActiveControl is TDBGrid) then
with TDBGrid(ActiveControl) do
if selectedindex $#@60; (fieldcount -1) then
selectedindex := selectedindex +1
else
selectedindex := 0;
end;
2．删除记录前显示汉语的提示对话框
//设置DbNavigator的ConfirmDelete属性为False
//在数据集控件的BeforeDelete事件中编写如下代码：
if Application.MessageBox("确定要删除当前记录吗？", "删除 记录", Mb_YesNo + Mb_IconWarning) =
Id_No then
Abort; //利用哑异常退出删除事件
