请高手指教：

哥哥，你说的清楚些嘛
我也知道在click里设置，
就是不知道用什么代码实现啊
拜托各位大虾指教的详细点哦

Command1代码：

thisform.pageframe1.page1.commandgroup1.command1.enabled=.f.

thisform.pageframe1.page1.commandgroup1.command2.enabled=.f.

thisform.pageframe1.page1.commandgroup1.command3.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command4.enabled=.t.

thisform.pageframe1.page1.grid1.setfocus

thisform.pageframe1.page1.refresh

go top

Command2代码：

thisform.pageframe1.page1.grid1.setfocus

thisform.pageframe1.page1.refresh

skip -1

if bof()

messagebox("已是第一条记录！",48,"提示")

thisform.pageframe1.page1.commandgroup1.command1.enabled=.f.

thisform.pageframe1.page1.commandgroup1.command2.enabled=.f.

else

thisform.pageframe1.page1.commandgroup1.command1.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command2.enabled=.t.

endif

thisform.pageframe1.page1.commandgroup1.command3.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command4.enabled=.t.

Command3代码：

thisform.pageframe1.page1.grid1.setfocus

thisform.pageframe1.page1.grid1.refresh

skip

if eof()

messagebox("已是最后一条记录！",48,"提示")

thisform.pageframe1.page1.commandgroup1.command3.enabled=.f.

thisform.pageframe1.page1.commandgroup1.command4.enabled=.f.

else

thisform.pageframe1.page1.commandgroup1.command3.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command4.enabled=.t.

endif

thisform.pageframe1.page1.commandgroup1.command1.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command2.enabled=.t.

Command4代码：

thisform.pageframe1.page1.commandgroup1.command1.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command2.enabled=.t.

thisform.pageframe1.page1.commandgroup1.command3.enabled=.f.

thisform.pageframe1.page1.commandgroup1.command4.enabled=.f.

thisform.pageframe1.page1.grid1.setfocus

thisform.pageframe1.page1.grid1.refresh

go bottom

另外还需要在grid1的arftrowcolchange中写入
this.setall('dynamicbackcolor','iif(this.activerow< >recno(),rgb(238,251,255),rgb(153,204,255)','column')

在表格控件的每列的text1控件的GotFocus事件中添加以下代码：
this.backcolor=rgb(153,204,255)
