上面是dataGrid里的列，id列是隐藏的，所属区和名称是可以修改的列，现在修改完后点击“更新”按钮，获得的textBox值仍然是修改前所绑定的值。UpdateCommand()事件如下：
Private Sub dbGridfwt_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dbGridfwt.UpdateCommand
Dim s_id As String
Dim strSql, sName, sDistrict As String
Dim resultID As Integer
s_id = CType(e.Item.Cells(0).Controls(1), Label).Text
sDistrict = CType(e.Item.Cells(1).Controls(1), TextBox).Text
sName = CType(e.Item.Cells(2).Controls(1), TextBox).Text
If Trim(sDistrict) = "" Or Trim(sName) = "" Then
Exit Sub
End If
………………
dbGridfwt.EditItemIndex = -1
dbGridfwt.DataBind()
End Sub
如何才能获得输入的新值呢？？

页面postback的时候，grid里面的数据是不会丢失的
