        在VB.NET 2003的DataGrid中，通过使用编辑列可以在页面中实现一种无刷新效果，其实现代码如下：

        在DataGrid的EditCommand事件中代码如下：
        Private Sub DataGrid_EditCommand(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid.EditCommand
            DataGrid.EditItemIndex = e.Item.ItemIndex
            '数据绑定
            BindData()
        End Sub

        在DataGrid的UpdateCommand事件中代码如下：
        Private Sub DataGrid_UpdateCommand(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid.UpdateCommand
            '数据更新
            Update()
            DataGrid.EditItemIndex = -1
            '数据绑定
            BindData()
        End Sub

        在DataGrid的CancelCommand事件中代码如下：
        Private Sub DataGrid_CancelCommand(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid.CancelCommand
            DataGrid.EditItemIndex =  -1
            '数据绑定
            BindData()
        End Sub
