这是一个普遍的如何做的DataBind工作的问题...

This is a general how does DataBind work questions...

我有一个简单的页面绑定（在ASPX code）一个GridView一个ObjectDataSource。

I have a simple page with a GridView that is bound (in the aspx code) to an ObjectDataSource.

我可以看看在调用该ObjectDataSource看到，它被称为初始负载和每一个岗位后面的select（）函数。我有一些逻辑发生在后背上，这将影响到GridView的数据，我想在后调用GridView.DataBind（）后来回来后，我已经做了一些改动。

I can look in the Select() function called by the ObjectDataSource to see that it is called on the initial load and on every post back. I have some logic that happens on post backs that will affect the GridView's data, and I want to call GridView.DataBind() later on in the post back, after I've made some changes.

有没有一种方法，以prevent自动重新绑定是发生在每个帖子后面？这是否意味着我不能使用一个ObjectDataSource这个控制？

Is there a way to prevent the automatic rebinding that happens on each post back? Does this mean I can't use an ObjectDataSource for this control?

推荐答案

你的，你要寻找的细粒度控制是不可能的，需要背后的code正确。 ASP.NET的数据源对象都不过是一个痛苦的一**。你会发现，当你使用它们，你会得到的情况是这样一次又一次此起彼伏。

You're correct in that the fine grained control you're looking for is not possible and requires the code behind. ASP.NET's data source objects are nothing but a pain in the a**. You'll find that as you use them you'll get situations like this cropping up again and again.

我已经采取做背后的code中所有的数据访问，并没有回头。

I've taken to doing all data access in the code behind and haven't looked back.
