看来搜索后两天，我已经找到了一个不错的解决方案，更快，更容易比其他一些理解！;看起来，作为其他答案的状态，这是因为page_load，但是在这种情况下，init不是必需的，您只需重新创建所有控件，然后再执行其他任何操作。
该解决方案的关键在于：
protected void RecreatePreviousState()
{
if (this.IsPostBack)
{
//code to recreate
}
}
凡在上面的代码中的注释是，在这里你调用创建所有控件，就像在我的例子是主要功能：
ConnectToSql(Searchbox.Value) 下面将是与此页面相关的所有代码，供将来参考此问题的任何人。

在那里你调用方法table_Builder – SMK
使用[数据绑定的WebControl喜欢的GridView，中继器或ListView] （http://msdn.microsoft.com/en-us/library/ms228214.aspx）。 [Here]（http://www.beansoftware.com/ASP.NET-Tutorials/Repeater-DataList-ListView-GridView.aspx）的概述。这让生活变得更轻松。 –
