我仔细研究过你的代码，但有些功能没有实现，我应该在哪里创建hyperlink呢？我是按照你讲的创建linkbutton方法创建的啊。

the reason is that you are creating the hyperlink controls before the Page index is changed!

I posted the code for a PageControl in your post before, if you carefully studied it, you will see how to do it

属性只有 nStartcount用到了viewstate,不知有无影响？
private DataTable dtbname;

[Bindable(true),
Category("data"),
DefaultValue("")]
public DataTable Dtbname
{
get
{
return dtbname;
}

set
{
dtbname = value;
}
}

//每页记录数
private int pageSize;
[Bindable(true),
Category("data"),
DefaultValue("")]

public int PageSize
{
get
{
return pageSize;

}

set
{
pageSize = value;

}
}
//开始记录

public int nStartcount
{
get
{
if (ViewState["nStartcount"] == null)
return 0;
return (int)ViewState["nStartcount"];
}
set
{
ViewState["nStartcount"] = value;
}
}
