The second method:

<form id= "Form1" runat= "Server" action= "receive.aspx" method=post>
<div>
<asp:button id= "Button1" runat= "Server" onclick= "Button1_Click" text= "button"/>
<asp:textbox id= "username" runat= "server" ></asp:TextBox>
</div>
</form>

The third method:

{
session["username"] = "Honge";
Request.redirect ("default2.aspx");
}

The Fourth method:

}
}

If you can also use this in asp.net 2.0:

Copy Code code as follows:

PreviousPage d = Context.Handler as previouspage;
if (d!= null)
{
Response.Write (D.name) so that the parameter values can be obtained.
}

You can also use this:
Send.aspx:

Copy Code code as follows:

<asp:button id= "btnsubmit" runat= "Server" postbackurl= "~/reveive.aspx" text= "Submit"/>

Receive.aspx:

Copy Code code as follows:

<%@ previouspagetype virtualpath= "~/default.aspx"%>
String name = Previouspage.name, so you can get parameter values.

<a href= "Article.aspx? id=<% #DataBinder. Eval (Container.DataItem, "article_id")%> "target=" _blank ">//" go to the link page and Id,id as a field in the database;
