the following shows a complete example of the code-behind file associated with the web forms page sending the information. depending on whether you use visual basic or c#, make sure this sample is called firstpage.aspx.vb or firstpage.aspx.cs, respectively.
[visual basic]
imports system
public class firstpageclass :
inherits system.web.ui.page
protected first as system.web.ui.webcontrols.textbox
protected last as system.web.ui.webcontrols.textbox
protected button1 as system.web.ui.webcontrols.button
public readonly property firstname() as string
get
' first is the name of a textbox control.
return first.text
end get
end property
public readonly property lastname() as string
get
' last is the name of a textbox control.
return last.text
end get
end property
sub buttonclicked(sender as object, e as eventargs)
server.transfer("secondpage.aspx")
