If you want to store something in session just do so.

(vb.net)

Session("key") = "the value to be stored in session at the key provided"

(c#)

Session["key"] = "the value to be stored in session at the key provided";

When you need to access later do the following:
(vb.net)

Dim valueRetrievedFromSession As String = Session("key")

(c#)

String valueRetrievedFromSession = Session["key"];

I just told you what to do.
I'm not sure I could explain it any more clearly....hmm maybe I can:

In the method that you have implemented that handles the button click event......store the information into session.

Then in the next page retrieve the information from session.

It would be a lot easier to help you if you posted what you have tried so far along with an explanation of what is not working so that we can go from there.

i have many button which is dynamically created .i don't know the value of these button.at run time these button will create according to condition.then from there button i want to select one button and i want to use the text value of selected button on next pages or on other pages.so i want to pass the value(text value of selected button) in session.so plz tell me how can i do this.plz.plz

Simply store the .Text property of the button in session.

Sessio["buttonText"] = theButtonInstance.Text

In your case you have a bunch of button texts that you want to store...you can store an array or list of strings in session too:

List<string> buttonTexts = new List<string>();
 
for (int i = 0; i < 3; i++)
{
  lbn[i] = new LinkButton();
  lbn[i].ID = "lbn" + i;
  lbn[i].Text = "</br>"+"lbn" + i;
  buttonTexts.Add("</br>"+"lbn" + i);
//  ...
}
Session["buttonTexts"] = buttonTexts;

You should probably check out this article on How to use dynamic controls in ASP.NET. I think you're going to run into problems eventually if you keep using your current solution.
