asp.net passing object between two pages..

Its Simple Dude, Use Session Variable to Pass Data Between Multiple Pages, suppose you need to pass an object of Class classA from page Page1 to page Page2; then store the object in session in Page1 as shown below:

  classA obj1=new classA();  //create object of classA
//code to set values in obj1
  Session["Data"]=obj1;  //store object in session variable

And to get that object in Page2, use code as shown below:
if(Session["Data"]!=null)
{
// Get value from Session  variable and cast it to its corresponding type
   classA obj= (classA)Session["Data"]; 
}
