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();
Session["Data"]=obj1;
And to get that object in Page2, use code as shown below:
if(Session["Data"]!=null)
{
classA obj= (classA)Session["Data"];
}
