You can use session/query string to pass values from one page to another. query string Response.Redirect("Home.aspx?value="'+ddl.SelectedItem.Value+'"); on another page you can receive string temps=Request.QueryString["value"]; Session Session["TempToStore"]=ddl.SelectedItem.Value; Or In case of large data you can use XML Manipulation to write or Read. There is another way to create dataset and store it into session http://stackoverflow.com/questions/2288299/storing-and-retrieving-datatable-from-session

Try This and then use

Initialize array
Int32[,] Process = new Int32[5,5];

Int32 i = Convert.ToInt32("1");
Int32 j = Convert.ToInt32("1");
Process[i,j] = Convert.ToInt32("45");
