Pass ASP.Net GridView from one page to another page

Question

I want to pass all the gridview value into another page I have one gridview in PatientDetails.aspx page and one button as below

Answer 1

I found some solution:

In Source aspx after grid databind:

Session["gridtoexcel"] =  yourgrid;

In destination aspx

 var grid = ((GridView)Session["gridtoexcel"]);

            gridToExcel.Columns.Clear();
            foreach (DataControlField col in grid.Columns)
                  gridToExcel.Columns.Add(col);
            
            gridToExcel.DataSource = grid.DataSource;
            gridToExcel.DataBind();

this way i can 'clone' exact grid to another page. if you need some css style don't forget of add them in destination page

PS: gridToExcel is your destination grid
