Hi For Each control in Web page you can find TabIndex in the properties of each control and give them the order u want.

1- Session You can use Session["name"]= variable; In the other page put the session in lable or text. Label1.Text=Session["user"].ToString(); 2- QueryString SqlCommand cmd=new SqlCommand("select id from Table where id="+dgi.Cells[12].Text,sqlConnection1);
