but one thing, surely if i dont know how many textboxes there are then i cant do the following

int Count=1;
 foreach (DataRow row in dataSetselectactivities.Tables[0].Rows)
        {
            string textboxValue= ((TextBox)this.Page.FindControl("txt_" + Count.ToString())).Text;  
           Count+=1;
           
           // Do something here
        }

Now, 'A' can access the page by giving other User's Id after entering into this page. I want to make that address bar as read only after loading this page.

if(Session["id"] != NULL && Session["id"].ToString() != Request.QueryString["id"])
{
   Response.Redirect("NotAuthorized.aspx");
