What you should do is populate the text box only if the page has not been postback yet:

namespace WebApplication4 
{ 
  public partial class WebForm17 : System.Web.UI.Page 
  { 
     DATAACCESS aaa = new DATAACCESS(); 
     string  Dname = "Finding"; 

     protected void Page_Load(object sender, EventArgs e) 
     {  
          aaa = new DATAACCESS(); 

          if(!IsPostBack)
          {
              TextBox2.Text= aaa.GetDoctext(Dname, 90); 
          }
     } 

     protected void Button5_Click(object sender, EventArgs e) 
     { 

         string textboxvalue = TextBox2.Text;
         aaa.savetext(textboxvalue, Dname, 90); 
     } 
  } 
}
