You could try something like this. Assuming that the textboxes are named sequentially as txtName1, txtName2, txtBook1, txtBook2 etc. and the field names are "name", "book" etc.

        int count = 0;
        Dictionary<string, string> TextBoxValues = new Dictionary<string,string>();
        while(dr.Read())
        {
            count++;
            TextBoxValues.Add("txtName" + count, dr["name"].ToString());
            TextBoxValues.Add("txtBook" + count, dr["book"].ToString());
        }

        txtName1.Text = TextBoxValues[txtName1.ID];
        txtName2.Text = TextBoxValues[txtName2.ID];

        txtBook1.Text = TextBoxValues[txtBook1.ID];
        txtBook2.Text = TextBoxValues[txtBook2.ID];
