Decide Destination Page URL from Database based on code using ASP.Net

HI

I have 3 page   index.aspx  and store.aspx and Electric.aspx

In index.aspx I have TB and button and this is my user’s table

When user type their behcode in TB it go to store.aspx and fill this page with user’s information

This is my code I use query string

 protected void ImageButton3_Click(object sender, ImageClickEventArgs e)
    {
    
        Response.Redirect(store.aspx?behcode=" + Server.UrlEncode(txtNumeric.Text));
     


    }

and store.aspx code

  protected void Page_Load(object sender, EventArgs e)
    {
        string data = Server.UrlDecode(Request.QueryString["behcode"]);
         
            SqlCommand _cmd = new SqlCommand("storeproduct" ,_cn);
            _cmd.CommandType = CommandType.StoredProcedure;
            _cmd.Parameters.AddWithValue("@BehCode", data);
            _cn.Open();
            SqlDataReader _dr = _cmd.ExecuteReader();
            if(_dr.HasRows)
            {
                DataList1.DataSource = _dr;
                DataList1.DataBind();
                
                
             
            }

Now I want when user enter their behcode in TB when they click on button it checked T_name column from user’s table if T_name was Store it go to Store.aspx and if T_name was Electric it go to Electric.aspx and fill this page with users information with behcode that they enter in TB                thanks alot
