Sir,

This is code for Search Query on multiple criteria filled by user. I am firing this query and storing result in datatable and storing that datatable in session and retreving this session on another page to display search result in listview.

My problem is that, I want to count the number of records return by this query and display them on search Result page on top for
eg: 25 Records found or if no record found display no record found..

SqlConnection con = new SqlConnection(str);
            string strQ = ("select s.Property_ID,s.Property_For,s.Property_Type,s.Property_Name,C.City_Name,L.Locality_Name,s.Price,s.Bedroom,s.Area,s.ImageName,s.ImagePath From tbl_Post_Property as s inner join tbl_City as C on C.City_Id=s.City_id inner join tbl_Locality as L on L.Locality_Id=s.Locality_Id where Property_For='"+ rbtnsearch.SelectedItem.Text +"' and s.Property_type='" + ddlpropertytype.SelectedItem.Text + "' and C.City_Id=" + ddlcity.SelectedValue + " and L.Locality_Id=" + ddllocality.SelectedValue + " and s.price between " + ddlminprice.SelectedValue + " and " + ddlmaxprice.SelectedValue + "");
            con.Open();
            SqlDataAdapter da = new SqlDataAdapter(strQ, con);
            DataTable dt = new DataTable();
            da.Fill(dt);
            Session["Search"] = dt;
            con.Close();
            Response.Redirect("SearchResult.aspx", false);

Searchresult Page

DataTable dt = new DataTable();
        dt = Session["Search"] as DataTable;         
        listview1.DataSource = dt;
        listview1.DataBind();
