    I've two page aspx: first page is search.aspx, second page is reasult.aspx

    into page search.aspx i write this code:



    "reasult.aspx?_str1=" & Txtsearch1.Text & "&_str2=" & Txtsearch2.Text)

    and then pass the values to the second page result.aspx....Into first page there's a ajaxloadingpanel that appears when I send the data, but the loading is still.

    Perhaps because the page has result.aspx in load_page loading data from the database? And so it stops loading.

    this code in second page:


    Imports System
    Imports System.Data
    Imports System.Web
    Imports System.Data.SqlClient
    Imports Telerik.Web.UI
    Imports System.IO
      Private Loadsearch As New GestoreUtente     
      Dim list As List(Of PropertyUtente) = Loadsearch.Search(_str1, _str2)
            RadListView1.DataSource = list
    Public Class GestoreUtente
        Public Function Search(ByVal _Str1 As String, ByVal _Str2 As String) As List(Of PropertyUtente)
            Dim lista As New List(Of PropertyUtente)
                Dim conString = ConfigurationManager.ConnectionStrings("TrycontactString")
                Dim strConnString As String = conString.ConnectionString
                Using db As New SqlConnection(strConnString)
                    Using sqlcmd As New SqlCommand("Sp_searching_like", db)
                        sqlcmd.CommandType = CommandType.StoredProcedure
                        sqlcmd.Parameters.AddWithValue("@Search", SqlDbType.VarChar).Value = _Str1
                        sqlcmd.Parameters.AddWithValue("@Searchluogo", SqlDbType.VarChar).Value = _Str2
                        Using sqldr As SqlDataReader = sqlcmd.ExecuteReader
                            While sqldr.Read
                                lista.Add(New PropertyUtente With {.idutente = sqldr.GetSqlInt32(0).Value, _
                                                                    .utente = sqldr.GetSqlString(1).Value, _
                                                                    .Desccategoria = sqldr.GetSqlString(2).Value, _
                                                                    .Desccomune = sqldr.GetSqlString(3).Value, _
                                                                    .Telefono = sqldr.GetSqlString(4).Value, _
                                                                    .Cellulare = sqldr.GetSqlString(5).Value, _
                                                                    .Imageprofile = sqldr.GetSqlString(6).Value, _
                                                                    .Email = sqldr.GetSqlString(7).Value})
                            End While
                        End Using
                    End Using
                End Using
            Catch ex As SqlException
                Exit Try
            Catch ex As Exception
                Exit Try
            End Try
            Return lista
        End Function
    End Class

    Hello Fabio,

    Note that when performing redirect to another page there is no request to the server and respectively there is no ajax ResponseEnd event to fire. Therefore the RadAjaxLoadingPanel could not indicates end of the request to hide on. You could handle an appropriate client event which fires before redirecting the page and manually hide the loading panel as shown here:

    Kind regards,
