[Fabio Cirillo]

Hello,
i want to uplaod file with radasyncupload....and i want get name file uploaded too. Then my code is:

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server"
AllowedFileExtensions="jpg,jpeg,png,gif" Font-Names="Verdana"
ManualUpload="True" MaxFileInputsCount="1" MaxFileSize="3000000" Skin="Sunset"
Width="343px">
<Localization Select="Cerca" />
</telerik:RadAsyncUpload>

function startManualUpload() {
var upload = $find('<%=RadAsyncUpload1.ClientID%>');
upload.startUpload();
}

and start upload with code behind:

   Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
       If Not IsPostBack Then
           RadAsyncUpload1.TargetFolder = "~/Image/image_utenti/" & Session.Item("idutente")
       End If
   End Sub

Protected Sub Imgbtncarica_Click(sender As Object, e As System.Web.UI.ImageClickEventArgs) Handles Imgbtncarica.Click
       ScriptManager.RegisterStartupScript(Page, Me.GetType, "Upload", "startManualUpload();", True)
       ViewState("DirImage") = ViewState("RemoteFolder") & RadAsyncUpload1.UploadedFiles.Item(0).FileName
       update_image(Session.Item("idutente"), ViewState("DirImage"))
   End Sub

If i click on button "Imgbtncarica" the file in not uploaded, because i go to see into folder and there's not the file....Why?
