Could not find file on FileUploaded

[Avery]

Hello.  I have the following set of code which to me seems like it should work but I am unable to saveas the file on FileUploaded. I get the error message: Sys.WebForms.PageRequestManagerServerErrorException: Could not find file 'C:\directory path where temp files should be\rje044e5.4bx'

For the life of me I can't figure out what I'm doing wrong here.  Any help?  Thank you very much!

Hello Avery,

We had similar issue in one of the previous versions of the controls, it's described here - could you please check whether this solves the problem? Let us know the result.

Hi Yana.  That did not solve my problem.  Same error. I am using RadControls Version: v.2010.3.1109.40.

Hello Avery,

Could you please try to isolate this issue in a simpler page and send it to us? You should open a support ticket and attach it there.

All the best,

I also have this problem, sporadically. All my test files are tiny PNGs.

Version: 2010.3.1317.35

I have two buttons, Save and Send, that need to process the uploaded files:

 

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

 

 

<script type="text/javascript">

 

 

var $ = $telerik.$;

 

 

 

var uploadsInProgress = 0;

 

 

 

function onFileSelected(sender, args) {

 

 

 

if (!uploadsInProgress) {

 

 

$(

"#btnSend").attr("disabled", "disabled");

 

 

$(

"#btnSave").attr("disabled", "disabled");

 

 

}

 

uploadsInProgress++;

 

}

 

 

function onFileUploaded(sender, args) {

 

 

decrementUploadsInProgress();

 

}

 

 

function onUploadFailed(sender, args) {

 

 

decrementUploadsInProgress();

 

}

 

 

function decrementUploadsInProgress() {

 

 

uploadsInProgress--;

 

 

if (!uploadsInProgress){

 

 

$(

"#btnSend").removeAttr("disabled");

 

 

$(

"#btnSave").removeAttr("disabled");

 

 

}

 

}

 

 

 

 

</script>

 

 

</telerik:RadScriptBlock>

 

 

 

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default"></telerik:RadAjaxLoadingPanel>

 

 

 

<input type="hidden" id="UploadedFilesJson" runat="server" />

 

 

 

 

 

<telerik:RadAsyncUpload runat="server" ID="AsyncUpload1" Skin="Office2007" OnClientFileUploadFailed="onUploadFailed"

 

 

ReadOnlyFileInputs="true" OnClientFileSelected="onFileSelected" OnClientFileUploaded="onFileUploaded">

 

 

 

</telerik:RadAsyncUpload>

 

In either btn routine, I call this subroutine:

 

Private Sub Upload_GetFiles()

 

 

 

Try ' For Telerik code, http://demos.telerik.com/aspnet-ajax/upload/examples/async/webmail/defaultvb.aspx?product=asyncupload

 

 

   
    For Each file As UploadedFile In AsyncUpload1.UploadedFiles

 

 

 

        Dim uploadedFileInfo As New UploadedFileInfo(file)

 

 

        Session(

"Dropbox_AttachmentCount") += 1 ' One more file came in

 

 

        Dim sFileName As String = Session.SessionID.ToString & "_" & Session("Dropbox_AttachmentCount").ToString '  Temp Name
        sFileName &= uploadedFileInfo.FileName.Substring(uploadedFileInfo.FileName.LastIndexOf("."), 4) ' Add the suffix
        file.SaveAs(Path.Combine(Server.MapPath("~/attachments/temp"), sFileName))

 

 

 

    Next

 

 

Catch ex As Exception

 

 

    SecureDropBox.ShowError(

Me.Page, ex.Message)

 

 

 

End Try

 

 

End Sub

 

The "file.SaveAs" is where I get an exception, sometimes. I haven't isolated the frequency/symptoms yet but it seems like about every fourth or fifth time that I do a SAVE btn click. Every attempt has one, two or three small PNG files. Running on my desktop in development (VS2008) so timing should not be an issue.

I can submit a support ticket with my entire solution, if that helps.

Thanks in advance.

Hi Martin,

The fix has already been fixed in a later version. Is it possible to upgrade?
