RadUpload does not upload file

[David House]

We have placed a RadUpload control in a DotNetNuke module and selected the file. We also have an asp:button on the control set to Submit. When we press the button, the RadUpload.UploadedFiles.Count is always ZERO and the file never gets uploaded. The page is being refreshed by the submit button during the postback.

Here is the GUI code:

 

<asp:Panel ID="pnlFileUpload" runat="server">

 

Allowed File Extensions are: .jpg, .gif, .bmp, .png

 

<telerik:RadUpload id="RadUpload1" Runat="server" AllowedFileExtensions="jpg, gif, bmp, png" TargetFolder="~\Portals\0\ClientLogos" MaxFileInputsCount="1" >

 

 

</telerik:RadUpload>

 

 

<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click" />

 

 

</asp:Panel>

 

the btnUpload button is set to UseSubmitBehavior=True. What are we missing?  DotNetNuke version 5.04.02 community.

Hello David House,

Please make sure that RadUpload is not inside UpdatePanel/RadAjaxPanel or ajafixied using RadAjaxManager. RadUpload cannot upload files using AJAX calls. This is a limitation of the XmlHttpRequest component, used in all AJAX frameworks for asynchronous calls to the application. In order to upload a file your application must perform a full page postback. More information on the topic can be found here. You can also take a look at this troubleshoot article, describing a case when the uploaded files collection is empty.

In addition, information on how RadUpload can be used inside DNN can be found here.

I have the exact issue; however, mine is not inside of DNN.
Here's my code. It's not uploading.

<telerik:RadUpload ID="RadUpload1" Runat="server" Height="131px"
        MaxFileSize="204800" TargetFolder="~/TempFiles/" TargetPhysicalFolder="~/Upload/">
    </telerik:RadUpload>
    <asp:Button ID="btnUpload" runat="server" Text="Upload" />

[Chuck]

Okay, I just followed this Getting Started tutorial and it's still not uploading. Below is my code:

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">
</telerik:RadScriptManager>
<telerik:RadUpload ID="rduFile" Runat="server" MaxFileSize="204800"
    TargetFolder="~/Media" AllowedFileExtensions=".mp3"
        ControlObjectsVisibility="RemoveButtons"
        MaxFileInputsCount="1" Skin="Forest" Height="25px">
</telerik:RadUpload>
<telerik:RadProgressManager ID="RadProgressManager1" Runat="server" />
    <telerik:RadProgressArea ID="RadProgressArea1" Runat="server"
        DisplayCancelButton="True"
        ProgressIndicators="TotalProgressBar, TotalProgress, TotalProgressPercent, RequestSize, FilesCountBar, FilesCount, SelectedFilesCount, CurrentFileName, TimeElapsed, TimeEstimated, TransferSpeed"
        Skin="Forest">
    </telerik:RadProgressArea>
<asp:Button ID="btUpload" runat="server" Text="Upload" onclick="btUpload_Click" />

And here's the button click method.

protected void btUpload_Click(object sender, EventArgs e)
   {
       if (rduFile.UploadedFiles.Count > 0)
       {
           System.Threading.Thread.Sleep(3000);
       }
   }

Any other suggestion?

Hello Chuck,

If the UploadedFiles collection is empty than the uploaded file is not valid. The problem in your case is the size of the MaxFileSize property. Please note that this property defines the maximum allow file size in bytes which means that currently you could upload files which are less than 200 killobytes. You should increase this property especially of you want to upload mp3 files. Here you could find a useful only converter.

Kind regards,

Okay, that works. I thought the MaxFileSize property is set KiloByte and not Byte. Anyway, the progress bar never showed up. Any suggestion why?

[Chuck]

One other thing, how do I grab the file name of the RadUpload control and store it in my own database?

[Dimitar Terziev]

Hello,

Here is a sample code showing how to get the name of the uploaded file:

protected void Button_Click(object sender, EventArgs e)
{
    foreach (UploadedFile file in RadUpload1.UploadedFiles)
    {
        file.SaveAs(Server.MapPath("~/Uploads/" + file.GetName()));
    }
}

You could also use the GetExtension() method which will give you only the extension of the uploaded file.

Thanks for the response; however, I still not quite get what you're code is trying to do. I'm not trying to save because the RadUpload is already doing that. I'm simply getting the file name. Here is what I've done with the standard FileUpload control in Visual Studio 2010:

e.Values["fileName"] = FileUpload1.FileName;

So, the question is. How do I do the same thing with RadUpload? I do not see the "FileName" or "File.GetName" being available.

[Chuck]

One other thing is, how do I test if the RadUpload1 uploaded successfully? For example:

if(RadUpload1.Upload.Success)
{
// add the file name into the database here
}
else{ e.cancle = true}

Chuck:

You can refer to the RadUpload Context documentation page which states: "You can access all uploaded files within the current request using the RadUploadContext object. The RadUploadContext object has a single property: UploadedFiles. UploadedFiles is a collection of all files that have been uploaded within the current request."

UploadedFiles is a collection of all valid uploaded files.

This is how you can access the name for each uploaded file for that request, using the "GetName()" property:

foreach (UploadedFile f in RadUpload1.UploadedFiles)
{
    // Get the file name for each file that is uploaded
    string fileName = f.GetName();
    // add logic to store this name in your database
}

Hope this helps!

[Chuck]

Thanks! I'll give that a try. However, what about my second question? How do I test if the RadUpload1 uploaded successfully?

[Dimitar Terziev]

Hi,

In case the UploadedFiles collection of the RadUpload is not empty after you have selected a file for upload, than the file is being uploaded successfully.

All the best,

Hi Telerik team and members , please don't use againfile.GetName() or file.FileName.

I got the solution of this issue, its only arise in IE on few particular computer. After uploading it again and again and checking on client computer. i figure out this. So nobody suffer with again file.GetName() or file.FileName.

This problem is arise due to this: When we getting UploadedFile  name [  file.FileName.ToString() ]
So need to use this
file.GetNameWithoutExtension() + file.GetExtension();
instead of file.FileName.ToString();

string targetFolder = System.Web.HttpContext.Current.Server.MapPath(@"~/TestUpload");
string file1 = file.GetNameWithoutExtension() + file.GetExtension();
string targetFileName = System.IO.Path.Combine(targetFolder, file1);

Thanks,
