UploadBox and Ajax

[Kathy Gray]

I am using the UploadBox within an ajax UpdatePanel. But, whenever I upload the file, it fails to trigger the FileUploaded event. I have tried naming the procedure in the "OnFileUploaded" option in the aspx page, and also just handling it in the code behind. I just can't seem to catch it. Is there a problem using UploadBox with Ajax?

Yes. You can able t o use the asp:fileupload with callback panel. But the page is refreshed during the upload button click, even when the file upload placed inside the callback panel. The issue mentioned here is suspected to be a defect and we have sent this to our development team for more analysis.

Hi Kathy,

On further analysis we found that the issue of "UploadBox FileUploaded event is not fired when the UploadBox placed inside the Ajax update panel" is not a defect. FileUploaded event was not fired, because file was not uploaded. There is only one mechanism to implement file uploading - add html file input element inside a form element, select file(click file input browser button) and do form submit. Ajax updatePanel intercepts submit of form, and sends own asynchronous postback, so file can not be uploaded. Please refer below link for more details:

Please let me know if you have any other questions.

Thanks,
Melba

Hi Eric,

We regret for the inconvenience.

Based on the forum discussion, we suggest you to use PostBackTrigger option of UpdatePanel control for triggering UploadBox events.

                                      

By assign ControID to PostBackTrigger property, we can trigger the corresponding server side event automatically. Please refer the below code snippet:

<code>

[ASPX]

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

                <ContentTemplate>

                    <syncfusion:UploadBox ID="upload1" runat="server" OnFileUploaded="upload_FileUploaded"></syncfusion:UploadBox>    

                </ContentTemplate>              

                <Triggers>

                    <asp:PostBackTrigger ControlID="upload1" />

                </Triggers>

            </asp:UpdatePanel>

</code>

We have prepared a simple sample to exhibit this behavior and it is available in the below link:

Kindly try the sample and let us know if you have any queries.
