[Julian Pirola]

Im using AsynUpload to upload a file, and an asp button to submit the the process of the file.

<telerik:RadProgressManager runat="server" ID="RadProgressManager1" />
<telerik:RadAsyncUpload ID="rauFileUpload" runat="server" Width="95%"
                        OnClientValidationFailed="validationFailed"
                        AllowedFileExtensions="xls"
                        MaxFileSize="4000000">
</telerik:RadAsyncUpload>
<br />
<asp:button id="btnCharge" runat="server" OnClick="btnCharge_Click" />
<br />
<telerik:RadProgressArea runat="server" ID="RadProgressArea1" skin="Default" ProgressIndicators="TotalProgressBar, TotalProgressPercent">
</telerik:RadProgressArea>

I solve the problem with those double-click-on-buttons users with javasript, disabling the button and forcing a postback

        function enableLoadButton(button)
        {
            button.disabled = true;

            __doPostBack("<%= btnCharge.UniqueID %>");

            return;
        }

<asp:button id="btnCharge" runat="server" OnClick="btnCharge_Click" OnClientClick="enableLoadButton(this)" />

Its solve the problem for some users, other still have the problem.
I try the different configurations of the time persistens of the files and nothing. In some point the uploaded file dissapear and i get the exception.
This occurs after the file was processed, when the response is created and i dont need to access to it anymore.

   Hope u can assist me, ask me if u need more info.

Hi Julian Pirola,

I've transferred this forum post to a product feedback ticket.

I am not able to reproduce the problem. Could you attach here a sample project where the issue is reproduced? We will take a look at what is going wrong then.

Best wishes,

Hello Julian,

I wasn't able to run the provided sample code. To resolve the issue we need to know how to reproduce it locally.
My suggestion is to remove the following code "__doPostBack("<%= btnCharge.UniqueID %>");" from the event handler, because the button will trigger a postback even without that line of code.
After that change please ask your user to reproduce the issue.
