[Solved] Client size check problem - OnClientProgressUpdating is not called!

[Mehmet Ali Ozenci]

I tried to use the approaches on your document at http://www.telerik.com/help/aspnet-ajax/upload_howtoclientfilesize.html but couldn't make the code work!

I want to check the file size on the client (I want to limit the upload to 5 MB) but the javascript function cannot even be called (I place an alert code and nothing happens)

Could you please advise me what to do?

Here are excerpts from my code:

<table cellpadding="0" cellspacing="0">
                                    <tr>
                                        <td align="left" valign="top">
                                            <telerik:RadUpload ID="ruAttachment" runat="server" OverwriteExistingFiles="True"
                                                AllowedFileExtensions=".doc,.docx,.xls,.xlsx,.ppt,.pptx,.txt,.pdf,.mov,.wmv,.mpg,.avi,.wma,.mp3,.jpg,.gif,.png,.bmp"
                                                Width="300px" MaxFileInputsCount="1" ReadOnlyFileInputs="True" ControlObjectsVisibility="None"
                                                EnableEmbeddedSkins="False" Skin="Vinsume" MaxFileSize="2147483647" />
                                            <telerik:RadProgressArea runat="server" ID="rpaAttachment" OnClientProgressUpdating="checkUploadedFilesSize"
                                                Language="">
                                                <Localization Uploaded="Uploaded"></Localization>
                                            </telerik:RadProgressArea>
                                            <telerik:RadProgressManager runat="server" ID="rpmAttachment" />
                                        </td>
                                    </tr>
                                </table>

<script language="javascript" type="text/javascript">


        function checkUploadedFilesSize(progressArea, args) {
            alert("fgdfgdf");
            //progressArea.confirmed is a custom variable,
            // you can use another if you want to
            if (!progressArea.confirmed &&
                args.get_progressData().RadUpload.RequestSize > 1000000) {
                if (confirm("The total size of the selected files" +
                 " is more than the limit." +
                 " Do you want to cancel the upload?")) {
                    progressArea.cancelRequest();
                }
                else {
                    progressArea.confirmed = "confirmed";
                }
            }
        }

    </script>

OK now everything seems fine. I just had to add the corresponding maxallowedcontentlength property to the web.config to be used by IIS7 :)
