    Hi Goxel,

    Have you found the solution for radajaxpanel problem.

    I have the same problem. i want to convert uploaded file into stream bytes and send to across the database using rad upload. I have been facing the problem with RadAjaxPanel and RadUpload controls.

    Any help would be appreciated.

    Thanks in Advance

    Hi Durga,

    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. Unfortunately, at this moment there is no workaround to this. You cannot use AJAX behavior while uploading files.

    Kind regards,

    Hi i am using a radUpload control in a ajaxify panelbar. I came to know across seeing many forums since there is no post back the upload control always gives the count as "0". Later when i searched across i got a link which said how to used the upload control in the ajaxify panel bar. I tried the way but didn't get any changes. The link is

    in the topic "Alternative workaround for RadAjaxPanel (and RadGrid classic)"
    I have a doubt in this code.. the CodeBehind says to create a click event..

    protected void Page_Load(object sender, EventArgs e)
    if (!IsPostback)
    string.Format("realPostBack('{0}', ''); return false;", ButtonSubmit.UniqueID));

    The script code is

    function realPostBack(eventTarget, eventArgument)
       __doPostBack(eventTarget, eventArgument);

    Why do we send a single argument. i mean we just send the eventTarget  and get eventArgument  also which is always null. I am not clear in this.. if some one gets this to work please help me out in this as i am stuck in it.. and more over the solution given here is not working for me. :(

    Sorry i mistakenly happen to open a new thread..

    thanks in advance

    I have a RadUpload inside a RadAjaxPanel. To get around the known issues with this I used the workaround here: ...which effectively disables AJAX for my submit button.

    This has left me with just one problem - when I click my submit button, at the bottom of a longish page, to commit my uploads to the database, this causes a full postback and the page reloads, losing the place at the bottom.

    I'm in a position where I can't change the layout of the page, so effectively I need the submit button to maintain scroll position on postback (across all browsers)..

    Any advice would be greatly appreciated.

    Hello Gordon,

    Try setting MaintainScrollPositionOnPostback="true" property in the Page derective.
    This way the page should be scrolled to the bottom automatically after the postback.
    I hope this would solve your issue.

    All the best,
