    In my app I am disabling the kendoUpload widget when the user has chosen 5 files to upload.  But - if the user removes one of those files to download, I will enable the kendoUpload widget.

    My issue is that once I call the disable() method in the kendoUpload widget - the next time I try to access the kendoUpload widget it is undefined.

    Here's my function.  

    function setAddAttachmentButton(disable) {
        var kendoUpload = $("#attachmentUpload").data("kendoUpload");
        if (kendoUpload == undefined)
        if (disable) {
        } else {

    This is only happening on IE9 - the other browsers work fine.

    Hello Guillermo,

    I am not sure that I understand the current scenario. When the Upload widget is disabled, the user cannot remove any files. This behavior could be observed in the API demo. Additionally in the mentioned demo I tested to disable and then access the widget in IE 9 and it works as expected.

    Could please provide some additional information if the problem is persisting so I could assist you further?
