    Dear deepakkumarjoshi,
     
    Please save the following snippet to "test.aspx", and then run it, it works fine.

        }
        void Attachments1_AttachmentAdded(object sender, AttachmentItemEventArgs args)
        {
            InsertMsg(args.Item.FileName + " has been uploaded.");
        }
        void ButtonDeleteAll_Click(object sender, EventArgs e)
        {
            InsertMsg("Attachments1.DeleteAllAttachments();");
            Attachments1.DeleteAllAttachments();
        }

    Re: global functions not firing

    Hi,
     
    The global handler is called by the default instance handler.
     
    If you replace the default instance handler, the global handler will not be called.
     
    So you need do that in the instance handler :
     
    uploader.handlepostback=function()
    {
       var res;
        if(window.CuteWebUI_AjaxUploader_OnPostback)
             res=window.CuteWebUI_AjaxUploader_OnPostback();
        if(res===false)
        {
            ///
        }
        ///
    }
     
    or this style :
     
    var oldhandler=uploader.handlepostback;
    uploader.handlepostback=function()
    {
       var res=oldhandler();
        if(res===false)
        {
            ///
        }
        ///
    }
     
    Regards,
    Terry
