Code Behind:

 private const string NotificationId = "pageNotification";

    protected void Page_Load(object sender, EventArgs e)
    {
        if (RadAjaxPanel.FindControl(NotificationId) == null)
        {
            RadNotification notification = new RadNotification();
            notification.ID = NotificationId;
            RadAjaxPanel.Controls.Add(notification);
            notification.Show();
            Label1.Text += RadTextBox1.Text;
        }
    }

Adding CSS styles for the table layout via the TableCssLayoutTemplates adds the style element inside the body, which is non W3C compliant content.

Silverlight Module doesn't work correctly with RadProgressArea, when uploading is canceled.

There is a refresh error when a user uploads multiple files on Mac OS 10.8.3 and Safari 6.0.4. After the user selected for example 5 files at the same time and click on the Upload button, you a screen showing only 2 files - http://screencast.com/t/gYiE76M0D

The EnableAsyncUpload property of FileExplorer have to be set to "True".

MetroTouch "DragHandleDown.png" resource appears to be missing from 2015.1.225.40 version of Telerik.Web.UI.Skins.dll.

Got the following in my event logs:

Event message: An error occurred processing a web or script resource request. The requested resource 'pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.MetroTouch.Slider.DragHandleDown.png' does not exist or there was a problem loading it. 

Checked in the .dll for any reference to said resource. Found instances of "DragHandleDown.gif" for other skins (Black, Office2010Black, etc.) but nothing for MetroTouch.

Here is the missing resource name: pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.Web20.Common.radGradientListSprite.png
You can see if this is your case as well by decrypting the WebResource request that fails as shown here: http://blogs.telerik.com/aspnet-ajax/posts/07-03-27/debugging-asp-net-2-0-web-resources-decrypting-the-url-and-getting-the-resource-name.aspx

I want it to be possible to use declarative localization for PagerTextFormat property in RadGrid Control. Currently the only way is by using code behind.
