From customer feedback:

There should be client methods for completely hiding (in contrast to collapsing) ribbon groups.

There is vague information in the Microsoft Ribbon Framework about the Ribbon in RTL mode. Still with the release of Win8, the RTL story seems more and more likely.

Currently, the ribbon groups are resized automatically, from right to left.

The MS Ribbon Framework specifies a property to set the order of the group reduction -- GroupSizeReductionOrder.

-- http://msdn.microsoft.com/en-us/library/microsoft.windows.controls.ribbon.ribbontab.groupsizereductionorder.aspx

Unlike the rest of the Ribbon Items, the Templates have only one level of resizing, where as they need few steps more, to be consistent.

Add proper (fluid) resizing to templates by implementing template size.

Based on customer feedback:

When the application menu of the Ribbon bar is opened and should cover external applets / plugins, such as JavaApplets, PDF, Flash etc, it's not rendered on top, but beneath.

The solution is to add an IFRAME element, a lot like in the menu, combo etc, for IE browsers.

For the time being you can use the ApplicationMenu withing the RadRibbonBar control.

KeyboardNavigationSetting property Activated does not work, when set to True:
- JavaScript error thrown when KeyboardNavigationSetting Activated is set to true in Classic render mode.
- Nothing happens in Lightweight render mode.

In lightweight the issue is not observed:

<telerik:RadRibbonBar runat="server" RenderMode="Classic">
    <Tabs>
        <telerik:RibbonBarTab Text="home">
            <%-- duplicate the group and items inside to replicate more easily --%>
            <telerik:RibbonBarGroup Text="Documents">
                <Items>
                    <telerik:RibbonBarButton Text="Item 1" />
                </Items>
            </telerik:RibbonBarGroup>
        </telerik:RibbonBarTab>
    </Tabs>
</telerik:RadRibbonBar>

Hi,

Seems like the RadRibbonBar1.LoadContentFile doesn't support AuxiliaryPane and FooterPane in the .XML file:

<AuxiliaryPane Header="Latest files">
			<ContentTemplate>
				<ol>
					<li>Powder.jpg</li>
					<li>Free jump.jpg</li>
					<li>Downhill.jpg</li>
					<li>Snowboarding.jpg</li>
					<li>Moutain top.jpg</li>
				</ol>
			</ContentTemplate>
		</AuxiliaryPane>
		<FooterPane>
			<ContentTemplate>Skiing.png</ContentTemplate>
		</FooterPane>

I have a lot of exceptions "This is an invalid webresource request" on URL:

I decoded content of url:
Telerik.Web.UI.Skins|Telerik.Web.UI.Skins.Web20.Common.radGradientListSprite.png
Probably there is no radGradientListSprite.png for Web20 skin inside dll file.
Could you check it?
