When you have set the Windows task bar to auto-hide and you maximize an RadRibbonWindow, you are not allowed to visualize the task bar on top of the RadRibbonWindow.

When the Taskbar is auto-hidden, if the RibbonWindow is maximized, the task bar cannot be displayed.

Title bar (including the Contextual tab header) goes over the Window (MinMaxClose) Buttons

We have a RadRibbonWindow.
When it is run on Windows XP (or on Windows 7, "Windows Classic" theme) and the DPI settings are high (above 170 %), the standard window buttons (Minimize, Restore and Close) are not displayed properly (they are cut). Also there is too much space between them.

Output error in VS:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.RadRibbonView', AncestorLevel='1''. BindingExpression:Path=IsHostedInRibbonWindow; DataItem=null; target element is 'WindowTitle' (Name='WindowTitle'); target property is 'NoTarget' (type 'Object')

When ribbon is placed on two monitors the minimized popup is misplaced.

The Title of the RadRibbonWindow is not diplayed unless there is a RadRibbonView in the window.

You can not click the ColorPicker when it is inside a RadRibbonSplitButton.

TreeView or DataGrid, or COmbobox is placed in a dropcontent of a RibbonDropDownButton. Item is selected programmatically before the dropdown is loaded. This leads to null reference exception.

The BackstageItems are not rendered as expected when the RadRibbonView is hosted in apanel with flow direction set to right to left.

The title of the RadRibbonWindow can't be trimmed when resizing the window. Even the window's buttons are overlapped

Setting the KeyTipService.AltAccessText attached property on a RadRibbonGroup element should display a keytip on the dialog launcher of the group, when the keytips are activated.

Currently, if the group is collapsed, you can expand it using its AccessText. However, in this case the keytip of the dialog launcher is not displayed.

To work this around, subscribe to the Loaded event of RadRibbonGroup and set the KeyyTipService.AccessText property directly to the RadRibbonButton representing the dialog launcher.

private void RadRibbonGroup_Loaded(object sender, RoutedEventArgs e)
{
	var group = (RadRibbonGroup)sender;
	var button = group.ChildrenOfType<RadRibbonButton>().FirstOrDefault(x => x.Name == "DialogLauncher");
	if (button != null)
	{
		KeyTipService.SetAccessText(button, "D");
	}
}

RadRibbonDropDownButton DropDownIndicator isn't rotated when the DropDownButtonPosition is Right and the DropDownPlacement is Right

When the Title property is set to "" the RibbonView displays the ApplicationName two times. If the Title is set to null via binding the control displays the ApplicationName three times.

The problem doesn't occur when the RadRibbonView is hosted in a vanilla Window.

When the component is hosted in a RibbonWindow and its CollapseThresholdSize is modified, if the BackstageMenu is opened on start-up, the TitleBar of the RibbonView is misaligned. Instead of displaying in the RibbonWindow title bar, it initially displays underneath it. Once you close the Backstage, the title bar is moved in the Window's TitleBar.

In scenarios with more than one monitor when the RibbonWindow is run on 64bit process and e.g. using VBE7.dll, the WM_NCHITTEST message, which is sent to the window in order to determine what part of the window corresponds to a particular screen coordinate, could provide lParam with value which overflows Int32.
