In Example 1 from Edit an item outside RadGridView article, we are suggesting to replace an item to trigger collection changed. This way the sorted/filtered collection will be updated. In this case, we are replacing the item with the same one. This will lose the selection after replacing it several times.

The window's content gets clipped when the window goes from Maximized to Normal WindowState. This reproduces only when the window and the screens are using specific sizes. The setup when this was reproduced was with a 1936x1056 size of RadRibbonWindow (in Normal state) and 1920x1080 screen resolution.

To reproduce this the IsWindowsThemeEnabled property of the RadRibbonWindow should be set to False.

To work this around, reset the Window size on WindowStateChanged.

private void MainWindow_StateChanged(object sender, EventArgs e)
{
	if (this.WindowState == WindowState.Normal)
	{               
		Width += 1;
		Width -= 1;
	}
}

In some cases the string values in the XML attributes are not colored with the expected color, but default to black.
 
This was reproduced when there is only single quotation mark on visible on the line. And also if the count of the visible quotation marks on the line is an odd number (not always reproducible).

Cell Values disappearing when RadWindow is dragged to a second Monitor.

Workaround:

    var window = e.CreatedElement as ToolWindow;
    if (window != null)

    }

The content of RadBackstageItem is not stretched within the available area in the content area of the RadRibbonBackstage control. There is a gap between the title bar of the RadRibbonView control and the top border of the content area.

This reproduces with the Material theme, but it is possible to appear also in other themes.

To work this around, you can extract the ControlTemplate of RadRibbonBackstage and re-order the layout in order to stretch the content in all the available space. Check the attached project.
