    I am evaluating the ribbon control. I have a button that expands/collapses the ribbon bar by using the following event handler.

    private void OnToggleStateChanged(object sender, StateChangedEventArgs args)  
        ribbonBar.Expanded = !ribbonBar.Expanded;  
    The title bar does not get repainted properly when expanding. I have linked some screen shots that show the problem.

    1. Initial state
    2. Collapsed state
    3. Buggy expanded state

    Hi Blake,

    Thank you for writing.

    I have tried similar scenarios like the described one, but I could not reproduce the issue. I have used the code below:
    private void radToggleButton1_ToggleStateChanged(object sender, StateChangedEventArgs args)  
        if (this.radRibbonBar1.Expanded)  
            this.radRibbonBar1.Expanded = false;  
            this.radToggleButton1.Text = "Expand";  
            this.radRibbonBar1.Expanded = true;  
            this.radToggleButton1.Text = "Collapse";  

    On my side this code is producing correct results. Maybe the issue is related to something specific in your project. It will be very helpful if you could send me a small example that demonstrates the issue. This will help me to investigate your case and to provide you with further assistance.

    I am looking forward to your reply.

    The problem went away when these lines were added:

    officeBlackTheme = new Telerik.WinControls.Themes.Office2007BlackTheme();

    ThemeResolutionService.ApplicationThemeName = "Office2007Black";
