Titlebar of RibbonWindow is black and has no controls when Ribbon is in it

[Victor Dienstbier]

Hi everybody,

there is a problem using Ribbonwindows for me. When I change the window from Window to Ribbonwindow everything is fine but as soon as I add a ribbon the titlebar changes to black and has no more controls in it.

Is there anything I have to change?

Hi Victor,

Thanks for contacting Syncfusion Support.

Based on your provided information, we have checked the reported scenario with our working sample but we are unable to reproduce the reported issue in our side. We have prepared a sample and video for your reference and it can be downloaded from below location. 

Sample: WPF_RibbonWindow_TitleBarIssue_Sample  

Video: WPF_RibbonWindow_TitleBar_Issue_Video  

Also instead of black background we are getting white background from our side only in the below cases.

1. If any of the required assemblies are not properly added in the application. For example when applying office 365 theme, “Syncfusion.SfSkinManager.Wpf.dll” ,“Syncfusion.Themes.Office365.Wpf.dll” must be included.
2. If we override the style or export the themes from theme studio in App.xaml (globally) file and not properly set RibbonWindow.Style property  using the key of overridden style. 

Please check with the sample and video and let us know if we have misunderstood your query. If possible, can you please share the additional information such as currently using version of Essential Studio or else modify the above sample which replicates the issue? It will helps us to provide the solution at earliest.  

Please let us know if you need further assistance.

Sabaridass R

Thank you for the quick reply!

Maybe I found the reason for the problem with you help:

When I deleted the xaml code skinmanager:SfSkinManager.VisualStyle="Office365" the window was shown correctly.

I saw that in the code behind automatically the following code behind of the window was inserted when I created the project:

public partial class MainWindow : RibbonWindow

    {

#region Fields

        private string currentVisualStyle;

        #endregion

        #region Properties

        /// <summary>

        /// Gets or sets the current visual style.

        /// </summary>

        /// <value></value>

        /// <remarks></remarks>

        public string CurrentVisualStyle

        {

            get

            {

                return currentVisualStyle;

            }

            set

            {

                currentVisualStyle = value;

                OnVisualStyleChanged();

            }

        }

        #endregion

        public MainWindow()

        {

            InitializeComponent();

this.Loaded += OnLoaded;

        }

/// <summary>

        /// Called when [loaded].

        /// </summary>

        /// <param name="sender">The sender.</param>

        /// <param name="e">The <see cref="RoutedEventArgs"/> instance containing the event data.</param>

        private void OnLoaded(object sender, RoutedEventArgs e)

        {

            CurrentVisualStyle = "Office365";

        }

/// <summary>

        /// On Visual Style Changed.

        /// </summary>

        /// <remarks></remarks>

        private void OnVisualStyleChanged()

        {

            VisualStyles visualStyle = VisualStyles.Default;

            Enum.TryParse(CurrentVisualStyle, out visualStyle);            

            if (visualStyle != VisualStyles.Default)

            {

                SfSkinManager.ApplyStylesOnApplication = true;

                SfSkinManager.SetVisualStyle(this, visualStyle);

                SfSkinManager.ApplyStylesOnApplication = false;

            }

        }

        private void _mainWindow_Closed(object sender, EventArgs e)

        {

            Application.Current.Shutdown();

        }

    }

I guess this might be the problem...

Hi Victor,

Thanks for the update.

We are able to reproduce the reported issue - “Black background around the RibbonWindow Titlebar”  from our side only when set “SfSkinManager.ApplyStylesOnApplication” as true.  Currently we analyzing the root cause for this problem  and provide you more details on April 26, 2019.

From your update, you have applied the office 365 theme in both designer and code behind. So kindly update us the reason for applying the theme twice which could be helpful for us to provide the solution at earliest.

Please let us know if you require further assistance.

Sabaridass R 

[Victor Dienstbier]

Hi!

There is no reason for applying the Skin twice :-)

I created the Project with the help of your wizard in Visual Studio. I didn't check if there is Code behind in the window, because I try to do everything in MVVM...

If just seems to not work Setting both.

Best wishes

Victor

[Jagadeesan Pichaimuthu]

Hi Victor,

Thanks for the update.

As we updated earlier, we will provide you the analyzed details of the reported problem on April 26, 2019. In the meantime, we suggest you to apply the Office365 theme only once in your application either designer or code behind to resolve the reported issue.

We appreciate your patience until then.

Regards,
Jagadeesan
