Dear
I have created a sample solution to mimic our way of working (our solution is very much driven by datatemplates).
If you run the application and press the button to open a window, you will notice that you can maximize the screen. However the button to restore is is faulty.
Do you have any idea what the problem is here?
This is marked as urgent, because we will release in a few days.
Thank you in advance for your assistance.
We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.
Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.
Hi Costin,
The issue was fixed in the DataTemplate with the "dxrt:RibbonThemeKey ResourceKey=FloatingContainerTemplate"key in the RibbonWindow.xaml file. You can correct it manually for your custom theme. Add the following trigger to the DataTemplate.Triggers:
XAML<Trigger Property="dxr:RibbonControlHelper.IsAutoHide" Value="True">
<Setter TargetName="PART_Restore" Property="Visibility" Value="Collapsed"/>
<Setter TargetName="PART_Maximize" Property="Visibility" Value="Collapsed"/>
<Setter TargetName="Part_WindowContent" Property="Margin" Value="0"/>
</Trigger>
Also, find the buttons in the stack panel whose styles have the "dxrt:DXRibbonWindowThemeKey ResourceKey=MaximizeButtonStyle" and "dxrt:DXRibbonWindowThemeKey ResourceKey=RestoreButtonStyle" keys and modify them in the following manner:
XAML<Button Style="{DynamicResource {dxrt:DXRibbonWindowThemeKey ResourceKey=MaximizeButtonStyle}}" Visibility="{Binding Path=(dxc:FloatingContainer.IsMaximized), Converter={dxc:BooleanToVisibilityConverter Invert=False}}" />
<Button Style="{DynamicResource {dxrt:DXRibbonWindowThemeKey ResourceKey=RestoreButtonStyle}}" Visibility="{Binding Path=(dxc:FloatingContainer.IsMaximized), Converter={dxc:BooleanToVisibilityConverter Invert=True}}" />
By the way, this is not a bug because you created your custom theme based on the theme with this bug. We have fixed the bug, but in the custom theme, it still exists. That's why it is necessary to correct the DataTemplate.
Thanks,
Nadya
Dear Nadya,
Thank you for the information.
I made a theme based on a working version. I upgraded using your tool to a version which apparently has a flaw in it. You release a new fixed version and somehow I cannot upgrade my theme to the fixed version.
This … is not my fault. I consider this an issue on your side.
However, thank you again for you assistance in the matter. For me, the issue is resolved :-)
Hello,
As this issue isn't directly related to the original question, I created a separate ticket on your behalf: T311841: How to upgrade a custom theme to the current version after a hotfix was installed. This ticket is currently in our processing queue.
Thanks,
Kirill
As a workaround for people who cannot upgrade immediately, you can use a contentcontrol as a wrapper
C#window.Content = new ContentControl() {Content = viewModel};
Hello Costin,
Thank you for providing the work around for this issue. I believe that it will be useful to other users who might face the same issue.
Thanks,
Elliot
With pleasure! Could someone take a look at my comment on the theme? :-) (see other solution)
Of course, Costin. Please take another moment to review my comment above regarding the issue with the theme upgrade.

Hello,
I've reproduced this issue and forwarded it to our R&D team for further research. Follow our notifications to be informed about our progress.

I see you have changed my question. I would like to point out that the reverse is also true.
Eg if you open the window in a maximized state, you will be able to restore it once. The button will not allow you to maximize it again.
Hello,
Thank you for this point. I've successfully reproduced this issue too and modified the subject accordingly.
Thanks,
