Title Templates when RadPane in different situations

Hi,

I am trying to get titletemplates to work depending their associated RadPane docking positions within a RadDocking control. The title template should contain a button next to the header which I have set correctly if the RadPane is docked and visible.

However, if the panel is unpinned/closed or floating I need to hide the button. How do I achieve this? Currently I have a bad workaround which checks FindAncestor for type AutoHideArea, ToolWindow or RadPaneGroup in a Visibility Binding for the button.

Could anyone please suggest a better way for me to check what the RadPane's current state would be within a separate template for titletemplates?

Thank you.

How to apply Theme ColorVariation for a specific control

Hello,

I am trying to make a change theme at runtime popup window. Inside the window, I list all the available themes and color variations, and when the user makes the selection, right below I have a little Panel which works like a Theme Preview, and I am applying the theme (removing and re-adding all theme related resource dictionaries) for that specific control. Everything is fine up to here, but when I try to use LoadPreset like;

VisualStudio2013Palette.LoadPreset(VisualStudio2013Palette.ColorVariation.Dark)

It changes all the application wide color variation/theme. I only want to apply that color variation to just that specific control. I could not see any overload of LoadPreset which takes the control as a input parameter. So how can I achieve this?

Thanks.

MainWindow "frozen"

Hi,

we had UI.for.Wpf version 2016.3.1024 before and we updated to 2018.1.122. We started to have problem after update.

Scenario: We have background worker which starts long running operation. When it finishes, we do some actions in WorkerCompleted event handler. We show RadWindow. When its closed, we do some data refresh there and then we programatically change tab in Ribbon to show user final list with results.

Then app seems to be frozen. Better to say, it is shown on screen, but I can click on items behind window. fe if there is desktop behind, I can manipulate items on desktop.

Steps to unfreeze: Click on application incon in task bar. App gets minimized. Then click on that icon again and app gets maximized. App is then working fine again.

Unfortunately, its so rare that we cant debug it or at least create some demo for you. So, we dont know what is suddently causing this. Our observation is that it happens on Win 10.

Question is now, what can we do to prevent this strange behavior? sure, we can downgrade previous version we used. Any other suggestions? Can you help us please?

No Visual State Changes with GridViewGroupPanel

Greetings,

I need to slightly change the GridViewGroupPanel of the WPF GridView to include a close button. After creating a copy of the GridViewGroupPanel Style via Visual Studio, it seems that the visual state changes are no longer firing. I've made no changes to the style after the copy was created, and I can see that the copy contains the visual states for changing the panel text after groups are added, but it doesn't change after dragging a column to the group bar.

Was wondering if perhaps I was missing something? I wouldn't think creating a copy of the control style (no modifications) would disable the visual states..
