You could even use a ContentControl instance as the ScreenTi... 2024-03-21T19:37:37Z 14fc5aee-3dd2-4797-a463-c68d6831e02b-122222 Is there any way i can write my own custom ui template (instead of plain text) for ribbon:ScreenTipService.ScreenTipDescription !? It being a DependencyObject/object type.. Any sample example ? ... 2024-03-20T23:26:35Z 590867d2-41a4-4fdc-8222-3459ecd6fdcd-122212 The classic Ribbon product's SplitButton has an element in its template with name "PART_Button".

If i... 2024-03-15T17:25:35Z 590867d2-41a4-4fdc-8222-3459ecd6fdcd-122211 What about on Preview mouse down events. How will we distinguish!? 2024-03-14T18:01:01Z d94b0bb8-cfe1-4e4a-aac2-1c5f2af28682-122144 Hi! Somehow a normal tree view was the problem. Somehow after a popup appears the tree view cicle thru IsSelected (this was bind 2 ways) a lot of times making the application so much slower. Ki... 2024-02-17T21:41:56Z d94b0bb8-cfe1-4e4a-aac2-1c5f2af28682-122140 Hi Daniel, I'm sorry you're having trouble. We aren't aware of anything like the slowdown you mentioning, at least in the latest version. Are you on v23.1.4 as indicated by your original post, ... 2024-02-16T20:46:38Z d94b0bb8-cfe1-4e4a-aac2-1c5f2af28682-122139 It seems that the problem might appear when also the popup for a ribbon button appears and even without the OpenTK control. 2024-02-16T12:18:04Z d94b0bb8-cfe1-4e4a-aac2-1c5f2af28682-122138 Hi! I have an application with ribbon, docking and everything. This application can do some intensive calculations and it works good but when I hover some ribbon buttons and the screen tip appe... 2024-02-16T11:55:43Z 15fdab10-5199-4fbc-838f-7d8a574a1d2e-122127 Hi Farris, The "old" way with the large orb in a cirlce is no longer possible in the more recent versions. If I understand you correctly, your original concern was having both the Windows Appli... 2024-02-08T18:46:58Z 15fdab10-5199-4fbc-838f-7d8a574a1d2e-122124 Previously my application only had 1 large icon in the top left corner, which toggled the Backstage / ApplicationMenu, and no default Windows Application Icon in the titlebar was displayed, like in... 2024-02-08T15:07:17Z 068a739b-0554-471b-a444-14c615b0c30e-121941 Hello, You could do what was suggested above with the implicit Style for QuickAccessToolBar. You could probably even have it in the Resources of the UserControl or whatever your control root is. 2023-11-29T18:47:51Z 068a739b-0554-471b-a444-14c615b0c30e-121940 I ask that question because maybe some client wants my control inside a window or control and they might have other wpf controls library. 2023-11-29T11:08:32Z 068a739b-0554-471b-a444-14c615b0c30e-121938 Hello, The above QAT Background is always set to Transparent. It's just that some of our themes for Windows via WindowChrome may have different title bar area backgrounds than the Window's conte... 2023-11-28T21:28:51Z 068a739b-0554-471b-a444-14c615b0c30e-121937 Hi! I have a control with ribbon, tool windows and everything. The problem is if some person wants to use my control, it needs to have the parent window style based on actipro window style or to ... 2023-11-28T08:37:36Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121935 Hi! I seems that the problem was that all the image setters where behind data triggers. If I add a setter directly inside the Style it works. Kind regards, Daniel 2023-11-27T12:08:33Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121932 Hello, Regarding the images, we still are not able to reproduce that issue in our Customizing the QAT sample. Can you please give us exact steps in that sample to make it happen so that we can s... 2023-11-22T20:56:47Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121931 Also the problem is only on the right collection, after the cloning, inside Customize QAT. If I save the QAT and open again the Customize QAT dialog, all the buttons will have correct images. 2023-11-22T07:46:22Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121930 Hi! Thank you! About the images it seems that maybe the cloning is the issue. UIElement clonedControl = controlRef.Clone(); The clonedControl has ImageSourceLarge and ImageSourceSmall null ... 2023-11-22T07:44:02Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121929 Hello, Here is what I tried just now. In v23.1, I opened the Customizing the QAT sample's MainControl.xaml and updated the Ribbon.ApplicationMenu to be: <ribbon:Ribbon.ApplicationMenu> ... 2023-11-21T20:24:40Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121928 Fot the images not showing in the Customize QAT. I can see the image on the left collection (available qat items list box) but after I press the button to add on QAT, I can see the button on the le... 2023-11-21T13:56:21Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121927 Hi! The version is indeed 19.1.0687 and I add the buttons via the Customize QAT like in the Sample Application. I implemented the same as in the Customize QAT example. It finds all the ribbon b... 2023-11-21T07:12:24Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121925 Hello, Which exact v19.1 build were you using? I tried putting a ribbon:Button on a Backstage tab in v19.1.0687 (latest v19.1 maintenance release) to see if I could add it to the QAT and there i... 2023-11-20T21:19:43Z 3bbe4ac0-7384-465e-bde1-3e5dc64a0080-121921 Assuming I really need this working, it is somehow a way to make it work? I would not want to remove functionalities which were working before the migration to the new libraries. 2023-11-20T12:32:17Z
