I ended up rewriting the commands, except for rename where I used your suggestion, which works well. To clarify, I wasn’t trying to execute those commands from a tool... 2025-09-05T12:11:46Z 874ec6be-dfde-4cc6-9e42-57ffc0ee88cc-123126 Hi Benjamin, To confirm, it sounds like you have already overridden ShellObjectItemAdapter and are customizing the context menus that are displayed, correct? Unfortunately the WindowsShellMenuI... 2025-08-29T20:06:19Z 874ec6be-dfde-4cc6-9e42-57ffc0ee88cc-123125 Hello,I'm using ShellTreeListBox and I want to customize the context menu on items.

We found that it seems to be due to some menu items coming into the shell menu in a delayed fashion, so the second menu may have a couple additional items. We ... 2025-06-23T14:07:48Z 8ebf84f4-5f2e-49da-97f7-a9699634fdb0-123023 If I right click on a folder in the tree and choose "open", the context menu closes and nothing happens. If I do that again the folder opens in file explorer as expected.

The UI thread taking a little longer than normal do work... 2025-05-28T19:28:49Z a5cafb51-d280-4922-8594-21ce17edec67-122977 Hi Ben, The ShellObjectItemAdapter.ChildrenQueryModeDefault property is set to TreeItemChildrenQueryMode.OnExpansion by default, which means it only populates children at all when you expand the ... 2025-05-28T17:28:33Z 52bba608-b4f3-4a1f-a5a3-3c4a8b26df03-122976 I noticed that when I add the Shell components to my view, when I open the view the screen will flash black.

If that is not the case, which one are you on? And I would definitely suggest trying v24.1.3 to see if ... 2024-09-23T16:21:25Z b5ec00e7-04bb-49ea-a449-8fd2719b1948-122582 As mentioned above, this was the exception when we debugged the crash dump:Unhandled exception at 0x00007FFB5ACBB699 (KERNELBASE.dll) in FlexFtp.exe_240917_133453.dmp: 0xC000041D: An unhandled exce... 2024-09-20T23:51:36Z b5ec00e7-04bb-49ea-a449-8fd2719b1948-122581 Hi Rex, Could you tell us what the exception type or message was? We aren't aware of any issues with that method's logic. Do you have a way to reproduce it? 2024-09-20T18:05:46Z b5ec00e7-04bb-49ea-a449-8fd2719b1948-122580 Our customer has reported a crash: Unhandled exception at 0x00007FFB5ACBB699 (KERNELBASE.dll) in FlexFtp.exe_240917_133453.dmp: 0xC000041D: An unhandled exception was encountered during a user ca... 2024-09-20T06:30:30Z 9eb4f31d-b692-4f9f-8775-54ebeb5c11b5-122446 Hello, I'm sorry you're having trouble. The first thing I'd look at is whether you have configured the themes correctly. Also, if you are loading the WPF library from a non-WPF app (I'm not s... 2024-07-03T19:16:30Z 9eb4f31d-b692-4f9f-8775-54ebeb5c11b5-122445 Hi, I'm having an issue with the ShellListView control. The control works correctly when I create a classic WPF application. However, when I add a WPF window to a library and try to display that ... 2024-07-02T22:12:44Z 3ad9f857-370b-464b-9c5e-733967ef84ba-122413 Hi Dirk, Thanks for reporting this. We already special case ZIP files to be treated like files instead of expandable archive folders for the same reason and will update the logic to do the same ... 2024-06-25T18:47:44Z 3ad9f857-370b-464b-9c5e-733967ef84ba-122408 Since Windows 11 has native support for RAR archives (extract only) the TreeListBox shows the content of RAR archives, just like their were folders. But for the content files, native context menu ... 2024-06-25T06:35:20Z 06d9424f-4f6e-4da0-aa3e-55f7031bbd6f-121738 Thank you for the suggestion, we'll write it down. 2023-08-23T16:45:41Z 06d9424f-4f6e-4da0-aa3e-55f7031bbd6f-121736 Since an implementation may not necessarily need to be coupled to a TreeListBox, introduce an overload that allows arguments that provide the same data needed from the TreeListBox in order to rende... 2023-08-22T19:49:51Z 389d01b6-21da-4a51-ad91-7b4cf87972aa-121631 Hi Rex, Thank you for posting the GUIDs, that really helped.

Do you perhaps have multiple OneDrive accounts, such as work and home ones? Could you go to the ShellTreeListBox Intro sample and do a t... 2023-06-14T11:49:42Z 389d01b6-21da-4a51-ad91-7b4cf87972aa-121624 Both "Documents" point to the OneDrive documents.

We've fixed it for the upcoming v23.1.1 maintenance release, which should be out very soon. 2023-06-12T17:40:40Z 6415f9a6-541a-49bc-9cba-1bcd3cc5f3de-121611 ShellListView BringItemIntoView has no effect when LayoutMode=List.

That's why they get stored in properties on th... 2022-10-26T19:38:05Z 43250675-cd71-45e2-a648-4a239cd383a5-121021 I'm not sure this is worth a large breaking change, tbh. I can think of a couple of other ways you might do this: 1) Add a new ShellListLayoutMode of 'Content', which uses 32px images. Of cou... 2022-10-25T23:27:29Z 43250675-cd71-45e2-a648-4a239cd383a5-121020 Hi Rick, Thanks for the sample. The problem here is a little complex. We can get the icons in 16, 32, 48, and 256 size from the Windows shell image list. However our shell object image sizes h... 2022-10-25T20:55:35Z 43250675-cd71-45e2-a648-4a239cd383a5-121018 I emailed a sample project.

Are you able to reproduce this with one of our Shell samples? If so, please tell us how. Or if not, please make a new simp... 2022-10-24T20:05:00Z 43250675-cd71-45e2-a648-4a239cd383a5-121016 I’ve been migrating from directly calling OS functions in my app to the use of Actipro Shell.

Could that be what's going on here, or did you specifically set the control to include files as well (not the default)? 2021-02-08T21:40:30Z 672acd1c-b34b-40b2-9e6f-e3d86ae6f103-119096 On ShellTreeListBox I'm using a simple StringFilterBase filter.

Yes the IShellObject.IsFolder property determines... 2020-11-18T21:34:08Z 98b34193-c0a4-4033-8136-528914b44f4f-118816 Thanks for your answer! It seems I may have been to general about some details of my issue though. My apologise. I am working in the File Explorer Demo (Its a very nice demo) and I am adding a cu... 2020-11-18T16:15:47Z 98b34193-c0a4-4033-8136-528914b44f4f-118814 Hello, If you take a look at our File Explorer demo, you'll see how we implemented this kind of setup for the Windows shell. All we do is set the ShellTreeListBox.RootSpecialFolderKind, but yo... 2020-11-18T15:26:21Z 98b34193-c0a4-4033-8136-528914b44f4f-118813 Hi, and thanks for your time. At its core, what I want to do is have the ShellListView work the same way the default RootSpecialFolderKind="Computer" works, where files are displayed in the Shell... 2020-11-17T20:58:09Z 9dc6e146-36d9-4cbc-955f-4c9c6c567921-118683 Just sent. Thank you! 2020-10-02T00:36:13Z 9dc6e146-36d9-4cbc-955f-4c9c6c567921-118679 Hi Rex, I tried adding 100,000 items in our CustomShellObjects QuickStart's CustomShellService and it happened in a matter of milliseconds. We can look into this further but would probably need ... 2020-10-01T13:56:55Z 9dc6e146-36d9-4cbc-955f-4c9c6c567921-118675 I am using the Shell to display an FTP site folders structure which works well until just now when I ran into an FTP site that has 90000 folders. After I retrieve the list of files from the ftp s... 2020-10-01T06:04:11Z 3a91f3e3-0dff-4b7d-bac7-f8d5d947434d-118658 Hi Rex, Thanks for letting us know. We've made a code change to help with this for the next maintenance release. 2020-09-28T19:50:04Z 3a91f3e3-0dff-4b7d-bac7-f8d5d947434d-118656 To see the bug, run the "Browse for Folder" demo. Choose any one of the sub-items such as Camera Roll under Libraries, the "Make New Folder" should be allowed. 2020-09-28T01:15:06Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118463 Excellent! Thank you very much! 2020-07-28T23:43:19Z 737307a3-23b1-4ce2-b23b-fafffee4827b-118462 Great! Thank you! 2020-07-28T23:41:15Z 737307a3-23b1-4ce2-b23b-fafffee4827b-118461 Hi Rex, That's odd that the core shell info objects we call don't return the path for the shell libraries. We were able to special case these 6 libraries to do a different lookup to retrieve the... 2020-07-28T19:54:47Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118457 Hi Rex, After some researching via performance profiling, we found that 55% of the time is spent in the List<T>.Sort call tree. A lot of that is where the comparer is calling into the shel... 2020-07-28T18:17:56Z 737307a3-23b1-4ce2-b23b-fafffee4827b-118458 Thanks. I think there are ways to get even those paths: https://www.codeproject.com/Articles/878605/Getting-All-Special-Folders-in-NET 2020-07-28T06:37:18Z 737307a3-23b1-4ce2-b23b-fafffee4827b-118455 Hi Rex, We call the same shell API to retrieve the FileSystemPath for those logical "library" folders but the calls return an invalid argument HRESULT for them, so they result in null value in ou... 2020-07-27T23:05:28Z 737307a3-23b1-4ce2-b23b-fafffee4827b-118454 Shouldn't the IShellObject's of ShellObjectKind.Library has the FileSystemPath filled instead of null? I think the followings should have values for their FileSystemPath: CameraRollLibrary,Docu... 2020-07-27T03:00:40Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118453 Sure. Thank you! 2020-07-24T23:55:14Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118452 Hi Rex, We will have to do some in-depth debugging to see what the root cause is and how we can improve it. It will probably take several days to dig into this, but we'll reply back when we have... 2020-07-24T19:51:25Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118450 Thanks. This works. However, I just realized that the Shell code is rather unefficient. If I set the initial path to "C:\Windows\System32\" which has about 3000 items. Without setting the Sor... 2020-07-24T00:58:18Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118447 Hi Rex, Thanks for reporting this. Please try downloading a new preview build at the same URL we gave you before. That has some code updates in it that hopefully resolve this. Kindly report ba... 2020-07-23T21:25:38Z 94689fde-634d-47c5-915b-93e9c3682d6d-118443 Thanks. "Updated" instead of "ChildUpdated" makes more sense. 2020-07-22T23:48:05Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118442 Thanks. I tried and it sets the sort column correctly as indicated by the arrow on the column header but the items are not actually sorted. It seems it is still always sorted by the Name property. 2020-07-22T23:47:04Z dc30590b-dfb8-4216-a0ec-5575e6a05205-118439 Hi Rex, Each Windows shell folder has its own list of properties that are available to be listed in columns. We query the shell to see which to show. Then we choose the properties that are comm... 2020-07-22T17:13:41Z
