  Hello,

  I am experiencing an issue with the C1 Controls that utilize dropdowns/popups. These controls work completely fine for me on the browsers OperaGX and Firefox but they are not working on Google Chrome and Microsoft Edge.

  On Chrome and Edge, the dropdown will appear, but as soon as I try to interact with it the dropdown will disappear and the selection will not be applied.

  Some Components I have seen this happen to:
  
  - C1DatePicker
  
  - C1DateTimePicker
  
  - C1Menu (specifically nested menus)
  
  - C1ComboBox
  
  - Column actions on a FlexGrid(clicking three dots on column header)

  I have the 2025v1 Version of Blazor Controls installed.
  
  The NuGet package version is: 10.0.20261.33

  Hello,

  This issue has already been reported to the development team and has been addressed internally. The fix will be available in the upcoming 2026 v1 Hotfix 1 build. [Bug Tracking ID: C1XAML-39803]

  The issue was introduced by recent Chromium updates affecting CSS pseudo-class handling. As a result, it is expected to occur in the latest versions of Chrome/Edge, while Firefox/OperaGX will not be affected.

  Regards,
  
  Uttkarsh.

  My license only gives me access to version 2025v1(1077) and below.

  Will there be a fix released for the version that I have access to, or will there at least be a way in which I could implement the fix on my end?

  Thanks for the help.

  Hello,

  Regarding your statement:

  → “My license only gives me access to version 2025v1(1077) and below.”

  If the version displayed in License Manager for your activated key is 2025v1, then your license is valid for up to the 2026v1 release, including all 2026v1 Hotfix builds.

  To verify this on our end, we’ll need your license key. Could you please open a ticket through our private support portal, reference this case, and include your license key? We’ll check our records and confirm whether your key is eligible for the 2026v1 Hotfix 1 build.

  The issue has already been fixed in the latest 2026v1 Hotfix 1 release. Upgrading the C1 Blazor packages in your project to this version will resolve the problem.

  Regards,
