Changelog for DocuVieware

RSS

3.4.5 25 Jun 2026

  • Added
    Adds an asynchronous handler overload for custom toolbar buttons in the DocuVieware Blazor component.
  • Fixed
    Fixes an issue where custom toolbar buttons created with AddCustomToolbarButton rendered with the wrong icon size and color in the legacy theme and weren’t added when the control ID wasn’t the default.
  • Fixed
    Fixes an issue where DocuVieware Blazor server actions hung under concurrent calls by surfacing a retryable pending status.
  • Changed
    Benefits from underlying changes from Nutrient .NET SDK.

3.4.4 12 Jun 2026

  • Added
    Adds the ReloadDocument method to the DocuVieware Blazor wrapper to repaint the currently loaded document, which is useful after reconnecting to an existing session.
  • Added
    Adds the UnselectAnnot and UnselectAllAnnotations methods to the Blazor wrapper.
  • Changed
    Improves the reliability of server-side custom actions in the Blazor wrapper by dispatching PostCustomServerAction callbacks per session and preventing a handler leak that could occur when a Blazor circuit disconnected mid-action.
  • Fixed
    Fixes an issue where IsInitialized() and IsLoaded() in the Blazor wrapper threw a NullReferenceException when called before the control was ready. Both methods now return Task<bool> so the result can be read.
  • Fixed
    Fixes an issue where the DocuVieware Blazor viewer was blanked when the host application triggered a render during viewer initialization.
  • Fixed
    Fixes an issue where UpdateAnnotById in the Blazor wrapper invoked the wrong server method. Editing an annotation by its identifier now updates the annotation as intended.
