GeoBlazor 4.4 - A Holiday Gift for Your Maps!

View Updated Samples | Full Release Notes

🛡️ Enhanced Exception Handling

Take control of how your application responds to runtime errors with new exception handling capabilities:

• OnExceptionHandler – New callback on both MapView and AuthenticationManager lets you intercept JavaScript errors. Return true to handle the exception gracefully, or false to re-throw.
• Better Authentication Errors – The AuthenticationManager now surfaces JavaScript errors during initialization so you can respond appropriately.

📚 Bookmarks Widget Gets Smarter

The BookmarksViewModel now includes two new event handlers for greater control:

• OnBookmarkEdit – Fires when a user edits a bookmark
• OnBookmarkSelect – Fires when a user selects a bookmark

These events give you full access to the Bookmark object for custom handling.

📐 Measurement Widget Improvements

Both AreaMeasurement2DWidget and DistanceMeasurement2DWidget now include a ViewModelChanged callback, allowing you to respond to property changes on the underlying ViewModel in real-time.

🌍 RTL Language Support

New OverlayPosition enum values provide support for right-to-left languages:

• TopLeading
• TopTrailing
• BottomLeading
• BottomTrailing

🐞 Bug Fixes

• Fixed SearchWidget event results not returning correctly
• Fixed FeatureLayer.ApplyEdits not throwing exceptions on failure
• Fixed registration of ArcGIS-loaded objects like Sublayer

📦 API Cleanup - Out with the Old!

This release consolidates several types and removes unused classes to keep the API lean and maintainable:

• Unified ElevationInfo – All layer elevation info types consolidated into a single ElevationInfo class
• Namespace reorganization – GeoLocationOptions moved to dymaptic.GeoBlazor.Core.Options; InitialViewProperties and related classes moved to dymaptic.GeoBlazor.Core.Model
• Removed placeholder classes – Unused classes like Weather, Lighting, and Slide have been removed and will return when fully implemented
