SyncMarkersbuilds a payload array that the clustering path discards.Lines 861-872 run
ToMarkerPayloadfor every marker and fillids/payload. WhenIsClusteringis true,PushClusteredMarkersAsyncrebuilds both arrays from_markerState, so the first pass is wasted. Clustering is the mode used with large marker counts, andApplyMarkersAsyncroutes its batched replace through this method.Move the clustering branch above the payload loop and keep the per-marker null check and

In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/BitMap.razor.cs`:
- Around line 1254-1261: Update OnClusterClick so BitMapClusterClickArgs.Count
is populated independently of Clustering.ZoomOnClick by retrieving the cluster
marker count unconditionally from the clustering layer; preserve the existing
zoom/expand behavior as conditional on ZoomOnClick and keep interop error
handling intact.
- Around line 726-734: Ensure popup reconciliation occurs on every marker-state
commit: in src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/BitMap.razor.cs lines
726-734, update RemoveMarker to call ClosePopup when _openPopupMarker?.Id
matches markerId before returning; at lines 751-757, update the ClearMarkers
clustering branch to call ClosePopup before returning; at lines 1666-1670,
update ApplyMarkersAsync to call ReconcileOpenPopupAsync(openId) after
SyncMarkers and before returning.
- Around line 459-462: Remove the insertion-order guarantees from the
documentation for MarkerIds, LayerIds, TileOverlayIds, OrderedMarkers, and
MarkerListTemplate, since the underlying dictionaries do not preserve that order
after removals. Update the related BitMap.razor marker-table documentation as
well, without changing the existing dictionary-backed behavior.
- Around line 1549-1550: Update PushCameraParametersAsync so a missing Center
and _lastView does not return before applying a configured Zoom. Preserve the
existing center-based camera update when a center is available, while allowing
the zoom-only binding path to send Zoom during the initial OnAfterRenderAsync
application.
- Around line 579-584: Update SetZoom to obtain the fallback view through the
same SafeInvokeAsync and OnInteropError handling used by SetView, FlyTo, ZoomBy,
and PanBy, so GetView failures are surfaced through OnInteropError instead of
propagating JSException; preserve use of _lastView.Center when available.
- Around line 1841-1845: Update SwapProviderAsync so a successful provider swap
invalidates the existing marker reconciliation snapshot before reapplying the
declarative Markers set. Clear or reset _markerState before the next
ApplyMarkersAsync call, while preserving the existing clustering and optional
imperative-state replay behavior, so all current markers are sent to the new JS
instance.
- Around line 2053-2060: Move the marker-list XML summary so it documents
NotifyMarkerListChanged, and keep the close-button summary directly attached to
ClosePopupFromUi. Ensure each method has exactly one correctly positioned
summary so generated XML documentation indexes both members accurately.
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/BitMapChrome.ts`:
- Line 371: Update the Escape-handling logic around s.canvas.blur() to blur
document.activeElement when it is an HTMLElement contained within s.root, so
focused descendants exit the map interaction region; retain the existing guarded
behavior for cases without a qualifying active element.
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/BitMapCluster.ts`:
- Around line 113-115: Update the render signature in the map cluster render
flow to include each cluster’s member count and centroid alongside marker IDs,
ensuring membership or centroid changes invalidate the early-return check and
re-sync the provider bubble. Preserve the existing lastSignature comparison and
assignment behavior.
In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/BitMapJsRuntimeExtensions.cs`:
- Around line 177-180: Update BitMapChromeWaitForVisible to call the
CancellationToken overload of InvokeVoid and pass CancellationToken.None,
avoiding the default interop timeout while preserving the browser-side wait
behavior.
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/IBitMapProvider.cs`:
- Line 48: Replace the boolean RequiresWebGl capability in IBitMapProvider with
a required WebGL version, set the Mapbox provider’s requirement to WebGL2, and
update BitMapChrome.hasWebGl plus BitMap<TMapProvider> capability checks to
compare the detected context version against that requirement so unsupported
environments show the unsupported state.
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/Providers/BitMapArcGis.ts`:
- Line 844: Update the view.when() rollback path to remove
__bmContextMenuHandler before calling view.destroy(), matching the cleanup
performed by dispose. Preserve the existing double-click and keyboard handler
cleanup and retry behavior.
In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/Providers/BitMapAzureMaps.ts`:
- Line 228: Update the existing-marker cleanup block in the marker replacement
flow to remove existing.tooltip before assigning the new entry to
s.markers[markerId]. Preserve the current cleanup of the old popup and marker,
ensuring no stale tooltip or popup remains when a marker is replaced.
- Around line 233-234: Update the show callback to read the marker’s current
position via marker.getOptions().position when opening the tooltip, instead of
using the initially captured position, while preserving the existing tooltip
options and error handling.
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/Providers/BitMapCesium.ts`:
- Around line 770-772: Update the marker click handling near the s._drag check
to use a one-shot suppression flag set when a drag ends, because s._drag is
cleared before Cesium emits the synthesized LEFT_CLICK. Consume and clear the
flag in the click handler so that only the trailing drag-generated click is
ignored, while genuine subsequent clicks still invoke OnMarkerClick.
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Map/Providers/BitMapGlBase.ts`:
- Line 287: Update BitMapGlBase.panBy so essential: true is included in the
panBy options object alongside duration, and remove it from the separate
eventData argument; preserve the existing animate-dependent duration.
In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Extras/Map/BitMapDemo.razor.cs`:
- Around line 1235-1244: Update the labels BitMapTileOverlay in OnLayersReady to
reuse the distinct labels tile source from Example 7 instead of the default
OpenStreetMap URL; remove the Subdomains setting unless the replacement
UrlTemplate contains {s}. Keep the existing overlay identity and display
settings unchanged.
In `@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/Map/BitMapTests.cs`:
- Around line 2359-2369: Update ViewPayload to construct its interpolated JSON
using FormattableString.Invariant so double serialization remains valid under
comma-decimal cultures. In the marker table assertion, replace the hardcoded
"50.45000" value with 50.45.ToString("F5"), preserving the component’s
current-culture formatting.
