Search with Multiple Sources

This GeoBlazor sample, written in Blazor for .NET developers, demonstrates the Search widget configured with multiple custom sources from the ArcGIS Maps SDK for JavaScript exposed through GeoBlazor's SearchWidget, LayerSearchSource, and LocatorSearchSource Razor components. The page shows a 2D dark-gray basemap of the contiguous United States. In the upper-right corner of the map sits a Search widget whose source dropdown lets the user choose between Congressional Districts (a FeatureLayer keyed by DISTRICTID), Senators (a FeatureLayer keyed by Name or Party with a custom suggestion template and a senate icon picture marker symbol), the ArcGIS World Geocoding Service, or all three at once with the placeholder Senator or World Location Service. Selecting a result zooms the map and opens a PopupTemplate appropriate to that source. The default sources are disabled so only the configured ones appear. The sample is intended to demonstrate combining feature-layer search and a world geocoder behind a single search widget in a Blazor application without writing JavaScript.
