About this sample
This GeoBlazor sample, written in Blazor for .NET developers, demonstrates capturing map click events, drawing dynamic Graphics, and triggering custom popup actions using the OnClick event of GeoBlazor's MapView Razor component, which wraps the ArcGIS Maps SDK for JavaScript MapView and Graphic APIs. The page shows a low-zoom 2D world map drawn with the World Ocean basemap (a TileLayer loaded from an ArcGIS Online portal item). Clicking anywhere on the map runs a HitTest to detect existing graphics; if no graphic was hit, a yellow SimpleMarkerSymbol with a blue outline is added to a GraphicsLayer at the clicked location. The graphic carries a PopupTemplate that displays the longitude and latitude and exposes a custom ActionButton (Click to Add to List, decorated with the dymaptic logo); clicking the action appends the point's coordinates to a Points Clicked list rendered below the map. The sample is intended to demonstrate event-driven graphic creation and popup actions in a Blazor application without writing JavaScript.
