Make Map Layers More Interactive with Tooltips
In this article, we will explore how to make map layers more interactive with tooltips using Essential JS 2 and Blazor Maps. Tooltips are a great way to provide additional information to users when they interact with different map elements.
Getting Started with Essential JS 2 and Blazor Maps
First, we need to include the Essential JS 2 and Blazor Maps libraries in our project. These libraries will allow us to create interactive map layers with tooltips.

var map = new ej.maps.Maps({

properties: {

},
geometry: {
type: "Polygon",
coordinates: [[[-74.0060, 40.7128],[-73.9776, 40.7500],[-74.2591, 40.6977]]]
}
}
]
},
tooltipSettings: {
visible: true,
valuePath: "name"
}
}
]
});
map.appendTo('#maps');

Blazor Code
@page "/maps"
<EjsMaps id="maps">
<MapLayers>
<MapLayer>
<ShapeLayer>
<ShapeData>
@{
List<object> shapes = new List<object>();
shapes.Add(new
{
type = "FeatureCollection",
features = new object[] {
new {
type = "Feature",
properties = new {
name = "New York"
},
geometry = new {
type = "Polygon",
coordinates = new double[][] {
new double[] { -74.0060, 40.7128},
new double[] { -73.9776, 40.7500},
new double[] { -74.2591, 40.6977}
}
}
}
}
});
shapes
}
</ShapeData>
<TooltipSettings>
<TooltipSettings>
visible = true,
valuePath = "name"
</TooltipSettings>
</TooltipSettings>
</ShapeLayer>
</MapLayer>
</MapLayers>
</EjsMaps>
Conclusion
By using tooltips in Essential JS 2 and Blazor Maps, you can make your map layers more interactive and provide valuable information to users. Experiment with different tooltip settings to customize the appearance and behavior of tooltips in your maps.
