Hi Paul,

You requirement is click on map, then did spatial query based on the clicked coordinate and shows information about it.

Here is a sample collection for our Blazor version: https://github.com/ThinkGeo/HowDoISample-ForBlazor

I think you can view it and find how to implement, for example you can know how to handle click event and do spatial query based on it from this sample: Find nearby places

I hope that’s helpful.

Regards,

Ethan
