MapTool that selects only one feature

How to create a map tool that selects only one feature when click on a point with a tolerance.

For now I can use ActiveMapView.SelectFeatures(geometry), but this method can select multiple feature layer or multiple feature in a layer.

var selection = ActiveMapView.SelectFeatures(clickedPoint, method: SelectionCombinationMethod.New);

You most likely want FeatureLayer Select(...). https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic11392.html

Something like:

var sqf = new SpatialQueryFilter() { FilterGeometry = clickedPoint, SpatialRelationship = SpatialRelationship.Intersects,//change as needed WhereClause = "Optional SQL whereclause here", SubFields = "*" }; var selection = featLayer.Select(sqf);

What about this:

var features = mapView.GetFeatures(point); if (features.ContainsKey(layer)) { var tag = features.FirstOrDefault(t => t.Key == layer); var oids = tag.Value; foreach (var oid in oids) { oids = oid; } var filter = new QueryFilter { WhereClause = " OBJECTID = " + oid }; var select = layer.Select(filter);

I don't know what you mean by

// this statment oids = oid;

However I was able to get the answer from the method you have mentioned GetFeatures(geometry).

Thank you for your help.
