What is the best way to select a group of points on a map? I would like to use the mouse to draw a box around them similar to Microsoft Paint. Once selected the points would change to another color to show that they are selected. It seems that if I hold down the Ctrl+Shift keys, click the mouse and drag it I do get a box but then the map zooms out. My application is a .Net app using WPF. I am using the 100.1 version of Esri ArcGIS.
You can use the MapView.SketchEditor to draw a box, then use the box drawn to perform a spatial query, and select whichever features came back from the query.
