If I know the lat/long, how can I zoom to that location? Let's say I want to zoom to -80.3862,25.9029 on center, with a 50-foot buffer. I tried the following code:

RectangleR newExtent = new RectangleR(new PointR(x1, y1), new PointR(x2, y2));
Map1.CurrentExtent = USARenderers.GetExtent(13, newExtent);

 

However, that seems to put me off into the ocean somwhere. Any advice?

 

 

We don't know the values of x1, y1, x2 and y2. We would need to know those values and how you get them.
Thank you.

Thank you for your reply, but if you read my initial post clearly, you would have learned that I described what the x1, y1, x2 and y2 coordinates should be:

-80.3862,25.9029 on center, with a 50-foot buffer

I only included the code to illustrate how I am setting it now, by updating the CurrentExtent on the map (which does not work).

If you want to get an extent from a point at location -80.3862, 25.9029 with a 50 foot buffer, try the following code:

MapSuite.Geometry.Ellipse Ellipse = new MapSuite.Geometry.Ellipse(new PointShape(-80.3862, 25.9029), 50, Map1.MapUnit, MapLengthUnits.feet);
Map1.CurrentExtent = Ellipse.Envelope.ToRectangleR();

Thanks! Your solution was "almost" perfect. I only had to add the following to get it to work with RenderUSA:

Map1.CurrentExtent = USARenderers.GetExtent(13, Ellipse.Envelope.ToRectangleR());
