How to convert X/Y to lat/long

[ShaningYu]

For a MapPoint, I get its X/Y coordinate values.  How can it be converted into lat/long values?  Thanks.

Shaning,

It depends what coordinate system your application is in. If you are using web Mercator there is a class, see here:

If you are using anything else you will have to do the math yourself or use your geometry service.

If you are just looking to convert coordinates as a widget, I made one a little while ago.
You can download it here:

If anything you can dig through it and use it as a code sample.

IF you already have it in ArcMap simply create a new x,y fields (lat long)  and use the right click on one of the new columns and select Calculate Geometry.

If you don't have it in ArcMap use the X,Y to create the features and then do the above.

Using the CoordinateMenu component and revising a couple of functions, I made conversion very well.  Thanks.

Call a simple function:

myMP=map.toMapFromStage(X,Y);
