Buffer around a point with button

Question

Hi, I'm trying to create a buffer around a school and i only want the buffer to come out when i click a button from the pop up menu of the school, I already have the pop up menu and the map, what i need is to know how to capture the x,y coordinates of the school and how to subsequently draw a buffer around the school. Any ideas?

I am using a graphicLayer for my school and it is initialized with a button but how do I carry on and draw a buffer?

p.s. sorry I'm quite lost, I'm new to this

I was supposing that you were using a GraphicsLayer or FeatureLayer to display your school.
 
Is it the case?
 
If it's the case, the graphic variable have to be initialized with the graphic of your school (either by an user interaction such as a click or by code filtering the graphics of your graphicslayer by attribute).

Also when I enter this into my codes, I keep getting an error that says "the name graphic does not exist in the current context"

string axisX = (graphic.Geometry as MapPoint).X;
string axisY = (graphic.Geometry as MapPoint).Y;
