This is my very first question, so please forgive me if i'm not using best practice... here is my question:
I have an web app where people can draw polygons over a basemap (html based), the polygons are then stored in my sql server database as a WKT string ("MULTIPOLYGON(((lat long, lat long, lat long, ...)),((lat long, lat long, lat long, ...)), ...)").
Which means one multipolygon string has many sub-polygons which display as different shapes on the screen when the page re-loads.
Is there a way to click on one shape and identify which sub-polygon is being clicked (the goal is to be able to delete it from sql if shape was incorrectly done)?
e.g. the bold string below, being sub-polygon number 2 of the multipolygon (also shown on the image i attached):
MULTIPOLYGON (((-74.4897049011512 40.802801297423777, -74.489796096257678 40.802841904076779, -74.489778661899081 40.802862207393964, -74.489690149001618 40.80282160075339, -74.4897049011512 40.802801297423777)), ((-74.489702550924846 40.802796180105481, -74.489713279760892 40.8027789222691, -74.489821909225967 40.802829680598578, -74.4898071570764 40.802835771595511, -74.489702550924846 40.802796180105481)))
I was thinking something like getting the coordinates of the click and check if it falls inside any of the sub-polygon, but i am having a hard time trying to do it, and was wondering if ArcGis API had already something existing.
