How to zoom to a selected point from xyEventSource file?

LazarKovacevic

I made a code whitch work for features if i convert xyEventSource file to shape file but I need to zoom selected features if its in xyEventSource.
Im working in C#.

I fiiled checkedBox with rows of xyEventSource file but i cant zoom to checked item. if it s converted to a shape file i can zoom to checked item but i cant do that if its not converted to a shape file, and thats is the point. Can someone help me, pls?

p.s. Sorry for my bad english.

Hi,
If you added an event table to ArcMap then right clicked over it and selected �??Display Route Events�?�, a layer should be added to ArcMap that behaves much the same way as other featureclasses. You should then have access to feature extents for zooming. If I understand your question, you populated a list with values from the xy event table. From there you would need to identify the layer created by doing the �??Display Route Events�?� then query that layer for the needed feature. I added code for a console app that shows one way to get to features built from an event source.
