IdentifyTask not working on touch enabled devices

BobNichols

Ran into a problem today when viewing my Silverlight App on a laptop that had a touch screen.  Everything works except when trying to "Click" or tap on a property to identify it.  The identify task doesnt run unless I grab the mouse and click.  Screen taps appear to not work.  I wanted to see if it was my app or not so I viewed the live samples on this site and sure enough it doesnt work there either.  Is this a limitation of Silverlight or is there a different click event that needs to be run when a user taps the screen rather than click?  I tried searching this site and using the google but came up with nothing.  Thanks!

The identify task doesnt run unless I grab the mouse and click.  Screen taps appear to not work.

It's depending on the event you subscribe to execute your identify task.
If you subscribe to MouseClick event only, the identify task won't run on Tap event.

You have to subscribe to tap or, better, MapGesture event as well.

Another approach consists to use a Draw object in Point DrawMode and to execute the identify task when the draw completed.
The Draw object includes snapping capabilities so this approach is recommended.

I wanted to see if it was my app or not so I viewed the live samples on this site and sure enough it doesnt work there either.

You are right. We are considering to enhance the samples to get a better support of the touch screens.
