newbie: buffer/tolerance around click point

Question

Hi

its my first time using the ESRI silverlight control, so I'm not sure of the best way to achieve this...

I have loaded in some map data from a JSON feed. This is then used to display points on the map.

when the user clicks on one of those points I need a dialog box to open.

I am unsure of how - and what classes to use - to create a rectangle or area around the clicked pixel, and then iterate through the collection (from JSON) to see if the clicked area contains an item from the JSON collection.

Is there an example of this, or can someone help me out?

Regards,

The tolerance property of the IdentifyParameters class is how to handle this. Thanks for the help.

Would this be possible on an ArcGISDynamicServiceLayer for an Identify Task? I'm just asking because our Map_MouseClick event makes the user click on the exact pixel to get a Identify completed on a Point feature, and it makes it difficult for the end user to select an item.
