I believe you can refresh without a full reload of the map. How it behaves may also depend on other layers that also have labels that may be displaced as the new labels are recalculated.
I'm not 100% sure how you update the layer definition in the session other than update the layer_name resource that has the session appended to it in the session repository. You can probably find an example in other mailings or the dev guide on how to do that.

Can this be done without reloading the map?

You could implement a +/- on the toolbar which updates the layer definition to change the size by some fixed increment. Not sure if this is the best way, but it is one way. Regards, Dave From: [email protected] [mailto:[email protected]] On Behalf Of Jonathan Rizzo Sent: Tuesday, November 02, 2010 12:41 PM To: [email protected] Subject: [mapguide-users] Dynamic label size Hello, I am getting back in to MapGuide development after an extended hiatus. I am trying to make changes to an application that I developed a long time ago, and I'm not exactly sure how to accomplish what I am trying to do. I would like to allow the user to manipulate the size of a layer's labels. Ideally, I would like to put a + and - icon on the toolbar which resizes the labels up or down by some fixed amount. Is this possible? Can anybody point me to an existing sample or bit of code that that shows how this would be done? Any assistance that you can offer would be greatly appreciated. Thanks!
