[ZS0] Re: [mapguide-users] [ZS0] drawing customized markers on the fly

[Kenneth, GEOGRAF A/S]

I understood from your original post that you wanted a tooltip with 
different icons.
If that is the case, you can just modify the tooltip.

If you want different symbols displayed in the map, you must create a 
theme (or display rules) in the layer.
The easiest way to accomplish this, is to create an extra column, say 
"symboltype".
The modify the layer to show different symbols based on the "symboltype" 
column.

I would recomend that you create a featuresource with sample data, and 
the create the layer in Studio.
Once you have the layer, you can copy it to the session repo, and modify 
the FeatureSource property to point to the temp source.
Alternatively, you can save it to an Xml file, and use the approach 
outlined in the buffer example.
