https://community.esri.com/t5/arcgis-pro-ideas/allow-a-definition-expression-to-be-added-to-a-map/idi-p/922766 <P><SPAN>Lets say I have a Map Service, published using ArcGIS Server, of the US State Boundaries. I can add this Map Service as a Layer to ArcMap and I see all of the US State Boundary features. Now I need to restrict which states I can see by adding a where clause or definition expression, something like NAME = 'OHIO'. Right now this is not possible using ArcMap 9.3.1 and ArcGIS Server 9.3.1.<BR /><BR />This is possble using the ArcGIS Flex API, REST, and the ArcGISDynamicMapServiceLayer (and its layerDefinitions property) we are able to dynamicaly add layers to our Flex application and only show a subset of features by using a where clause. Plus the server does all the heavy lifting of building the image for that layer. I need to do the same thing using ArcMap insdead of Flex.<BR /><BR />I believe this is a gap in the capability of ArcMap and ArcGIS Server vs. Flex and ArcGIS Server. This can be done using a web browser with Flex and REST but not with ArcObjects and ArcMap. If this enhancment is made it should also work in ArcGIS Explorer too.<BR /><BR /></SPAN></P> Tue, 13 Aug 2024 13:37:20 GMT EricPaitz 2024-08-13T13:37:20Z https://community.esri.com/t5/arcgis-pro-ideas/allow-a-definition-expression-to-be-added-to-a-map/idi-p/922766 <P><SPAN>Lets say I have a Map Service, published using ArcGIS Server, of the US State Boundaries.
