Perform an identidy

Selecting data on the map.

To perform selection on a map you need know how the service layers are named and what fields they provide.
There is a tool available (When you installed the map extention) under the menu Window->Other panels->Arc IMS services.
This tool can help you explore the map service. Before you can perform a selection you need to know 2 things.

1) The layerid you want to make the selection on. The ArcIMS service tool will display this information between [ ].
2) The field-names you would like to retrieve.

Once you know what information you want the user to see. Do the following action on your map-viewer.

1) Drag an selectLayer component on the stage.

2) Open the properties window (Or use Alt-F7) to see all properties as shown below.

3) find the "fromlayer" property and refer to the layerid your selection should be performed on. In this example the layerid is called "SDEEPER_points"
4) Double click on the "subfields" property and add all fields you like to retrieve. (this is optional) In this example we use the #ALL# tag.
5) Type the map_instance name inside the "target_instance_name" property. In this example we use "my_map"
6) Depending on the type of layer (line,point,poly) you can decide how you would like to display the selection on the map. in this case it is a point layer and we show the selection with a marker symbol. Double click on the "Marker symbol" property.
7) Press the + sign.

8) Alter the symbology as you wish and press Ok.

9) Now we need to decide where the result will be send too. Drag a grid-component on the stage and call the grid "my_grid" in the instance name of the component.
10) Go back to the selectionLayer component and type "my_grid" inside the result_instance_name property.

You can drag multiple of those selection-components on the stage and point them to different output objects. Also the onSelectResult of the map-component will trigger each time a selection is performed. Other action could be taken from this event.

At this moment the map is ready for selection. A selection will only happen when the user interaction is set towards "select" mode. In this example we simple drag the select-button on the stage and refere to my_map. The result shoud look like this.
