Check boxes to toggle layer visibility

I need a simple workflow that presents the user with a list of checkboxes that will toggle individual layer visibility for certain layers on the map. Does anyone have an example workflow that does this or something similar? Thanks in advance :)

  Rebecaca,

   

  there are various ways. Here is what I would like to implement.

   

  1) Log on the Geocotex Essential Manager, edit Site,

   

  2) Edit a layer, and Add a Property whose name as 'DynamicVisibilityLayer' something similiar you want to call, and set value 'true' or something similar.

   

  3) repeat step 2 as many as layer you want to choose for the list of layers you want to use in the Form later with the checkboxes. Step 1 to 3 will modify your Site.xml where <Property Name='DynamicVisibilityLayer' Value='true'/> to all layers you set up on step 2 and 3 when you see the Site.xml

   

  4) Create a new workflow

   

  4-1) Add 'Get Layer Info By Property' activity and set PropertyName argument as 'DynamicVisibilityLayer' which you choose on Step2 above, and which activity returns 'Layers Info List with EssentialLayerInfo data type.

   

  4-2) Loop through the result of step 4-1 and built your dataItem for the checkbox for the Form. The dataItem value will be 'MapServiceId' and 'Id' from 'EssentialsLayerInfo' and DisplayName will be 'Name'. NOTE Step 4-1 and 4-2 can be done various ways such as (1) hardcoded list of DataItem, or use 'GetLayerList Item Info' activity  or this example etc

   

  4-3) Add DisplayForm, where add CheckBox whose input will be from step 4-2, and add button

   

  4-4) Final activity you need to use 'SetLayerVisibility' which requires 'MapServiceId' or one of LayerId or LayerName, and Visibile. All previous steps are to get 'MapServiceId' and LayerId/Name to set visibility. So you may need to parse the selected Checkbox object to get MapServiceId and LayerId with any Delimiter you might introduced on step 4-2.

   

  This pesudo implemenation is assumed you want to use only workflow and Site configuration.

   

  Wish this to give your start point and the idea how to approach.
