Get Coded Value Domain Activity

Description:

Gets the coded value domain values for a field on a layer.

Inheritance Hierarchy:

System.Object
  System.Activities.Activity
    System.Activities.NativeActivity
      Geocortex.Workflow.Activities.GetCodedValueDomain

Function:

This activity performs an HTTP request to an ArcGIS Server layer to obtain an IDictionary<object,string> result that contains the specified field's coded value domain information. The dictionary keys represent the codes, and the dictionary values represent the textual names.

In a Workflow:

You would use this activity to obtain the coded value domain information for a field. You could then use the ListToDataItemList activity to transform the domain values into an IEnumerable<DataItem> that could be passed to a DisplayForm activity and used to populate a ComboBox or ListBox form item.

You can optionally use the Feature Type Name argument to restrict results to a particular feature type.
