Hi All,

I am trying put the attribute result of a Geoprocessor activitity (from a GPFeatureRecordSetLayer) into a Workflow Form. But I am lost in the steps I need to undertake to do this. I have played around with the "Collect external event Args" and the "List to data item List" activities. but I really don't know how to fill in all the fields right.

Below is shown (partially) the output parameter from the GP service. In details I want to map the Fields "Name", "SourceID" & "Total_minutes" to the Workflow form.

Can anyone help me out?

- Sune

Parameter: Closest_Resources

Data Type: GPFeatureRecordSetLayer

 

Display Name: Closest Resources

 

Direction: esriGPParameterDirectionOutput

 

Default Value:

Geometry Type: esriGeometryPoint

 

Spatial Reference: 25832

 

Fields:

 

ObjectID (Type: esriFieldTypeOID, Alias: ObjectID)

 

Shape (Type: esriFieldTypeGeometry, Alias: Shape)

 

Name (Type: esriFieldTypeString, Alias: Name)

 

SourceID (Type: esriFieldTypeInteger, Alias: SourceID)

 

FacilityRank)

 

...

Total_Minutes (Type: esriFieldTypeDouble, Alias: Total_Minutes)

  Hi Sune,

  I can see what you are attempting to accomplish.

  Did Ryan Cooney’s post on our User Forum help you with this? I think his suggestion is a good start…

  You will need to:

  1. Get the “FeatureSet” object from the GPFeatureRecordSetLayer
     • Consult the Silverlight API reference at http://help.arcgis.com/en/webapi/silverlight/apiref/. You are looking for:

        

       ESRI.ArcGIS.Client.Tasks >> GPFeatureRecordSetLayer >> Members
  2. Use the ForEach<T> activity to loop through each item in the FeatureSet.Features collection.
     • FeatureSet.Features is an IList<Graphic> collection, so each item will be of type ESRI.ArGIS.Client.Graphic
  3. For each graphic, you can get the values of the Name, SourceID, and Total_minutes attributes by accessing the “Attributes” collection. In VB syntax, getting the value of an individual attribute will be something like:

      

      

     myGraphic.Attributes.Item(“Total_minutes”)

      

      
  4. Put these values into a new Geocortex.Forms.Client.DataItem object. A list of these DataItem objects can be used to populate a drop-down in a form.

   

  I hope this helps!
