Object model for scripting in Report Designer

I'd like to do more with the scripting in the Report designer.

 

I noticed that the example for the resizable legend template uses the scripting: http://support.geocortex.com/resizeable-legend, but I'm running into a brick wall as to figuring out how to code beyond that example. Is there object model that I can look at or something that tells me how one uses the scripting?

Specifically, I'd like to figure out a way to change the grid that gets displayed over a map. Currently, the Lat/Long units are displayed in Deg-min-sec and I want to show it in the format of Decimal-Degees.

  This is what I figured out so far:

  1. Every Gecortex report is an ActiveReport document and can be opened/edited with Visual Studio
  2. The Gecortex Map control within a given report is a type of ActiveReport ARControl, as defined in the XML structure:

   <Sections>

       <Section Type="Detail" Name="detail" >

            <Control Type="AR.Image" Name="_MainMap" DataField="_MainMap" BackColor="4163021"  />

    3. One can gain access the control through the scripting code (see below), but I'm not sure how to go from a ARControl to a Gecortex-Map-Control and subsequently make any modifications to it (like simply changing the background color):

   

  public void ActiveReport_ReportStart()

   

      {

   

     // Define the color red - this works fine

   

     System.Drawing.Color clr = System.Drawing.Color.Red;

   

    

   

     //Make reference to the "MainMap" object - this works fine

   

     DataDynamics.ActiveReports.ARControl Map = rpt.Sections["detail"].Controls["_MainMap"];

   

    

   

     //Change the Background color to red - this crashes

   

     Map.BackColor = clr; 

   

    }

   

  As I learn more, I'll add to my thread. But, at some point it would be helpful to guidance as to how others have done this.

  Update: I figured out that the Map control is a DataDynamics.ActiveReports.Picture object. That class does not provide much additional properties that address my particular needs.

  I think I understand it. The map control is bound to the _MainMap field(???) of the MapSubReport (which is a type of DataTable). I suspect that when one runs a print operation, Geocortex Essentials creates the map graphic (Png, jpg, or other), followed by creating and populating the DataTable, followed by loading the report template.

  If this is valid, I believe my answer lies in how the graphic is generated from within Geocortex Essentials versus how the graphic is integrated within the report.
