Set document properties from marked records

from Spotfire.Dxp.Data import DataValueCursor

myLatCursor = DataValueCursor.CreateFormatted(Document.Data.Tables["mydatatable"].Columns["latitude"])
myLongCursor = DataValueCursor.CreateFormatted(Document.Data.Tables["mydatatable"].Columns["longitude"])

markedRows = Document.Data.Markings["Marking"].GetSelection(Document.Data.Tables["mydatatable"]).AsIndexSet()
for row in Document.Data.Tables["mydatatable"].GetRows(markedRows, myLatCursor):
 Document.Properties['refLat'] = myLatCursor.CurrentValue

for row in Document.Data.Tables["mydatatable"].GetRows(markedRows, myLongCursor):
 Document.Properties['refLong'] = myLongCursor.CurrentValue

This script can be used to set 1 or more document properties from a marked record. If more than one are marked, it uses the last one in the stack. The example above sets the "refLat" and "refLong" properties from the "mydatatable" datatable, which has Latitude and Longitude columns. This script was used in the "Visualizing the radius around a point on a map" article as seen on the Tips & Tricks blog.
