Linking objects to a data source
The following example shows a world cup poll with five possible choices. Note that Portugal
and Switzerland both have the same number of votes.
While the R ANK column indicates that Portugal and Switzerland are tied for 3rd place, in the
U NIQUE R ANK column Portugal is ranked before Switzerland based on alphabetical ordering.
The T IE C OUNT is 1 where there is no tie, but is 2 for Portugal and Switzerland who are in a
two-way tie.
Creating a template that retrieves social media content
After defining data sources, snapshots and tickers, the social media content can be used in
a template. In template logic, a single item of data is specified using a data descriptor. This
data descriptor can be used in the property of a control or in the parameter of an Action or
Event.
Figure 9-31 demonstrates that the D ATA S OURCE property of the text box is set to the data
descriptor for the cell that was dragged out of the table:
Data:SocialMedia:Ticker(UserName, 1)
