This sample demonstrates how to join the map to a database in order to present
values from the database on the map as a colored-gradient value theme. This
join operation is to a SQLite, but the sample is also applicable to joining to
other SQL server database products. This sample is a replica of the DK.NET
JoinAndRender sample which is found in the DK Sample Set #4. The ASP.NET
source code for this sample is provided below.
From the drop down menu, select either the ‘forest’ or ‘agriculture’ option.
The selection of ‘forest’ color renders each polygon area based on values from
the database representing the land areas used for forestry purposes.
The ‘agriculture’ selection color renders each polygon to reflect the land
areas used for agricultural purposes.
