I was trying to figure out how to use dynamic text from an attribute table in a collection of Data Driven Pages in ArcGIS 10.
I've looked in the help files, but can't find anything on dynamic text from attribute tables.
The only attribute table accessible through Dynamic Text is the attribute table of your Data Driven Pages index layer. I'm assuming your Data Driven Pages map book is based off of your grid layer, and if so then you're in luck.
Using a dyn tag of type 'page', you can access any property of the index layer
For example, to grab the 'GridName' of the current page, use:
You have probably looked at Using Dynamic Text with Data Driven Pages in the ArcGIS help files, but you may have missed the 'Tip:' section near the end of the page that explains this.
Labels from attribute tables are dynamic.
You can do a few things before you run date driven pages export
Create an index grid
Calculate adjacent fields
This will give you dynamic A1,A2,A3 bingo grid generation...
