I have this by reading the API of this link:
FindIndex / FindLine
- FindIndex pKey, pSearchString
- Search for data in pKey that matches pSearchString. pKey is one of
the custom defined keys you defined for your data. pSearchingString is
the value to look for in that key. You can pass multiple
pKey=pSearchString combinations to match multiple criteria.
-- Find the index where "message" is "hi"
dispatch "FindIndex" to group "DataGrid" with "message", "hi"
put the result into theIndex

Anyway, there is only a few function in the datagrid API.
You have also:
- ColumnControlOfLine a recent function added with the datagrid
library version 1.0.2 build 6
- GetKeyValuesOfIndexes used by the dgKeyValuesOfHilitedIndexes
property. I think it is recent and I have not explored it yet.
Some properties, functions or commands are indeed not documented in the API.
In my experience, be extremly carefull before to conclude your
datagrid is broken. It could depend how you explored the parent
script. If you opened the library script by using such command as "go
to stack revdatagridlibrary" and then editing the datagrid button, the
library could stop working properly resulting of odds effects in your
opened datagrids. In this case, close your copy of LC and reopen it.
Then, test your work again.
For a safe parent script exploration, prefer to edit the parent script using:
edit script of btn "data grid" of stack revdatagridlibrary
