Joe,

Don't think this is as much a binding issue, as it is that you're trying to plug into framework code, so you need to do it the "framework way."

If you look at the framework event handler code you're trying to use, it eventually looks for a datarow from which to gather the primary key value you need for your method -- that's how e.PrimaryKeyValue gets populated.

Check out CallStateChange method again... it has a few overloads, of which one has the following signature:

CallStateChange(mmBusinessState bizState, string tableName, DataRow dr)

dr can be any datarow that contains the same primary key column (with the same field name) as oCompanyList.PrimaryKey property and PK value you want passed to the statechange handler.

Hope that makes sense,
---J
