Maintenance Form Tool Strip Greyed Except for New

GGP — Sat, 04 Apr 2009 13:04:34 GMT

I'm a newbie user and I've created a Maintenance Form with a Business Object and I put in 6 textbox fields the same way the demo shows. When the form appears, all of the buttons on the MaintenanceFormToolStrip are greyed out except I have an option to add 'New' items to the database. This is a populated MS Access DB with an autogenerated Primary Key. I'm using a ODBC connection.

If I choose to add New data just for the heck of it, I get the following exceptions.

[codesnippet]MicroFour.StrataFrame.Business.BusinessLayerException was unhandled

I have a funny feeling this is going to be very obvious, but I think I need another pair of eyes!

Greg is correct. You havn't setup your connection for thsi data source. You will add this in the Appmain.vb or program.cs file in the SetDataSources method. You can also refer the docs on this as well.

The inner exception likely provides the key:

[codesnippet]InnerException: MicroFour.StrataFrame.Data.DataLayerException
Message="The DataSourceKey [] is not defined."
Source="MicroFour StrataFrame Business"[/codesnippet]

I'm guessing this means that it can't find the default data source, which has a key of "" (empty string). So, did you define your data source(s) in the SetDataSources event handler is AppMain.vb (programs.cs for C#)? What key did you use for the datasource(s)? Did you setup your BOs to use the appropriate key?
