DataSourceKey Not Defined

Clayton Hoyt — Fri, 29 Sep 2006 08:05:53 GMT

Hi Folks

I have a business object assembly that will provide data to a web site. I have everything wired up but when I run it, I get the following error. Where do I set the DataSourceKey? In the past, I have always put a connection string this in an App or Web Config and gone from there. I am obviously missing something simple.

"MicroFour.StrataFrame.Data.DataLayerException: An error occurred while creating a new DataLayer for the business object. ---> MicroFour.StrataFrame.Data.DataLayerException: The DataSourceKey [] is not defined.

Yeah, that's it. The base class is DbDataSourceItem, so sometimes my brain likes to add the Db in the class name...sorry for the confusion :hehe:

ok...dumb question #2.:hehe:..where is the SqlDbDataSourceItem located? I've searched the object viewer, your documetation and the web and come up empty. I also looked for SqlDBDataSource which sounded familiar but no go on that one either.

Thanks!

Yes. You need to define this in the Application_Start method of the global.asax file. You will just manually specify the data source:

MicroFour.StrataFrame.Data.Databasics.DataSources.Add(New SqlDbDataSourceItem("","Your connection string"))
