    1. COHi Stingyjack....thanks for the reply. The function is just merely an exercise in trying to figure out what to class and what not to, but I do understand and appreciate the point. I'm still getting that Specified Cast is Not Valid error however. I'm really puzzled and looked all through my data context definitions to see if something is strange there. Is there a way to simply check if the single query works without having to cast it as a tblPolicy? In other words can I perform a LINQ query and throw it into just any ol object like Response.Write(newpolobject(0).ToString() or something?

    2. COWell... I am trying to say there is no need to pass in a function [Function(p)] for this simple statement. GetJacketByPolicyID returns a tblPolicy, just as the linq query does. I still dont get why you are trying to cast it to something different. Also its worth noting that the VB syntax for linq is a bit different than C# and VB doesn't support (at least without heinous workarounds) some of it completely (like functions) yet.

    3. COThanks so much StingyJack, yeah I don't like VB.net much and prefer C# any day of the week, but my client is new to .net and wanted to have a base language that they were familiar with, hence the vb.net...lol. Anyway, I did get this to work. I had to delete and let .net rebuild the DataContexts and it worked like a charm. Thanks again.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
