This might be something as simple as spitting it out to the console, or as complex as binding it to a read/write hierarchical Data Grid.

If the table object was null, the I set the Update flag to false.If you look at my previous example you will notice that the html markup above is a bit similar.The things that are added above are Buttons for Edit, Delete, Update and Cancel which is by default set their enable property to false, this is to prevent users from doing certain actions when the page is loaded in the browser. Or you did nothing the the auto-generated file contents but the error is thrown out? Submit Changes() Hello cppvb:) Have you modified the LINQ generated file's contents?Basically I’m going to show you the basic way on how to edit and delete data from the form and update the database using L2S technology.

Since this is a continuation of my previous example so I would suggest you to refer that first before you go any further.

I can't imagine this is the optimal coding for data table update operations, but it might be.

Is this a possibility in LINQ (I'm completely new to LINQ)?

Students Where p.student_id = Cur Student.student_id Select p).

Attach(_Employee, true); or Using context As New db Students(str Conn String) Dim tmp Student = (From p In context.

I use an Update boolean variable to tell me if the information on the WPF window is to update, or to add.
