Thanks for help on this, Looking at moving from Access and I'm impressed with the deployment possibilities of LS along with the RAD focus (great name too - Lightswitch). Struggling with something that I'm sure is simple but I'm missing - how do I add a column/field to a query or a datagrid from a related table in LS.  I've tried adding a Data Item in a screen, bit I can't add a field to the grid, and there doesn't seem to be any options to add fields in the query builder. What am I missing folks? Brad

Hi On creating a new many to many record, all it has is the 2 fields with keys to the other 2 tables. I need to add fields from the associated tables so that it has searchable fields on the screen. However I cannot seem to bind to the newly created record. This is the code I wrote to add the store name to the new record but it just picks up an existing selected record and not the new one. Please assist. Thanks, Mark. partial void GroupList_Changed(NotifyCollectionChangedEventArgs e) { if (e.Action == NotifyCollectionChangedAction.Add) { foreach (GroupList Gr in e.NewItems) { Gr.StoreName = this.Stores.SelectedItem.Name; } } } Mark

I got a new laptop recently, and installed both Visual Studio 2010 and 2012. I went into Visual Studio 2012 and got the latest version of a C# Lightswitch project from Team Foundation Server (which we use for source control). I then switched the solution explorer to 'File View' so that I could look at the User Code.  Any code file that I look at contains the error (listed on the title) on all of the methods contained in the code files.  I've done a lot of searching, and came across some suggestions from Yann Duran in Lightswitch thread  entitled Overwriting a Lightswitch Query produces Error "no defining declaration found for implementing declaration of partial method".  I've rebuilt the solution, Unloaded and reloaded the project, and also repaired Visual Studio.  I still have the errors in my code files. I think that this project may have been originally created in Microsoft Visual Studio Lightswitch 2011, so I installed it,
