Improve this question. What error does it throw? Runtime exception? Whenevr I am changing Connection string to my local connection string, it will not hold in that dbml file property. I created a new one, then tried connection to database, connection failed. I changed the password and saved and it changes to another connection string — arun thakur.
Add a comment. I would recommend using the visual designer built into VS, as updating the dbml also updates the code that is generated for you. Modifying the dbml outside of the visual designer would result in the underlying code being out of sync. There is a nuance to updating tables then updating the DBML Foreign key relationships are not immediately always brought over if changes are made to existing tables. The work around is to do a build of the project and then re-add the tables again.
I reported this to MS and its being fixed for VS DBML display does not show new foreign key constraints. In the case of stored procedure update, you should delete it from the. But if the stored procedure have two paths ex: if something; display some columns; else display some other columns , make sure the two paths have the same columns aliases!!!
Otherwise only the first path columns will exist. Here is the complete step-by-step method that worked for me in order to update the LINQ to SQL dbml and associated files to include a new column that I added to one of the database tables. You need to make the changes to your design surface as suggested by other above; however, you need to do some extra steps.
These are the complete steps:. Copy the new column from this "new" table to the "old" table see M answer for details on this step. Delete the. Clean and Rebuild the solution this will rebuild the.

I had tried 1a and 1c without 1b and was getting 'Specified cast is not valid' errors when performing a simple select on a view. Including 1b fixed it for me — tomfumb. OmegaMan, I am using Team System and the codes are stored on a saperate server.
I opened the project from a source control. I look at the path that the code files are stored in my computer, but there is no. I think the problem is that the project was not created as a "web project", but it was created as a "website" application. Thanks for your help I dont know what to do though I assume you do not get any compile errors. Then at some point you have added another table to the l2s class, and the code for the table does not get added to the l2s class.
Is that correct? If you right-click the dbml file in solution explorer and Run Custom Tool, do you get any errors? When you add a table, you have to Build the web site for it to appear in Intellisense The build action is when the custom tool runs. Toby Toby. Well the celebration was premature The Linq-to-Sql support in VS is very fragile.
I had this dbml class working fine with the added table, but further updates pull you back into the black hole of corruption done by the custom tool.
By that I mean, just something simple like adding a property to an existing table, save the dbml, then the designer. Yes, right there in the Pending Changes window of TFS and missing from Solution Explorer Digging into the csproj file and comparing a dbml that seems to work vs the broken one I see some differences: a - working one did not have a partial class for the datacontext, so the designer.
Ah Ha! Clues - partial class by itself doesn't cause a problem, designer. Some other tidbits from my spelunking In my project, I have a folder for each database. Looks like a bug to me! Com Only in asp. Tuesday, July 14, AM. After that the link should work. Anyway, the workaround described behind that link is to move any using statements inside the namespace declaration if you have a partial datacontext class with your own code in Odd thing but that's the way it works But I once got some funny issues when I had files in the same folder called [datacontext].
Renaming the latter to sometihng else fixed it. Tuesday, July 14, PM.
