If I make a change to my database (let's say I add a column to a table), is there any magical buttons that I can click to have my Linq to SQL model update to reflect the changes to my table? I had to create two additional columns yesterday, and both times I found myself destroying and then recreating the Linq model.

I made a few changes to the DB in SQL server management studio then right clicked on the .edmx doc to get it to update. That seemed to work fine but when i compiled the app everything that referenced the EF seems to be broken.The Error list now contains the below error for all classes that used it.

View 6 RepliesI have a loop that runs through a variety of websites and I'd like to put some kind of a postback in the loop so that each time through a textbox would refresh with the url that is currently being considered. I don't know AJAX yet so I'd like to redo the webpage. I am currently using a session variable to hold data for display between page loads. I have tried
1) Response.Redirect("Default.aspx");
2) Server.Transfer("Default.aspx");
3) Page_Load(sender, e);
4) this.RaisePostBackEvent(URLTextBox.Text);
but they don't work, possibly because I am not implementing them properly. I'd like to watch the current situation as it is updated within the loop.
I use Linq to Sql (although this is equally applicable in Entity Framework) for my models, and I'm finding myself creating buddy classes for my models all the time. I find this time consuming and repetitive. Is there an easy way to automatically generate these buddy classes based on the models? Perhaps a visual studio macro?

I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty.
My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields?
Sure, I have successfully added the MetadataType(typeof<t>) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?
