How to copy the displayed data from grid view with LINQ?
Example:
In the GridView I have a data:
ID, Surname
1, Surname1
2, Surname2
3, Surname3
How to copy this information in the same GridView and to add new IDs.
Finally, the copy must look like this:
ID, Surname
4, Surname1
5, Surname2
6, Surname3
I have a number of tables that together make up a "Test" that somebody can take. There are multiple types (scripts) of Test a person can take. I'm working on an Edit function that will allow somebody to edit the Test Questions. I want these edited questions to show up on all new Tests of that type, but still show the old questions when viewing past test scores.
To do this each "Test" has a TestId auto-increment identity (along with its name). When a test is edited I want to make a copy of the test with a new TestId and present the questions for editing.
So what is the best way to make the copy and insert it into my table using LINQ to SQL? This:
DataContext db = new DataContext(ConnectionString);
//Copy old test into identical new test but with a different script ID
var oldScript = db.TestScripts.Single(ds => ds.TestScriptId == oldScriptID);
var newScript = oldScript;
db.TestScripts.InsertOnSubmit(newScript);
db.SubmitChanges();
of course tells me that I Cannot add an entity that already exists.
Is the only way to do this to go through every column in the TestScript and copy it manually, then insert it, and the database will give it a new Id?

View 1 RepliesI've got a Gridview which has a datasource to a particular database.
I've got a DetailsView which has a datasource to a table in another database.
when I select a Gridview row, I need to populate a field in the DetailsView with the Primary Key field (showing in the Gridview) from the Gridview.
Can this be done (if so, how?)?
Also (but not as important) :
If there's no field related in the second table, I'd like it to come up in Insert Mode - if there is a field related, I need it to come up in Edit mode

View 6 RepliesI have an aspx webpage with a databound DropDownList and a databound GridView control. The GridView datasource is using a WHERE clause to return its' data. I.e. The user selects a work area from the DropDownList and members of that area appear in the Gridview. The GridView has 3 columns, WrkArea, LastName and FirstName. The page also has a Button.
What I am trying to accomplish is when the user clicks the Button, the data from the GridView is copied to a separate SQL table. I am working in VB. I have been looking at other posts but have to admit, I am really confused.
