For example Data Source Controls includes controls like Entity Data Source, Linq Data Source, Object Data Source, Site Map Data Source, Sql Data Source, Xml Data Source and Data Control includes recent all excluding pointer as listed below.
A design surface and hundreds of controls and components let you rapidly build sophisticated, powerful UI-driven sites with data access.It is also therefore possible, though not necessary, to create a new Command object to run the Select @@Identity query.The following code shows this in action where the Connection object is opened, then the first query is executed against cmd using Execute Non Query() to perfom the Insert, followed by changing the Command Text property of cmd to "Select @@Identity" and running that. Close() in all these examples: in all the snippets, the Connection object is instantiated within a 'using' block.The built-in functions @@Identity and Scope_Identity() are designed to retrieve the most recently added record's autoincrement identity value from Access and Sql Server respectively. The Jet 4.0 provider supports @@Identity, which means that developers no longer need to use Select Max(ID) or some other contrived method of obtaining new ID values.The key to @@Identity is that it returns the value of an autoincrement column that is generated .

How do I call the Access Data Source1_Inserted sub? thank you sorry for the newbie questions in advance:1. if i have an asp page like Test1- which accesses a static class that calls your code (see #1)Will each different user web session get the correct primary key id value after the insert? When I used the Execute Scalar method, it is showing the wrong record number instead of currently inserted record auto number. Insert() method don't work and the the returned Identity value comes with help please ???(it is a simple, flat access file only providing text similar to a spreadsheet). Thanks in advance Thanks a lot for the information, it is great. I am using the Ole Db Command sample, but it is not inserting the row and im not getting any errors. in your first c sharp example against sql server... Hi Mike, your tutorial is still on top of Google results when searching for 'how to get back auto-incremented id'. One question: I prepare a tree structure of objects - records from a self-referring table - and then I want to commit all the records representing a new sub-tree to database in tree of already stored records (can be loaded partially).In order for this apporach to work, you must reference the im impressed, and i do not even know how to use this information.

When you do that, the resource that's instantiated within them is automatically closed and disposed of at the end of the block. You won't have to wait days for me to get round to managing this site.
