I have a continious Form which opens and shows records of people with whatever criteria the user had chosen the screen before. When the form opens it checks which button was pressed and then changes the recordsource of the continious form.
When I try to edit the records it says "Recordset not updateable". I have done everything I can think of, I have change the type of recordset from dbopensnapshot to dbopendynaset.
I'm working in a windows app. with vb.net it is working very fine with me but after I make it as a setup file and install it it shows an error.I will explane the problem hereunder:the App. is for importing the data from xsl.file(user select it from file dialog)and store it in DB access file. It works pretty good when it is running in VS .. but after installation it is not.The error msg: "Operation must use an updateable query.""When JIT debugging is enabled, any unhandled exception.will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box."

Operation must use an updateable query.I dont think it can be a permissions problem or a file access problem because I can execute an insert sql query on the same file.

I've checked all the grid properties I can think of. Is that a result of binding to a Linq data source? Any example code of an updatable grid that uses Linq?

I'd like to have an updateable DataGridView that's bound to a database-driven business object. It needs to handle all aspects of CRUD and be sortable and filterable as well.
Most of them simply bind to an object (non-database, manually filled) and do not allow you to Add, Delete, and Edit records. Furthermore, they basically never show how you would perform sorting and filtering.
I think the biggest things I'm not understanding are:
1) How do you make the DataGridView perform additions, deletions, and edits on an object.
2) How do you program your object to handle additions, deletions, and edits. Do you just need methods that use ADO.Net, NHibernate, or Linq to SQL (or any other CRUD handling mechanism)?
3) How to make this filterable and sortable.
Is this overly difficult to do or why am I have so much trouble finding examples for this?

I have an application in VB6 that joins 3 tables together to create 1 record set and I am able to use the move next and move previous methods to navigate through the record set.
I am having trouble creating this same scenario in vb.net with a data set. Do I have to create each table individually and then link them together somehow or can I join them all together in a query before I fill the data set?

I have a piece of software I am converting to ADO.NET from ADODB. In ADODB I can update a recordset by simply.
Dim rs as ADODB.Recordset
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
OR IF I WANTED TO ADD
Dim rs as ADODB.Recordset
rs.AddNew()
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
I am confused about to easily accomplish this. I know I can use an insert or update command but it would be much easier to do something like this. NOTE: The query just returns a filled RecordSet, it just executes the command and connection without me having to do it all over the place.
