ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'insertCourse'

I am trying to use the detailsView on my page to allow for the insertion and editting of course records in my system.  this is my first time using them as my previouse 2.0 outings i have just coded the forms myself and worked that way.  for almost 2 days now i have been fighting with this problem but cant seem to find an answer, i keep getting the error message:

 ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'insertCourse' that has parameters: courseCode, venueID, typeID, programmeID, title, subTitle, description, accreditted, startDate, endDate, price, taster, seats, courseProgrammeID, courseSubTitle, venueName, courseTypeID, courseID, courseDescription, courseBookingPrice, tasterEvent, courseTypeName, courseEndDate, courseProgrammeName, courseTitle, numberOfSeats, courseAccredited, courseStartDate.

Which is right becuase i dont have a method with that many parameters in my BAL, for some reason the engine seems to want to pass the values + the older values i guess to implement optimistic concurrency on the records.  My problem is i dont have optimistic concurrency turned on, neither do i want it as the system will be managed by one person.  I have searched high and low and have not been able to find anything that works, I dont understand why i have a paremters collection if the object data source is going to ignore it and not bother implementing the paramaters that i want to send, and then send them AND other parameters it makes no sense.  I am very close to giving up and going back to the old way of doing things of just wiring up the forms manually, as i would have done that by now the time i have spent trying to figure this out.

 Has anyone got any ideas.....pLLLEAAASSEEE!!! :-)

Please post your web and BAL code.

Look at mark-up of ObjectDataSource. There, can exists a attribute like as "oldValues={0}". Remove it.

Tell me if that works.

 Thanks for responses.

 i dont have the oldValues attribute, i know that was a possible solition but coudnt find it in the sourse.

 BAL to retirieve records

1            Public Shared Function getCourses()
2                Return getCourses(1, course.MaxRows)
3            End Function

Then this

1            Public Shared Function getCourses(ByVal startRowIndex As Integer, ByVal maximumRows As Integer) As List(Of course)
3                Dim courses As List(Of course)
4                Dim key As String = "Courses_courses_" & startRowIndex.ToString() & "_" & maximumRows.ToString()
6                If (courseBase.settings.enableCaching And BizObject.cache(key) IsNot Nothing) Then
7                    'courses are in the cache so grab them out of there instead of hitting our DB
8                    courses = CType(BizObject.cache(key), List(Of course))
9                Else
10                   'Create new instance of Data Class
11                   Dim courseData As New Data.courseProvider()
13                   'Get courseDetails List and load into recordset
14                   Dim recordset As List(Of courseDetails) = courseData.getCourses(getPageIndex(startRowIndex, maximumRows), maximumRows)
16                   Dim test As Integer = getPageIndex(startRowIndex, maximumRows)
18                   'Convert recordset of courseDetails into course list
19                   courses = getCoursesListFromCourseDetailsList(recordset)
21                   'Cache the data
22                   courseBase.cacheData(key, courses)
23               End If
25               'Return the courses
26               Return courses
28           End Function


1            Private Shared Function getCoursesListFromCourseDetailsList(ByVal recordset As List(Of courseDetails)) As List(Of course)
3                Dim courses As New List(Of course)
5                For Each record As courseDetails In recordset
6                    courses.Add(getCourseFromCourseDetails(record))
7                Next
9                Return courses
11           End Function

 This works and i get the values into a gridView all nice up untill now.  My insert function is....

1            Public Shared Function insertCourse(ByVal courseCode As String, ByVal venueID As Integer, ByVal typeID As Integer, _
2                ByVal programmeID As Integer, ByVal title As String, ByVal subTitle As String, ByVal description As String, _
3                ByVal accreditted As Boolean, ByVal startDate As DateTime, ByVal endDate As DateTime, ByVal price As Double, _
4                ByVal taster As Boolean, ByVal seats As Integer) As Integer
6                'Create new instance of data class
7                Dim courseData As New Data.courseProvider()
9                'Create courseDetails object
10               Dim record As New courseDetails(0, courseCode, typeID, "", venueID, "", programmeID, "", title, subTitle, _
11                   description, accreditted, startDate, endDate, price, taster, seats)
13               'Insert the course
14               Dim courseID As Integer = courseData.insertCourse(record)
16               'Purge the cache
17               BizObject.purgeCacheItems("Courses_course")
19               Return courseID
21           End Function

 It is just insert procedure (and probeble the update which i havent tried yet)  I am confused.



9/6/2007 1:16:34 PM

I´m don´t certain about that, but try to remove UpdateParameters. Leave just InputParameters. Cause if you implement Inserting and Updating events (that is something that you can use too) you don´t use UpdateParameters. Just InputParameters. I think that works.

Normally, I don´t use that Parameters in mark-up, cause I use a entities class to set the values between business class and ObjectDataSource. I always use Inserting/Updating events, cause I can set my own parameters. However, I don´t use Bind() on controls when I use FormView.

9/6/2007 1:34:58 PM

I removed the paramters but still had an error.  It seemed that the insert was picking up the values and then picking up the bound columns of the dataView.  I removed them and replaced them with templateItems, which gets rid of the first error but then doesnt pass on any value when i hit the insert button, it simply runs the insert code but with no values??? how do i get the data source to understand i am using templateItems instead of bound items and use those values to insert?

 This is very frustrating  Sad

9/6/2007 2:34:31 PM

I never use DetailView, just FormView and GridView, but both must be a same thing. Don´t set Fields collection inside a DetailView. Input the HTML with yours fields normally. In text property of TextBoxes, place Text='<# Bind("MyField") />'

If don´t works, try use a FormView. It´s looks like a DetailView. I never use Fields collection to do that.

9/6/2007 3:17:01 PM

Thank you for all your replies, i have it working now.

 1) i converted all the fields i needed to template fields which i needed anyway so i dont think this was a big deal and i dont think this fixed it

2) made sure my insert function variables matched the names of the course object e.g. courseTypeID and not typeID which is what i had and it has gone through. this is what fixed it, and i do understand why it wasnt working now.

 Wish this hadnt wasted so much time and i feel a little bit dim for not seeing that before, but i guess we live and learn.

 Thanks again all.
