I'm creating an ASP.net website with 3 layers (Presentation, BLL and DAL).
BLL and DAL are 'class library'. DAL has a typed dataset. Presentation refers BLL and BLL refers DAL.
I wanna populate my GridViews with ObjectDataSource, but it only shows me the DAL. Nothing from BLL...
What am I doing wrong?

Can we specify two different methods as SelectMethod of ObjectDataSource at two different events?
I need my Objectdatasource to get filled with one method while at button click event I want to fill it with other overloaded method.
Both the methods have same name and return same data type but they have different input parameters.

I started learning LINQ, So i thought of just creating gridview with sorting and paging using objectdatasource using LINQ. So i got this link
[URL] which Brian Orrel tell us how to do using IQueryable Interface. but i have nearly 300 lines of stored procedure which joins nearly 20 tables. so i thought of creating a stored procedure and using that instead of IQuerytable.

I'm using the 'Configure Data Source' wizard to connect to my database and show the dataset in Gridview. I want to be able to update, insert and delete entries but am unsure how to build the query. I can write simple update statments to change database entries but how can I do this for entries that have been changed within the gridview?

Could you teach me how to make girdview pass my object (with all it properties) to my ObjectDataSource delete method please?So far the object received by the delete method has only the datakey value, other properties are null.From this article indicates that this is default behaviour - ttp://www.manuelabadia.com/blog/PermaLink,guid,c72852ae-1fdd-4934-a715-f565ceaf21cc.aspxBut i need the other properties pass to the delete method too so i can do other thing before I actually delete the record.

How and where can I get the returnvalue from my "DeleteGuestById" method to show the right error message to my user?
I have this:
Protected Sub gvGuestlist_OnRowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvGuestlist.RowCommand
If e.CommandName = "DeleteGuest" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim data As DataKey = gvGuestlist.DataKeys(index)
Dim GuestId As Integer = data.Values("id")
odsGuestlist.DeleteParameters.Clear()
odsGuestlist.DeleteParameters.Add("id", GuestId)
odsGuestlist.Delete()
End If
End Sub
In my BLL:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Update, False)> Public Function DeleteGuestById(ByVal ID As Integer) As Integer
Dim returnval As Integer
GuestlistAdapter.DeleteGuestById(ID, returnval)
Return returnval
End Function
I think I have to be in the ObjectDatasources' "OnDeleted" method but I have no what code to place there.

In my application there are some GridView(GV) controls. Deletion is already implementd in GV's RowCommand.
Now GVs are bound to ObjectDataSource(ODS). So, whenever a deletion is performed I run into situation like
"System.NotSupportedException: Deleting is not supported by ObjectDataSource.........."
So, I have created a Delete method in the DAL that does nothing and hooked it up to the ODS via its DeleteMethod property.
My question is, is it possible to suppress the Delete event of the ODS? So, when something is deleted thru GV, it will be handled in the GV's RowCommand and ODS' Delete event handler is not called.

i have this class
class MyDal
{
IList<MyData> GetAll(string orderBy, , int count, int firstIndex, out int totalRowCount);
}
i'm using an objectdatasource with MyDal to bind values to a gridview.
i want know if there's a way to configure the objectdatasource to use the parameter totalRowCount without calling the SelectCountMethod.

So, I have 3 table adapters in my dataset, and trying to configure the objectDataSource will not give me the option to select the correct table adapter.
I set up a temporary website to illustrate what I am talking about, along with pics, not much, just 4 pics.
https://sites.google.com/site/configuringobjectdatasource/
The first 2 pics are irrelevant but just in case anyone thinking I don't have it set up properly. The other table adapters are working fine, which I have gridviews being populated etc.
why it will not give me the option to select aspnet_GetRecordDatesTableAdapter?

Hi,
I'm attempting to develop an n-tier web application that makes use of the ObjectDataSource on a page. The page shows the classic 'user details' page to allow create, read, update and delete actions for an object within the users collection. Let me explain
that again as I think it might be the root of my issue. I have a class named 'user', I also have a class named 'users' which exposes a list of 'user' objects. It's this 'users' class that is the source of my ObjectDataSource control.
What i'm hoping to have happen is that the page will display a 'user' object from the 'users' class (which it does) and that the end user can then amend the values in a formview before updating them (it kind of does this). The problem I'm running into is
that all the 'user' objects are getting updated with th ealtered values and not just the currently displayed object. I suspect that this has something to do with the web being stateless, but i'm going 'round in circles trying to figure out where i'm going
wrong.
I can post code if required, but what i'm looking for is a decent (read as: easy to follow/understand) site where I can get a better understanding of what i'm supposed to be doing.
My environment is VS2010, C#, .NET 2.0, but I don't think the environment is the issue, merly the chair-keyboard interface.
Thanks,
Mike

Here is the "Update" method which is not updating.
It works if I remove "@original_UnitPrice" and "@original_OnHand" parameters from the "WHERE" clause.
