What does ObjectDataSource.Update do?

Hi,

I have a FormView control which I'm trying to have automatically update when the user changes pages (I'm duplicating an Access front-end, and in Access you don't explicitly have to "Update" a record to save your changes to it - you just go to a different record).

My FormView uses an object datasource that I declared on the ASPX page. Maybe that's my problem.

Anyway, I wrote this method...

Code:

Protected Sub FormViewPaging(ByVal sender As Object, ByVal e As FormViewPageEventArgs) Handles FormView1.PageIndexChanging
        Me.ObjectDataSource2.Update()
End Sub

Which doesn't do a damn thing.

So what I really want to do is two thing:

(1) Update the FormView's underlying dataset
(2) Update the underlying database

Any Suggestions? Thanks.

Aaron

Well I think I have answered my own question. The short answer is: it can't be done. Just forget it, hang it up and go home.

We, as developers, have no access to any datasource that was set up declaratively. If you want programmetic access to thd data in a FormView (or GridView or DetailsView for that matter), you have to bite the bullet do the data binding manually. This of course means you have to do everything else manually as well. There doesn't seem to be a happy medium.

So my paging handler features a standard update routine where I get references to all the controls, set up SQL Paramaters and execute an update query. Very tedius, since the form has 60 controls on it. But Oh Well.

Thanks for reading.
