formview and datasource as collection

[Mike Gaab]

I am trying to use some of the new controls in VS 2005 but
am having some difficulty.

My business logic layer returns Collections of my business objects.
I am used to just assigning these collections to a datagrid's datasource
property. With the new controls I can still do the same but it appears
that the automatic insert,edit, etc. features are not enabled if I do so.

I see that the Formview, and others, have a DataSourceID property
but my Collections don't implement the IDataSource interface nor am
I completely comfortable implementing it.

I hestitate to use the new ObjectDataSource control because it seems
like I lose some flexibility. I am used to manipulating collections.

Any thoughts.
Thanks Mike

An example, if I am using a Formview and I set it up with the edit
templates, etc. and then assign my collection of business object to the
Formview's DataSource, I don't get any of the free functionality with
the templated items.

It seems like I should be able to switch modes at runtime.
I've tried doing that using the ChangeMode(...) method but
I must be missing something.

I did finally get this to work. The only thing that I don't completely
understand is that I must call DataBind() after ChangeMode(...).
If I don't call DataBind(), nothing happens. Does that make sense
or is that just a hack. I am not used to
programming in .Net so some stuff is a tad foreign. Getting there but
it is taking a while.
