Thanks for your response JoBeetz,
En, not sure whether I've completely got your point. What I think currently
is that you want to get rid of the DataSource control which rely on the
page's lifecycle and automatically retrieve data and do the databinding on
those databound control(gridview, detailsview.....), you're wantting to use
some datasource from other source or storage, like sessionstate, cache or
....., am I misunderstanding?
If this is what you want , I think that's quite simple since we can still
using the ASP.NET 1.1 databinding style, set the Databound control's
DataSource to any datasource Object(not necessarily a datasource
control....) and call the databind() method....
Just as I've mentioned in previous message,
ItemCommand ( object sender, xxxeventArgs e)
{
GridView1.EditIndex =e.Item.ItemIndex;
GridView1.DataSource = GetDataSourceFromSession();
GridView1.DataBind();
}
this still work well. Also, if the GridView or other databound control
is dynamically created (you should create and add them into page in Page's
Init or Load event....), we can also use such means or just assign an
existing DataSourcecontrol's ID to its DataSourceID property to perform
databinding.....
Thanks,
Steven Cheng

| Heh heh. That's exactly what I do in response to a button in the data
grid.
|
| I think my biggest problem with this is mostly that, to use an
| ObjectDataSource, the objectdata source has to get its data completely
out of
| the context of the page. This makes a dynamic gridview, which can'tbe
| constructed until some aspect of the page is derived, a real pain. If
you
| use a detached class as the object source, I need that class to have
access
| to the session contents to deliver session specific data.
|
| How can I do this? Thanks,
