I have a datalist (DataList1)...
with an itemtemplate...
then a table - server side (Table1)...
then another datalist (DataList2)...
another itemtemplate...
another table - server side (Table2)
DataList1 is bound to an objectdatasourc e (ObjectDataSour ce1), and has a
datakey (CategoryId). I want to bind DataList2 to another objectdatasourc e
(ObjectDataSour ce2), pulling records based on DataList1's datakey
(CategoryId).
I've set everything up, but when i run the page only DataList1 appears to
databind. Table1 renders out, but DataList2 never seems to databind.
I'm trying to do everything declaritively, is that possible? If so, what am
I doing worng?
Thanks

Make sure that the datasource for DataList2 is within the same template that
the DataList2 is placed, because for each datalist2 instance there will be an
instance of the datasource created. I have a demo that achieved the same
declaratively albeit using a parent GridView that expands a child GridView
that in turn expands a DetailsView. http://www.webswapp.com/CodeSamples/...idView_1c.aspx

Thanks for the reply. I didn't realize that the position of the
objectdatasourc e control mattered, but apparently it does. The only
difference here is that I wanted to do the databinding without a selection
occuring (meaning there is no SelectedIndex for me to reference). I solved
this problem by putting a Label control in the first datalist and binding the
text property to the categoryId (but made the label control hidden). Then I
used the controlparamete r of the second object datasource and referenced the
text property of the label.
I read that part of the solution last night somewhere, don't remember where
as I wasn't able to get it working then (likely due to the position of the
datasource control).
All-in-all, everything seems to be working now. Thanks again for the reply,
and nice samples on your site there.
Thanks.

Hi there
My problem is that in when I update GridView row, which is nested into
DataList control, I want to refresh also DataList in which the GridView
is nested, since after update, trigger in my DB changes some value in
it (some Total sum from the GridView column).
The GridView, along with its ObjectDataSource is inserted into DataList
ItemTemplate.
