Here's my situation, in brief: we're using ASP.NET 2.0, and
we've
incorporated the Ajax Toolkit library. On one of our
important pages,
we're using the ajaxToolkit:TabContainer control to several
different
by related datasets, each on their own tab.
With fully 6 tabs on the page, each of which has a GridView
that's
(pretty efficiently) showing 20 rows of data retrieved from
SQL
Server, it starts to bog down pretty quickly. Each GridView
is bound
to an ObjectDataSource which performs a bit of logic and
then makes a
call into a related API to fetch the data. However with
each
postback, each of the ObjectDataSources' Select methods are
being
invoked.
My basic question is: is there a way I can take over control
of the
DataBinding sequence in a way that I manually keep track fo
which
tab's controls need to be bound and invoke it selectively?
That is,
it seems to me that every control is re-bound every time,
when by
definition only one out of the six is displayed (and even
that one may
not need to be re-bound in many cases). I don't want
page-level D-
binding to take place; I want to instruct only the active
tab to do
its thing as I see fit.
This feels like a situation when the architecture has
provided so much
infrastructure that I no longer have any idea how things
are
happening, or why. I tried to override the DataBind method
on the
page, and in my override I did NOT call the base method,
hoping that
would effectively squash the automatic page-level binding,
but it
carries on normally anyway. What am I missing?
Thanks in advance.
