Confused about Repeater Events! Can anyone help?

I have a repeater, which contains in its <HEADERTEMPLATE> a drop-down
list (set to autopostback).

If the page is a postback, I want to modify the SQL of the repeater's
datasource, DEPENDING ON the value of the drop-down list.

However, I can't evaluate the drop-down list submission at Page_Load,
because the repeater has not yet been databound or rendered, so
effectively the drop-down list doesn't yet exist.

However, if I test the drop-down list value in the Repeater's
OnItemDataBound event, then it's too late to modify the Repeater's
datasource SQL, as it's already databound.

How can I get around this? There must be a way of evaluating something
that exists in the Repeater's HEADERTEMPLATE section, before
databinding the repeater itself...?
 
Something is not clear here. If you re-bind the ddl it will lose the user
selection. Is the ViewState enabled?

In any case you can always take the markup out of the HeaderTemplate and
place it just before the repeater. The html output will be the same. This
will separate the dll from the repeater.

Thank you Eliyahu,

The repeater handles table rows, and I actually thought the opening
<table> tag and initial rows had to be in the <headertemplate>, taking
them outside has solved the problem. Many thanks!
