I had 5 pages in their own web-site. These pages have now been moved
to another web-site. Everything is fine except that one of the pages,
which I had trouble with in the past (i.e. same problem), is now
partly broke. The paging no longer fully works in the gridview.
The gvAwarded_RowDa taBound code works to load the ddlPager with the
correct number of pages.
The lnkPagerBack, and lnkPager controls continue to work at
incrementing and decrementing the page count but the ddlPager,
DropDownList, does not even post back when I click it (i.e. in debug
mode it does not run the server event).
What have I done wrong!
PS: The PagerTemplate has now been AJAXified (but it doesn't work
without the AJAX anyhow!, so I can't see how AJAX could be an issue -
although, the new site has some AJAX and the old site (from which it
was moved) has none.).
I've put the relevant code below.
