Datalist selects Item after first click, but does apply the SelectedItemTemplate after the second click only

[Dirk Meusel]

Background:
On my webform a simple datalist shows one column. The databind is done
in the page_load event. In the ItemTemplate a linkbutton serves for
providing the Select Command.

Problem:
When I click a item to be selected, the datalist applies the
SelectedItemStyle on that Item, but not the SelectedItemTemplate. When
I click the same Item a second time asp.net applies both the
SelectedItemStyle and the SelectedItemTemplate, but does not fire the
OnSelectedItemChanged event.

What is to do to select the item with the first click properly???
