Hello.

I have autocomplete control which is working perfectly. But if I add animation a dropdown list stops scrolling with up/down arrows.

It is related to IE8.

Does anyone have suggestions how to resolve it. Next is the code:

<ajaxToolkit:AutoCompleteExtender
    runat="server"
    BehaviorID="AutoCompleteEx"
    ID="autoComplete1"
    TargetControlID="txtPayorName"
    ServicePath="~/Public/AutoCompleteService.asmx"
    
    MinimumPrefixLength="1"
    CompletionInterval="1000"
    EnableCaching="true"
    CompletionSetCount="20"                                
    ServiceMethod="GetPayorsList"
    CompletionListCssClass="autocompleteCompletionListElement"
    CompletionListItemCssClass="autocompleteListItem"
    CompletionListHighlightedItemCssClass="autocompleteHighlightedListItem"
    
    DelimiterCharacters="">
    <Animations>
          <OnShow>
                                            <Sequence>
                                                <OpacityAction Opacity='0' />
                                                <HideAction Visible='true' />                                               
                                                <Parallel Duration='.1'>
                                                    <FadeIn />
                                                    <Length PropertyKey='height' StartValue='0' EndValueScript='225' />
                                                </Parallel>
                                            </Sequence>
                                        </OnShow>

                                        <OnHide>
                                            <Parallel Duration='.1'>
                                                <FadeOut />
                                                <Length PropertyKey='height' StartValueScript='225' EndValue='0' />
                                            </Parallel>
                                        </OnHide>
    </Animations>
</ajaxToolkit:AutoCompleteExtender>
