Maximium value for AutoCompleteExtender

Question

I have a AutoCompleteExtender with the following code:

 <ajaxToolkit:AutoCompleteExtender runat="server" ID="autoCompleteOrigem" TargetControlID="txtClienteOrigem"
                            ServicePath="~/Cliente/AutoCompleteCliSubCli/HandlerCliente.asmx" ServiceMethod="RetornaClientePesquisaOrigem"
                            MinimumPrefixLength="2" CompletionInterval="100" EnableCaching="true" CompletionSetCount="20"
                            OnClientPopulating="autoCompleteOrigem_OnClientPopulated" CompletionListCssClass="AutoExtender"
                            CompletionListItemCssClass="AutoExtenderList" CompletionListHighlightedItemCssClass="AutoExtenderHighlight"
                            CompletionListElementID="listPlacement" OnClientItemSelected="SetSelectedValueOrigem">
                        </ajaxToolkit:AutoCompleteExtender>

I have a problem, with this it only shows 5 lines with a scroll bar.Like the image.

I need to change this to show 20 but i couln'd find the property to change.Someone knows if is it possible with this component?

You can increase the height of the popup using the height CSS attribute of CompletionListCssClass.

In your case it will look like this:

.AutoExtender {
    height: 200px;
}
