Hello I'm having a problem where the AutoComplete Control used in a DataTemplate has it's dropdown default to the orientation of the ItemPanelTemplate. If I set the orientation there it changes the orientation in the AutoComplete.

I have the AutoComplete contained in a StackPanel with the Orientation set to Vertical.

Psudo code follows:

<DataTemplate x:Key="FieldTemplate" DataType="{x:Type MyType}">
<Border>
<ScrollViewer >
<StackPanel Orientation="Vertical">
<syncfusion:AutoComplete Name="myAutoComp"
Source="Custom" IsAutoAppend="True"
IsHistory="False" IsAutoCompleteItem="False"
IsFilter="True" Text="{Binding MyProperty}">
</StackPanel>
</ScrollViewer>
</Border>

<ListBox x:Name="Main" ItemTemplateSelector="{StaticResource DataTemplateSel}">
<ListBox.Resources>
<Style TargetType="{x:Type ListBox}"
BasedOn="{StaticResource {x:Type ListBox}}">
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemPanelTemplate>
<WrapPanel Orientation="Horizontal" />
</ItemPanelTemplate>
</Setter.Value>
</Setter>
</Style
</ListBox.Resources>
