Hey!

To allow filter in the dropdown list, I changed from the Window XamComboEditor to Infragistics.Controls.Editors.XamComboEditor component.

When I changed the component IsTabStop no longer worked. The XamComboEditor is used in a custom user controler and we have a IsTabStop dependency property where we bind the XamComboEditor IsTabStop to the IsTapStop property.  Why did this feature no longer work when we changed the component?

<ig:XamComboEditor x:Name="ComboBox"
IsTabStop="{Binding IsTabStop}"
Tag="{Binding WatermarkText}"
ToolTip="{Binding WatermarkText}"
CustomValueEnteredAction="Allow"
IsEditable="{Binding IsEditable}"
SelectionChanged="ComboBox_OnSelectionChanged"
AllowFiltering="True"
CustomItemsFilter="{Binding CustromFilter}"
BorderThickness="{Binding InvalidBorderThickness}"
ItemsSource="{Binding ComboboxItemSource}"
DisplayMemberPath="{Binding DisplayMemberPath}"
SelectedItem="{Binding SelectedComboboxItem}"
BorderBrush="{Binding UnvalidComboboxItem, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
Width="{Binding ComboWidth}"
Loaded="PipelineComboBox_Loaded"
FontWeight="{Binding IsDirty, Mode=TwoWay, Converter={StaticResource BoolToFontWeightConverter}}"
KeyUp="ComboBox_OnKeyUp"
MouseUp="ComboBox_OnMouseUp"
