It’s inevitable, you will want to build an XPATH query that the Filter Builder control can’t support so you end up going in through Advanced View to view/edit the Filter XOML directly. This works but the Filter builder just won’t render your query any longer. The SearchScope object doesn’t even provide a Filter Builder yet because it uses a different Filter attribute under the hood; however we can change the Create or Edit OVC configuration for Sets to include the ability to view this attribute. As always, you will want to save the default export of the Set OVC but crack that puppy open and insert this control right after the FilterBuilder control.

<my:Control my:Name="Filter" my:TypeName="UocTextBox" my:Caption="{Binding Source=schema, Path=Filter.DisplayName}" my:AutoPostback="true" my:Description="Raw Filter XOML" my:RightsLevel="{Binding Source=rights, Path=Filter}">
<my:Properties>
<my:Property my:Name="Rows" my:Value="10"/>
<my:Property my:Name="Columns" my:Value="60"/>
<my:Property my:Name="MaxLength" my:Value="500"/>
<my:Property my:Name="Text" my:Value="{Binding Source=object, Path=Filter, Mode=TwoWay}"/>
my:Properties>
my:Control>

By setting the AutoPostback value here to true we also allow for direct edits to refresh the Filter Builder, assuming your updates aren’t using an unsupported operation. Load the updated file back into the OVC object and then IISRESET. When you are done the control should render like so:



If you’d like more real estate here like this:



…then what you want to do is change the Columns to 120 and add the my:ExpandArea="true" directive on the Control line like so:

<my:Control my:Name="Filter" my:TypeName="UocTextBox" my:Caption="{Binding Source=schema, Path=Filter.DisplayName}" my:ExpandArea="true" my:AutoPostback="true" my:Description="Raw Filter XOML" my:RightsLevel="{Binding Source=rights, Path=Filter}">

I’m happy to report that the 4th edition of the Active Directory book from O’Reilly is out and I can’t wait until I get my hands on a copy! The new edition covers everything you wanted to know about the changes to Active Directory in Windows Server 2008. I started with the original 1st edition and it remains my preferred work on AD, so go get it!
