I have written an eventhandler which is getting called on FieldFilterEditorCreated.     Depending on which column the type of the e.Editor changes.   But regardless, when I set a value in the width property of this editor it has no effect.    It comes is as "NaN".    I try to set the value.   It doesn't have any effect.   Even if I set it to a huge number, the size of the filter editor box remains unchanged.

Incidentally I see the FieldFilterEditorCreated event getting called TWICE when I click the funnel.    Both times on entry the value in e.Editor.Width is "Nan" and when I set it both times...still no change.

I was able to resolve my issue by putting the following into the resourcedictionary section of the xaml for the base class:

<ResourceDictionary 
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" >
<Style TargetType="telerik:FilteringControl">
           <Setter Property="Width" Value="Auto"/>
</Style>
