I don't remember if there is such property in a combobox, but you always can alter a default control template. In your case you should specify a width property of a popup element in a control template. Here is a sample code, taken from one of the WPF themes from Codeplex:

 <ControlTemplate x:Key="ComboBoxTemplate" TargetType="{x:Type ComboBox}">
   ...
      <Popup ... Width="100" >
   ...
 </ControlTemplate>

This is a general idea. You can look in a themes source code fore more information. This MSDN pages can also be helpful:
