How to set background color only for dropdown list box for ComboBox not for the text field? I tried to set Property Background and it seemed ineffective.

I dont't know exacly you need. If you show me a image with your wish. But if I need to change the  appearance of a control I open with Expression Blend 2 and select him. After that I do a reverse click on control in "Objects and Timeline", "Edit Control Parts (Template)", "Edit a Copy" and select to do this in application. Like this:

 Hi Kent,

If you want the dropdown list has the different background color with the text field, you can set the ComboBoxItem's Background, below code work fine on our labs:

<ComboBox Height="40" Margin="49,43,150,0" VerticalAlignment="Top" Background="#FF0F51EB">
          <ComboBoxItem Content="Item1" Background="#FFEC1313"/>
          <ComboBoxItem Content="Item1" Background="#FF24E643"/>
          <ComboBoxItem Content="Item1" Background="#FF8B2CE4"/>
      </ComboBox>

Thanks for your information. My ComboBox uses template for the list item. It looks like:

 <ComboBox x:Name="xMyList" Height="20" Style="{StaticResource FormComboBox}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
              <TextBlock Width="150" Text="{Binding Path=myName}" VerticalAlignment="Center" FontSize="10" />
            </StackPanel>
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

For template there is no backgroupd property. I can set background for Stackpanel, but that only be effective for the list item, between the item in the list , there is a gap with another color. What I want is set the a background color for whole box for the dropdown(Default is white), not each item in the list.
