I thought I was getting the hang of all these wpf controls until I tried to put a checkbox and text in the XamComboEditor.  The combobox is for a chat application, the selected item is the channel to send out on, the checkboxes are the channels to receive information from.

I can get the combination to work but I have two problems.  The first is the ComboBoxDataItem has a white border around it that I can't change to black.  The second item is when I click on the text it doesn't select the item (this is great for the checkbox, bad for the name).  I have to click to the right of the name to select it.

My questions are 1) How do I turn the ComboBoxDataItem border to black, and 2) how do I get the click on the text to execute select item in the XamComboEditor. Below is my xaml and the C# code to fill the

<Editors:XamComboEditor Grid.Column="3"
                        Grid.Row="1"
                        SelectedItemChanged="ChannelBoxOnSelectedItemChanged"
                        CheckBox.Checked="ChannelBoxOnChecked"
                        Background="Black"
                        Foreground="White"
                        Name="ChannelBox"
                        IsAlwaysInEditMode="True"
                        HorizontalContentAlignment="Stretch"
                        HorizontalAlignment="Stretch">
<Editors:XamComboEditor.Resources>
     <DataTemplate DataType="{x:Type Editors:ComboBoxDataItem}">
          <StackPanel Orientation="Horizontal"
                      Background="Black">
               <CheckBox IsChecked="{Binding Path=Value.IsChecked}"
                         VerticalAlignment="Center">
               </CheckBox>
               <TextBox Text="{Binding Path=Value.Name}"
                                 VerticalAlignment="Center"
                                 Margin="3,0,0,0"
                                 Foreground="White"
                                 Background="Black">
                </TextBox>
          </StackPanel>
     </DataTemplate>
</Editors:XamComboEditor.Resources>
</Editors:XamComboEditor>


(ChannelList has an object with two properties, Name and IsChecked)

var itemsProvider = new ComboBoxItemsProvider();
for (int i = 0; i < ChannelList.Length - 1; i++)
{
      var cb = new ComboBoxDataItem { Value = ChannelList[i] };
      itemsProvider.Items.Add(cb);
}
 ChannelBox.ItemsProvider = itemsProvider;
