I have a combobox in the TitleTemplate of a grid.  When a button click event fires, I want to loop through all of the comboboxes created by the TitleTemplate (x:Name="ThisComboBox" in the XAML below).  Can you please tell me how access these comboboxes in the code-behind?  (The XAML is listed below):

<xcdg:DataGridControl x:Name="DetailDataGrid"

Grid.Row="0"

AutoCreateColumns="False"

SelectionMode="Extended"

ItemScrollingBehavior="Deferred"

Margin="0,0,0,0"

ItemsSource="{Binding Source={StaticResource FieldsDataSource}}"

FontFamily="Arial">

<xcdg:DataGridControl.Resources>

<DataTemplate x:Key="ColumnTitleDataTemplate">

<StackPanel Orientation="Vertical">

<ComboBox x:Name="ThisComboBox">

<ComboBoxItem IsSelected="True">One</ComboBoxItem>

<ComboBoxItem>Two</ComboBoxItem>

<ComboBoxItem>Three</ComboBoxItem>

</ComboBox>

<TextBlock Text="{Binding}" />

</StackPanel>

</DataTemplate>

</xcdg:DataGridControl.Resources>

<xcdg:DataGridControl.Columns>

<xcdg:Column FieldName="One" Title="Title 1" TitleTemplate="{StaticResource ColumnTitleDataTemplate}" />

<xcdg:Column FieldName="Two" Title="Title 2"

TitleTemplate="{StaticResource ColumnTitleDataTemplate}" />

<xcdg:Column FieldName="Three" Title="Title 3"

TitleTemplate="{StaticResource ColumnTitleDataTemplate}" />

<xcdg:Column FieldName="Four" Title="Title 4"

TitleTemplate="{StaticResource ColumnTitleDataTemplate}" />

</xcdg:DataGridControl.Columns>

<xcdg:DataGridControl.View>

<xcdg:TableView ShowScrollTip="True"

UseDefaultHeadersFooters="False"

ShowRowSelectorPane="True"

ShowFixedColumnSplitter="True">

<xcdg:TableView.FixedHeaders>

<DataTemplate>

<xcdg:ColumnManagerRow />

</DataTemplate>

</xcdg:TableView.FixedHeaders>

</xcdg:TableView>

</xcdg:DataGridControl.View>

</xcdg:DataGridControl>

Figured it out...
