WPF Control Background under GridViewColumn

Question

Hi,

I'd like make background for colums like in this image http://www.freeimagehosting.net/image.php?e2435df982.png

I have CheckBoxes on the left and TreeView on the right. In one column I have checkboxes in other I have treeview. In column with checkboxes I need set background. Background has to be permanent.

....

                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>

                   <GridViewColumn Width="25">   All column has to have background not only cell
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <CheckBox>
                                    <CheckBox.Resources>
                                        <ResourceDictionary>
                                            <ResourceDictionary.MergedDictionaries>
                                                ....
                                            </ResourceDictionary.MergedDictionaries>
                                        </ResourceDictionary>
                                    </CheckBox.Resources>
                                </CheckBox>

                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>                       
                    </GridViewColumn>
                    <GridViewColumn Width="300"/>
                </TreeListView.Columns>
                <TreeListView.Resources>
                    <ResourceDictionary>
                        <ResourceDictionary.MergedDictionaries>
                           ... TreeView.xaml
                        </ResourceDictionary.MergedDictionaries>
                    </ResourceDictionary>
                </TreeListView.Resources>
                <TreeListView.ItemTemplate>
                    <HierarchicalDataTemplate>
                        <HierarchicalDataTemplate.ItemsSource>
                            ....
                        </HierarchicalDataTemplate.ItemsSource>
                    </HierarchicalDataTemplate>
                </TreeListView.ItemTemplate>
            </TreeListView>
