                                    </i:EventTrigger>

                                <datagrid:ThemedDataGrid.Columns>
                                    <DataGridCheckBoxColumn  Binding="{Binding CurrentIstZuStand, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay }"  Header="{DynamicResource IstZustand}" />

                                </datagrid:ThemedDataGrid.Columns>
                            </datagrid:ThemedDataGrid>
                        </DockPanel>
                    </docking:ToolWindow>

                    <toolWindows:PropertyGridToolWindow Title="{DynamicResource Properties}" CanClose="False" HasOptions="False" TabBackground="White"/>

                    <toolWindows:ToolWindowView Title="{DynamicResource AllMessages}" CanClose="False" HasOptions="False" TabBackground="White"/>

                    <toolWindows:CreateInstrumentsToolWindow Title="{DynamicResource CreateInstruments}" />
                </docking:ToolWindowContainer>
            </docking:DockSite.AutoHideRightContainers>

 In CodedUiTest i activate one tab and can get all ToolWindows from container f.e. with GetChildren(), but they all are invisible. The activated tab is not visible too. If i try to reach an element from toolwindow i get exception. Depends that on the settings of DockSite/ToolWindow or is there another reason for that?
