Issue with popup control within a document window

Hi,

I am opening a popup control on click of a button, but the elements within the popup window do not seem to get focussed.

XAMl -

<Window x:Class="DemoApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 xmlns:sd="clr-namespace:Divelements.SandDock;assembly=Divelements.SandDock"
        xmlns:local="clr-namespace:DemoApplication"
    Title="SandDock Demonstration Application" Width="1024" Height="768" SnapsToDevicePixels="True" WindowStartupLocation="CenterScreen"     >
    <sd:DockSite>

        <sd:DocumentContainer x:Name="documentContainer"  >

            <sd:SplitContainer>
                <sd:WindowGroup>
                    <sd:DocumentWindow  Title="Welcome" Name="welcomeDocument" >
                        <Grid>
                            <StackPanel>
                                <TextBox></TextBox>
                                <Button   Click="Button_Click">Lookup</Button>

                                <Popup x:Name="popup" Placement="MousePoint"    StaysOpen="False" >
                                    <sd:DockableWindow x:Name="test"   Title="EM" >

        <StackPanel >
            <CheckBox Grid.Column="0" Grid.Row="0" Margin="8"  Width="20" x:Name="chk" ></CheckBox>
            <TextBox Grid.Row="0" Grid.Column="1" Margin="5" Width="50" ></TextBox>
                        <TextBox Grid.Row="0" Grid.Column="2" Margin="5" Width="50"></TextBox>
                   </StackPanel>   

                       
                   
                </sd:DockableWindow>

                                </Popup>

                            </StackPanel>
                        </Grid>
                    </sd:DocumentWindow>
                </sd:WindowGroup>
            </sd:SplitContainer>
        </sd:DocumentContainer>
    </sd:DockSite>
</Window>

As you can see the popup contains a textbox and checkbox. The checkbox never seems to retain focus.

Why are you embedding a dockableWindow Within a popup ? Placing your controls inside a popup control is sufficient enough to do what you want

If you try with this code then its fine (at least for me...)

<

Window x:Class="popupInsideDocumentWindow.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x

xmlns:sd="clr-namespace:Divelements.SandDock;assembly=Divelements.SandDock"

Sorry for the horrible layout, there is now way to edit my post back so....
