When TabItem loses focus, all controls on TabItem GET focus

[C Bates]

Hello,

I have put together a simple app to demonstrate the problem.  I have a RadTabItem with several TextBox controls on it.

If I:

- click in a TextBox

- click on another tab header in the same group

All the TextBox controls on the first TabItem receive a "GotFocus" event.

Very undesirable, since every time certain controls in our real application gets focus it initiates a round-trip to the server.

The xaml:

        <dock:RadDocking x:Name="docking" Grid.Row="1">
            <dock:RadDocking.DocumentHost>
                <dock:RadSplitContainer x:Name="mapContainer1">
                    <dock:RadPaneGroup x:Name="leftGroup" GotFocus="Group_GotFocus">
                        <dock:RadPane x:Name="leftPane" GotFocus="Pane_GotFocus">
                            <tab:RadTabControl x:Name="leftTabControl"  GotFocus="TabControl_GotFocus" >
                                <tab:RadTabItem Header="tab1" GotFocus="RadTabItem_GotFocus">
                                    <StackPanel>
                                        <TextBox x:Name="tb1" Text="tb1"  GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb2" Text="tb2" GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb3" Text="tb3"  GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb4" Text="tb4" GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb5" Text="tb5" GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb6" Text="tb6" GotFocus="TextBox_GotFocus" />
                                    </StackPanel>
                                </tab:RadTabItem>
                                <tab:RadTabItem Header="tab2" GotFocus="RadTabItem_GotFocus">
                                    <StackPanel>
                                        <TextBox x:Name="tb7" Text="tb7" GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb8" Text="tb8" GotFocus="TextBox_GotFocus" />
                                        <TextBox x:Name="tb9" Text="tb9" GotFocus="TextBox_GotFocus" />
                                    </StackPanel>
                                </tab:RadTabItem>
                            </tab:RadTabControl>
                        </dock:RadPane>
                    </dock:RadPaneGroup>
                </dock:RadSplitContainer>
            </dock:RadDocking.DocumentHost>
        </dock:RadDocking>

Is this a bug?  Is there a work-around?

Thanks.

(In the screenshot, I started the app, clicked on tb1, then clicked on tab2.  tb1 - tb6 received GotFocus events.)

Update:  If I click on tb1, then click on tab1 (does nothing, since tab1 is already the selected tab), then click on tab2, tb1 - tb6  _don't_ get all the GotFocus events.  Weird.
