键盘导航 - 使用Tab键浏览控件

Question

我搜索了堆栈溢出，然而，我无法找到任何解决方案。我认为问题来自定制控件或我做错了什么。我使用了一个名为＆＃34; Dragablz＆＃34;的自定义TabControl。每当我尝试使用＆＃39; Tab＆＃39;键盘上的键，它似乎继续TabItems，TabControl背景等。我想实现只通过当前选定的TabItem（按钮，组合框等）的网格内的控件进行导航。

这是代码

<Tool:DialogHost x:Name="RDialog" Loaded="OnRootDialog_Loaded" Identifier="RootDialog">
    <Dock:Layout>
        <Dbz:TabablzControl x:Name="TabControl" TextElement.Foreground="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=Window}, Path=(TextElement.Foreground)}" Background="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=Window}, Path=Background}">
            <TabItem Header="DEVICE" x:Name="tabItemDevice">
                <Grid>
                    <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
                        <ComboBox x:Name="cmbDevice" Width="300" FontSize="15" Tool:TextFieldAssist.Hint="Select Device:" SelectionChanged="OnDeviceComboBox_SelectionChanged"/>
                        <ComboBox x:Name="cmbAddress" Width="150" FontSize="15" Margin="30" Tool:TextFieldAssist.Hint="Select Address:" SelectionChanged="OnDeviceComboBox_SelectionChanged"/>
                    </StackPanel>

                    <Button x:Name="btnStartStop" Content="_START" VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="0 0 -4 -5" Click="OnDeviceButton_Click"/>
                    <Button x:Name="btnConfigureDevice" Content="_CONFIGURE DEVICE" VerticalAlignment="Bottom" HorizontalAlignment="Left" Margin="-3 0 0 -5" Click="OnDeviceButton_Click"/>
                </Grid>
            </TabItem>
            <TabItem Header="PHONEBOOK" x:Name="tabItemPhonebook">
                <Grid>
                    <StackPanel Margin="-6" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center">
                        <Button TabIndex="2" x:Name="btnNewClient" Content="_NEW CLIENT" VerticalAlignment="Bottom" HorizontalAlignment="Left" Click="OnPhonebookButton_Click"/>
                        <Button TabIndex="1" Margin="10 0 0 0" x:Name="btnOpenPhonebook" Content="_OPEN PHONEBOOK" VerticalAlignment="Bottom" HorizontalAlignment="Left" Click="OnPhonebookButton_Click"/>
                    </StackPanel>
                </Grid>
            </TabItem>
            <TabItem Header="MANAGE CALLS" x:Name="tabItemManageCall">
                <Grid>
                    <StackPanel Margin="-6" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center">
                        <Button TabIndex="3" x:Name="btnCallRecord" Content="_CALL RECORDS" VerticalAlignment="Bottom" HorizontalAlignment="Right" Click="OnManageCallsButton_Click"/>
                        <Button TabIndex="4" x:Name="btnDial" Margin="10 0 0 0" Content="_DIAL" VerticalAlignment="Bottom" HorizontalAlignment="Right" Click="OnManageCallsButton_Click"/>
                    </StackPanel>
                </Grid>
            </TabItem>
            <TabItem Header="SETTINGS" x:Name="tabItemSetting">
                <Grid>
                    <StackPanel Margin="-6" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center">
                        <Button x:Name="btnApplicationSetting" Content="APPLICATION SETTINGS"/>
                        <Button x:Name="btnContactMe" Content="CONTACT ME" Margin="10 0 0 0" Click="OnSettingsButton_Click"/>
                    </StackPanel>
                </Grid>
            </TabItem>
        </Dbz:TabablzControl>
    </Dock:Layout>
</Tool:DialogHost>

我尝试过使用以下内容; KeyboardNavigation.TabNavigation="Cycle" KeyboardNavigation.IsTabStop="False"

不幸的是，它没有工作，它仍然通过标签项，我只想在TabItem控件内导航。

谢谢！

解决方法我成功了;

private void OnMainWindow_KeyDown(object Sender, KeyEventArgs e)
    {
        if(e.Key == Key.Tab)
        {
            e.Handled = true;

            if (TabControl.SelectedIndex == 0) /* Device */
            {
                if(!cmbDevice.IsFocused || !cmbAddress.IsFocused
                    || btnConfigureDevice.IsFocused || btnStartStop.IsFocused)
                {
                    cmbDevice.Focus();
                }
                else if (cmbDevice.IsFocused)
                {
                    cmbAddress.Focus();
                }
                else if (cmbAddress.IsFocused)
                {
                    btnConfigureDevice.Focus();
                }
                else if (btnConfigureDevice.IsFocused)
                {
                    btnStartStop.Focus();
                }
                else if (btnStartStop.IsFocused)
                {
                    cmbDevice.Focus();
                }
            }
        }
    }
