C# 密钥提示在Microsoft Ribbon中不起作用

使用RibbonControlsLibrary（3.5.41019.1）时，“钥匙头”工作不正常。我创建了一个简单的RibbonWindow：

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>

添加几个选项卡

添加一些控件，如按钮

设置标签和标题等属性

在选项卡上设置KeyTip属性

我在desgin模式（VS2010）下测试了KeyTip，一切正常。但是，当我将项目构建为windows应用程序时，会出现以下情况：

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>

• ALT+KeyTip仅显示按键提示，焦点不改变。预期的行为将是改变标签

我试图创建一个干净的wpfribbon项目，并做了同样的事情，然后出于某种原因，它工作了。非工作项目是表单和WPF的混合体，表单显示在WPF窗口之前。这可能是问题所在吗？我明白为什么这会是个问题了

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>

源代码：

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>

在功能区控件中添加属性：KeyboardNavigation.ControlTabNavigation

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>

 <ribbon:Ribbon DockPanel.Dock="Top" SelectedIndex="1" KeyboardNavigation.ControlTabNavigation="Contained">

它对我有效。

在显示WPF窗口之前，我通过添加以下代码行成功解决了问题：

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>

System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(this);

如果在同一项目中混合使用WinForms和WPF窗口，则至少当WinForm显示在WPF窗口之前时，这是必需的

        <ribbon:RibbonTab x:Name="HomeTab" 
                          Header="Home" KeyTip="H">
            <ribbon:RibbonGroup x:Name="Group1" 
                                Header="Group1">
                <ribbon:RibbonButton Label="Hej" KeyTip="T" />                    
            </ribbon:RibbonGroup>

        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab1">
            <ribbon:RibbonGroup Header="Min grupp">
                <ribbon:RibbonButton Label="Test" />
                <ribbon:RibbonSplitButton Label="Testen">
                    <ribbon:RibbonMenuItem Header="Jaha" />
                </ribbon:RibbonSplitButton>
            </ribbon:RibbonGroup>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Tab2" KeyTip="2" />
        <ribbon:RibbonTab Header="Tab3" KeyTip="3" />
</ribbon:Ribbon>
