Ribbon ApplicationMenu AuxilaryPane大小

Question

如何在WPF Ribbon ApplicationMenu中更改AuxilaryPane的大小？我已经将最近的文件列表添加到该区域，但它正在被截断。理想情况下，我希望辅助窗格像Word/Excel一样充满屏幕。

我的代码：

<r:Ribbon.ApplicationMenu>
    <r:RibbonApplicationMenu>
        <r:RibbonApplicationMenu.AuxiliaryPaneContent>
            <StackPanel>
                <TextBlock Text="Recent Files" />
                <Separator />
                <ItemsControl ItemsSource="{Binding RecentFiles}">
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <r:RibbonApplicationMenuItem Header="{Binding ShortPath}" 
                                                         Command="{Binding DataContext.OpenRecentFileCommand, RelativeSource={RelativeSource AncestorType=ItemsControl}}"
                                                         CommandParameter="{Binding LongPath}"/>
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>
            </StackPanel>
        </r:RibbonApplicationMenu.AuxiliaryPaneContent>
    </r:RibbonApplicationMenu>                
</r:Ribbon.ApplicationMenu>

根据这个帖子中的答案，我发现对RibbonApplicationMenu进行子类并将第三列的宽度设置为Auto是最容易的。

 public class CustomRibbonApplicationMenu : System.Windows.Controls.Ribbon.RibbonApplicationMenu
    {
        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();

            System.Windows.DependencyObject obj = this.GetTemplateChild("PART_AuxiliaryPaneContentPresenter");

            System.Windows.Controls.ContentPresenter c = obj as System.Windows.Controls.ContentPresenter;

            ((System.Windows.Controls.Grid)((System.Windows.Controls.Border)c.Parent).Parent).ColumnDefinitions[2].Width = System.Windows.GridLength.Auto;
        }
    }

现在，您只需将Ribbon xaml从

<Ribbon.ApplicationMenu>
                <RibbonApplicationMenu>

至

<Ribbon.ApplicationMenu>
                <ctrl:CustomRibbonApplicationMenu>

如果你正在寻找一个非常快速的修复方法来增加高度，你可以简单地添加一些无用的RibbonApplicationMenuItems来填充盒子(而不需要修改MS源代码)。

​

            <ribbon:Ribbon.ApplicationMenu>
            <ribbon:RibbonApplicationMenu>
                <ribbon:RibbonApplicationMenu.Items>
                    <ribbon:RibbonApplicationMenuItem Name="saveSettings" Header="Save Settings" />
                    <ribbon:RibbonApplicationMenuItem IsEnabled="False"/> <!--USELESS-->
                    <ribbon:RibbonApplicationMenuItem IsEnabled="False"/> <!--USELESS-->
                </ribbon:RibbonApplicationMenu.Items>

                <ribbon:RibbonApplicationMenu.AuxiliaryPaneContent >
                        <StackPanel Orientation="Vertical" >
                            <GroupBox>
                                <Label Content="System Settings" />
                            </GroupBox>
                            <StackPanel Orientation="Horizontal">
                            </StackPanel>
                        </StackPanel>
                </ribbon:RibbonApplicationMenu.AuxiliaryPaneContent>
            </ribbon:RibbonApplicationMenu>
        </ribbon:Ribbon.ApplicationMenu>

我已经为同样的问题寻找了解决方案。

没有直接的属性来修改它。

创建此类属性的示例可在msdn中找到

以下是主要的解决方案：

更改功能区库的源代码。微软提供了功能库的源代码：http://www.microsoft.com/downloads/en/details.aspx?FamilyID=2bfc3187-74aa-4154-a670-76ef8bc2a0b4

下载源代码并将其打开，在MicrosoftRibbonForWPFSourceAndSamples\RibbonControlsLibrary\Microsoft\Windows\Controls\Ribbon\RibbonApplicationMenu.cs，中添加一个依赖属性：

    public double MinMenuHeight
    {
      get { return (double)GetValue(MinMenuHeightProperty); }
      set { SetValue(MinMenuHeightProperty, value); }
    }
    public static readonly DependencyProperty MinMenuHeightProperty =
        DependencyProperty.Register("MinMenuHeight", typeof(double), typeof(RibbonApplicationMenu), new UIPropertyMetadata(0.0));

在XAML行7519中，添加MicrosoftRibbonForWPFSourceAndSamples\RibbonControlsLibrary\Themes\Generic.xaml，代码：

    <Border x:Name="PopupBorder" MinHeight="{TemplateBinding MinMenuHeight}" BorderBrush="{Binding RelativeSource={RelativeSource AncestorType={x:Type ribbon:RibbonMenuButton}}, Path=Ribbon.BorderBrush}" Background="{Binding RelativeSource={RelativeSource AncestorType={x:Type ribbon:RibbonMenuButton}}, Path=Ribbon.Background}" BorderThickness="1" CornerRadius="2">
        <Grid>

        </Grid>
    </Border>

只添加给定xaml的前两行
