在 AvalonDock 中，我們使用 LayoutDocumentExtended 在 Title 中添加一些 AdditionalInformation（不僅僅是我們專案中的字串）。
在此測驗代碼中，我們將 DocumentHeaderTemplate 設定如下。
<xcad:DockingManager.DocumentHeaderTemplate>
<DataTemplate DataType="{x:Type local:LayoutDocumentExtended}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Title, StringFormat={}{0} ---- }" />
<TextBlock Text="{Binding AdditionalString}" />
</StackPanel>
</DataTemplate>
</xcad:DockingManager.DocumentHeaderTemplate>
<xcad:LayoutRoot>
<xcad:LayoutPanel Orientation="Vertical" >
<xcad:LayoutDocumentPane>
<xcad:LayoutDocumentPane.Children>
<local:LayoutDocumentExtended Title="Test1" AdditionalString="848451"> </local:LayoutDocumentExtended>
<local:LayoutDocumentExtended Title="Test2" AdditionalString="1"></local:LayoutDocumentExtended>
</xcad:LayoutDocumentPane.Children>
</xcad:LayoutDocumentPane>
</xcad:LayoutPanel>
</xcad:LayoutRoot>
如果我將 LayoutDocument 取消停靠為 FloatingWindow，則僅顯示標題而不顯示 AdditionalString。一旦我再次重新停靠它，就會再次顯示 AdditionalString。有人知道如何在 FloatingWindows 上設定可配置的 DocumentHeaderTemplate 嗎？
uj5u.com熱心網友回復：
該LayoutDocumentFloatingWindowControl控制元件使用WindowChrome來定義標題欄。您可能想要修改 chrome 的標題欄以允許它顯示額外的垂直內容，即額外的行。或者，考慮在括號中和同一行中顯示額外資訊。
覆寫DocumentTitleTemplate以布局標題：
<DataTemplate x:Key="DocumentTitleTemplate">
<TextBlock Text="{Binding Title}"
TextTrimming="CharacterEllipsis">
</TextBlock>
</DataTemplate>
覆寫LayoutDocumentFloatingWindowControl樣式以修改標題欄高度：
