我有一個Expander右鍵展開方向。這工作正常，但我希望內容仍然出現在擴展器按鈕和標題下。另外我想讓這些按鈕和標題仍然出現在同一行上。這樣做的最好方法是什麼？帶有默認標題的擴展方向右鍵
<Expander Header="Test" ExpandDirection="Right">
<ListBox VerticalAlignment="Top" MaxHeight="400" Name="lbxTest"/>
</Expander>
您需要重新模板整個Expander控件。您可以在Expander設計模式在Visual Studio或混合右鍵單擊並選擇編輯模板 - >編輯複製到默認模板它複製到你的XAML標記，然後編輯按您的要求：
<Expander Header="Test" ExpandDirection="Right">

沒有，還有就是做這個:)
This is a bit of Trick but can be done as under :
<Expander Header="Test" ExpandDirection="Right">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="25"/>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Button Content="Test" Grid.Row="1" Margin="-25,20,0,0" Height="25" Width="50" HorizontalAlignment="Left"/>
</Grid>
</Expander>
You need to give a negative margin for the left portion value.
Also you have to give margin for the top portion so that the header for the expander gets visible.
標題測試仍然出現在Expander按鈕下面的行上：/ – windowskm
您可以使用Margin =「35，-30,0,0」作爲Button查看標題右側的按鈕。 –
如果你「想有內容仍然出現在擴展按鈕和標題下」，你爲什麼然後設置ExpandDirection爲右沒有更簡單的方法？ – mm8
請查看下面的答案以獲得更簡單的版本。 –
聽起來好像您只需要一個正常的擴展器，它是左對齊的，並且在擴展時會在寬度和高度上增長。 – grek40
