如何在停靠面板中添加兩個或更多按鈕？

Question

我正在使用WPF和DevExpress。我想在停靠面板中添加兩個按鈕。正如我添加第二個按鈕它說：Content is set more than once。爲什麼這樣？我犯了什麼錯誤，或者碼頭面板不允許這樣做。

<dxdo:DockLayoutManager Margin="0,-3,-156,0" HorizontalAlignment="Right" VerticalAlignment="Top" Background="White" Height="243" Width="109"> 
    <dxdo:LayoutGroup Caption="LayoutRoot" Margin="0,0,0,172"> 
     <dxdo:LayoutGroup Orientation="Vertical"> 
      <dxdo:LayoutPanel x:Name="Panel1" ShowCloseButton="False" ShowMaximizeButton="False" ShowPinButton="False" ShowRestoreButton="False" ShowControlBox="False" AllowDock="False" AllowDrag="False" AllowFloat="False" AllowHide="False" AllowClose="False" AllowActivate="False" AllowMinimize="False" AllowMaximize="False"> 
       <Button x:Name="ToggleButton1" Content="New" Click="ToggleButton_Click" HorizontalAlignment="Left" VerticalAlignment="Top"/> 
       <Button Content="Delete Focused Row" 
       Click="DeleteButton_Click33" 
       Grid.Column="1" /> 
      </dxdo:LayoutPanel> 
      <dxdo:LayoutPanel x:Name="Panel2" ShowCloseButton="False" ShowMaximizeButton="False" ShowPinButton="False" ShowRestoreButton="False" ShowControlBox="False" AllowDock="False" AllowDrag="False" AllowFloat="False" AllowHide="False" AllowClose="False" AllowActivate="False" AllowMinimize="False" AllowMaximize="False"> 
       <Button x:Name="ToggleButton2" Content="Close" Click="ToggleButton2_Click" HorizontalAlignment="Left" VerticalAlignment="Top"/> 
      </dxdo:LayoutPanel> 
     </dxdo:LayoutGroup> 
    </dxdo:LayoutGroup> 
</dxdo:DockLayoutManager> 

Answer 1

您可以將多個控件放入LayoutPanel.Content屬性中。只是包裝你的按鈕到面板：

<dxdo:LayoutPanel ... > 
    <StackPanel Orientation="Vertical"> 
     <Button x:Name="button1" ... /> 
     <Button x:Name="button2" ... /> 
    </StackPanel> 
</dxdo:LayoutPanel>
