在ToolBarTray中设置工具栏之间的间距
我的ToolBarTray里面有多个ToolBar。我的目标是将所有这些工具栏与垂直线分开。
目前，我已经对ToolBar类进行了细分，并以编程方式使工具栏的边框非圆角（默认边框有圆角）。但是，我无法摆脱工具栏之间的这种间距。
我完全可以删除ToolBarTray，而是使用Grid或StackPanel来实现这一点。但是，我需要保留工具栏可以拖动/重新安排的能力。
这有什么简单的解决方案吗？

<Grid>
<ToolBarTray x:Name="ToolTray" Grid.Row="0" Grid.RowSpan="2" Background="SkyBlue">
<ToolBar Band="0" BandIndex="0" Style="{DynamicResource ToolBarStyle1}">
<Button Background="Aqua" Height="25" Width="25" Content="0" />
<Button Background="BlueViolet" Height="25" Width="25" Content="0" />
<Button Background="CornflowerBlue" Height="25" Width="25" Content="0"/>
</ToolBar>
<ToolBar Band="0" BandIndex="1" Style="{DynamicResource ToolBarStyle1}">
<Button Background="Aqua" Height="25" Width="25" Content="1"/>
<Button Background="BlueViolet" Height="25" Width="25" Content="1"/>
<Button Background="CornflowerBlue" Height="25" Width="25" Content="1"/>
</ToolBar>
</ToolBarTray>
</Grid>
答案 1 :(得分：-1)
根据Joby的回答，我想出了一个替代方案。希望这可以在以后的某个时间帮助别人。两种方法基本上都做同样的事情，但它们的实现方式不同。根据不同的情况，使用两者中的特定一个可能更合适。
原始答案的关键部分是更改Grid中的Template元素，以使右边距为-3（以抵消3的左边距）。
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToolBar}">
<Grid x:Name="Grid" Margin="3,1,-3,1" ...
...
在不重新定义整个模板的情况下执行此操作的替代方法是子类ToolBar class：
class MyToolBar : ToolBar
{
public NoOverflowToolBar()
: base()
{
this.Loaded += MyToolBar_Loaded;
}
void MyToolBar_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
ToolBar toolBar = sender as ToolBar;
var grid = toolBar.Template.FindName("Grid", toolBar) as FrameworkElement;
if (grid != null)
{
grid.Margin = new Thickness(3, 1, -3, 1);
}
}
}
更新
在编写自定义控件方面有一些经验之后，我意识到没有必要使用Loaded事件来编写它 - 只需使用OnApplyTemplate()覆盖。
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
var grid = this.Template.FindName("Grid", this) as FrameworkElement;
if (grid != null)
{
grid.Margin = new Thickness(3, 1, -3, 1);
}
}
