Question

我在底座上有一个telerik关闭按钮，我希望覆盖它的样式，以允许用户选择他们想要关闭的内容。

以Notepad ++为例..有一个“关闭”和一个“关闭所有这个”选项。

这正是我想用这个telerik radDock关闭按钮做的事情。

我研究了这个，找不到任何有用的东西让我真正开始。我刚开始使用WPF（实际上是C＃），所以任何有用的建议，代码或示例项目都将受到赞赏。先谢谢你。

Metro Smurf，它与此时的教程非常相似。我对WPF和C＃都很陌生，所以请你好好哈哈。

这是我的XAML：

Answer 1

根据您的代码，您几乎就在那里。

<Window x:Class="RadDockCloseButton1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:local="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"
        Title="MainWindow" Height="350" Width="525">

应该（注意local命名空间）：

<Window x:Class="RadDockCloseButton1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:local="clr-namespace:RadDockCloseButton1"
        Title="MainWindow" Height="350" Width="525">

local命名空间指的是哪个类具有自定义命令。在这种情况下，您已将该类添加到RadDockCloseButton1命名空间。

在构造函数中注册命令：

public MainWindow()
{
    InitializeComponent();

    CommandManager.RegisterClassCommandBinding(
    typeof( RadPaneGroup ),
    new CommandBinding(
        RadDockingCommands.CloseAllPanesButThisCommand,
        RadDockingCommands.OnCloseAllPanesButThis,
        RadDockingCommands.OnCloseAllPanesButThisCanExecute ) );
}

移动public static class RadDockingCommands类，使其不嵌套在MainWindow内。即。

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        CommandManager.RegisterClassCommandBinding(
                typeof( RadPaneGroup ),
                new CommandBinding(
                        RadDockingCommands.CloseAllPanesButThisCommand,
                        RadDockingCommands.OnCloseAllPanesButThis,
                        RadDockingCommands.OnCloseAllPanesButThisCanExecute ) );
    }
}

public static class RadDockingCommands
{
    private static RoutedUICommand closeAllPanesButThisCommand;

    // etc...
}

最后，用几个窗格进行测试。要么为样本添加其他窗格，要么只使用它：

<telerik:RadDocking>
    <telerik:RadDocking.DocumentHost>
        <telerik:RadSplitContainer>
            <telerik:RadPaneGroup>
                <telerik:RadPane Header="Pane 1" />
                <telerik:RadPane Header="Pane 2" />
                <telerik:RadPane Header="Pane 3" />
                <telerik:RadPane Header="Pane 4" />
                <telerik:RadPane Header="Pane 5" />
            </telerik:RadPaneGroup>
        </telerik:RadSplitContainer>
    </telerik:RadDocking.DocumentHost>
</telerik:RadDocking>

如果这仍然不适合您，我会发布整个工作样本。
