如何保持菜单子菜单项打开？

I'm trying to create a somewhat complex menu item that would allow a user to create a new class. The problem into which I am running is that when I click on a numeric up-down ( from the xceed toolkit ) that the menu item closes, even with the property StaysOpenOnClick set to true.

我正在尝试创建一个有点复杂的菜单项,允许用户创建一个新类。我正在运行的问题是当我点击数字上下(从xceed工具包)菜单项关闭时,即使将属性StaysOpenOnClick设置为true。

Users will not like that.

用户不会喜欢这样。

To reproduce, create a WPF project and add the Extended WPF Toolkit through NuGet, then drop the following code into your mainwindow class :

要重现,创建一个WPF项目并通过NuGet添加Extended WPF Toolkit,然后将以下代码放入mainwindow类:

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:local="clr-namespace:WhyDoesMyMenuItemCloseWhenClicked"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
    mc:Ignorable="d"
    x:Class="WhyDoesMyMenuItemCloseWhenClicked.MainWindow"
    Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="21"/>
            <RowDefinition />
        </Grid.RowDefinitions>
        <Menu FontWeight="Bold">
            <MenuItem Header="_File">
                <MenuItem StaysOpenOnClick="True">
                    <Grid Height="50" Width="50">
                        <xctk:IntegerUpDown/>
                    </Grid>
                </MenuItem>
            </MenuItem>
        </Menu>
    </Grid>
</Window>

When I click the text field of the integer up-down, the menu closes.

当我单击上下整数的文本字段时,菜单将关闭。

Why does that keep happening? How can I make it NOT happen?

为什么会一直这样?怎么能让它不发生?

I have figured out a solution. It is sort of a terribly hacky workaround, but it does the job quite well :

我找到了解决方案。这是一种非常糟糕的解决方法,但它做得很好:

The change is that you create a MenuItem within the MenuItem. Then you define your control within the sub MenuItem's MenuItem.Header property, and set that MenuItem's StaysOpenOnClick property to true.

更改是您在MenuItem中创建MenuItem。然后在子MenuItem的MenuItem.Header属性中定义控件,并将MenuItem的StaysOpenOnClick属性设置为true。

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:local="clr-namespace:WhyDoesMyMenuItemCloseWhenClicked"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
    mc:Ignorable="d"
    x:Class="WhyDoesMyMenuItemCloseWhenClicked.MainWindow"
    Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="21"/>
            <RowDefinition />
        </Grid.RowDefinitions>
        <Menu FontWeight="Bold">
            <MenuItem Header="_File" StaysOpenOnClick="True">
                <MenuItem Header="_StaysOpenOnClick">
                    <MenuItem StaysOpenOnClick="True">
                        <MenuItem.Header>
                            <xctk:IntegerUpDown/>
                        </MenuItem.Header>
                    </MenuItem>
                </MenuItem>
            </MenuItem>
        </Menu>
    </Grid>
</Window>
