在WPF中重构XAML [英] Refactor XAML in WPF

问题描述

我的XAML已经很长，很难维护。

My XAML has got very long and hard to maintain. I was wondering if there is a way to do something like refactoring?

这里有一个简单的例子：

Here is a simple example:

<Window x:Class="RefactorXAML.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <StackPanel>
            <Button>New</Button>
            <Button>Open</Button>
        </StackPanel>
    </Grid>
</Window>

如何重构 Stackpanel 写这样？

<Window x:Class="RefactorXAML.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        // Refactored Markup
    </Grid>
</Window>

推荐答案

您可以将这些按钮放在用户控件中，使它像这样：

You could put those buttons in a user control, to make it like this:

<Window …
        xmlns:my="clr-namespace:SomeNamespace">
    <Grid>
        <my:NewAndOpenButtons />
    </Grid>
</Window>

您还可以用已经包含这些按钮的项目控件替换网格，

You could also replace the grid by an items control which already includes those buttons, but that way you would impose too many restrictions on the other content, so I wouldn’t do that.

所以对于上面的内容，你的用户控件看起来像这样：

So for the above, your user control would look something like this:

<UserControl x:Class="SomeNamespace.NewAndOpenButtons" …>
    <StackPanel>
        <Button>New</Button>
        <Button>Open</Button>
    </StackPanel>
</UserControl>
