UWP模板10创建动态汉堡包菜单 [英] UWP Template 10 create a dynamic hamburgermenu

问题描述

我对UWP的东西很了解.我正在尝试创建动态汉堡包菜单. 我能够创建PrimaryButtons元素，并按照预期将其绑定到XAML中:

I'm pretty noob with UWP stuff. I'm trying to create dynamic hamburger menu. I was able to create PrimaryButtons element, and binding it in XAML worked as espected:

var loginButton = new HamburgerButtonInfo();
loginButton.ClearHistory = true;
loginButton.PageParameter = "";
loginButton.PageType = typeof(Views.Login);
var stackPanel = new StackPanel { Orientation = Orientation.Horizontal };
stackPanel.Children.Add(new SymbolIcon { Symbol = Symbol.Contact, Width = 48, Height = 48 });
stackPanel.Children.Add(new TextBlock { Text = "Login", VerticalAlignment = VerticalAlignment.Center, Margin = new Thickness(12, 0, 0, 0) });
loginButton.Content = stackPanel;

但是我想有一个更干净的解决方案，所以我尝试扩展HamburgerButtonInfo类:

But I'd like to have a cleaner solution, so I tried to extend HamburgerButtonInfo class:

class MenuItem : HamburgerButtonInfo
{
    private Symbol symbol;
    private String text;
    StackPanel stackpanel = new StackPanel { Orientation = Orientation.Horizontal };
    TextBox textbox = new TextBox { VerticalAlignment = VerticalAlignment.Center, Margin = new Thickness(12, 0, 0, 0) };
    SymbolIcon symbolicon = new SymbolIcon { Width = 48, Height = 48 };

    public MenuItem():base()
    {
        StackPanel.Children.Add(symbolicon);
        StackPanel.Children.Add(textbox);
        this.Content = StackPanel;
    }

    public String Text
    {
        get { return text; }
        set {
            textbox.Text = value;
            Set(ref text, value);
        }
    }

    public StackPanel StackPanel
    {
        get { return stackpanel; }
    }

    public Symbol Symbol
    {
        get { return symbol; }
        set {
            symbolicon.Symbol = value;
            Set(ref symbol, value);
        }
    }
}

将所有内容放在一起，我希望得到相同的结果:

Putting it all together, I expected to get the same result:

PrimaryButtons.Add(loginButton);
PrimaryButtons.Add(new MenuItem() { PageType=typeof(Views.Login), PageParameter="", ClearHistory=true, Text="Login", Symbol=Symbol.Contact });

但这是结果

我错过了什么吗?对于这种情况，这是正确的方法吗?

Am I missing something? Is that the right approach for this scenario?

推荐答案

可以做到吗?绝对.

var stackPanel = new StackPanel
{
    Orientation = Orientation.Horizontal
};
stackPanel.Children.Add(new SymbolIcon
{
    Width = 48,
    Height = 48,
    Symbol = Symbol.UnSyncFolder
});
stackPanel.Children.Add(new TextBlock
{
    Margin = new Thickness(12, 0, 0, 0),
    VerticalAlignment = VerticalAlignment.Center,
    Text = "UnSync Folder"
});
var button = new HamburgerButtonInfo
{
    Content = stackPanel,
    ButtonType = HamburgerButtonInfo.ButtonTypes.Toggle,
    ClearHistory = false,
    PageType = typeof(Views.DetailPage)
};
MyHamburgerMenu.PrimaryButtons.Add(button);

看起来像这样(我在搜索"示例中尝试过).

Looks like this (I tried it in the Search sample).

它更为冗长，因为XAML语法非常紧凑，但是您可以根据需要在代码隐藏中进行操作.如果可以的话，您可能只想更改现有按钮的可见性.

It's more verbose because the XAML syntax is so compact, but you can do it in code-behind if you want to. You might just want to change visibility of an existing button if that is an option.

祝你好运！
