如何访问控制在WPF XAML参考？ [英] How to access to control references in WPF Xaml?

问题描述

我有一些控制，我设置其名称属性唯一的名称，但我无法访问它们对应的C＃code文件。

我曾尝试：

  this.ControlName
MainWindow.ControlName
控件名称
 

但它确实看见他们。

我如何做到这一点？

还做我必须做一些特别的包装板，网格的意见，等等？

里面嵌套控制

解决方案

有关访问任何元素在code背后，你需要设置X：名称指令。 它告诉XAML解析器添加一个字段重新$ P $指定元素psenting到Window类一样的WinForms的自动生成的部分。

在一个WPF应用程序，也没有要求每个元素名称。您应该名存实亡要以编程方式进行交互这些元素。

一个例子：

 ＆LT; TextBlock的X：名称=tblText文本=＃1石头＆GT;＆LT; / TextBlock的＆GT;

    ///＆LT; /总结＆gt;
    公共部分类窗口1：窗口
    {
        公共窗口1（）
        {
            的InitializeComponent（）;
            EffectsListView.Width = 10;
        }
    }
}

＆LT;窗​​口x：类=WpfApplicationUnleashed.Window1

        的xmlns：SYS =CLR的命名空间：系统;装配= mscorlib程序
        XMLNS：地方=CLR的命名空间：WpfApplicationUnleashed
        标题=窗口1＆GT;
    ＆LT; D​​ockPanel中＆GT;
        ＆LT; ListView的X：名称=EffectsListView＆GT;＆LT; / ListView控件＆GT;
    ＆LT; / DockPanel中＆GT;
＆LT; /窗＆GT;
 

I have some controls where I set their Name property to unique names, but I am unable to access them in the matching C# code file.

I have tried:

this.ControlName
MainWindow.ControlName
ControlName

but it does "see" them.

How do I do this?

Also do I have to do something special for nested controls inside wrap panels, grid views, etc?

解决方案

For accessing any element in code behind you will need to set x:Name directive. It tells the XAML parser to add a field representing the named element to the automatically generated portion of the Window class just like Winforms.

In a WPF application, there’s no requirement to name each and every element. You should name only those elements which you want to programatically interact with.

An example:

<TextBlock x:Name="tblText" Text="Stackoverflow rocks."></TextBlock>

EDIT:
I used the following code and I was able to access the

namespace WpfApplicationUnleashed
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {    
        public Window1()
        {
            InitializeComponent();
            EffectsListView.Width = 10;
        }    
    }
}

<Window x:Class="WpfApplicationUnleashed.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        xmlns:local="clr-namespace:WpfApplicationUnleashed"
        Title="Window1" >
    <DockPanel>
        <ListView x:Name="EffectsListView"></ListView>
    </DockPanel>
</Window>
