如何正确地引用来自XAML类 [英] How to properly reference a class from XAML

问题描述

OK，这是一个超级超级noob问题，一个我几乎不好意思问...

OK, this is a super super noob question, one that I'm almost embarrassed to ask...

我想在我的XAML文件中引用类。它是选择一个DataGrid列右侧的修改模板DataTemplateSelector。

I want to reference a class in my XAML file. It's a DataTemplateSelector for selecting the right edit template for a DataGrid column.

不管怎样，我已经写了类到我后面的代码，添加了本地命名空间的顶部在XAML之上，但是当我尝试从XAML引用类，它告诉我的班在当地的命名空间不存在。我必须失去了一些东西真的很简单，但我只是不明白它...

Anyway, I've written the class into my code behind, added the local namespace to the top of top of the XAML, but when I try to reference the class from the XAML, it tells me the class does not exist in the local namespace. I must be missing something really really simple but I just can't understand it...

下面是我的代码。

XAML：

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit"
xmlns:local="clr-namespace:CustomFields"
xmlns:col="clr-namespace:System.Collections;assembly=mscorlib"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
x:Class="CustomFields.MainWindow"
x:Name="Window"
Title="Define Custom Fields"
Width="425" Height="400" MinWidth="425" MinHeight="400">

<Window.Resources>
    <ResourceDictionary>
        <local:RangeValuesEditTemplateSelector>
            blah blah blah...
        </local:RangeValuesEditTemplateSelector>
    </ResourceDictionary>
</Window.Resources>

C＃：

C#:

namespace CustomFields
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.InitializeComponent();

            // Insert code required on object creation below this point.
        }
    }

    public class RangeValuesEditTemplateSelector : DataTemplateSelector
    {
        public RangeValuesEditTemplateSelector(){

            MessageBox.Show("hello");
        }
    }   
}

任何想法我做错了什么？我想这应该是简单的1-2-3 ...

Any ideas what I'm doing wrong? I thought this should be simple as 1-2-3...

谢谢！
