wpf Xaml:如何将自定义类公开给DataTemplate [英] wpf Xaml :how to expose custome class to DataTemplate

问题描述

我有一个用作数据源的类

I have a class which used as DataSource

namespace DictMainUI.Model
{
    class SearchListItem:INotifyPropertyChanged
    {
        private string word;
        private int checkamount;
        ............
        public string Word
        {
            get { return this.word; }
            set
            {
                this.word = value;
                OnPropertyChanged(Word);
            }
        }
        public int CheckAmount
        {
            get { return this.checkamount; }
            set
            {
                if (value < 0)
                {
                    throw new ArgumentException("Price must be positive");
                }
                this.checkamount = value;
                OnPropertyChanged("CheckAmount");
            }
        }
.............

我想为要绑定到SearchListItem的ListboxItem定义一个日期模板.

我有一个ResourceDictionary，我想在此资源中定义DataTemplate.

I want to define a datetemplate for ListboxItem that I want to bind to SearchListItem.

I have a ResourceDictionary, I want to define DataTemplate in this resource.

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                   
                    >

所以我认为我应该添加名称空间，以便向此ResourceDictionary公开SearchListItem属性.但是一旦我将其添加到resourcedictionary中，构建项目就失败了，没有任何消息，并且在运行它时，它显示了错误，提示:设置输出和程序集名称正确或如下所示的.code之类的代码(如我所说，显示错误)

so I think I should add namespace to in order to expose SearchListItem attributes to this ResourceDictionary. but once I add it to the resourcedictionary , building project is failed without any message, and when run it, it shows error it says:set output and assembly name correct or something like that .code shown below (which show error as I said)

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                   xmlns:src="clr-namespace:DictMainUI.Model"
                    >

将DictMainUI.Model命名空间添加到ResourceDictionary时出错.

我不知道为什么它不起作用，有人在这个问题上给我提建议吗?

it got wrong when I add DictMainUI.Model namespace to the ResourceDictionary.

I did not know why it dose not work,is there anyone give me a advice on that problem?

thanks in advance!

推荐答案

如果namespace在另一个程序集中，则还必须提供该程序集的名称，如下所示:

If the namespace is in another assembly, you have to provide the assembly''s name too, like the following:

<ResourceDictionary

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:src="clr-namespace:DictMainUI.Model;assembly=DictMainUI.Model"

                    >

我不知道项目发生了什么，经过多次修复后，我放弃了该项目，并构建了一个新项目并映射了custome类到资源词典y正在为此工作.

I don''t know what happened to the project, after tried to fix it many times I give up on that project , and build whole new project and mapping custome class to resourcedictionary is worked on this one.
