如何在同一个库中拥有多个 wpf 自定义控件? [英] how to have many wpf custom controls in the same library?

问题描述

我有一个 WPF 自定义控件项目，我想在其中包含许多自定义控件.默认情况下，VS2015 cummunity 创建一个 Theme 文件夹，其中包含一个 generic.xaml 文件和一个包含交互逻辑的 .cs 文件.

I have a WPF custom control project in which I want to have many custom controls. By default, VS2015 cummunity creates a Theme folder with a generic.xaml file and a .cs file with the interaction logic.

我想要很多用户控件，所以我尝试创建一个 MyControl1 文件夹，在这个文件夹中，我创建了一个 Theme 文件夹并添加了一个新项目，一个 WPF 自定义控件.但它不会为此控件创建 generic.xaml.我从根文件夹复制了默认的 generic.xaml 并创建了我的样式，但是当我在我的 WPF 应用程序中使用该控件时，我没有看到该控件.

I want to have many user controls, so I have tried to create a MyControl1 folder, inside this folder, I have created a Theme folder and I add a new item, a WPF custom control. But it doesn't create a generic.xaml for this control. I copy from the root folder the default generic.xaml and I create my style, but when I use the control in my WPF application, I don't see the control.

我看过这篇文章:自定义控件库与多个control 和 generic.xaml 但我真的不太了解解决方案.

I have seen this post: Custom control Lib with multiple controls and generic.xaml but really I don't understand so much the solution.

我有一个问题，在 MyControl1.Generic.xaml 中有这个代码:

I have a problem, in MyControl1.Generic.xaml y have this code:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:CustomControls.Calendario2">


    <Style TargetType="{x:Type local:CalendarioMes2}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:CalendarioMes2}">
                    <Border Background="{TemplateBinding Background}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="{TemplateBinding BorderThickness}">

                        <Grid>
                            <TextBox Text="Prueba"/>
                            <Label Content="Prueba"/>
                        </Grid>

                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

但我在这一行中遇到错误:

But I get an error in this line:

<Style TargetType="{x:Type local:CalendarioMes2}">

无法从文本 local:CalendarioMes2 创建类型.

That it is not possible to create a type from text local:CalendarioMes2.

如果我在只有一个自定义控件的库中使用此代码并且此代码位于 generic.xaml 文件中，则它可以工作.

If I use this code in a library with only one custom control and this code is in the generic.xaml file, it works.

所以，总而言之，我想知道如何拥有一个包含许多自定义控件的库.

So, in sumary, I would like to know how could I have a library with many custom controls.

谢谢.

推荐答案

我发现最简洁的方法是创建合并字典.CustomControl 倾向于从基本控件继承，因此我将按 ListView、TextBox 等对它们进行分组.

I have found that the cleanest way involves creating a merged dictionary. CustomControl's tend to inherit from a base control, so I will group them by ListView, TextBox, etc.

Generic.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/YourAssembly;component/ResourceDictionaries/ListView.xaml"/>
        <ResourceDictionary Source="/YourAssembly;component/ResourceDictionaries/TabControl.xaml"/>
        <ResourceDictionary Source="/YourAssembly;component/ResourceDictionaries/TextBox.xaml"/>
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

TextBox.xaml

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

                                        <Setter Property="Visibility" Value="Collapsed" />
                                    </Style>
                                </ListView.Resources>
                                <ListView.ItemTemplate>

ValidatedTextBox.cs

namespace YourNameSpace

    public class ValidatedTextBox : TextBox
    {
        static ValidatedTextBox()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(ValidatedTextBox), new FrameworkPropertyMetadata(typeof(ValidatedTextBox)));
        }
    }
}
