如何在WPF中使用自定义控件 [英] How to use custom Controls in WPF

问题描述

我已经在C#中创建了一个自定义控件(Button控件中的重写方法并添加了新事件).我需要在我的 wpf 应用程序中使用此控件.在 WinForms 中，我可以通过 ToolBox(右键单击)->使用它.选择项目->浏览.在WPF中，我无法导入自定义控件.有什么办法做到这一点

I have created a custom control in C# ( Overridden methods in Button control and added new events) . I need to use this control in my wpf application. In WinForms i can use this by ToolBox(right click) --> Choose Items -->Browse. where as in WPF i can not import the custom controls. Is there any way to do this

推荐答案

可能需要为特定项目进行重建，然后xaml文件应该处于活动状态.您的自定义控件应出现在工具箱中.如果没有显示.您可以执行以下操作:

might need a rebuild for the certain project then a xaml file should be active. Your custom control should appear in the toolbox. if it doesn't show. you can do the following:

在您的xaml文件中的标头标记中的某个位置，您会在其中看到许多xmlns:yyy，然后添加一个新的xmlns:例如:

in your xaml file, somewhere in the header tag, where you see many of the xmlns:yyy, add a new xmlns: for example:

<Window
    x:Class="MyProject.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:custom="clr-namespace:MyProject">

其中custom是名称空间的任何标识符，而MyProject是名称空间.不用担心，因为当您键入"xmlns:custom =(不带引号)时，intellisense将为您提供当前引用的现有名称空间的选择.因此只需从下拉列表中选择适当的名称空间，然后按Enter.

where custom is any identifier for the name space and MyProject is the namespace. Dont worry about this because when you type "xmlns:custom=" (without the quotes) intellisense will give you choice of existing namespaces currently referenced. so just choose the appropriate namespace from the drop down and press enter.

现在向下滚动到要放置自定义控件的位置，然后:

now scroll down to where you want to put your custom control and:

<custom:MyControl Content="Click Me!" Click="Button_Click" />

custom:MyControl来自xmlns: custom (上方)和控件名称 MyControl Content 是分配给"Click Me！"的Content属性.而 Click 是带有处理程序"Button_Click"的Click事件.

custom:MyControl is from the xmlns:custom (above) and the Control name, MyControl Content is the Content property assigned "Click Me!" and Click is the Click event with the handler "Button_Click".
