【问题描述】:
我创建了一个示例自定义控件。在我构建项目后它会生成一个 dll。以下是代码。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace textbtn
{
public class CustomControl1 : Control
{
static CustomControl1()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl1), new FrameworkPropertyMetadata(typeof(CustomControl1)));
}
}
}
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:textbtn">
<Style TargetType="{x:Type local:CustomControl1}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:CustomControl1}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<TextBlock Text="This is a Test" Foreground="Aqua" Background="AntiqueWhite"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
我将此 dll 包含在另一个 WPF 应用程序中,并希望在用户单击应用程序中的按钮时显示此自定义控件。我怎么做 ?
以下是我的 WPF 应用程序中的代码。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Controls.Primitives;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
namespace TestCustomControls
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
textbtn.CustomControl1 cc = new textbtn.CustomControl1();
}
}
}
【问题讨论】:

通常最好将控件添加到 XAML,然后当您希望它显示时,只需将控件的
Visibility从Collapsed切换到Visible。您还可以使用BoolToVisibilityConverter等绑定来控制布尔属性的可见性。
