[英]Windows phone custom user control with template support
I am making a custom user control and I want the control to be reusable and a part of the control to be usable for adding new controls. 我正在制作一个自定义用户控件,我希望该控件可重用,并且该控件的一部分可用于添加新控件。 What I am trying to make is a template in the custom user control in which the user can add new content. 我要制作的是自定义用户控件中的模板,用户可以在其中添加新内容。
I am using windows phone 8 我正在使用Windows Phone 8
How can I do this? 我怎样才能做到这一点?
Add new Templated Control from "Add new item" menu. 从“添加新项”菜单中添加新的模板化控件。 You should get Generic.xaml
file in Themes
folder. 您应该在Themes
文件夹中获取Generic.xaml
文件。
In Generic.xaml
you have style for your custom control: 在Generic.xaml
您具有自定义控件的样式:
<Style TargetType="local:CustomControl1">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:CustomControl1">
Write your control xaml here
<Border x:Name="BorderNameTest"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<Button IsEnabled="{TemplateBinding IsFancyLookEnabled}"></Button>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You'll also have .cs
file for your custom control. 您还将具有用于自定义控件的.cs
文件。 To use controls (in code) from your custom control template xaml you need to use [TemplatePart]
attribute on your "control class". 要使用自定义控件模板xaml中的控件(以代码形式),您需要在“控件类”上使用[TemplatePart]
属性。 Snippet: 片段:
[TemplatePart(Name = BorderTestTemplatePartName, Type = typeof(Border))]
public sealed class CustomControl1 : Control
{
private const string BorderTestTemplatePartName = "BorderNameTest";
private Border _myBorder;
public static readonly DependencyProperty IsFancyLookEnabledProperty = DependencyProperty.Register(
"IsFancyLookEnabled", typeof (bool), typeof (CustomControl1), new PropertyMetadata(default(bool)));
public bool IsFancyLookEnabled
{
get { return (bool) GetValue(IsFancyLookEnabledProperty); }
set { SetValue(IsFancyLookEnabledProperty, value); }
}
public CustomControl1()
{
this.DefaultStyleKey = typeof(CustomControl1);
}
protected override void OnApplyTemplate()
{
_myBorder = GetTemplateChild(BorderTestTemplatePartName) as Border;
// attach events etc. (you can detach them using for example Unloaded event)
base.OnApplyTemplate();
}
}
Additionaly I have shown you how to expose properties on your control (so your control user can write <namespace:SuperControl IsFancyLookEnabled="True">
). 另外,我向您展示了如何在控件上公开属性(以便控件用户可以编写<namespace:SuperControl IsFancyLookEnabled="True">
)。 You create dependency property (as shown in code snippet) which you can use in your xaml with TemplateBinding
- or just use in code. 您创建了依赖项属性(如代码片段所示),您可以在具有TemplateBinding
的xaml中使用该属性,也可以仅在代码中使用。
