如何在Silverlight中创建自定义控件?_Silverlight_Xaml_Custom Controls - Fatal编程技术网

如何在Silverlight中创建自定义控件?

如何在Silverlight中创建自定义控件?,silverlight,xaml,custom-controls,Silverlight,Xaml,Custom Controls,我使用Expression Blend创建了一个自定义控件: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns

我使用Expression Blend创建了一个自定义控件:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    x:Class="MyProject.EditableField"
    d:DesignWidth="286" d:DesignHeight="20">

    <Grid x:Name="LayoutRoot">
        <TextBlock HorizontalAlignment="Left" Width="95" Text="Label:" TextWrapping="Wrap" x:Name="Label" FontSize="12"/>
        <TextBox Margin="99,0,0,0" x:Name="Value" Text="Value" TextWrapping="Wrap"/>
    </Grid>
</UserControl>

它包含一个TextBlock标签和一个TextBox值。我想用它们自己的标签和值将其中的多个添加到我的XAML中,可能如下所示:

<MyProject:EditableField Margin="30,180,0,0" Height="20" HorizontalAlignment="Left" VerticalAlignment="Top" Width="286" x:Name="FaxNumber">
            <Label>
                <Text>Fax number:</Text>
            </Label>
            <Value>
                <Contents>
                    111-222-333
                </Contents>
            </Value>
        </MyProject:EditableField>

传真号码:
111-222-333

当我说也许,这显然是行不通的。添加它们的正确语法是什么?

最简单的方法是向代码中添加两个新属性,例如LabelText和ContentText。将这些连接起来,分别设置和获取TextBlock控件和TextBox控件的文本属性

然后你会使用:

<MyProject:EditableField LabelText="Fax number:" ContentText="111-222-333" ...
代码隐藏中的

public string LabelText
{
    get { return Label.Text; }
    set { Label.Text = value; }
}

public string ContentText
{
    get { return Value.Text; }
    set { Value.Text = value; }
}
