Question

我正在寻找一种方法来改变包含XAML的重用用户控件的标题。

用户控制：

<UserControl x:Class="ReusableControl"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="150" d:DesignWidth="300">
<Grid>
<GroupBox Header="Config Number">
    <Grid Name="MyConfig">
        <Grid.RowDefinitions>
            <RowDefinition Height="60" />
            <RowDefinition Height="60" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="80" />
            <ColumnDefinition Width="*" MinWidth="100"/>
        </Grid.ColumnDefinitions>

        <Label Name="Value1Label" Grid.Row="0" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Left">Value 1</Label>
            <TextBox Grid.Row="0" Grid.Column="1" 
            HorizontalContentAlignment="Left" VerticalContentAlignment="Center"
            IsEnabled="True" Margin="5,5,5,5">
                <TextBox.Text>
                    <Binding Path="Value1" StringFormat="{}{0:0.0#######}" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" ValidatesOnDataErrors="True" />
                </TextBox.Text>
        </TextBox>


        <Label Name="Value2Label" Grid.Row="1" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Left">Value 2</Label>
            <TextBox Grid.Row="1" Grid.Column="1"
            HorizontalContentAlignment="Left" VerticalContentAlignment="Center"
            IsEnabled="True" Margin="5,5,5,5">
            <TextBox.Text>
                <Binding Path="Value2" StringFormat="{}{0:0.0#######}" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" ValidatesOnDataErrors="True" />
            </TextBox.Text>
        </TextBox>

     </Grid>
</GroupBox>

</Grid>

包含窗口：

<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:StackExchangeQuestion"
Title="MainWindow" Height="500" Width="525">

<Grid>
    <StackPanel Orientation="Vertical">
        <local:ReusableControl x:Name="Config1" />
        <local:ReusableControl x:Name="Config2" />
        <local:ReusableControl x:Name="Config3" />
    </StackPanel>
</Grid>

目的是让连续的控件三次说出“Config 1”，“Config 2”，Config 3“，而不是”Config Number“。

提前感谢您的帮助！

在ReusableControl.xaml.cs中定义DependencyProperty，如下所示：

public string Header
{
    get { return (string)GetValue(HeaderProperty); }
    set { SetValue(HeaderProperty, value); }
}
public static readonly DependencyProperty HeaderProperty =
    DependencyProperty.Register("Header",
        typeof(string), typeof(ReusableControl));

现在，您可以将此Header属性用作内部Header的{{1}}属性的绑定源：

GroupBox

现在你会看到这个：

 <GroupBox Header="{Binding Header,
             RelativeSource={RelativeSource AncestorType=local:ReusableControl}}">

如何在重用的UserControl上更改WPF GroupBox标头
