这是一个 WPF 窗口中的 XAML 代码,它描述了一个名为 "txtMessage" 的文本框控件的属性。这个文本框控件的宽度为491像素,高度为120像素,水平和垂直对齐方式分别为左对齐和顶部对齐。它允许文本折行,并且可以接受回车符,以便用户可以在文本框中输入多行文本。Margin 属性指定了该控件在窗口中的位置(距离左侧26像素,距离顶部175像素)。

<Grid x:Name="grid_1" Grid.Row="0" Margin="7, 7, 7, 50" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" > <TextBox x:Name="txtPONumbersStr" HorizontalAlignment="Center" TextWrapping="Wrap" VerticalAlignment="Top" Text="{Binding Path = PONumbersStr, Mode=TwoWay}" InputMethod.IsInputMethodEnabled ="False" PreviewTextInput="TextBox_PONumbersStr_PreviewTextInput" IsEnabled="{Binding Path=IsEnabled}" Width="{Binding ElementName=grid, Path=ActualWidth}" Height="{Binding ElementName=grid, Path=ActualHeight}" /> </Grid>, 调整代码, 使得TextBox的边框显示出来
可以在TextBox标签中添加一个Border标签,并将TextBox放在其中,代码如下:
```
<Grid x:Name="grid_1" Grid.Row="0" Margin="7, 7, 7, 50" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<Border BorderThickness="1" BorderBrush="Black">
<TextBox x:Name="txtPONumbersStr"
HorizontalAlignment="Center"
TextWrapping="Wrap"
VerticalAlignment="Top"
Text="{Binding Path = PONumbersStr, Mode=TwoWay}"
InputMethod.IsInputMethodEnabled ="False"
PreviewTextInput="TextBox_PONumbersStr_PreviewTextInput"
IsEnabled="{Binding Path=IsEnabled}"
Width="{Binding ElementName=grid, Path=ActualWidth}"
Height="{Binding ElementName=grid, Path=ActualHeight}" />
</Border>
</Grid>
```
在Border标签中设置BorderThickness和BorderBrush属性来定义边框的样式,可以根据需要进行调整。
优化 <Style TargetType="{x:Type local:CustomColorPicker}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:CustomColorPicker}"> <StackPanel> <TextBlock Text="Available Colors:"/> <ListBox ItemsSource="{TemplateBinding AvailableColors}" SelectedItem="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=SelectedColor}"/> <TextBlock Text="Hex:"/> <TextBox Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Hex, Mode=TwoWay}"/> <TextBlock Text="RGB:"/> <StackPanel Orientation="Horizontal"> <TextBox Width="40" Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=R, Mode=TwoWay}"/> <TextBox Width="40" Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=G, Mode=TwoWay}"/> <TextBox Width="40" Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=B, Mode=TwoWay}"/> </StackPanel> <Rectangle Width="50" Height="50" Margin="5" Fill="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=SelectedColor}"/> </StackPanel> </ControlTemplate> </Setter.Value> </Setter></Style> 使之有好看的排版和样式
可以尝试将该段代码进行格式化和缩进,使其更加易读和清晰。另外,可以添加注释来帮助理解模板的不同部分的作用。以下是优化后的代码:
```xml
<Style TargetType="{x:Type local:CustomColorPicker}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:CustomColorPicker}">
<StackPanel>
<!-- 显示可用颜色 -->
<TextBlock Text="Available Colors:"/>
<ListBox ItemsSource="{TemplateBinding AvailableColors}"
SelectedItem="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=SelectedColor}"/>
<!-- 显示 Hex 值 -->
<TextBlock Text="Hex:"/>
<TextBox Text="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=Hex, Mode=TwoWay}"/>
<!-- 显示 RGB 值 -->
<TextBlock Text="RGB:"/>
<StackPanel Orientation="Horizontal">
<TextBox Width="40" Text="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=R, Mode=TwoWay}"/>
<TextBox Width="40" Text="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=G, Mode=TwoWay}"/>
<TextBox Width="40" Text="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=B, Mode=TwoWay}"/>
</StackPanel>
<!-- 显示选定颜色的矩形 -->
<Rectangle Width="50" Height="50" Margin="5"
Fill="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=SelectedColor}"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
```
