如何使WPF数据模板填充列表框的整个宽度?

我还必须设置:

HorizontalContentAlignment="Stretch"

ListBox .

<Grid.Width>
    <Binding Path="ActualWidth" 
             RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type ScrollContentPresenter}}" />
</Grid.Width>

好的,以下是您所拥有的:

WrapPanel
第1栏:无
第2栏: ListBox

听起来像是你想要的 折叠容器 在左边, 列表框 在右边,空间占据中间剩下的东西。

最简单的方法就是使用 DockPanel ,而不是 Grid .

<DockPanel>
    <WrapPanel DockPanel.Dock="Left"></WrapPanel>
    <ListBox DockPanel.Dock="Right"></ListBox>
</DockPanel>

这将在 和 列表框 .

扩展Taeke的答案,设置 ScrollViewer.HorizontalScrollBarVisibility="Hidden" ListBox 允许子控件采用父控件的宽度,而不显示滚动条。

<ListBox Width="100" ScrollViewer.HorizontalScrollBarVisibility="Hidden">                
    <Label Content="{Binding Path=., Mode=OneWay}" HorizontalContentAlignment="Stretch" Height="30" Margin="-4,0,0,0" BorderThickness="0.5" BorderBrush="Black" FontFamily="Calibri" >
        <Label.Width>
            <Binding Path="Width" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBox}}" />
        </Label.Width>
    </Label>
</ListBox >

Grid ListBox ItemsPanel VirtualizingStackPanel . 我想你有 改变 ListBox.ItemsPanel

也许如果你去掉中间的部分 ColumnDefinition (其他为默认值 "*" ),并将 HorizontalAlignment="Left" WrapPanel HorizontalAlignment="Right" 上 列表框 电话号码。你可能得改变一下 列表框 让电话号码更准确地对齐,例如创建 DataTemplate 为了他们。

如果你想使用 Grid ,那么您需要更改您的 ColumnDefinition

    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>

如果你不需要使用 网格 ,那么你可以使用 DockPanel

    <DockPanel>
        <WrapPanel DockPanel.Dock="Left">
            <!--Some content here-->
            <TextBlock Text="{Binding Path=LastName}" TextWrapping="Wrap" FontSize="24"/>
            <TextBlock Text=", " TextWrapping="Wrap" FontSize="24"/>
            <TextBlock Text="{Binding Path=FirstName}" TextWrapping="Wrap" FontSize="24"/>
        </WrapPanel>
        <ListBox DockPanel.Dock="Right" ItemsSource="{Binding Path=PhoneNumbers}" 
 Margin="8,0" Background="Transparent" BorderBrush="Transparent" IsHitTestVisible="False"/>
        <TextBlock />
    </DockPanel>

TextBlock 最后。任何控件都没有 "DockPanel.Dock" 已定义的将填充剩余的空间。

/// <summary>
/// Value converter that adjusts the value of a double according to min and max limiting values, as well as an offset. These values are set by object configuration, handled in XAML resource definition.
/// </summary>
[ValueConversion(typeof(double), typeof(double))]
public sealed class DoubleLimiterConverter : IValueConverter
{
    /// <summary>
    /// Minimum value, if set. If not set, there is no minimum limit.
    /// </summary>
    public double? Min { get; set; }

    /// <summary>
    /// Maximum value, if set. If not set, there is no minimum limit.
    /// </summary>
    public double? Max { get; set; }

    /// <summary>
    /// Offset value to be applied after the limiting is done.
    /// </summary>
    public double Offset { get; set; }

    public static double _defaultFailureValue = 0;

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null || !(value is double))
            return _defaultFailureValue;

        double dValue = (double)value;
        double minimum = Min.HasValue ? Min.Value : double.NegativeInfinity;
        double maximum = Max.HasValue ? Max.Value : double.PositiveInfinity;
        double retVal = dValue.LimitToRange(minimum, maximum) + Offset;
        return retVal;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

<ListBox.Resources>
    <con:DoubleLimiterConverter x:Key="conDoubleLimiter" Min="450" Offset="-2"/>
</ListBox.Resources>

<Grid.Width>
    <Binding Path="ActualWidth" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type ScrollContentPresenter}}" Converter="{StaticResource conDoubleLimiter}"  />
</Grid.Width>

Taeke答案中的方法强制使用水平滚动条。这可以通过添加一个转换器来解决,通过垂直滚动条控件的宽度来减少网格的宽度。

using System;
using System.Globalization;
using System.Windows;
using System.Windows.Data;
using System.Windows.Markup;

namespace Converters
{
    public class ListBoxItemWidthConverter : MarkupExtension, IValueConverter
    {
        private static ListBoxItemWidthConverter _instance;

        #region IValueConverter Members

        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return System.Convert.ToInt32(value) - SystemParameters.VerticalScrollBarWidth;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }

        #endregion

        public override object ProvideValue(IServiceProvider serviceProvider)
        {
            return _instance ?? (_instance = new ListBoxItemWidthConverter());
        }
    }
}

将名称空间添加到XAML的根节点。

xmlns:converters="clr-namespace:Converters"

并更新栅格宽度以使用转换器。

<Grid.Width>
    <Binding Path="ActualWidth" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type ScrollContentPresenter}}" Converter="{converters:ListBoxItemWidthConverter}"/>
</Grid.Width>
