组合框未在堆栈面板中正确设置宽度

Question

我正在尝试在 WPF 中设计一个表单。到目前为止：

<Window x:Class="OCLMEditor.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:local="clr-namespace:OCLMEditor"
        mc:Ignorable="d"
        Title="Christian Life and Ministry Editor" Height="517.366" Width="729.7">
    <Grid Margin="0,0,0,3">
        <StackPanel Grid.Row="0" Grid.ColumnSpan="4" VerticalAlignment="Top" >
            <Menu x:Name="menuOCLM">
                <MenuItem Header="File">
                    <MenuItem Header="Download Schedule Information"/>

问题：

有几个问题，但我将把这个问题限制为 1。组合不够宽。组合和图像应填满宽度。

Answer 1

StackPanel 旨在无限增长，它不适合您的需要。 Grid 会是不错的选择。

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="auto"/>
    </Grid.ColumnDefinitions>
    <ComboBox>
        <ComboBoxItem>
            <StackPanel Orientation="Horizontal">
                <Image Source="special_event.png"></Image>
                <Label>Date 1</Label>
            </StackPanel>
        </ComboBoxItem>
        <ComboBoxItem>
            <StackPanel Orientation="Horizontal">
                <Image Source="special_event.png"></Image>
                <Label>Date 2</Label>
            </StackPanel>
        </ComboBoxItem>
        <ComboBoxItem>
            <StackPanel Orientation="Horizontal">
                <Image Source="special_event.png"></Image>
                <Label>Date 3</Label>
            </StackPanel>
        </ComboBoxItem>
    </ComboBox>
    <Image Grid.Column="1" HorizontalAlignment="Right" Source="event_time.png"></Image>                    
</Grid>
