WPF无法调整控件的大小

.net-4.0 wpf

我已经在XAML文件中搜索了单词“Width”,它只在根元素中显示一个数字作为值,设置整个控件的宽度。单词“height”在根元素和两个文本框中只有一个数值,这两个文本框与下面的复选框不在同一个网格单元中。

<Style x:Key="CheckBoxStyle1" TargetType="CheckBox">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="CheckBox">
                        <Grid ToolTipService.ToolTip="">
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CheckStates">
                                    <VisualState x:Name="Checked">
                                        <Storyboard>
                                            <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="path" d:IsOptimized="True"/>
                                        </Storyboard>
                                    </VisualState>
                                    <VisualState x:Name="Unchecked"/>
                                    <VisualState x:Name="Indeterminate"/>
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>

WPF中元素的大小不仅仅取决于宽度和高度。您还需要考虑所有对齐设置:HorizontalAlignment、VerticalAlignment,有时还有HorizontalContentAlignment和VerticalContentAlignment,以及用于排列元素的布局面板。在这里,您将复选框左对齐,这样它的宽度就永远不会超过所需的最小宽度。您还没有包括网格XAML,但是我怀疑复选框的行可能被设置为Height=“Auto”,但是如果没有看到布局的其余部分,我就不能确定。
