Wpf 如何将按钮的宽度限制为最大跨度？

我有一个带有网格模板的ItemControls，我在其中用colspan（我正在实现一个日历）放置项目（按钮）。当“文本输入”按钮太大时，按钮宽度将超过colspan。有什么方法可以隐藏超出范围的文本

xaml：

<ItemsControl Grid.Column="1" ItemsSource="{Binding Prenotazioni}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <Grid>
                <Grid.Style>
                    <Style>

为清晰起见，我在网格上设置了列定义。背景转换器可以这样做：

<Button>
    <TextBlock Text="Text" TextTrimming="WordEllipsis"/>
</Button>

还有一个名为ClipToBound和TextWrapping的属性，请查看此属性

TextWrapping="Wrap"

您是否尝试过

MaxWidth

或

HorizontalAlignment=“Stretch”

？如果您向我们展示一些您的XAML代码，会更容易。。。
