C# XAML宽度设置(以百分比表示)
我有以下代码C# XAML宽度设置(以百分比表示),c#,xaml,width,C#,Xaml,Width,我有以下代码 <Grid Grid.Row="1"> <Grid.ColumnDefinitions> <ColumnDefinition Width="100*" /> <ColumnDefinition Width="100*" /> <ColumnDefinition Width="10
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100*" />
<ColumnDefinition Width="100*" />
<ColumnDefinition Width="100*" />
<ColumnDefinition Width="100*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="100*" />
<RowDefinition Height="100*" />
<RowDefinition Height="100*" />
</Grid.RowDefinitions>
<StackPanel Grid.Row="0" Grid.Column="0" Width="30*">
...
</StackPanel>
</Grid>
...
我正在尝试将Stackpanel宽度设置为单元格的30%。我已经推荐了这个职位。根据帖子,它的宽度应该是30*。但它显示了错误“30*字符串无法转换为长度”。所以我想纠正这个错误,或者我只想得到一种方法来设置宽度为单元格30%的stackpanel。谢谢。堆垛板的宽度只能是一个双人床。网格宽度可以采用*和自动(*如果未指定,则为默认值) 还要注意的是,StackPanel永远不会比内容所需的宽度更大。HorizontalAlignment=“Stretch”无效 我建议你这样做
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100*" />
<ColumnDefinition Width="100*" />
<ColumnDefinition Width="100*" />
<ColumnDefinition Width="100*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="100*" />
<RowDefinition Height="100*" />
<RowDefinition Height="100*" />
</Grid.RowDefinitions>
<Grid Grid.Row="0" Grid.Column="0" >
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<StackPanel>
</StackPanel>
</Grid>
</Grid>
stackpanel的宽度只能是一倍。网格宽度可以采用*和自动(*如果未指定,则为默认值) 还要注意的是,StackPanel永远不会比内容所需的宽度更大。HorizontalAlignment=“Stretch”无效 我建议你这样做
