Why won't the WPF progressbar stretch to fit?
提问by John NoCookies
This is my original code:
这是我的原始代码：
<StackPanel Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="2" Orientation="Horizontal">
<ProgressBar Height="23" Name="searchProgressBar" Foreground="Blue" BorderBrush="#00000000" BorderThickness="1" VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
<TextBlock Text="asdf" Height="23" Name="progressTextBlock" VerticalAlignment="Top" Foreground="Red" HorizontalAlignment="Right"/>
</StackPanel>
The progressbar was very small, maybe 2 or 3 pixels wide, then there was the text block and empty space after. So I tried explicitly docking the elements to sides:
进度条非常小，可能有 2 或 3 个像素宽，然后是文本块和空白区域。所以我尝试明确地将元素停靠在两侧：
<DockPanel Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="2" >
<ProgressBar DockPanel.Dock="Left" Height="23" Name="searchProgressBar" Foreground="Blue" BorderBrush="#00000000" BorderThickness="1" VerticalAlignment="Top" />
<TextBlock DockPanel.Dock="Right" Text="asdf" Height="23" Name="progressTextBlock" VerticalAlignment="Top" Foreground="Red" HorizontalAlignment="Right"/>
</DockPanel>
No avail. I also tried modifying each solution by setting HorizontalAlignment="Stretch"on the progress bar, but there's no change. How do i stretch it to fill all the space there is after the text block has been rendered?
徒劳无功。我还尝试通过HorizontalAlignment="Stretch"在进度条上进行设置来修改每个解决方案，但没有任何变化。我如何拉伸它以填充文本块渲染后的所有空间？

Remove DockPanel.Dock="Left"from the ProgressBarand switch the order of the controls:
除去DockPanel.Dock="Left"从ProgressBar和切换控制的顺序：
<DockPanel>
<TextBlock DockPanel.Dock="Right" Height="23" VerticalAlignment="Top" HorizontalAlignment="Right"/>
<ProgressBar Height="23" VerticalAlignment="Top" />
</DockPanel>
By default, DockPanelhas its property LastChildFillset to true, which will make the ProgressBartake the available space.
默认情况下，DockPanel将其属性LastChildFill设置为true，这将ProgressBar占用可用空间。

ahh I see what you're trying to do. This is probably a better place to use a grid with 2 column definitions. The first(the left one) columndefinition with Width="*" and the second(the right one) with a width set to Width="Auto". For more info about auto vs * see http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/9a7e6591-1fae-4295-b68a-be97e8e53d06/
啊我明白你在做什么。这可能是使用具有 2 列定义的网格的更好地方。第一个（左边的）columndefinition 与 Width="*" 和第二个（右边的）的宽度设置为 Width="Auto"。有关 auto 与 * 的更多信息，请参阅http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/9a7e6591-1fae-4295-b68a-be97e8e53d06/
