TabItem 中的 ContentControl 不会适当地调整大小
ContentControl inside TabItem doesn't resize proberly
我在 TabItem 里面有一个 ContentControl。 ContentControl 显示一个 UserControl。我的问题是 ContentControl 的 Width 没有正确设置，它太大了。 Height 正确显示。
我想 SizeToContent 因为我有多个不同大小的 TabItems。
我有以下代码：
MainWindow.xaml（精简版）
<Window Height="350" Width="525" SizeToContent="WidthAndHeight">
<DockPanel>
<TabControl DockPanel.Dock="Left" TabStripPlacement="Left">
<TabItem Header="BDE Config" IsEnabled="{Binding LoggedIn}">
<Grid>
<ContentControl Content="{Binding CurrentViewModel}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
</Grid>
</TabItem>
</TabControl>
</DockPanel>
UserControl 没有 Width/Height Properties。那么，为什么 Height 是正确的，而 Width 对我的屏幕来说却很大。

这似乎与 window 上的 SizeToContent 属性 和数据网格列上的 "star-sizing" 之间的奇怪交互有关。
要么将 window 的 SizeToContent 属性 设置为 Height 并明确设置 window 的宽度，要么限制通过将它们的 MaxWidth 属性设置为某个合适的限制来设置星号大小的列。
This thread on CodePlex描述了问题。显然事情过去更糟，因为会抛出异常！来自该线程最底部的 post：
The exception has been fixed but it's still not working properly. When placed in a user control with (sic) doesn't have a fixed width, setting "*" on column width will cause the column to be extremely wide (several thousand pixel), and this happens both at design time and run time.
顺便说一句，您可以使用 StackPanel 和 DockPanel 容器而不是使用 很多 的 XAML 标记一个 Grid 代表一切。
经过更多尝试，我找到了适合我的答案。我做了以下事情：
MaxWidth="{x:Static SystemParameters.PrimaryScreenWidth}" WindowStartupLocation="CenterScreen" Left="{Binding winLeft, Mode=TwoWay}" Top="{Binding winTop, Mode=TwoWay}"
它设置 Window 的 MaxWidth 和 Screen Width，然后每当加载带有 Star-Sized Columns 的 User Control 时，它也会设置 Position 到 0,0.
我在 TabItem 里面有一个 ContentControl。 ContentControl 显示一个 UserControl。我的问题是 ContentControl 的 Width 没有正确设置，它太大了。 Height 正确显示。
我想 SizeToContent 因为我有多个不同大小的 TabItems。
我有以下代码：
MainWindow.xaml（精简版）
<Window Height="350" Width="525" SizeToContent="WidthAndHeight">
<DockPanel>
<TabControl DockPanel.Dock="Left" TabStripPlacement="Left">
<TabItem Header="BDE Config" IsEnabled="{Binding LoggedIn}">
<Grid>
<ContentControl Content="{Binding CurrentViewModel}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
</Grid>
</TabItem>
</TabControl>

UserControl 没有 Width/Height Properties。那么，为什么 Height 是正确的，而 Width 对我的屏幕来说却很大。

这似乎与 window 上的 SizeToContent 属性 和数据网格列上的 "star-sizing" 之间的奇怪交互有关。
要么将 window 的 SizeToContent 属性 设置为 Height 并明确设置 window 的宽度，要么限制通过将它们的 MaxWidth 属性设置为某个合适的限制来设置星号大小的列。
This thread on CodePlex描述了问题。显然事情过去更糟，因为会抛出异常！来自该线程最底部的 post：
The exception has been fixed but it's still not working properly. When placed in a user control with (sic) doesn't have a fixed width, setting "*" on column width will cause the column to be extremely wide (several thousand pixel), and this happens both at design time and run time.
顺便说一句，您可以使用 StackPanel 和 DockPanel 容器而不是使用 很多 的 XAML 标记一个 Grid 代表一切。
经过更多尝试，我找到了适合我的答案。我做了以下事情：
MaxWidth="{x:Static SystemParameters.PrimaryScreenWidth}" WindowStartupLocation="CenterScreen" Left="{Binding winLeft, Mode=TwoWay}" Top="{Binding winTop, Mode=TwoWay}"
它设置 Window 的 MaxWidth 和 Screen Width，然后每当加载带有 Star-Sized Columns 的 User Control 时，它也会设置 Position 到 0,0.
