如何：创建 GridSplitter，用于自定义 DockPanel 的大小（C#、WPF）
This is my GridSplittercode, but unfortunately it is not working: I am not allowed to change the size of my grid. I can see the GridSplitter, but I cannot use it.
这是我的GridSplitter代码，但不幸的是它不起作用：我不允许更改我的grid. 我可以看到GridSplitter，但我不能使用它。
<DockPanel DockPanel.Dock="Left" Name="dockPanel_1" Width="200">
<StackPanel />
<DockPanel />
</DockPanel>
<Grid>
<GridSplitter ShowsPreview="True" Width="5" HorizontalAlignment="Right" VerticalAlignment="Stretch" />
</Grid>
<DockPanel DockPanel.Dock="Right" Name="dockPanel_2">
<StackPanel />
<DockPanel />
</DockPanel>
PS: If you know how to save the changed size, so that its to the same size when restarting the application, just add to your post.
PS：如果您知道如何保存更改的大小，以便在重新启动应用程序时其大小相同，只需添加到您的帖子中即可。
Thanks in advance.
提前致谢。

If you want to be able to resize columns/row then instead of DockPanelyou can use Gridwith GridSplitter
如果您希望能够调整列/行的大小，那么DockPanel您可以使用GridwithGridSplitter
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<DockPanel Name="dockPanel_1">
<StackPanel />
<DockPanel />
</DockPanel>
<GridSplitter Width="5" HorizontalAlignment="Right" VerticalAlignment="Stretch" ResizeBehavior="CurrentAndNext"/>
<DockPanel Grid.Column="1" Name="dockPanel_2">
<StackPanel />
<DockPanel />
</DockPanel>
</Grid>
