        }
        public GridSplitterControl(ColumnDefinition ColLeft)
        {
            InitializeComponent();
            Left = ColLeft;
        }
        public void Click(object sender, RoutedEventArgs e)
        {
            if (Left != null)
            {
                Left.MinWidth = 10.0;
                if ((Left.Width.Value + 10) == Left.MinWidth)
                    Left.Width = AutoSize;
                else if (Left.Width.Value != AutoSize.Value)
                    Left.Width = AutoSize;
                else Left.Width = ZeroSize;
            }
            //ClickNotify(sender, e);
        }

        public event EventHandler ClickCompleted;
        private void ClickNotify(object senderAIF, RoutedEventArgs eAIF)
        {
            if (ClickCompleted != null)
                ClickCompleted(senderAIF, eAIF);
        }
    }
  1. Click 事件可以工作，但我不知道在使用此元素的 xaml 文件中设置 Left(ColumnDefinition)。
    <Grid x:Name="LayoutRoot1"
                  Grid.Row="1"
                  Margin="5"
                  Background="White">
         <Grid.ColumnDefinitions>
              <ColumnDefinition x:Name="LvCol_10" Width="*" />
              <ColumnDefinition x:Name="LvCol_11" Width="*" />
         </Grid.ColumnDefinitions>
         <Mylayout:GridSplitterControl x:Name="GridSplitter_Left"
                                       Grid.RowSpan="7"
                                       Grid.Column="0"
                                       Width="10"
                                       VerticalAlignment="Stretch"
                                       IsEnabled="True"
                                       Left=? /> < !-- How to set "LvCol_11" in here? -->
    </Grid>`

似乎您想将 grid.row 设置为单击按钮时使用的属性。

也许你可以试试这个...

GridSplitterControl.xaml.cs

private void UI_Loaded(object sender, RoutedEventArgs e)
{
    if (sender is GridSplitter)
    {
        Grid ParentGrid = this.ParentOfType<Grid>();
        SetLocation(ParentGrid);
    }
}
public void SetLocation(Grid p_Layout)
{
    int index = Grid.GetColumn(this);
    ColumnDefinition ColLocation = p_Layout.ColumnDefinitions[index];
    ColLocation.MinWidth = 10;
    Left = ColLocation;
}

小心，确保您的元素的父级（上一级）是网格。

如果 parent 是 stackPanel、border 或 rectangle，它可能不起作用。
