GridSplitterControl.xaml.cs

public partial class GridSplitterControl : GridSplitter 
    { 
     GridLength AutoSize = new GridLength(1.0, GridUnitType.Auto); 
     GridLength ZeroSize = new GridLength(0.0); 
     public ColumnDefinition Left{ set; get;} 
     public GridSplitterControl() 
     { 
      InitializeComponent(); 

     } 
     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，但我不知道在使用该XAML文件来设置左（ColumnDefinition）元件。

<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>`

好像要设置grid.row财产使用该按钮的点击时。

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; 
} 

Becarefully，besure你的元素的父（一层）是网格。

如果父项是stackPanel，border或rectangle，它可能无法正常工作。
