我有一個(gè)可拖動(dòng)的 GridSplitter，并且兩列都會(huì)相應(yīng)地調(diào)整大小。我有一個(gè)可以隱藏右列的按鈕，但我希望再次按下該按鈕以再次顯示右列并且仍然可以拖動(dòng)。我曾嘗試使用 ToggleButton，但 GridSpiltter 已使用它固定且不可拖動(dòng)。我怎樣才能有一個(gè)按鈕來顯示/隱藏列并且仍然可以由用戶調(diào)整？網(wǎng)格分割器： <GridSplitter x:Name="rightSplitter" Grid.Column="1" Width="15" HorizontalAlignment="Left" VerticalAlignment="Stretch" Background="Transparent" ShowsPreview="True" />列定義：<Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="300" x:Name="rightColumn"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions>按鈕：<Button Width="50" Height="50" HorizontalAlignment="Right" x:Name="Details_Toggle" Focusable="False"> <StackPanel> <Image Source="controls/details.png" /> </StackPanel>按鈕單擊 C#： private void deatilsShowHide(object sender, RoutedEventArgs e) { rightColumn.Width = new GridLength(0); rightSplitter.Visibility = System.Windows.Visibility.Collapsed; }

由于您正在折疊正確的項(xiàng)目，因此控件不會(huì)出現(xiàn)在面板中。而不是制作 Visibility Collapsed。單擊按鈕時(shí)，我們可以將寬度設(shè)置為 10，再次單擊時(shí)，我們可以將其恢復(fù)為原始寬度。同時(shí)，我們也可以拖動(dòng)GridSplitter.
private void deatilsShowHide(object sender, RoutedEventArgs e)
{
if(rightColumn.Width == new GridLength(10))
{
rightColumn.Width = new GridLength(300);
}
else
{
rightColumn.Width = new GridLength(10);
}
}
Xaml：-
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="300" x:Name="rightColumn"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<StackPanel Grid.Column="0" Background="AliceBlue">
<Button Width="50" Height="50" HorizontalAlignment="Right" x:Name="Details_Toggle" Focusable="False" Click="Details_Toggle_Click">
<StackPanel>
</StackPanel>
</Button>
</StackPanel>
<GridSplitter x:Name="rightSplitter"
Width="15" Grid.Column="1"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Background="Transparent"
ShowsPreview="True" />
<StackPanel Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Center" >
<Button Content="test" Grid.Column="2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75"/>
</StackPanel>
</Grid>
