我有一个 Dockpanel,其中包含 Canvas 内的项目。我放置在画布内的 Dockpanel 和任何其他项目(网格等)仅占用它们所需的最小空间。如何拉伸这些项目以填充整个画布?
<Canvas x:Name="InfoCanvas" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="72,53,0,0">
<DockPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0,0,0,0" x:Name="ReferenceInfo" Canvas.Left="0" Canvas.Top="0">
<TextBox x:Name="ReferenceAuthor" GotFocus="FieldEnter" LostFocus="FieldLeave" FontSize="16" FontFamily="Segoe UI Light" Text="Author" Foreground="Gray" Background="Transparent" DockPanel.Dock="Top" VerticalAlignment="Top" HorizontalAlignment="Stretch" BorderThickness="0" Margin="0,2,0,2"/>
<TextBox x:Name="ReferenceTitle" GotFocus="FieldEnter" LostFocus="FieldLeave" FontSize="16" FontFamily="Segoe UI Light" Text="Title" Foreground="Gray" Background="Transparent" DockPanel.Dock="Top" VerticalAlignment="Top" HorizontalAlignment="Stretch" BorderThickness="0" Margin="0,2,0,2"/>
<TextBox x:Name="ReferenceDate" GotFocus="FieldEnter" LostFocus="FieldLeave" FontSize="16" FontFamily="Segoe UI Light" Text="Date" Foreground="Gray" Background="Transparent" DockPanel.Dock="Top" VerticalAlignment="Top" HorizontalAlignment="Stretch" BorderThickness="0" Margin="0,2,0,2"/>
</DockPanel>
</Canvas>
谢谢!
