我有一个带有MainWindow(MVVM)的应用程序,该应用程序由带有5个标签的TabViewer
组成。每个标签都包含ScrollViewer
,Grid
和UserControls
中的几个Grid
(MVC)。
我的MainWindow的Xml:

<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" VerticalAlignment="Top">

</StackPanel>
<TabControl Grid.Row="1">
<TabItem Width="75" Height="20" Header="Übersicht">

<help:BubbleScrollEvent />
</i:Interaction.Behaviors>
<!-- Grid I'd like to print -->

</Grid.ColumnDefinitions>
<Grid Grid.Column="1">

<RowDefinition Height="20"/>
<RowDefinition Height="180"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Orientation="Horizontal" Grid.Row="1">
<StackPanel>

</StackPanel>
</Grid>
</Grid>
</Grid>
</ScrollViewer>
</TabItem>
<TabItem Width="75" Height="20" Header="Fertigkeiten">
<ScrollViewer HorizontalScrollBarVisibility="Disabled">
<i:Interaction.Behaviors>
<help:BubbleScrollEvent />
</i:Interaction.Behaviors>
<!-- Second Grid I'd like to print -->
<Grid Name="Fertigkeiten">
<!-- [...] -->
</TabItem>
<!-- [...] -->
第一个标签页的示例:
我已经用几个红色边框标记了我的每个UserControl。
如果要简单地使用PrintDialog.PrintVisual(Übersicht, "Printing Übersicht")
,我已经实现了code from this answer并对其进行了修改,以便打印所有内容,而不只是打印青色的点线代表在DinA4页面上将被打印的区域。一个标签页,但我遇到了一些问题。
修改后的代码:
//I tried to create an array and iterate through it
System.Windows.FrameworkElement[] elements = { Übersicht as System.Windows.FrameworkElement, Fertigkeiten as System.Windows.FrameworkElement, Kampf as System.Windows.FrameworkElement,
Zauber as System.Windows.FrameworkElement, Inventar as System.Windows.FrameworkElement,};
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == true)
{
foreach (FrameworkElement e in elements)
{
//store original scale
Transform originalScale = e.LayoutTransform;
//get selected printer capabilities
System.Printing.PrintCapabilities capabilities = printDialog.PrintQueue.GetPrintCapabilities(printDialog.PrintTicket);
//get scale of the print wrt to screen of WPF visual
double scale = Math.Min(capabilities.PageImageableArea.ExtentWidth / 1281, capabilities.PageImageableArea.ExtentHeight /
1800); // I had to change ActualWidth and Height to static Values, as Grids in Tabs, which haven't been opened at least once since the start of the application had no actual size
//Transform the Visual to scale
e.LayoutTransform = new ScaleTransform(scale, scale);
//get the size of the printer page
System.Windows.Size sz = new System.Windows.Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);
//update the layout of the visual to the printer page size.
e.Measure(sz);
e.Arrange(new System.Windows.Rect(new System.Windows.Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz));
//now print the visual to printer to fit on the one page.
printDialog.PrintVisual(e, "My Print");
//apply the original transform.
e.LayoutTransform = originalScale;
}
}
现在有一些问题:
自应用程序启动以来尚未加载的所有UserControls
将为空(我的第二页有一个DataGrid。行仍然存在,但所有值都丢失了)
如果已打开选项卡,但不是当前打开的选项卡,则UserControl会保留其数据,但不会相应地调整大小(青色点线存在相同问题)
让我为您展示我第二个标签页的示例:(已扫描的DinA4页面)
第一个问题:(您可以看到带有彩色框的UserControl仍然有效,因为它已经在第一页上加载了
第二期:
仍然缺少一些代码吗?转到我的GitHub并克隆项目以自己尝试。
