打印WPF DataGrid内容

Question

如何打印数据杂志的内容。我已经检查了以下帖子 我如何制作"打印预览"。WPF应用程序中的FlowDocument？它仅生成网格的可见部分而不是可滚动部分。我需要预览有多个页面，我应该使用FlowDocument，但我不确定该如何处理。任何想法，将不胜感激。

Answer 1

我曾经有一个问题。我编写了一种生成datagrid中生成 System.Windows.documents.table 的方法。我将其放在flowdocument中，并通过 XpsDocumentWriter 生成了固定的文档。然后，您将拥有数据杂志的完整分页视图，您可以在 documentViewer

使用以下方式：它可以正常工作。

public class UIPrinter
{
    #region Properties
    public Int32 VerticalOffset { get; set; }
    public Int32 HorizontalOffset { get; set; }
    public String Title { get; set; }
    public UIElement Content { get; set; }
    #endregion
    #region Initialization
    public TimelinePrinter()
    {
        HorizontalOffset = 20;
        VerticalOffset = 20;
        Title = "Print " + DateTime.Now.ToMyStringWithTime();
    }
    #endregion
    #region Methods
    public Int32 Print()
    {
        var dlg = new PrintDialog();
        if (dlg.ShowDialog() == true)
        {
            //---FIRST PAGE---//
            // Size the Grid.
            Content.Measure(new Size(Double.PositiveInfinity,
                                     Double.PositiveInfinity));
            Size sizeGrid = Content.DesiredSize;
            //check the width
            if (sizeGrid.Width > dlg.PrintableAreaWidth)
            {
                MessageBoxResult result = MessageBox.Show(Properties.Resources.s_EN_Question_PrintWidth, "Print", MessageBoxButton.YesNo, MessageBoxImage.Question);
                if (result == MessageBoxResult.No)
                    throw new PrintAborted(Properties.Resources.s_EN_Info_PrintingAborted);
            }
            // Position of the grid 
            var ptGrid = new Point(HorizontalOffset, VerticalOffset);
            // Layout of the grid
            Content.Arrange(new Rect(ptGrid, sizeGrid));
            //print
            dlg.PrintVisual(Content, Title);
            //---MULTIPLE PAGES---//
            double diff;
            int i = 1;
            while ((diff = sizeGrid.Height - (dlg.PrintableAreaHeight - VerticalOffset*i)*i) > 0)
            {
                //Position of the grid 
                var ptSecondGrid = new Point(HorizontalOffset, -sizeGrid.Height + diff + VerticalOffset);
                // Layout of the grid
                Content.Arrange(new Rect(ptSecondGrid, sizeGrid));
                //print
                int k = i + 1;
                dlg.PrintVisual(Content, Title + " (Page " + k + ")");
                i++;
            }
            return i;
        }
        throw new PrintAborted(Properties.Resources.s_EN_Info_PrintingAborted);
    }
    #endregion
}

它在多个页面上使用所选打印机打印数据杂志或任何其他控件...

用法：

        MessageBoxResult result = MessageBox.Show(Properties.Resources.s_EN_Question_Print, "Print", MessageBoxButton.YesNo, MessageBoxImage.Question);
        if (result == MessageBoxResult.Yes)
        {
            try
            {
                var border = VisualTreeHelper.GetChild(MyDataGrid, 0) as Decorator;
                if (border != null)
                {
                    var scrollViewer = border.Child as ScrollViewer;
                    if (scrollViewer != null)
                    {
                        scrollViewer.ScrollToTop();
                        scrollViewer.ScrollToLeftEnd();
                    }
                }
                Title = _initialTitle + " - " + Properties.Resources.s_EN_Info_Printing;
                var myPrinter = new UIPrinter{ Title = Title, Content = PrintGrid };
                int nbrOfPages = myPrinter.Print();
                Title = _initialTitle + " - " + Properties.Resources.s_EN_Info_PrintingDone + " (" + nbrOfPages + " Pages)";
            }
            catch (PrintAborted ex)
            {
                Title = _initialTitle + " - " + ex.Message;
            }
        }

编辑：我将datagrid放在一个简单的网格上，其中包含标头控件以在纸上放置标头。
