wpf fixeddocument动态数据 [英] wpf fixeddocument dynamic data

问题描述

我正在创建FixedDocument并向其中动态添加页面.

I am creating FixedDocument and adding pages to it dynamically.

public partial class Window1 : Window
{
    FixedDocument fd = new FixedDocument();
    TextBlock page1Text = new TextBlock();

    public Window1()
    {
        InitializeComponent();
    }

    private void Print_Click(object sender, RoutedEventArgs e)
    {
        PrintDialog pd = new PrintDialog();


        fd.DocumentPaginator.PageSize = new Size(pd.PrintableAreaWidth, pd.PrintableAreaHeight);

        for (int i = 0; i <= 5; i++)
        {
            FixedPage page1 = new FixedPage();
            page1.Width = fd.DocumentPaginator.PageSize.Width;
            page1.Height = fd.DocumentPaginator.PageSize.Height;

            pages();
            page1.Children.Add(page1Text);
            PageContent page1Content = new PageContent();
            ((IAddChild)page1Content).AddChild(page1);
            fd.Pages.Add(page1Content);
        }

        DocumentViewer dr = new DocumentViewer();
        dr.Height = 700;
        dr.Document =fd;

        stack.Children.Add(dr);


    }

    private void pages()
    {
        page1Text.Text = "This is a test";
        page1Text.FontSize = 40;
        page1Text.Margin = new Thickness(96);

    }

}

代码仍然错误提示page1content是另一个父级的子级.

The code is still giving error that page1content is a child of another parent.

推荐答案

我做到了.解决方法如下

I did it. The solution is as follows

private void Print_Click(object sender, RoutedEventArgs e)
    {
        PrintDialog pd = new PrintDialog();


fd.DocumentPaginator.PageSize = new Size(pd.PrintableAreaWidth,fd.PrintableAreaHeight);

        for (int i = 0; i <= 5; i++)
        {
            FixedPage page1 = new FixedPage();
            page1.Width = fd.DocumentPaginator.PageSize.Width;
            page1.Height = fd.DocumentPaginator.PageSize.Height;

            UIElement page1Text = pages();
            page1.Children.Add(page1Text);
            PageContent page1Content = new PageContent();
            ((IAddChild)page1Content).AddChild(page1);
            fd.Pages.Add(page1Content);
        }

        DocumentViewer dr = new DocumentViewer();
        dr.Height = 700;
        dr.Document =fd;

        stack.Children.Add(dr);


    }

    private UIElement pages()
    {
        Canvas pcan = new Canvas();

        TextBlock page1Text = new TextBlock();
        page1Text.Text = "This is a test";
        page1Text.FontSize = 40;
        page1Text.Margin = new Thickness(96);

        pcan.Children.Add(page1Text);


        return pcan;
    }

您可以跳过画布.这是我的项目的要求，所以我正在尝试.

You can skip the canvas. It is requirment of my project so I was trying it.
