问题在于，当我打印FlowDocument时，它打印的内容与Window显示的内容相同，而不是FlowDocument本身。
这是XAML：

总体而言，ListView中的项目是动态的。当列表长度超过Window的高度时，会出现问题，从而破坏报告的外观（如ellipse），并且与打印版本相同。
以下是代码隐藏：
private void Window_Loaded(object sender, RoutedEventArgs e)
{
PrintDialog printDlg = new PrintDialog();
var actualWidth = lstView.ActualWidth - 10;
lstHeader1.Width = actualWidth / 6;
lstHeader2.Width = actualWidth / 6;
lstHeader3.Width = actualWidth / 6;
lstHeader4.Width = actualWidth / 6;
lstHeader5.Width = actualWidth / 6;
lstHeader6.Width = actualWidth / 6;
PopulateListView(ChosenDate);
string businessName = "";
string businessAddress = "";
string businessTIN = "";
string businessContact = "";
string businessImage = "";
using (SqlConnection conn = new SqlConnection(constr))
{
conn.Open();
string query = "SELECT * FROM dbo.Company";
using (SqlCommand cmd = new SqlCommand(query, conn))
{
try
{
using (SqlDataReader reader = cmd.ExecuteReader())
{
if (reader.HasRows)
{
while (reader.Read())
{
businessName = reader["Name"].ToString();
businessAddress = reader["Address"].ToString();
businessTIN = reader["TIN"].ToString();
businessContact = reader["Contact"].ToString();
businessImage = reader["ImagePath"].ToString();
}
}
}
}
catch (Exception err)
{
MessageBox.Show(err.Message + err.StackTrace);
}
}
}
BitmapImage img;
if (File.Exists(AppDomain.CurrentDomain.BaseDirectory + businessImage))
{
img = new BitmapImage();
img.BeginInit();
img.CreateOptions = BitmapCreateOptions.IgnoreImageCache;
img.CacheOption = BitmapCacheOption.OnLoad;
img.UriSource = new Uri(AppDomain.CurrentDomain.BaseDirectory + businessImage);
img.EndInit();
}
else
{
img = new BitmapImage(new Uri("pack://application:,,,/Resources/default_product_img.png"));
}
imgUser.ImageSource = img;
lblCompanyName.Text = businessName;
lblCompanyAddress.Text = businessAddress;
lblCompanyTIN.Text = businessTIN;
lblCompanyNumber.Text = businessContact;
lblReportType.Text = ReportType;
lblReportDate.Text = ChosenDate.ToString("MM/dd/yyyy");
lblTotalSold.Text = TotalSold.ToString();
lblTotalCost.Text = TotalCost.ToString("F2");
lblTotalRetail.Text = TotalRetail.ToString("F2");
lblProfit.Text = TotalProfit.ToString("F2");
IDocumentPaginatorSource idpSource = flwDoc;
var result = printDlg.ShowDialog();
if (result == true)
{
printDlg.PrintDocument(idpSource.DocumentPaginator, "Document");
}
}
我认为Window中出现的用户界面仅用于视觉显示，而不是PrintDialog打印的内容，而是FlowDocument本身。如果不可能，我打算在代码隐藏中重新创建控件，以保持响应能力。所以我先问这里是否有解决方法。
