我需要帮助打印我的高级数据网格。我尝试了不同的方法，但我得到的只是一张空白表。
该表在那里，但其中没有标题或数据。这是我的代码：

这是我在主代码中的打印功能：
private function doPrint():void {
var printJob:FlexPrintJob = new FlexPrintJob();
if (printJob.start()) {
// Create a FormPrintView control
// as a child of the application.
var thePrintView:SCDPrintTemplate = new SCDPrintTemplate();
thePrintView.report=report;
thePrintView.scdno=scdno.text;
// Exclude the PrintAdvancedDataGrid control from layout.
addElement(thePrintView);
// Set the print view properties.
thePrintView.width=printJob.pageWidth;
thePrintView.height=printJob.pageHeight;
//thePrintView.prodTotal = prodTotal;
// Create a single-page image.
thePrintView.showPage("single");
// If the print image's DataGrid can hold all the
// data provider's rows, add the page to the print job.
if(!thePrintView.adg.validNextPage)
{
printJob.addObject(thePrintView);
}
// Otherwise, the job requires multiple pages.
else
{
// Create the first page and add it to the print job.
thePrintView.showPage("first");
printJob.addObject(thePrintView);
thePrintView.pageNumber++;
// Loop through the following code
// until all pages are queued.
while(true)
{
// Move the next page of data to the top of
// the PrintDataGrid.
thePrintView.adg.nextPage();
// Try creating a last page.
thePrintView.showPage("last");
// If the page holds the remaining data, or if
// the last page was completely filled by the last
// grid data, queue it for printing.
// Test if there is data for another
// PrintDataGrid page.
if(!thePrintView.adg.validNextPage)
{
// This is the last page;
// queue it and exit the print loop.
printJob.addObject(thePrintView);
break;
}
else
// This is not the last page. Queue a middle page.
{
thePrintView.showPage("middle");
printJob.addObject(thePrintView);
thePrintView.pageNumber++;
}
}
}
// All pages are queued; remove the FormPrintView
// control to free memory.
removeElement(thePrintView);
}
// Send the job to the printer.
printJob.send();
}
谢谢 ：）
