我有一個AdvancedDataGrid，它非常寬（需要足夠寬的大量列以便讀取），我需要打印。 PrintAdvancedDataGrid.sizeToPage屬性調整網格的高度，以便分頁僅在行之間發生。Flex PrintAdvancedDataGrid需要與sizeToPage類似的列用於列
我正在尋找類似的列。
這是一個測試案例（主程序，彈性生成器4.5）
<fx:Script>
<![CDATA[
import mx.printing.FlexPrintJob;
import mx.printing.FlexPrintJobScaleType;
protected function btnPrint_clickHandler(event:MouseEvent):void
{
doPrint();
}
private function doPrint():void {
var printJob:FlexPrintJob = new FlexPrintJob();
if (printJob.start()) {
printJob.printAsBitmap = false;
var thePrintView:PrintView = new PrintView();
thePrintView.includeInLayout = false;
addElement(thePrintView);
thePrintView.height = printJob.pageHeight;
thePrintView.myDataGrid.source = myGrid;
thePrintView.validateNow();
// This example doesn't have that many rows,
// so I'm skipping the extra code to handle "multiple pages"
printJob.addObject(thePrintView, FlexPrintJobScaleType.NONE);
removeElement(thePrintView);
}
printJob.send();
}

當你運行這個並按下打印按鈕，你會看到網頁打印了4頁。這是一件好事 - 在我的真實應用程序中，我需要廣泛的網格。我的擔心是分頁符以非常醜陋的方式分裂列。
感謝，
