PrintDataGrid printing only half the page

[paulcortez]

Hello,

I have a problem printing my report with PrintDataGrid. I just copied and paste the sample code form this site but it seems to have a problem. The print out in the paper is only half and jumps to another page. 1 to 6 row is on the first page and the rest is on the next page which supposed to be on a single page. I'm asking for your help finding ways to make it print correctly.

here i have the code:

FormSalesTransaction.mxml

<fx:Script>
          <![CDATA[
               import mx.core.*
                    
                    // Declare and initialize the variables used in the component.
                    // The application sets the actual prodTotal value.
               [Bindable]
               public var pageNumber:Number = 1;
               [Bindable]
               public var prodTotal:Number = 0;
               
               // Control the page contents by selectively hiding the header and
               // footer based on the page type.
               public function showPage(pageType:String):void 
               {
                    if(pageType == "first" || pageType == "middle") 
                    {
                         // Hide the footer.
                         footer.includeInLayout=false;
                         footer.visible = false;
                    }
                    if(pageType == "middle" || pageType == "last") 
                    {
                         // The header won't be used again; hide it.
                         header.includeInLayout=false;
                         header.visible = false;
                    }
                    if(pageType == "last") 
                    {
                         // Show the footer.
                         footer.includeInLayout=true;
                         footer.visible = true;
                    }
                    //Update the DataGrid layout to reflect the results.
                    validateNow();
               }
          ]]>

     </mx:VBox>
     <MyComp:FormPrintHeader id="header"/>

               <mx:DataGridColumn headerText="Model" dataField="ModelNo" width="70"/>

               <mx:DataGridColumn headerText="Lay Pay" dataField="LayawayPayment" width="80"/>
          </mx:columns>
     </mx:PrintDataGrid>

and the way i call it from Report.mxml:

var printJob:FlexPrintJob = new FlexPrintJob();
                    
if (printJob.start()) {
        var thePrintView:FormSalesTransaction = new FormSalesTransaction();
     addElement(thePrintView);
                         
     thePrintView.width=printJob.pageWidth;
     thePrintView.height=printJob.pageHeight;
                                             
     thePrintView.prodTotal = prodTotal;
                         
     thePrintView.myDataGrid.dataProvider = salesTransaction;
                         
     thePrintView.validateNow();
                         
     if(!thePrintView.myDataGrid.validNextPage)
     {
          thePrintView.showPage("single");
          printJob.addObject(thePrintView, FlexPrintJobScaleType.MATCH_WIDTH);
     }
     else
     {
          thePrintView.showPage("first");
          printJob.addObject(thePrintView, FlexPrintJobScaleType.MATCH_WIDTH);
          thePrintView.pageNumber++;
                              
          while(true)
          {
               thePrintView.myDataGrid.nextPage();
                                   
               thePrintView.showPage("last");  
                                   
               if(!thePrintView.myDataGrid.validNextPage) 
               {
                    printJob.addObject(thePrintView, FlexPrintJobScaleType.MATCH_WIDTH);
                    break;
               }
               else
               {
                    thePrintView.showPage("middle");
                    printJob.addObject(thePrintView, FlexPrintJobScaleType.MATCH_WIDTH);
                    thePrintView.pageNumber++;
               }
          }
     }
     removeElement(thePrintView);
}          
printJob.printAsBitmap = false;                    
printJob.send();

Here is the output when I print the report:

I hope you could have some time to help me.

Thankz a lot.

Can you check and see if the variableRowHeight attribute makes any difference if set to false?

It looks like a container issue.

[paulcortez]

Great! It solves the problem. Thank you so much CrazyMerlin. I set variableRowHeight to true because of that print problem on the last row of every page.

Thankz again man.
