Datagrid getting truncated during printing

Question

Hi All,
I have a panel which contains the following items :-
1. A Header Label
2. A time slider
3. A combo box
4. A view stack which has a chart at index 0 and a data grid at index 1
5. Some buttons
For the datagrid(which is inside a VBox,whose height is 100% and verticalScrollPolicy is "on"), I have set the following attributes:-
1.variableRowHeight = true
2.rowCount = "{gridDataProvider.length}"
3.verticalScrollPolicy = "off"
4. wordWrap = true
5. dataProvider = "{gridDataProvider}"
6. updateComplete = "onUpdateComplete()"
The function onUpdateComplete is:-
private function onUpdateComplete() : void
               var  newHeight : Number;
                if ( this.gridDataProvider )   
                    this.dataGrid.headerHeight=50;
                    newHeight = dataGrid.measureHeightOfItems(0, this.gridDataProvider .length) + this.dataGrid.headerHeight ;
                    this.dataGrid.height = newHeight;
                    this.dataGrid.validateNow();
While printing, I am having a printVBox which contains all these components and its height = dataGrid.height + some buffer height for accomodating the height of other components in the panel.
I am able to print all the components, both before and after the datagrid, but the content of the datagrid is getting truncated, many rows are not printed.
Please help. Thanks in advance !!

Hi Rudhir,
You should do something like below:
private function doPrint(event:Event):void
    var printJob:FlexPrintJob = new FlexPrintJob();
    if(printJob.start() != true) return;
    try
     var originalDGHeight:int = dataGridId.height;
     //Increasing the height of the desired component to be printed without scroll.
     //Here Check  which one is giving you total height dataGridId.measuredMinHeight or dataGridId.measuredHeight
     dataGridId.height = dataGridId.measuredMinHeight;
     //dataGridId.height = dataGridId.measuredHeight;
     dataGridId.verticalScrollPolicy = "off";
     //Adding the resized Component to our FlexPrintjob and then sending the print request
     printJob.addObject(printVBox,FlexPrintJobScaleType.MATCH_WIDTH);    
     printJob.send();
     //Resizing the component back to normal size
     dataGridId.height = originalDGHeight;
     dataGridId.verticalScrollPolicy = "auto";    
    catch(error:Error)
                 trace("Error : " + error.message);
