Hi, I'm using FlowChart.NET 4.3.1

What I want to do is add an object to the flowchart whenever the user wants to print it, some sort of header table. What I'm doing now is catching the PrintPage event of the PrintDocument and adding the object to the chart before printing. Which works fine.

However, when I scale to page, I would like it to be scaled without taking into account the added object. I was going to do this by inheriting the "PrintPreviewForm" class, but that class is internal so I can't modify the behavior. Second thing I tried was inheriting first the FlowChart and then PrintOptions, to customize the ScaleToPage() method. But PrintOptions is sealed.

Is there a good reason why it is sealed? (I might change that, having the source code and a license, but I'd prefer not to.)

Does anybody know an alternative way of achieving my goal that I haven't thought of?

Thanks!

Thanks for the reply. Using the Graphics object would have made it difficult to move the chart down, as parts might have been cut of I think (no new page is made when you draw further than the first page...).

Nonetheless, I've found a different solution that is most convenient. In the PrintPage event, I check to see if the Scale value of my chart is 100. If it is not, then I'm asuming "Scale To Page" was pressed (as I don't allow users to zoom, this can only happen with the scale to page).

If it is not scaled, I just do what I did before. I remove the header (if present), I pull down the chart (select all and move down) and draw a header on top.

If it is scaled to page however, I remove my header (which is always drawn by default on the print preview), recall fc.PrintOptions.ScaleToPage() and then I redraw the header with the correct sizes again.

This makes the header the same size on the paper in any case.

It doesn't work as well when you change to landscape from portrait... but for now I'm happy with this workable result.

(Incidently, is there any documentation on here about compiling and using the FlowChart.NET source code? I was failing pretty bad at that ...)
