  • Landscaping a user control

    • Dear Sir,
      This is a great article.
      My problem is similar to what you described for landscape printing, but at the same time it is little bit different.
      My user control that is being used as page visual is defined with various data templates (uses a data grid).
      Printing in landscape from the print control dialog box works great but I want to print my user control in landscape mode by default. I tried several options none seem to give me the same effect as that of the print control dialog (from MS).
      In the example you described you used an Image so we would know its pixel widths and heights. But in my case it is a user control whose width and height are determined based on data at run time. So I am not sure how print dialog is able to figure out how to correctly landscape it, but I am not?
      Could you shed some light?
