To implement the technique discussed in this article, you must either design a new browser-compatible form template or modify an existing one. The form template shown in Figure 2 is used throughout this article. It is browser-compatible and has the Main data source shown in Figure 3. The Print to PDF button control on the form template has a Clicked event handler with the code shown in Listing 1.

Figure 2: Sample InfoPath form template

Figure 3: The Main data source of the sample InfoPath form template

Listing 1: Code for the Clicked event handler of the button control

public void btnPrintToPDF_Clicked(object sender, ClickedEventArgs e)
{
  NotifyHost("PrintToPDF");
 }

Since the form template contains managed code, you will have to perform an administrator-approved deployment when you publish it to a SharePoint server running InfoPath Forms Services, and browser-enable it.
