Basically, I'm trying to take information entered by the user on one page and print it out to another page via a "printer friendly" version, or report, of something. I have a MainPage.xaml that is, as the name suggests, my main page, but in a window there is the subpage AdCalculator.xaml where the user enters the information and PrintEstimate.xaml that is navigated to via a button on AdCalculator.

I would like to be able to transfer the information entered in the textboxes from AdCalculator and print it out via text blocks in PrintEstimate. So in order to do that I have the following code:

        Views.AdCalculator AdCalc = new Views.AdCalculator();
        string PrintCompanyName = AdCalc.CompanyName;
        string PrintContactName = AdCalc.txt_CustomerName.Text;
        string PrintBillingAddress1 = AdCalc.txt_BillingAddress.Text;
        string PrintBillingAddress2 = AdCalc.txt_BillingAddressLine2.Text;
        string PrintPhoneNumber = AdCalc.txt_PhoneNumber.Text;
        string PrintNumOfAds = AdCalc.txt_NumofAds.Text;
        string PrintRateOfPlay = AdCalc.Cmb_Rate.SelectedValue.ToString();
        string PrintNumOfMonths = AdCalc.txt_NumofMonths.Text;
        string PrintTotalDue = AdCalc.txt_InvoiceSummary_TotalDue.Text;

        PrintEstimate PrintEstimatePage = new PrintEstimate();
        PrintEstimatePage.txt_CompanyName.Text = PrintCompanyName;
        PrintEstimatePage.txt_CustomerName.Text = PrintContactName;
        PrintEstimatePage.txt_BillingAddress.Text = PrintBillingAddress1;
        PrintEstimatePage.txt_BillingAddressLine2.Text = PrintBillingAddress2;
        PrintEstimatePage.txt_PhoneNumber.Text = PrintPhoneNumber;
        PrintEstimatePage.txt_InvoiceSummary_NumofAds.Text = PrintNumOfAds;
        PrintEstimatePage.txt_InvoiceSummary_RateofPlay.Text = PrintRateOfPlay;
        PrintEstimatePage.txt_InvoiceSummary_NumOfMonths.Text = PrintNumOfMonths;
        PrintEstimatePage.txt_EstimateTotal.Text = PrintTotalDue;

Only problem is, when I instantiate the new AdCalculator page, it clears the values, so nothing is actually retained as far as user-input goes. Following a lead from a colleague, I believe all I need to do is change the line

        Views.AdCalculator AdCalc = new Views.AdCalculator();

to

        Views.AdCalculator AdCalc = (AdCalculator)Application.OpenForms["AdCalculator"]; 

except the "Apllication.OpenForms" doesn't register. I know there are a lot of differences in the way C# code-behind is laid out for silverlight applications, so I didn't know if there was an equivalent that anyone knew about to "Application.OpenForms" that would help solve my issue or if there was any other way to go about getting my task done.

Thank you very much!
