Reminder alart box click open page with details Windows Phon

Two ways you can do this:

1) You can pass parameters as you would in a query string in a normal URL. Eg:

Uri navigationUri = new Uri("/MainPage.xaml?date=" + _Date.ToString(), UriKind.Relative);

On the page you navigate to you can get the values like so:

string strDate = "";
NavigationContext.QueryString.TryGetValue("date", out strDate);
DateTime dtmDate = DateTime.Parse(strDate);

2) You can store your values in IsolatedStorage before navigating and retrieve them on the navigated to page. Eg:

starting page:

IsolatedStorageSettings.ApplicationSettings["date"] = _date;

target page

if (IsolatedStorageSettings.ApplicationSettings.Contains("date"))
{
DateTime dtmDate = (DateTime)IsolatedStorageSettings.ApplicationSettings["date"];
}

So, you could store your variables in an object and pass that via IsolatedStorage:

public class Reminder
{
public string _Content { get; set; }
public DateTime _Date { get; set; }
public DateTime _Time { get; set; }
public DateTime _DateTime { get; set; }
}

Reminder objReminder = new Reminder();
objReminder._Content = TextField.Text;
objReminder._Date = dpkDate.Value.Value;
objReminder._Time = tpkDate.Value.Value.TimeOfDay;
objReminder._DateTime = _Date.Date + _Time;

IsolatedStorageSettings.ApplicationSettings["objReminder"] = objReminder;

Then on your target page retrieve your object:

if (IsolatedStorageSettings.ApplicationSettings.Contains("objReminder"))
{
Reminder objReminder = (Reminder)IsolatedStorageSettings.ApplicationSettings["objReminder"];
//Get your values and do what you want
}

Hope this helps others those bogged down at same problem.

I solved with my problem with some RnD, for those who stucked at same point for them my answer help you

//Creation of the Reminder

_Content = TextField.Text;
  _Date = dpkDate.Value.Value;
  _Time = tpkDate.Value.Value.TimeOfDay;
  _Date = _Date.Date + _Time;
 
  Uri navigationUri = new Uri("/MainPage.xaml?param1=" + _Content + "&param2=" + _Date.Date + "&param3=" + _Time + "&param4=" + ((ListBoxItem)priority.SelectedItem).Content.ToString(), UriKind.RelativeOrAbsolute);
var newReminder = new Reminder(_Date.ToString())
  {
  Content = _Content,
  BeginTime = _Date,
  RecurrenceType = RecurrenceInterval.None,
  NavigationUri = navigationUri,
  // sound= new Uri("music1.wav",UriKind.Relative)
  };
  ScheduledActionService.Add(newReminder);

//Code to access the value in next page
 String note1 = NavigationContext.QueryString["param1"].ToString();
  String date1 = NavigationContext.QueryString["param2"].ToString();
  String time1 = NavigationContext.QueryString["param3"].ToString();
  String prio = NavigationContext.QueryString["param4"].ToString();

  TextField.Text = note1;
  dpkDate.Value = DateTime.Parse(date1);
  tpkDate.Value = DateTime.Parse(time1);
  if (prio == "High")
  priority.SelectedIndex = 0;
  else if (prio == "Medium")
  priority.SelectedIndex = 1;
  else
  priority.SelectedIndex = 2;
  flagr = true;
