Add longitude and latitude to a map manually from another page

Question

Ok, so I am very confused at this point. I am making an application in which I am sending coordinates over a page and into a string list, however, the maps "center" cannot be a string so I will need help with this.
Here is my code so far:
protected override void OnNavigatedTo(NavigationEventArgs e)
this.navigationHelper.OnNavigatedTo(e);
var list = e.Parameter as List<string>;
Data_List.ItemsSource = list;
Data_List.SelectedIndex = 0;
Artist_Text.Text = Data_List.SelectedItem.ToString();
Data_List.SelectedIndex = 1;
Venue_Text.Text = Data_List.SelectedItem.ToString();
Data_List.SelectedIndex = 2;
Region_Text.Text = Data_List.SelectedItem.ToString();
Data_List.SelectedIndex = 3;
Date_Text.Text = Data_List.SelectedItem.ToString();
Data_List.SelectedIndex = 4;
Ticket_Text.Text = Data_List.SelectedItem.ToString();
Data_List.SelectedIndex = 5;
TicketStat_Text.Text = Data_List.SelectedItem.ToString();
Data_List.SelectedIndex = 6;
VenueMap.Center = Data_List.SelectedItem.ToString();
Any help is appreciated, Thanks in advance!

Hi ZackTheNever,
Since a string can't be converted to a
Geopoint, so we can't specify a string value for the
Center property unless we use data binding.
For more information, please try to refer to:

As a workaround we can do it as the following:
For example your coordinate has been sent to the page in a string like this: "45.08,-45.08", then we can convert the string to a
Geopoint and add it to the
Center property.
string test = Data_List.SelectedItem.ToString();
var mytest = test.Split(',');
Geopoint MyGeopoint=new Geopoint(new BasicGeoposition()
Latitude =Convert.ToDouble(mytest[0]),
Longitude = Convert.ToDouble(mytest[1])
VenueMap.Center = MyGeopoint;
