I have individual calendar and time pickers. I want to combine both and convert to GMT time.

var time = timepicker.Time; //This is in 24hour format, but needs to store in AM,PM format
var date = calendar.SelectedDate;
string add_date_time = date+ " " +time;
DateTime gmt = add_date_time.ToUnviersalTime();

I get the error as

"cannot convert string to System.DateTime"

EDIT:

this is xml code for calendar and timepicker.

 <controls:Calendar  x:Name="calendar"/>
 <TimePicker x:Name="time_picker" Format = "T"/>

After converting to gmt, I want to store in DB.

Since calendar.SelectedDate is a DateTime? and timepicker.Time is a TimeSpan, the following code should work:

DateTime gmt = (calendar.SelectedDate.Value + timepicker.Time).ToUniversalTime();

You might want to check calendar.SelectedDate.HasValue is true before running this code, in case no date is selected.

You can then use this DateTime value with your database access code.
