public string ExecutionTime{ get; set; }

ExecutionTime value is set as dd-MM-yyyy hh:mm:ss tt
How can i change the property value to appear as yyyy-MM-dd hh:mm:ss tt and show in a textbox.

As your date is stored as string :

1. Parse the string to get the actual DateTime
2. Convert back to string with different format

You’ll need ParseExact:

// Your date
string inputDate = "20-01-2012 02:25:50 AM";

// Converts to dateTime
// Do note that the InvariantCulture is used, as I've specified
// AM as the "tt" part of the date in the above example
DateTime theDate = DateTime.ParseExact(inputDate, "dd-MM-yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);

// Now get the string to be displayed
// I've also specified the Invariant (US) culture, you might want something else
string yourString = theDate.ToString("yyyy-MM-dd hh:mm:ss tt", CultureInfo.InvariantCulture);

But you really should store a date as DateTime, not string.
