You can use "AddMonths()" like selecteddate.AddMonths(-1); and assigned to textbox

use OnClientDateSelectionChanged event for ajax calendar extender. In that java script method add month -1 to selected date and set to text box.

You have to subtract a month, and then a day

dateValue = dateValue.AddMonths(-1).AddDays(-1);
