I cannot directly type in to the selection box.There is no option.I can only select by clicking on that particular day only,but i nees to select the days dynamically using exel data.
When you use a click activity in one of the WeekDays buttons, which selector are you getting? because the DateTime object can tell you which day of the week a date is like this:
myDateTime.DayOfWeek
so you have a part of the week day name in the title, will be fairly easy to make it dynamic, create a string variable to use as a selector and make the title value something you change before using in a click activity
