Hello there,

I want to display the date by selecting an option from the combobox in C# winform application.

I have taken :

1. 1 = DateTimePicker
2. 1 = ComboBox // this CB contains list of Days like 10 days, 15 days, 25 days etc.

It should change automatically without clicking on the button.

For Example:

If I select 180 days then it should show me the exact date which will be after 180 days

Please help me..

What I have tried:

Sorry! I have no idea. I m new to C# winform

You get the selected date, convert the selected item to a number of days, and then add the days to the date using the AddDays method:
