Hai,

Here am using c# windows application , in this project I want to calculate the end date.

Here am using textbox for enter the total number of months and one datetimepicker for start date after I fill these details the second datetime picker will show the exact date based on the textbox value and datetimepicker1.

How can I do this in my project.

For an example:

Textbox1: 11 ( manual entry)

DatetimePicker1: 16-11-2015(manual entry)

DatetimePicker2:16-10-2016 (system generate)

Please anybody help this question, it is urgent now .

Hi Pavithra

Try this code in dateTimePicker_Changed event

int val =Convert.ToInt16(textBox1.Text);

string theDate =this.dateTimePicker1.Value.ToString("yyyyMMdd");

DateTime dt = DateTime.ParseExact(theDate, "yyyyMMdd", CultureInfo.InvariantCulture);
dt = dt.AddMonths(val);
textBox2.Text = dt.ToString();
