Solution 1

Wow :)

You take a decimal value, convert it to a string, then parse it again to a decimal to round it, and convert it back to string.

You could try :

C#

lblTotalHolidayEntitled.Text = objLeave.HolidayTotalThisYear.ToString("# ##0.00");

or

C#

lblTotalHolidayEntitled.Text = Math.Round(objLeave.HolidayTotalThisYear, 2).ToString();

This is much simpler and should do what you need.

EDIT after some more informations :

If HolidayTotalThisYear is a nullable type, then you have to do :

C#

if (objLeave.HolidayTotalThisYear.HasValue) {
   lblTotalHolidayEntitled.Text = Math.Round(objLeave.HolidayTotalThisYear.Value, 2).ToString();
}

Torakami 5-Sep-13 8:05am

Solution 2

So run it through decimal.TryParse[^] instead of decimal.Parse - it checks it, does the conversion if it can and reports true or false whether the conversion succeeded or not, without throwing any exceptions.

Solution 3

The Static TryParse Method is to determine whether the representation of string is a specified valid numeric type or not. Below is the link gives in detail.
