Usage
Trim is useful for removing spaces that a user may have typed before or after newly entered data.
If you do not include the optional removeallspaces argument or its value is false, only the space character (U+0020) is removed from the string.
If the removeallspaces argument is set to true, all types of space characters are removed. See LeftTrim for a list of space characters.
Examples
This statement returns BABE RUTH if all the leading and trailing spaces are space characters:
Trim(" BABE RUTH ")This statement returns BABE RUTH if the leading and trailing spaces include other types of white space characters:
Trim(" BABE RUTH ", true )This example removes the leading and trailing spaces from the user-entered value in the SingleLineEdit sle_emp_fname and saves the value in emp_fname:
string emp_fname emp_fname = Trim(sle_emp_fname.Text)
