Hi Jignesh if you are using windows forms. have a look at this url. http://msdn.microsoft.com/en-us/library/ms229603.aspx Windows Forms Programming User Input Validation in Windows Forms When users enter data into your application you may want to verify that the data is valid before your application uses it. You may require that certain text fields not be zero-length that a field be formatted as a telephone number or other type of well-formed data or that a string not contain any unsafe characters that could be used to compromise the security of a database. Windows Forms provides several ways for you to validate input in your application. Thank you
