I have written the following code on text change event of txtDate textbox.

C#

DateTime dt1 = DateTime.Parse(txtVrDate.Text.Trim()).Date;
DateTime dt2 = DateTime.Now.Date;

if ((dt2 - dt1).Days > 2)
{

    ScriptManager.RegisterStartupScript(this, typeof(string), "myalert", "alert('InValid Date');", true);
    txtDate.Text = DateTime.Parse(DateTime.Now.ToShortDateString()).ToString("dd/MM/yyyy");
    txtDate.Focus();
}

Its working on local asp.net development server but when published on IIS it does not validate textbox.I m not able to figure out whats the problem.
Please help....

Probably, it either user input or a localization problem: DateTime.Parse uses the locale of the PC it is running on - which will be your PC for development, but will be the hosting PC for production. Where the computer running IIS is located physically will determine what locale it is set for, and thus what date/time format it expects - this may not be the same as the client date/time format.

The best solution is to not use text boxes for date inputs: there is a Calendar control (or various similar) which does a better job, but which presents data in the client format, and returns a DateTime value directly to your code.
