Accepting Date From User

Hi,
write the functionality.....in the code behind........

apply the auto postback property to the control where u are offering date from user...
In the control related event write the datetime difference function......

Refer this link:
http://www.homeandlearn.co.uk/csharp/csharp_s14p1.html

Check the download link: for validation and all....


Modify below code to your requirement:

protected void Page_Load(object sender, EventArgs e)
{
    // Declare and get DateTime values
    DateTime StartDate = System.DateTime.Now;
    DateTime EndDate = System.DateTime.UtcNow;
 
    // Find time difference between two dates
    TimeSpan TimeDifference = StartDate - EndDate;
 
    // Write difference in hours and minutes
    Response.Write("Time difference between server time and Coordinated Universal Time (UTC) is " +
        TimeDifference.Hours.ToString() + " hours ");
    if (TimeDifference.Minutes != 0)
        Response.Write(" and " + TimeDifference.Minutes.ToString() + " minutes.");
 
}

You can write a custom validator on the validate event of the validator you can compare the textbox entered date is lesser than your server date or not.

P.S:I would always advice client side validation.
