Very easy way to validate user input its valid date

In web application validation is very basic thing when we are working on page where user needs to add input using textbox as user insert correct value Here I display case for valid date you can also do it for integer, double and all

   public static bool IsValidDate(string Date)
        {
            DateTime ValidDate;
            return DateTime.TryParse(Date, out ValidDate);
        }

I suggest to provide datetime picker to user instead of giving facility to enter some free text... Its advisable to validate in Client Side itself to prevent additional round-trip.

However, still this Datetime.TryParse() is pretty much useful...

ya that's true my point is that we can use TryParse(datatype,out bool) for check data type is valid or not in many case we have to avoid error for mis data type

I would like to add one more point here. Not only in dotnet framework, this kind of checking is also available in SQL also. In SQL we have ISNUMERIC, ISDATE.
