I have a textbox such that when the user enters the value in the textbox it should check whether the value entered is valid date or not.How to use the validation controls.

For you application, what is a "valid" date? For example in my applications a valid date is MM/DD/YYYY but some countries use the DD/MM/YYYY format so on and so on and so on.

Couple of things you can do, you can use the DateTime method TryParse() which returns a bool if the specified string can be parsed into a Valid date time. The only thing this will tell you, of course, is if the string is a valid date time.

You can also write a regular expression to check for a speicfic Date format such as MM/DD/YYYY.
