You have to use a JavaScript call:

alert('You have not entered valid data');
 

The above line of code will display an alert message box with an "Ok" button.

Ya Deffinately Java Script is the best way for client side validation...
You shoud have to use Java script for all the validations...
You can put validation on Button click like,
Btn.Attributes.Add("onClick", "return function1(this.form)")
and write function in javascript according to your requirement like,
function function1()
{
alert("please enter number");
}
