We will use java script(client side) validation control with an example of Registration Form
On Registration Form we will assume some common field on the form thn we will implement the java script on that fields.Suppose we have
Textbox for Firstname = txtFirstname (Required field)
Textbox for postalcode = txtPostalcode (Numeric value)
Textbox for Email = txtEmail (Regular Expressions)


On source page we will make a function of java script





And now on cs page we will call the function (validate) on page load

Suppose the id of the button is btnRegister

On page load


btnRegister.Attributes.Add("onClick", "return validate();");

Have a nice day and enjoy client side validations.
