Set one compare validator and link it with new password controls(Textboxes),on click event of button set code which lookup on database for old given password if query match then update old password to new given password.

Storing passwords as clear text - don't you think that's a bit insecure? It is good practice to apply a 1-way salted hash[^] to passwords before storing them in a database. To check whether a user has entered the correct password, their input should be hashed and compared against the stored hash. The Membership API in ASP.NET 2.0 provides out-of-the-box support for password hashing.

So, you know his database format ? And you think it's a good idea to use default names for controls ? What if textbox1 and textbox2 accidentally were swapped ?

In order to answer this, we need to know how you store the passwords to start with. I suggest you read this[^]. I'd start by learning enough about SQL to understand how to write a database query, then you can continue to work on the codebase that you've been given, and perform the task at hand.
