How to Validate 3 textBox controls using a single RequiredValidator?

[crazy_mads]

I have 3 TextBoxes which hold Addresses. Only if all the three textBoxes are blank i need to display a Message saying, Address cant be left blank. Even if any one of the textBox is filled i should not display the message. I have to do this in the client side and then on the click of a button i need to validate the address(i call a function in the code behind page in C# to check the format) Please help me. How do i go abt? :( Mads

I not so sure about how to accomplish this task with required field validator but you can use javascript code for this purpose. Custom validator can serve the purpose.
