Okay so I had this function working fine which basically takes the postcode then looks up the address from code behind and then populates some other text boxes.
But now I have added the validation checks everytime I click the button to fire the onclick event the validation is fired and the onclick function isnt called.

Is there a Validation Error, indicating that the textbox is empty? If the textbox is empty, the OnClick won't fire, as the validation is checked first before even posting back.

Nice one. Didnt think to add it to the button only the text box.
Many Thanks.
