Check if Textbox has changed.

I have a Wizard control where the first WizardStep verifies registration data.  I am wondering if there is an easy way to check if the content of any of the textbox has changed.

If textbox1.text has changed or textbox2.text has changed then
run an update
end if

I have about 10 textboxes.  I know I can store the information in a Private Variable and compare the variable with the current text, but I am just wondering if there is an easier way that I have overlooked.

Thanks in advance
