We can't.
We don't know what your regular expression looks like, or what data you are entering in the textbox.
Without those, we would be guessing...

Is the new value valid in the first place?

Have you checked the contents of your textbox in the btncave_click()
method? Check the page lifetime cycle, that's often the culprit in such cases.
Page lifetime cycle[^]

Hope this helps.
