In 4 Text boxes properties, make the cause validation
property false. And in button click event make the all text
box cause validation property true.

Answer / atish r . jaiswal

If we want the validation to be done after the click event
of the button
we can set the disply property of the validator to dynamic
vaidaton will occur so when user click on button
and not on when user left the field invalid

but as answr above
cause validation property is used to avoid the validation
to occur on some respective buttons

if we want to validate only few controls on page
then we use the valiationgroupproperty to set it with same
name to all controls in group and of the validator

Answer / guest

Write the code for validations in the button control.
