how to validate textbox,checkbox,dropdownlist for dynmically added controls on button click

using onblur..is there any way, so that i achieve it.

Example:

1>If textbox,checkbox,dropdownlist should not empty --provide error msg
2>If checkbox should be checked and dropdownlist values should have selected value--if not error msg.
3>If checkbox should be checked ,dropdownlist should have selected index,textbox could not blank

Solution 1

Attach onblur event to every control, while they are created dynamically.
Then in that onblur JavaScript event, fetch the control and validate.
