Re: requiredfieldvalidator cause javascript error

You're using the wrong ControlToValidate: ControlToValidate="cqidTextBox" should be "uidTextBox". [edit] either OP updated his previously posted code, or I'm clearly going blind.

Re: requiredfieldvalidator cause javascript error

thanks! but I indeed want to validate "cqidTextBox".

I thinks the problem is not relate to this. maybe relate to the setfousonerror?

Re: requiredfieldvalidator cause javascript error

Hi,

I have test the similar scenery but the SetFocusOneError dont cause an error. You can set break point and debug your code. You can also use FireBug to debug your javascript. Then you will know what has caused the error.
