                                                <asp:CompareValidator
                                                 ControlToValidate="txtPassword"
                                                 ControlToCompare="txtRePassword"
                                                 Display="Dynamic"
                                                 Text="<br/>Password and Re-Password does not match."
                                                 Runat="Server" />

I'm try to compare two password field from the above code.the code is working fine the only problem is that.
when the form loads it is obvious that both fields are blank.And when i type in the Password field and move to the next Re-password field that without me typing anything in Re-password field it already compares the value and gives me the Error msg (Password and Re-Password does not match.).

should it compare the values in the two textbox only after i've typed on both the text boxes or when i click the button.

thanks

you have the Validator set in REVERSE.  YOu want the validator to Validate txtRePassword against txtPassword, but you have it set backwards:

as you have it now coded:

asp:CompareValidator
                                         ControlToValidate="txtPassword"
                                         ControlToCompare="txtRePassword"
                                         Display="Dynamic"
                                         Text="<br/>Password and Re-Password does not match."
                                         Runat="Server" />

and it should be:

asp:CompareValidator
                                         ControlToValidate="txtRePassword"
                                         ControlToCompare="txtPassword"
                                         Display="Dynamic"
                                         Text="<br/>Password and Re-Password does not match."
                                         Runat="Server" />

that way the validation is not done until the txtRePassword TEXT is entered.
