.net Ajax asyncronus postback probs

M

Mukesh

HI
all

I have created a user ctrl for user info.
On which i have used some asp ctrls, .net Ajax (Atlas) Ctrls and
validation as described below

Name TxtBox1(RequiedFieldValidator, RagexValidetor)
Email TxtBox2(RequiedFieldValidator, RagexValidetor)
Mobile Txtbox3(RagexValidetor)
Date of Birth txtBox4+CalenderExtender(Ajax Ctrl tool kit)(RagexValidetor)
Country DropDownMenu1 (autoppostback)
State DropDownMenu2 (autoppostback)
City DropDownMenu3 (autoppostback)
Address TextBox5
Pincode TextBox6

When i select country the state list is populated and slecting sate the
city list is populated and city selection prefills the pincode.
The whole User Ctrl is places in User.aspx in a UpdatePanel. so all the
post backs are asyncronus callbacks.


Problem is that when i selects the country all the Validation goes
inactive using firefox. an in ie it given null exception alert please help
me


Thx in advance

Hi Mukesh,

Would you please post a complete code listing of your control so that I can
reproduce the issue on my side? Thanks.

By the way, please note CalendarExtender is part of AJAX Control Toolkit
that is shared source supported by community.
