Hide/Show Controls during a callback

=?Utf-8?B?U3JpZGhhcg==?=

Hi,

Is it possible to Hide/Show controls during a callback? I have a radio
button list that does the callback. When it does the callback I need to
refresh the grid to reflect the selected value in the radio button. Also I
need to hide some check boxes based on the selected value. The checkboxes and
radiobuttons are both server controls. Please let me know.

Thanks,

That won't work because there is no postback occuring where the server can
pick this up.
You need to use client script to set the display attribute of the control
(you can also use the visibility attribute; each has a different effect.)

Hi,

Thank you for the reply. I have already thought about that. Now I am having
a different problem. I am using ScriptManager and UpdatePanel controls to do
the callbacks. I have a radio button list that does the callback. The
radiobuttonlist has three options. The first option is selected by default.
So when the user gets the page for the first time it uses that option to
display the data. when I switch to another option it is doing the callback
and everything is working fine. However if I select the first option(which is
default) it is not doing the callback. I am assuming that since it didn't
update the viewstate during the callback the asp.net framework is thinking
that the selectedindex didn't change for the radiobutton list. That is why
it is not doing callback. When I searched online they sugested to call
WebForm_InitCal lback() manually. But I am not knowing where to include that
code since the ScriptManager automatically inserts the necessary javascript
code for the callbacks. Please let me know.

Thanks,

Catching authentication session timeout during remote callback

by: Sosh | last post by:

Hi, I wonder if anyone knows how an application that employs remote scripting/callbacks should deal with an authentication timeout during a callback? At the moment my application just stops working until I refresh the page and log in again. I'm not really sure what its going in - perhaps the framework is trying to redirect the callback result to the login page? Any ideas?
