PostBack "Please Wait..." Message.

[John Walker]

Hi,
I have a datagrid with a radiobutton template column, with AutoPostBack set
to TRUE. When the user clicks on a radiobutton the application will
PostBack, and in the PostBack there will be certain logic performed, and the
dataview will be re-binded to the datagrid. There turns out to be about 2-5
seconds delay between the time the user clicks the radiobutton and when the
page is completely re-loaded. During this time the user may try clicking
into other controls unaware that the page is being refreshed, so what I'd
like to have happen is as soon as they click on the radiobutton I'll have a
popup window that states for them "to please wait..", and when the page is
finished re-loading have the popup window close. I tried doing this with
javascript and window.open and window.close but could not get it working.
Does anybody have a suggestion, or possibly sample code?

Thanks,
John

You'll have to stick with client side code, perhaps hit a javascript
group. The server side execution has no control.

You are on the right lines... you should be able to "window.open()" with
the client event and have the page send back a close call to the other
window

Eliyahu,
I found that article, but that solution was for "particularly time-consuming
operation over the Web. By 'time consuming operation' I mean all those
operations that, in a Windows Forms scenario, typically require a progress
bar."

My situation deals with only a couple to a few seconds that the user should
know not to try to make changes till the screen is refreshed. Is there a
simple way to indicate to the user that 'page is refreshing'?

John,

Sorry for the missing link, it was supposed to be there.

Even if you tell the user that 'page is refreshing', you are more interested
in disabling input controls. What about handling client-side onclick events
to disable all html inputs and show a hidden text "The page is refreshing"?
It's a hassle, but if you really want it...

John,

this article might help you.
http://www.codeproject.com/useritems...ableButton.asp

I'll post some code later/tomorrow which shows you how to pop up a window.
Basically all you have to do is to open a popup in the onsubmit event of
your form

Daniel,
I was not familiar with the "showModelessDialog" method. This will do
exactly what I need it to do!
Thanks again,
