if you write like
<input type="button" value="mybutton" onclick="javascript:func();return false;" />
here if onclick returns false, the event bubbling will not occur and thus the form will not be posted back.

Why do we need to return false if it is client side button ?

What kind of button ? ASP Button or Input Button ? Are you calling any javascript on click of that button ?

Show us the code of DoAction() Method.I guess you need to return false; based on condition to avoid the postback,

hi all;
Is it possible to load native xml which has a special character '&'.?
|
|
|
|
|
How do you mean ? Load it in the browser ? If it has a & and it means &, it's not XML, XML will be encoded properly.

You could try replacing & with & in your string before reading it.

I have a web application.
I want to be able to detect the user when they logoff. When they close the browser without logging off through our application. We are currently using a record in the database to track that user. We are able to handle this process if they logout normally through the app. Please help me on this issue.
Thanks in advance

Some times we need to detect the Browser Close to perform some operation before quiting from application. Here is a simple way.
function CheckBrowser()
{
if(window.event.clientX < 0 && window.event.clientY <0)
{
window.open("Operation.aspx",
"Operation",'left=12000,top=1200,width=10,height=1');
}
}
One Operation.aspx you can perform the database cleaning operation.

Thanks Abhijit,
actually i have tried this before, but it will not work if pop up are blocked at client side... do you have any idea on this....
|

You can make an AJAX call in that event, too. Of course, nothing you do is guarenteed to work, but an AJAX call will be more likely to work than a popup.

Hi Abhijit,
As we have discussed regarding "window.open". As we know, the only issue with this is if the pop up is blocked at client side then this will not
work. this can be also handle, my concern is, can we stop window.open on page refresh event... because if i refresh then also this code is
executing... Please reply.....
Thanks

Yes It will not work if popup is blocked. Please try to implement as CG suggested insted of opening a popup.

we can detect the user if he log off from your application or when close the browser. If the net disconnect..then the real issue arise, in such condition it is difficult to detect the user
