Think about this for a moment. How big is the data you want to store. How long can an email address be ? How many users do you expect to have ? Are you running it on a Commodore 64 ?
Session data should be used sparingly, but storing some email addresses is not going to crash it. It's more when people fill the session with data sets, etc, and never empty it, that it can cause issues. You need to at least store something in the session to note the user that is logged in. If you store their user id, you can elect to read any other data from the DB, although this is surely going to 'cost' more to retrieve an email address every time, than if you store it in the session

No, Storing User ID, Email ID does not reduce the permanence at all. You have to rethink your design when you want to store DataTable, DataSet in Session, It can cause performance issue.

I want to make the treenodes visible or hidden based on some conditions.If the condition is true, hide the node, else visible.
I don't want to use WPF or any other libraries. Can it be possible with a few code lines. Even though I googled for sometime, it seems that it is possible only with WPF. Can anybody please provide any help on this? I have the following lines of code:
if (!htuserSecurityGroups.ContainsKey(securityGroup.Id))
{
node.SelectAction = TreeNodeSelectAction.None;
}
htuserSecurityGroups is the hashtable object and securityGroup is the collection object. This will only disable the selection. I want to make invisible the node itself? Is it possible? Please help. Thanks in advance.

Microsoft is so stupid and they can't ship all the function that we need with .NET. So we end up with writing our own functions.

Why is this forum flooded with morons at this time, every day ?
This question has nothing to do with ASP.NET, and has no real answer, apart from, buy a book and read it before you start asking questions. It's obvious you have no idea about even the rudiments of programming. On what basis could we hope to give you an answer you could understand ?

Hi,
is your database located at the the same sever as the ASP.NET application. If yes, localhost for your server is right, if not you have to change this.
Best approach for the error-issue would be to use a custom error page that will be displayed whenever an error occurs. Best would be to change the mode to "remoteOnly". Then connect to your server via RDP to get a detailed information about the error (exception type, stack trace etc.)
Regards
Sebastian

Thanks For Your support
Can You give correct syntax of CustomError what i have to write on web.config file
thanks again

The error you're seeing, is telling you that you can't see the real error, because of the web.config settings. So you need to insert the code it's telling you to insert, which will allow error messages to be shown to a remote client. You'll then get an error telling you the actual problem with your site.

Error handling can be done on Page Level, by overriding the onerror() function.
Can this be done only on master page ?
I mean, can we add an error handler on master page, rather than adding it on every single page ... ???

I am not sure that this is true. But, you can handle errors at the top level in the same place that the application start and session start events are handled.

your question makes absolutely no sense. 'every time you run the application' ? If you mean every time you do a postback, then the other answer you got is correct. If you mean what you said, what did you expect it to show ? If you want to show something else, then you need to set the selected index. Perhaps if you explain yourself better.
