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.

How to make the tree node visible or hidden in treeview?

meeram3953-Aug-09 21:49

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.

Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

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.)

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.

I am astounded by the constant stream of people stupid enough to think that an entire web page reloading whenever they press a key, is a good idea.

You can handle a javascript event which will fire whenever a key is pressed. You can then write AJAX code to do this check if you want to. I think it's a dumb idea. What if what they have typed half way through exists, but they want to type some more ?

I agree with you, however I am sure you have seen at least a website full of UpdatePanels that are doing partial post backs and then the developers that don't understand the Page life circle write sh*t code that makes the whole application unmaintainable.

So if they cannot write their own JavaScript methods and being able to handle the callback of the webservices, maybe is better to do a whole postback... (very sad... but true).

having said that... that's what (and how) I would do (following Christian approach)

I would recommend you write your own javascript handler and call a webservice using the microsoft AJAX wrapper.
