Hi,
Refer below link for what is session state and how to save and read values in session state.
http://msdn.microsoft.com/en-us/library/6ad7zeeb.aspx[^]
Brief about session state and view state:
View State are valid mainly during postbacks and information is stored in client only.
Viewstate are valid for serializable data only.
Moreover Viewstate are not secured as data is exposed to client.It get stored in browser.
Although we can configure page directive and machine key to make view state encrypted.
Session State- this is user specific data that is stored in server memory . Session state is valid for any type of objects. We can take help of session through different web pages also. But yes this is valid till that user's session.
Hope this is of help.
Cheers
Shilpa

Hi
I am really stuck in not being able to apply my Cascading Style Sheets to the nodes of my treeview. Using the tag Hover Style in the TreeView control I applied CSS, but when I run the application the hover style is not being applied, and I don't why. Also I have another problem with the same TreeVIew in that where there is a url in my SiteMap the color changes from that in the CSS, and I am unable to get those nodes, Parent or Child, to be the same as those which don't have a url.
Can anyone please help me.
Thanks

Can u give me an example how can I create a Gridview programatically.
|
|
|
|

Why, is google broken where you live ? What have you tried ? Where are you stuck ?
GridView gv = new GridView();
this.Controls.Add(gv);
Of course, you'll have issues with things like defining templates, and viewstate. Why do you need to create one programatically ? Do you need an infinite number of gridviews ?

I have a listview in which i definited a layout and item template. in the item template there is a checkbox that isn't bound to any data. it's there for me to check the code-behind which rows were selected or not. however, on postback, the checkbox's checked property always comes back false. i tried using a radio button just to test with, and the results were the same. the changed values of unbound controls inside my asp.net listview control do not get carried over.
is there a setting or some way for me to get this done ?

you know i tried something like that, using jquery though to set the hidden field value when the checkbox was clicked. i think the problem was that i had the hidden field in the listview. I'll trying placing it outside the listview templates and see if that works

Hi,
I have one menu in my web form with three items. Each item has further 25 subitems. If I click on one of this subitem it should show me a Grid view in the same page. I didn't find any property like onclick for submenu items. It NavigationUrl property. But I want to stay on the same page and just want to show Gridview in the same page by clicking on subitem I have selected

You could actually use OnclientClick to call your method. It would just have to return false to avoid a postback.

Seems like you should buy a book and read it. Hannah is my daughters name, so I will cut you a break:
1 - of course. If it's on the web, it's on the web
2 - anyone can call a webservice, but you can add security, just like you can for a website.
3 - It wouldn't matter, b/c all that matters is your output. How the output of your webservice gets into another webpage, is entirely the problem of the person writing that site.

You may have to check your Browser's security settings.
In Internet Explorer, go to Internet Options, Local Intranet, Click Custom Level.
Look in the area Active X stuff, I think you may need to Enable the option,
"Initialize and script ActiveX controls not marked as safe for scripting"
(I'm using Internet Explorer 7)
