I have been looking on Google for a while now looking for the scope of the Session object. A few sites touch base on the subject and then go straight to global variables and other random things.
What is the scope of a session object?
I have a frames page, containing 4 frames, all aspx pages. If I create a session object in one page, can I access that data on another one of those pages using the session object?

Session Object's have session level(User level) scope. It allows to access the session values in all the pages for the entire User session.

So Response.Redirects and any page changing at all with not destroy the Session contents for the life of the Session object(default 20 minutes)?

Hi,
I have a ASP.NET 1.1 application in which there are pages to add/update records. The problem is that when pages are loaded they are being stored in browser cache. Users are able to load them from their cache and perform add operations. So i require two solutions.
a) These pages should not be stored in cache without touching client browser settings, as i can currently change their settings to get new page every time but this is not acceptable.
b) If thats not possible, then how can i detect whether they have clicked the add button using original page and not cached page.
Regards

You can do as Michael said or you can use the following code in the code-behind to do the same.
Response.Cache.SetCacheability(HttpCacheability.NoCache)

When i create a new project in a location which i given, tghe solution file is saving in a default location C:\Documents and Settings\yesuprakash\My Documents\Visual Studio 2005\Projects\...
the other files are saved in the location which i given.
How can i save all files in a same folder.
Thanks and Regards

You can change the default location for saving .sln file.. Tool => Options => Projects and Solution => General => Visual studio project location..
Actually, it's not really a big problem.. You can manually "save as" the .sln in the location that you want. Another thing is that .sln is not very important for web project because you can open the webproject directly from the File-system in VS 2005.

You have to store the selection somewhere, like a cookie, or your database. Then you have to read the value and change your page to reflect the choice.

Hi all, I promise I've tried to avoid adding chatter here by doing my home work, but am kind of perplexed. I have come to the conclusion that Master Pages are not at all what I thought they were, but don't want to abandon them in the event I am wrong.
I have a large 1.1 site that I have been putting off migrating for too long, it consists of a wrapper page, default.aspx, which is primarily made up of menus (as well as home page type stuff) and an iframe object that takes up most of the real estate. That iframe displays the approximately 130 individual pages of the application, whose navigation is driven by the menus and submenus surrounding the iframe (with some cross-child page navigation as well).
It works well except for a few very unelegant methods of having my “child” pages interact with the “parent” (default.aspx). So, I am looking at Master Pages. But, as best as I can tell, this is not really their purpose or even the concept. I obviously need for a single contentholder control to be able to cycle between 130 different content pages. I’ve not seen one article written by MS or the experts that even hint at doing that, and no users writing for help that have mentioned such a problem.
Advice is appreciated, I have been playing around with making them work anyway, and already encountered some odd behavior, but I will spare you commentary on that for now.
Thank you for your time,
nowensone.

The point of a master page is to create reusable content. If you have 130 content pages, the most obvious way to do this, would be to create 130 pages that all use the same master page. The advantage is entirely that you have one place to change the parts of your UI that appear on all pages. Not sure if this is what you were hoping for - master pages are not going to work in the way you seem to be describing ( one aspx which links to a bunch of other pages ). Those other pages are instead going to use the master page.

That is (in a nutshell) what is happening now functionally, and exactly what I have been attempting to do with Master pages. Which presented me with two different problems.
One, the single content holder that the 130 different pages will all reference, and more importantly, how do I programmatically reassign the various pages/content controls to the contentholder on the master?
And two, I began by creating individual content pages (since they each logically represent a page), but their particular content did not show up on the master. They were properly referenced and created, I started out utterly simple so as not to make mistakes. That is, they did not show up until I abandoned this approach and put the multiple content areas into the application entry page default.aspx. But it does not seem right to have one gargantuan page of content for the 130 different logical pages. I have many pages that contain several thousand lines of code and html each.
I'm sure that I am doing something more fundamentally wrong than programmatically, however it's been impossible to troubleshoot since I have not ran across a single example online or via several Asp.net 2.0 books that have a contentholder on a master page being used by multiple content areas/pages.
Thank you for the quick response.

Again - that's not how master pages work. Master pages assume you have 130 different pages which all use the same master. If the 130 items were all controls, you could place them all in one page and just change which one was visible.

That's how it always works, all the pages that use a master page, fill the same content areas with different content.

Ok, the light just went on, I think I see what you are saying (and how my understanding of the concept is backwards/wrong). So my challenge then is really in the navigation controls, which sometimes are the same and sometimes not so depending on the page, but that part I can work out.
Thank you for your help.

Dear Programmers,
I need your help. I am developing a project in ASP.NET in which I am using VB.NET as Language. I want to add CheckBox in DataGrid. Even I am succeded in showing the checkbox in Datagrid but I am unable to give the user opportunity to select the checkboxes. The checkbox field directly checks or unchecks the checkbox by getting data from one of the column of my database. My database is in SQL Server 2000.
Please help me. I am also sending the scripting code below.
<%@ Page Language="VB" %>

Do you need the Checkbox to be dynamically checked or unchecked during databinding ?? Or do you mean you want the checkbox to be fire when user makes a selection in another column in the grid??
For the first, you can attach the value from the datage to the Checked event of the checkbox, so if the value bound is in bit/boolean form from the database, that sets the checked event of the checkbox to false or true.
For the second, you can set it in the such a way that when the user makes a selection in the column that determins the value of the state of the checkbox, based on selection, you either check or uncheck the checkbox in your grid

Have you read this?
Because a check box can display only a selected or an unselected state, a CheckBoxField object can be bound only to a field with a Boolean data type or a string that can be parsed by Parse.
So, if "contract" field is boolean type then the checkedbox will display a selected or unselected automatically..
If your field is a string type and the data from that column is not "1" or "0" then ~
- Try to change this column to template column
- Add one more hidden label in that column and set the datafield of this label to the database field (e.g. "contract")
- In Item_bound event, find this label and check/uncheck the checked box accordingly.
e.g. Label l = e.FindControl("myhiddenlabel");
CheckedBox c = e.FindControl("chkBoxContract");
if (l.Text == "abc"){
c.Checked = true;
}
P.S: I wrote this example just like that here without checking in Visual studio.. but you may get some ideas from this code..
Hope it helps..

is there any chance to create button to select(Deselect) all the CheckedBox Columns in my Grid with client-side script?
|
|
|
|
|
Please check-out this link below..
http://www.codeproject.com/aspnet/ChkBoxInGrid.asp[^]
but one thing... The author used a checkedbox (at the top) to select/deselect all checkedboxs in this article.. So, you should probably change this checkedbox to button...
Hope it helps..
