How To Use Persistence To Maintain State / Relationship
Nov 29, 2010
I have to create a very simple database driven website ( for a project ) with basic features like a login system, etc. I have completed most of the basic tasks required, but there is one section that is asking me to 'Use persistence to maintain state/relationship'.
I have read a few articles and videos about persistence but I don't understand its benefits and why and how it should be used. Can anyone point me towards a site that explains how to implement state persistence in a simple way. I don't need anything advanced just a very simple way of integrating this into a very simple site to say its been done.

I have a set of dynamically-created (IE: by code) controls on my web page. Depending on which options the user decides to go (Edit/New), those controls are re-created with the appropriate information (IE: "with values" with Edit, "without values" with New).
Here's the situation:
- I create my controls in InitComplete when it comes to save the data (both on Edit/New) contained within the controls.
- I create my controls in PreLoad when it comes to load them initially (Both on Edit/New) in order to avoid the ViewState to kick in.
However, despite creating the controls after the ViewState has been applied (technically), the controls still somehow retain the pre-postback's information. IE: if I have options 2 and 4 selected and I choose "New", which should show the options without being selected, they remain selected no matter what. And this is true despite changing their values in the PreLoad state. From my understanding, creating a control in this fashion and at that point in the page lifecycle should override any values the ViewState might have had for those controls. I have also tried to disable the parent's control viewstate (Table.EnableViewState = false) again, to no avail.
I've tried using the Me.ViewState.clear() and Me.ClearChildViewSate prior to loading the initial values as well, but again all for naught. I do understand that any control created after the Init phase of the lifecycle has to play "catchup" with the current state, however I would expect that clearing the ViewState prior to creating the controls would fix this issue. It doesn't seem to.

I have a system that has several large objects that need to be built and populated each and every time, and these objects may be accessed quite often as well. As a strategy, caching would not be that good for me because there are potentially thousands of these objects which are fairly large. So I propose to serialize the objects to the file system and then deserialize it when I need those objects again. I have several classes that need this serialization functionality.
These objects change as well, so on the next access I check if there were any changes and then I grab only the changes and edit the object, and then reserialize the object.
My question is what is the best way to do this, since I have several classes ..

I have one web application. In that, I have two pages. One is view/edit page and another one is login page. The view/edit page contains one edit button and one login button.
First I execute view/edit page, at that time I dont want to show edit button. When user clicks login button, the page will be redirected to login page, where the user has to enter username and password. If user enters both correct, again the page will be redirected back to view/edit page. This time, the edit button has to be shown to make some modifications, since the user is authenticated.
I tried this thing by using session with cookieless. It works perfectly but some times it shows web page not available. I made session timeout 120 minutes and cookieless is true. In URL session ID also available.
So, whats the alternate way to maintain user log state or whats wrong in web.config file.

I am working on an existing project, setup by another coder. I'm having some trouble understanding how state is being maintained between pages. There is a Class library which has some helper objects. Mostly these objects are just used for there static methods and rarely instantiated or inherited.
This is an example class I'm testing with.
public sealed class Application
{
public static string Test;
}
Now when i run something like the following in the base class of my page, I would expect the result to be "1: 2:Test" all the time (note that "1" is empty), but strangly its only this way the first time it is run. Then every time afterwards its "1:Test 2:Test". Somehow its maintaining the state of the static variable between pages and being refreshed??
Response.Write("1:" + SharedLibrary.Application.Test);
SharedLibrary.Application.Test = "Test";
Response.Write(" 2:" + SharedLibrary.Application.Test);
I need to create more classes like this, but want to understand why this is occurring in the first place.

I'd like to maintain a session state per browser tab.
Is this easy (or even possible) to do in ASP.NET?
Example: A user hits Ctrl-T in firefox 5 times and visits the site in each tab. I'd like each tab to have its own session state on the server

I have a gridview with paging option. I want to maintain the state of the checkbox column in gridview for each page.
I used vb.net coding.
I used the following link for this purpose,
[URL]
It worked properly.
But when i check all the checkbox of page1 in gridview and click the next page, it shows that all checkbox of page2 is checked.
I know the reason for it. Because the index of the gridview row for each page will start from zero only. This causes the problem.
My requirement: I will check 2 checkbox in page1 of gridview and 1 check box in page2. I want to maintain their individual page state checkbox.

I have a requirement where i need to download mutiple files as a single zip file.There is linkbutton named HOME as well in the page. when this linkbutton is clicked it should redirect to homepage.aspx. I found a ICSharpCode.SharpZipLib.dll in net and used in my website. Here is the code
[Code]....
With the above code i got the expected result i,e. i can zip the files and save on client system. But the problem is after saving/canceling the zip file if user clicks on linkbutton in the page_load event Session[getdata] became null. there is no data in Session. what might be the problem? Actually it should redirect to homepage.aspx but its going to login.aspx because Session[getdata] is null.

I have "n" <tables></tables> on my page and each <table> has One(1) <asp:CheckBox.. Enable ='true"/> and "x" <asp:TextBox Enabled="false"..>. Each Table looks as follows
[Code]....
When I click checkbox, it calls javascript function and enables textboxes (I have added onclick attribute to checkbox). Page also has <asp:Button ...Text="Submit"/> whcih actually grabs the data from the textboxes on the page and send it to the databse. Here is the Onclick event of the <asp"button../>
[Code]....
If the exception is thrown , textBoxes are not reset but on postback textboxes appear as disabled (values are not reset)
So here is what happening on postback when exception is thrown
1) Values are not reset (that is what want)
2) Texboxes appear as Disabled (that is what I don't want on exception, REMEMBER I enable textBoxes using client side script)
How can I keep the textboxes enabled = "true"

I am using master page.
(1) to maintain the state of the treeview without storing it in session or view state or
(2) I am binding the treeview control dynamically from a xml. Even if I use session state is ther any option to use it without using SelectedNodeChanged event because when u click the treeview node , first master page will postback for this event and then the child page and then again the master page will post pack (as the child page has inherited the master page). So here in this case we are posting the master page twice and it is reducing the performance.

I know how to keep track of the checkbox in a datarow, but I got no idea on keep tracking the checkbox state in the header rows.
For example, assume my gridview have 3 pages, after I check the checkbox in the header rows in 1st page, I click on 2nd or 3rd pages, and click back to my 1st page, my checkbox status in 1st page still remains checked.
