State Management :: Maintain Page View State In Roundtrip Between Webpages?
Jun 15, 2010
I am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.
I have created a matser page with a two radio buttons, text box and a button. Whenever user sets some values to these control and clicks the button, i will navigating him from one content page to another based on the data he has entered. The problem is after the content page load, the values selected/given in the controls(radio button, text box) are getting cleared.
I have a abc.aspx page having some control like (drop downs, text boxes), i am filling a grid based on selected items in the drop downs and date selected from the ajax calender extender control attached to the from data and to date text boxes.
Inside grid there is a link which redirects to bcd.aspx, this page (bcd.aspx) is having a back button to redirect abc.aspx.
Now what i want is, abc.aspx should main its state like grid, drop downs and text boxes should be shown as it was earlier, i.e. all should have same values as it was at the time of redirecting to bcd.aspx.
Yes, there is a way to maintain the state by passing all values from query string and than get all values back and rebind all controls. But i don't want to go this way because i will have pass so many values in query string.
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 am using a treeview in my master page and every node having link to its container page.That means click on any child node of treeview its redirect to another page by taking some value.
Now every time I click on nodes of treeview, its get collaps when child page loaded...
Now regaring maintain state of treeview across my web application...
how can i maintain state in html as i am building site which has too much pages in html i can't convert them to aspx but due to some requirements i want to maintain state of variable.
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 have one method which save datatable in viewstate.i am calling this method in. page_load2. Prerenderthe page was every heavy,i did tracing of page i found due to calling of method from preprnder it doubled the viewstate sizewhat was the reseon behind this.
ViewState are used between same page Request and Response.
Session variable will stay throuwut the browsing until the Specified Expiration event.
Hidden Input control will be used whithin same page as well.
Are there any good exmples of this differences?
I wants to know the practice use here, because in hte current team, people are not prefering to use viewstate object due to some Heavy load of that object.
So i am try to use Session variable and working fine but can not see in the Viewsource of webpage.
Hidden Input control still make little weight on page compare to session..
I know the basic of view state. But I dont understand the functionality of view state at a control. For example, a texbox has a property view state. what is the purpose ? what it wiil act for true or false value.
*1* report views -- 4 options -- NOT in updatepanel *2* pagination views -- 2 options -- IS in updatepanel
The situation goes as follows: Refresh WORKS in default setting but when I select *2* radio button options and refresh the page renders the state that the (1) was entered in.
I am using the session variable to hold the Pagination Viewing option but during page states, I've noticed that when a 2nd option is selected of *2* radio buttons (doesn't matter of 1st or 2nd option was initially selected) that during debugging mode the step over corrects the issue but not the right table viewing. Upon entering Page_Init selection selection index of radio button list returns to 1st option.
I am trying to use "viewstate" inorder to 1.get the information i type in onepage and retrieve into another page.2.so i created 2 text boxes FirstName and Lastname and a submit button in first web page.3.i want to retrieve these names in the other page for which i am writing the code for button.But i dont know exactly how to use the viewstate....i tried with request.querystring and its working.So i want to use viewstate instead request.querystring.
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 to maintain session of two users on a sigle page.And the path is. UserPath:
1.User logins with his credentials((We retrive their credentials from login table) . 2.He invites some of his friends for a birthday party. 3.And send an url link to share some of the gifts with them in which gifts are provided in Share.aspx page. 4.Userlogouts.
Invites path:
1.Invite logs in with his credentials(We retrive their credentials from invites table). 2.He is directed to go to Share.aspx and list the items he require. 3.And he logs out.
Now i have problem in maintaining session for both the user and invite. How can i maintain the session so,that the user can identify a particular invite from the list of invites an his chosen items.

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)

i want to save the recent state of all controls against a button1 click event. e.g. recently selected item of a dropdownlist should persist selected when user loads page next time, if he/she had clicked button1 before leaing this page. And same for allother controls on this page.
I have a search page containing a collapsible panel with several controls including text, radio, drop list and check box. In the same page there is a gridview to display search result and links to other pages.Everytime I click on a link in the gridview, the viewstate is only maintained if I nevigate with the pagination of the gridview. However if I click on a link in the gridview and click the back button to the search, everything goes back to default, and the search results will be gone from the gridview. How may I enable the controls and the gridview to remain the same if I hit back button to it?
I'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).
i have a form on page1.aspx with several controls (textbox, dropdownlist, etc).on Page1 PageLoad event i load data from database and performe databinding.From Page1 a user can, by clicking a specific button, move to Page2.aspx to insert some details and, after saving details, he returns to page1.
if save changes are made on control on page1 before save them to db, obviously, these are lost on return from page2 (because are reloaded on pageload from db).How can i save control status between pages round trip?
Here is my scenario.In default.aspx page user selects the country, state, city from drop down list, and store them in cache for further use. but when other user open the web site from other computer it shows the same country, state, and city selected by user 1. Is there any problem related to cache? I have stored data as following.
cache["ctryID"] = ctryID;
cache["stateID"]= stateID;
cache["cityID"]= cityID;
I want to show default country, state , city at page load of default.aspx
