State Management :: Reload Page Only Once After Being Loaded From IE Favorites Tab?
Nov 3, 2010
I have a page with several panels which are enabled or disabled depending from which page user were redirected to this particular page (based on UrlReferrer). Everything works perfectly until a user adds this page to favorites in IE8 (not sure about other browsers at this point), and then returns to that favorite in the future. It contains the previous data and not the data from the current page . When I click F5 it works again becase page is reloaded from the server and not from IE cache. How can I avoid this issue? Is there any way to force page reload only once! I tried also to put some code into "If Not IsPostBack", but it still does not work.

I have a page that loads a usercontrol dynamically. Depended on the user's actions, this control may be unloaded in Page_PreRender and a different control may be loaded instead. I am attempting to use the solution outlined by Mark DotNet Evans in this post:
http://forums.asp.net/p/1491790/3814320.aspx
This all works great, except if the user clicks the refresh button in the browser just after the change of usercontrol. Then, I get an error
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. ...
I assume the error is caused by the browser re-posting the request with the old viewstate that matched the control tree when the page was loaded, but no longer does. How can I prevent getting an error when the user reloads the page?

I have a screen with user buttons for 'Count Records' and 'Search Records'.
If a user clicks the 'Search Records' button, the matching records will be displayed on the screen.
If a user THEN clicks the 'Count Records' button, the previous records are still displayed, and a Count value is displayed.
How do i remove the previous records, if any are displayed, when a user clicks the 'Count Records' button ?

Is there a good way to keep the session after a user clicked reload/refresh? My boss wants this functionality, and I don't really/really don't want to use a query string...

I have a cascading dropdownlist. The first drop down is for Departments and is databound on PageLoad from the database. The user then selects a department and the second dropdown is populated with the appropriate sub departments via JQuery/JSON which calls an httphandler. The problem is as follows: I select a department and the subdepartments are filled.
I finish what I'm doing on that screen and everything is fine. But then if I go to a different screen and add an additional subdepartment then come back to original screen, the new sub department won't appear in the cascading dropdown. I have to close the browser and restart the session in order for any new sub departments to appear even though they are in the database. I put a breakpoint in the httphandler and noticed that it is only called once per session per each department in the first dropdown. I don't know why this is happening. I want it to call the httphander EVERY time the index of the department dropdown is changed.

I read this article first to try to solve this issue, but I am already loading the controls in the Init phase of the page, yet viewstate is not persisting. Any ideas as to why? (Of note is that this is for a custom module in DNN and I do have some AJAX update panels on the page, though this section is not within an update panel, for what it's worth.)
As an overview of what I've got:
1. LoadControl.ascx - based on reading query string parameters, determines whether to load the master or the detail .ascx.
2. Master.ascx
3. Detail.ascx
In my master control I dynamically load either a master or detail sub-control in the page_Init. The detail page has a treeview control and then uses a multi-view control to display the panel associated with the depth of the node selected on the tree. On the panel being displayed I have a cascading ddl within a detailsview control which initiates a postback to select the child ddl based on the parent ddl selection. However, when the page refreshes after the postback, both ddls have resorted to their default selection.
What is interesting however, and I just realized this as I am typing, is that the Treeview is populated when the page comes back from the postback, so that is only possible if viewstate is being persisted right? (See the page_load code and you'll see that Call PopulateRootLevel(intTreeUserID) which populates the treeview, is not called on postbacks....hmmm.
Any ideas as to why the treeview maintains viewstate but not my ddls???? But though the tree is populated, I do have to explicitly select the node again and set the panel that the detailsview control is on to visible again too....
Here is the dynamically loaded control code:

And in the Detail.ascx page load I've got:

Now here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:

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?

I am using query string to pass values from page 1(log in page) to page 2 and then page 3. I have an .ascx file also, so how can I import the user name from Page1(login.aspx) to menu.ascx file. So that when I click the menu Home the value of the variable remains at the website. I am not aware of session handling thats why I am using this method to pass the valus among the various pages in website.

I have a Web Application where I have one and only one master page and with 100's of diffrent content pages
So to speed up my Web app How can i CACHE the mater oage but not the content page??
Master page loads each time whenever content page is requested..
This thing is possible,I have seen it on many diffrent websites where the Website's Master Page Remains Intact and only the content page changes (best example would be Facebook)
How can i have the same effect in my Web Application?

In logout link's click event i have written Session.Abandon() that will destroy the Session state.I am also handling Session_End event that is fired afterward (written in Global.asax). But one more thing i want is that after Session ends, login page should be redirected (opened).
For that i wrote:
[Code]....
This is working fine on the surface, but after applying debugging i saw that there were unexpected number of calls to Session_Start and Session_End events for two times, then login page was opened.
Why Session_Start and Session_End was called two times ? If i left this process as it is working then may i get some serious error in future ?
