C# - Force View-state To Be Loaded In An Earlier Stage Of The Page Life-cycle?
Mar 27, 2010I am developing a custom control that needs it's viewstate to be loaded on init. Can I antecipate the view state loading at any time?

View 2 RepliesWe are creating a composite server control. It will have few other controls. I am confused where exactly to write the code ie in which event. Is page life cycle and control life cycle follow the same event order?
View 2 Replies1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).
View 4 RepliesI am writing a web application that takes in session variables from the user and when the user comes back to the page the form elements are automatically filled with the users entery. So I tried using the page_load event to check to see if the session object was equal to null. But then when I rerun the application the form elements are filled in with the previous entery. Does this mean that if a user logs into the system and has a session withing the lifetime of a previous session that the form elements will be filled in with the previous data?

View 2 RepliesWhy class name and method name dropdown list is not similiar to vb in c# code behind.
Say for example I am getting all the events for page in vb.net, But I am not getting same as vb.net in c# while I am trying write code for page life cycle events in c#.
Apparently I am not familiar with the Life Cycle of a page in ASP.NET. This became apparent when I wanted to dispose of a Session variable after I left the page. I did what made the most sense:What I didn't know is that this would be called when I go from AND to the page. What I am wanting to do is dispose of that Session variable whenever the user leaves the page.

View 2 RepliesI'm trying to better understand the life cycle of an object in the .Net framework. My companies Intranet has some custom classes that were written by a vendor that I'm trying to make some modifications to. Specifically I want to set some variables & hashtables to null when use of the object is done. For now I have this in the dispose event.
Is there any info you can point to that would be good reading on the life cycle of an object in the .Net framework? I.e. what order do the events fire in? OnInit, Initialize, finalize Dispose, etc. I have the ASP.net page lifecycle but I'm not looking for that.

View 1 RepliesThe situation:
I have user controls with buttons that have hooked events. Controls with events need to be initialized in Page_Load or earlier.
I wish to spawn these user controls dynamically by clicking an Add button.
It is important to remember that events, such as click events, are not fired until just before Page_LoadComplete.
Broken Solution A:
[code]...
Result: Everything works great, except the button within the added user control is inert.
The conundrum is: I need controls to spawned by a button click, which means I need to put my Controls.Add(...) code in Page_LoadComplete. Inversely, I need the controls being added to have working events, which means the Controls.Add(...) code need to be in Page_Load. I have a perfect dichotomy.
I have a simple user control containing two text boxes which I am adding to placeholder on Button Click event. I am storing the number(count) of clicks in View state and running a loop using count to create all previously added user control. I am also adding IDs to each User control (appending "UC" and count). I have also checked in view source the ids are same each time they are created. I have another button which basically does an post back. I have EnableViewState enabled ="true" in all controlls all the way up to Page Level. My problem is that User Input does not persist on postback. Should this not be happening automatically for me?

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.
View 3 Replies 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 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.
