State Management :: Avoid Viewstate In Page Load Event?

Aug 30, 2010

I haveMaster Page -> ASPX page -> User ControlUser control page is contains all dynamic bind controls (e.g Repeater) depended on ASPX Page (Only one parameter say ItemNo)The problem is, if I bound user control on page load event with passing respective parameters then it's create to much view state (I checked source file and it's almost 1.5 MB)In other way if I put one textbox, and a command button and I pass required parameter on button click and load the control then page size is ok (I checked and it's < 500KB)

State Management :: Failed To Load Viewstate. The Control Tree Into Which Viewstate Is Being Loaded Must Match ?

Oct 9, 2010

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:

State Management :: Error - Failed To Load Viewstate

Jun 25, 2010

I read you can set matching keys in web.config files across a cluster.

But does it have to match across all the seperate apps on the cluster or is it in pairs?

IE... app1 on both clustered servers match or all apps on both servers have the same key?

State Management :: DataControlField Does Not Load ControlStyle From Viewstate?

Mar 12, 2011

Using ASP.NET with framework 4.0.30319, changes to the ControlStyle of a ButtonField in a GridView are not saved in Viewstate. Examining the source code suggests that this is because DataControlField.LoadViewstate does not load viewstate for the ControlStyle.

It's possible to work around this by overriding SaveViewState in the closest container and saving the state there.

State Management :: ViewState - Does The Master Page Have Its Viewstate

Apr 30, 2010

I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..

1. I use masterpage on all the pages and I need viewstate for some of the pages but..

There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?

Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?

Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?

State Management :: Dynamically Added Controls And 'Failed To Load Viewstate' Error

May 23, 2010

I am writing a search results page for an airline booking system. I have Next/Previous buttons to view flights for the next or previous days. The way i have done my results grid is that i use an HtmlTable and dynamically add rows, cells and controls into the cells. This gives ultimate flexibility given that we can add any control type we want and have it function as it does everywhere else in the system. As you should be aware - i must recreate these controls each time the page is reloaded (in the page_init event) since asp does not handle this automatically.

When they go next/previous it refreshes the flight data and re-populates the grids. If they select a flight in the return grid (by checking the RadioButton), and go next on the FIRST leg grid, the selection of the return leg stays the same after the postback
- which is great. But the problem is, if the flight they selected on the return leg is no longer available it will not create the control and i get the following error;

"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: 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. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."

Is there any way to tell asp.net that if you do not find the control anymore, simply ignore it rather than throwing the error? The nature of this design is that there potentioally WILL be a different layout after the page is posted back.

State Management :: Viewstate Error After Refreshing Page With Dynamically Loaded Controls

Jan 14, 2011

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?

State Management :: Viewstate And Dropdownlist / Initial Selection Is Lost Each Time The Page Refreshes

Jan 13, 2011

I have a simple search page with a drop down list that I would like the value to persist on refresh..basically the user will select their location from the dropdownlist and this will be used to populate a gridview. After this the page is set to refresh at a set interval and use the same location data initially selected by the user. However the initial selection is lost each time the page refreshes.

p.s system is to old for ajax!

<meta http-equiv="Refresh" content="300" />
<script runat="server">
Dim connectionString As String = ConfigurationManager.ConnectionStrings("****").ConnectionString
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
If Not IsPostBack Then
Dim conn As SqlConnection
conn = New SqlConnection(connectionString)
Dim Locationcommandtext As String
Locationcommandtext = "SELECT * FROM [Location] ORDER BY [Location]"
Dim loccomm As SqlCommand
loccomm = New SqlCommand(Locationcommandtext, conn)
Dim reader As SqlDataReader
Try
conn.Open()
reader = loccomm.ExecuteReader()
Locations.DataSource = reader
Locations.DataValueField = "LocationID"
Locations.DataTextField = "Location"
Locations.DataBind()
Catch ex As SqlException
Response.Write("SQL Error:
" & ex.ToString())
Finally
conn.Close()
End Try
Else
'"Viewstate should kick in here"
End If
End Sub
</script>

State Management :: Make ID For Each Page So VB Knows What To Load?

Mar 10, 2011

I have a script that loads diferent photo in same div on masterpage for diferent pages.

If pageID = "default1.aspx" Then
image1.ImageUrl = "~/zagreb.jpg"
ElseIf pageID = "default2.aspx" Then
image1.ImageUrl = "~/split.jpg"
End If

HTTPresponse does not help to much becouse links looks diferent every time (default.aspx?sasa , default.aspx876786 .....)

State Management :: Session Variables Destroyed With Each Page Load?

Apr 22, 2010

I'm using the beta version of Visual Studio 2010. I'm running my ASP.NET 4.0 website through the debugger. Whenever there is a page load (e.g. clicking on a link, a postback) the session is ended and a new session is created. This wipes out all the session variables and makes debugging impossible. How to get session variables to persist across page loads?

Is this problem unique to running ASP.NET in a test environment or unique to the beta 2 version of VS 2010?

State Management :: User Control And ViewState/ The Parent Page Is Not "synchronized"?

Jun 15, 2010

I make a user control with DataList to expose pagining . I choose to use ViewState to save the state of pagining (TotalItems , CurentPage etc) , but it seems the view state of the parent page is not "synchronized" with the one from user control . It's basically the same situation like the example :

I have a dummy user control :

"<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>"

and the code -behind

"public partial class WebUserControl : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)[code]...

The question is, why do I have to click twice to get the right result ...3 . I mean at the first click I still get the value 0 .

State Management :: Bug In .NET ViewState

May 20, 2010

I start with a blank ASP.NET page where I disable ViewState for the whole page with EnableViewState=False and even ViewStateMode=Disabled.keep adding various controls to the page -- Label, Table, Calendar, TextBox, DropDownList.Everything looks good, i.e. my __VIEWSTATE tag fluctuates between 24 and 28 characters.As soon as I add a single RadioButton (or CheckBox), the __VIEWSTATE shoots up to 130 characters. And it keeps growing by over 100 characters every time I add another RadioButton.
