Failed to load viewstate. The control tree into which viewstate is being loaded must match the contr

Posted By:      Posted Date: October 09, 2010    Points: 0   Category :ASP.Net
 

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:

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Reflection;

namespace DJSWebCMS.Web
{
	public partial class Index : System.Web.UI.Page
	{

		private Data.Repositories.RepoClientPage repo = new DJSWebCMS.Data.Repositories.RepoClientPage(Helpers.AppSettings.DatabaseConnectionString);

		public Data.DataObjects.PageDisplay DisplayPage
		{
			get;
			set;
		}

		protected void Page_Load(object sender, EventArgs e)

Gridview RowCancellingEdit Failed to Load ViewState

  

The subject title should say it all, and I'm not sure what I've done to cause the problem.  Getting the GridView into editing doesn't pose a problem, but getting it back to read only does.

protected void ExceptionsGridView_RowEditing(object sender, GridViewEditEventArgs e)
    {
        string TXTCLIENT = ClientDropDownList.SelectedValue;
        string TXTPROV = DoctorDropDownList.SelectedValue;
        decimal TXTYEAR = Convert.ToDecimal(Calendar1.SelectedDate.Year.ToString());
        decimal TXTMMDD = Convert.ToDecimal(String.Concat(Calendar1.SelectedDate.Month.ToString().PadLeft(2, '0'), Calendar1.SelectedDate.Day.ToString().PadLeft(2, '0')));
        ExceptionsGridView.DataSource = schdExceptions(TXTCLIENT, TXTPROV, TXTYEAR, TXTMMDD);
        
        ExceptionsGridView.EditIndex = e.NewEditIndex;

        ExceptionsGridView.DataBind();

Failed to load viewstate.

  

Hi.

I had problems with my custom field generator. If I put this line of code

GridView1.ColumnsGenerator = new FieldGenerator(table, true);

in page_init event, I get no errors, but event GenerateFields never fires.

Then I found answer on this forum, that I have to move this line of code to Page_Load event, but now I ger this error, when I am selecting rows in gridview.

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. 

 


Composite Control which contains arbitrary content defined in .aspx of parent and thier ViewState

  

I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?

MyControl.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyControl.ascx.cs" Inherits="DynamicControls.Controls.MyControl" %>

<div class="box">
    <div class="Header-Left">
        <div class="Header-Right">
            My Control
        </div>
    </div>
    <div class="Content">
        <asp:PlaceHolder ID="contentPlace" runat="Server" />

viewstate in a custom control

  
I am having issues with a simple custom control that I created by subclassing the hyperlink control.

I wanted to create a control called BackLink that would automatically grab the referring url to the page when it first loads the page. and on postbacks it would continue to use the initial value

I am able to capture and set the navigateurl property when the containing page first loads just fine but if the page submits to itself, the control loses its navigateurl value.

I have the enableviewstate property set in the aspx page but it doesn't seem to want to keep its viewstate

Am I missing something? Do I have to manage my own ViewState?

here is my code
thanks
Michael

public class BackLink : System.Web.UI.WebControls.HyperLink
{

public BackLink()
{
this.Text = "<< back";
}

protected override void Render(HtmlTextWriter output)
{
if (this.Page.IsPostBack == false)
{
//save back url
Uri _backUri = this.Context.Request.UrlReferrer;

if(_backUri != null) this.NavigateUrl = _backUri.PathAndQuery;

else this.NavigateUrl = "/";
}

How to avoid viewstate in page load event??

  
Hello Everyone, Here Is my scenario,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) So is it any way I can reduce my page/state size??

Load control template file /_controltemplates/TaxonomyPicker.ascx failed

  

Hi,

Recently, we try to migrate WSS2007 solution to  SF Server 2010. And I job is to check if all the WSS 2007 solutions can work on SF Server 2010. Unfortunately, there is one weird error came out when I did a tag mapping with Microsoft.SharePoint.WebControls.PeopleEditor with my own custom people edit, it throws me this error.

Load control template file /_controltemplates/TaxonomyPicker.ascx failed: Could not load type 'Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker' from assembly 'Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.

This never occurs in WSS2007 or SF 2010, BUT it DOES occur in SF Server 2010 RTM. I reflect the Microsoft.Sharepoint.Portal.dll, and I cannot find any TaxonomyPick class at all. And I searched this solution all over the world and none of the solution(these solution inclues replace "&#44"
with ";" or change TaxonomyPicker.ascx to TaxonomyPicker.ascxbackup) is working.

Apparently, this TaxonomyPicker is obsolete in RTM. I dont know why it is still in RTM folder and it seems this causes some problems.

Please help!

Thank you.

Validation of viewstate MAC failed

  

Hello Guys we have a GPS website which is accesed all around the globe.Customers are complaining that when they keep the website running for longer periods and click the refresh button this ViewState MAC failed error appears on their page.All they had to do again is to relogin to website to keep track of their vessels .

The production webserver is not a WEBFARM or CLUSTER.

Some Important points:

 1.We have auto-update set to 15 mins for updating the map on the webpage for vessel positions by connecting to the database and weather data.

2.They can also use refresh button to update the vessel positions and weather data on the map.

so when the customer keeps the website running for longer periods at some moment it stops updating itself(I think it looses database connection) and when customer sees it and click the refresh button the ViewStateMAC validation error occurs.

I have gone through forums and have got some multiple solutions to apply but which is the correct one

1.Extending Application pool recycling periods.

2.Set EnableViewStateMac = false(But I can do this as i will have to compromise on security which is not right)

3.EnableViewStateEncryption=false...........

4.Machine key algorithm.

url rewriting causing Validation of viewstate MAC failed

  

Hi,

    Has anyone encountered while using Context.RewriteUrl in global.asax causes this error: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster ?

   Here is the scenario, let's say I have a url http://mysite.com/admin/login.aspx instead typing the whole url in address, user can type either http://mysite.com/admin/ or http://mysite.com/admin  which all end up at http://mysite.com/admin/login.aspx. When a user type http://mysite.com/admin and entered correct login info, and press login button it gets the error above. How can I resolve this? Tried setting EnableValidateRequest to false and EnableViewstateMac to false also even I do not want to use this approach and still does not work.
