Failed to load viewstate.

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ASP.Net
 

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.

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();
        ExceptionsGridView.EditIndex = -1;
       
    }

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

  

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)
		{
			if (String.IsNullOrEmpty(Helpers.Request.Path) && Helpers.Request.ID <= 0)

Load Report Failed

  

Hi All,

I created a simple crystal report using visual studio 2008 (GAC INSTALLED VERSION 10.5.3700.0) . It is working fine locally. When I deploy it to the server when I click on the report I am seeing the empty report with  "LOAD REPORT FAILED" Text. How can I resolve this Issue?

I checked the GAC and made sure that Both are using the same version of Crystal reports . Can some one help me how to resolve this issue?

Hi Experts,I have received an error "Validation of viewstate MAC failed".I am hosting the web site on my own server, so there is nothing like a "Web Farm or cluster". Can you please advise what could be the problem with this error.I only get this error if the page is left inactive for more then 20 minutes and it throws the exception, so users have log-off and login to continue working fine.See below full error details.

Error: ASP.NET Ajax client-side framework failed to load.

  
Getting some errors after implementing the calendar control.  Error: ASP.NET Ajax client-side framework failed to load.  Here are some screenshots of the relevant info:   Here's the scenario...  I compile code locally, view the pages in a browser locally, and it all works fine.  Another developer sits down at my machine, logs in with AD account (which create a local profile for his account on my machine), and gets these errors when viewing my locally compiled code.  He then compiles the same code on my machine again just for a test, but still gets the same errors.  Can anyone come up with any good reasons for this behavior?  I put a call into MS and they suggested creating a new profile for the other developer with the errors since this appeared to be profile specific.  Tried doing that with the same results.  Help!

Getting this warning when I run my application.  I have already read the posts that repeat the 'put it in your path mantra' over and over again.  Please, do not redirect me to those posts they are useless.  I am telling you I have this DLL in my java.library.path, and I know this because I can load the DLL with java.lang.System.loadLibrary.  i even tried the directions on the MSDN sight and put the install path directly into my java.library.path.  I still get the warning.  Your driver has a bug, please fix it.
