I have a web page which is using PasswordRecovery control.Its working fine but I have a scenario in which I have to disable Viewstate for the whole application.Now after disabling viewstate when I visit the webpage I have noticed that PasswordRecovery controls is not working (Every times when I submit the default button to go to step 2, the postback occur but not moving to step 2).
View 3 RepliesI thought disabling ViewState for a server control would cause this control not to keep its state after a postback. I thought the same would happen if I disable ViewState for the whole page.
However, I tried to create an example to show this to a colleague and was puzzled when a textbox on a page would keep is state (in this case its Text property) after one or more postbacks, even when ViewState is disabled everywhere (both at Page level and Server Control level). Please see the code below:
[Code]....
I can keep pressing the Post back! button and every value typed on the textbox is still there after the postback(s). I'm using VS 2008.
After this example I now assume I don't understand ViewState as I thought I was.

I'm using the asp:ChangePassword control. I would like to disable the ability for the user to enter a new username but the default shows the current user's UserName and allows editing. Ideally, I would be able to find the child control in the ChangePassword control that is the UserName textbox and set Enable=false.
View 2 RepliesIs it possible to make the viewstate false of whole page including all controls at a time.I mean I don't want to set enableviewstate="false" for all controls..In the page directive of the aspx page I have made enableviewstate="false" but still viewstate of all the controls of the is enabled.. And what the EnableViewState="False"actually works within Page directive.
View 3 RepliesI want to disable StepNextButton after it's clicked (to avoid multiclicking).
The problem with OnClientClick="this.disabled=true;" that it cancels the postback and doesn't continue to a next wizard step.
I have a page that has two drop down lists on it and a button. All controls sit in an update panel. The first drop down list (ddl1) contains a lot of values which caused a huge viewstate so I disabled viewstate on it. In the page oninit event I populate the drop down list every time the page is posted back. This all seems to work fine, it shows all the values and I can access the selected value in my event handler.
ddl1 has the autopostback attribute set to true so when its value changes the second drop down list (ddl2) is populated with some values that depend on the selection in ddl1. This also works fine, the values in ddl2 change when I select a value in ddl1.
ddl2 does not have viewstate disabled. The button that sits under my two drop down lists is disabled by default and becomes enabled when the value of ddl2 is changed to anything except string.empty. This is where I run into problems. ddl2 does an autopostback too but it seems to lose the selected index/value. When I'm in my code to check whether to enable or disable the button the selected index is always 0 and the selected value is string.Empty.
If I enable viewstate on ddl1 this all works fine. Could anyone point me to what I'm doing wrong?
Here is the code executed by the ddl2 postback:

I have a question regarding disabling viewstate.
I know how to do this in the page, however if I disable in a master page will all child pages and controls be disabled through inheritance?
The sites I mantain are using way too much ViewState and I'd like to reduce that so the size of the page is reduced. I've done a lot to remedy this but I have an issue relating to DropDown lists that use AutoPostbacks.I have a dropdown list with a lot of list items and a good part of the ViewState usage is to hold the list item data. If I disable ViewState and set the AutoPostBack property to true, the page will post back and in the page load I am trying to repopulate the dropdown list with cached data. However, it seems that the SelectedIndexChanged event doesn't fire when EnableViewState="false".Is it possible to make this work without enabling ViewState for the drodown list?
View 6 RepliesI'm trying to add a row grouping row to my data-bound gridview. It works fine on the first response, but at the postback i got the "Failed to load viewstate" error.There is the code for the GridView's RowDataBound event:

Has anyone encountered while using Context.RewriteUrl in global.asax causes this error: Validation of viewstate MAC failed.

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.
I have a gridview which has a checkbox column which are set to automatically postback. When a checkbox is clicked, a partial postback occurs, and the associated record is displayed to the user (this is the required function).My problem is regarding when a user clicks a number of checkboxes in quick succession. I have got ajax request queuing working fine, so each checkbox postback is eventually dealt with. However as the gridview also postsback, it resets its viewstate on which boxes are checked, removing some of the boxes which the user may have checked.I've attempted to take off the viewstate on the gridview which seems to achieve nothing, neither does placing the gridview in a separate update panel.

My ViewState implementation causes "Confirm Form Resubmission" dialog to appear each time I press 'back' button, but when I create test site using microsoft's aspx their viewstate isn't causing such problems. What should I know to prevent my browser from showing "Confirm Form Resubmission"? I've found an interesting resource here, the problem described in terms of browser caching, if the page is cached than it won't make a post at all, now it is interesting how to make my page cachable by default.
View 2 RepliesNow 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:

View 1 RepliesI 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?

I have a website that uses windows integrated authentication. This is great and the way i want it, BUT, i now have a single .aspx file in that site, that i would like anonymous access to.
I am running this on IIS 6 on a windows server 2003.
How do i go about doing this, if i even can do it? web.config, IIS console or do i need to make a new site for this one file alone?
After adding personalization and authentication to my site, I was getting pitched out of my application( which is on a hosted server), and sent back to the log in screen . I disabled authentication to see if I could figure out what was going on. I found that
I was getting a system 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.
This error has been reported elsewhere [URL] so I made the following change to my web.config
<pages theme="Theme1" enableViewStateMac="false" enableEventValidation="false" viewStateEncryptionMode="Never">
This seems to have worked to a point, because with authentication DISABLED, I no longer get the error. But when I RE_ENABLE authentication, I get pitched out randomly back to the login screen. Time out is not an issue. It only happens when I move very quickly through screens that are doing a lot of postbacks.
This is the authentication stuff from my web.config
<authentication mode="Forms">
<forms name=".ASPXAUTH"
loginUrl="~/Login/Login.aspx"
protection="All"
timeout="3000"
path="/"
requireSSL="false"
slidingExpiration="true"
cookieless="UseDeviceProfile" />
</authentication>
<authorization>
<deny users="?"/>
</authorization>
I tried AutoDetect on cookieless as well. No change. I would appreciate ideas on how to troubleshoot this problem.
In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?
I have a website where different comapny and users can login. Till now I have not seen any issue on IE 6. But in case of one account, when try to login the website, users are getting security information "This page contains both secure and non-secure items.
I can reproduce the same easily for the same customer but not happening for any other customer. I have "ReportViewer" control (gets rendered as iframes) on the page.
In this scenario, whether user selectes "Yes" or "No" button, the home page with charts loads 30% and other controls remains invisible. Though I see same out in "View source" for this and other customers. We dont change anything much then the data and charts for the users. We use https for this website and has few links with "http" in page. But then this is same for all the users, but it happens only in case of one customer.

When debugging my website project I usually go to start options in the web project's properties and select 'Don't open a page' and 'Use custom server' with a url that's in my host file pointing to my local IIS.
Even when I do this though visual studio still spawns it's own Development Server instance every time I hit f5.
Also for web application projects that have shared ascx files for instance Visual Studio will also launch an instance of Development Server each time I debug the solutions for each for these projects. This results in a million instances of Development Server running on my machine at any given moment.
Is there any way to disable development server for a given project completely? Without pointing it to a localhost sub application?
