Microsoft's Implementation Of Viewstate Not Causing "Confirm Form Resubmission" Message
Feb 1, 2011
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.
I'm developing ASP.NET applications and stuck with a "problem" relating to resubmit behaviour. I'm controling the re-submit using a counter in form submit event which disables the submit if it's already been posted. My application is a 3 step workflow and when the 3rd step is shown the transaction was submited from step2 to step 3. What's my problem? Well... i want to avoid the user to resubmit the data by pressing the F5 or all other possibility. I don't want to disable the key because may be workarounds. I'm wondering if i can remove the post data in a HTTP module that runs after the render was completed and right before the response is sent to the user.
I have a simple sign up form, user fill that form and press submit and then he refresh the page, the form re submit again and data enter in database twice. How to prevent?
I'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:
Private Sub AddGroupingRow(ByRef eRow As GridViewRow, ByVal Css As String, ByVal ColSpan As Integer, ByVal Txt As String) Dim cell As New TableCell() cell.ColumnSpan = ColSpan cell.CssClass = "Spacing FieldCell" cell.Text = Txt Dim row As New GridViewRow(-1, -1, DataControlRowType.DataRow, DataControlRowState.Normal) row.CssClass = Css row.Cells.Add(cell) [code]...
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.
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.
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).

For an MVC 2 app that relies on many partial views and almost exclusively uses Ajax for POSTs/GETs, what would be the best way to implement the setting, passing, retrieval and display (using a JavaScript modal) of these messages?
My forms all POST (by way of jQuery $.ajax) to actions that return partial views (html) that are used to update a in the "success:" part of the $.ajax function.
I was hoping for some sort of mechanism in the master view that could "listen" for any messages that any of these partial views might be "delivering"--through their ViewData, for instance.

I have one text box with a range validator, and a submit button.I also have a confirmbuttonextender and modalpopup.The popup still displays even if there is a form error!
How does this work with validation, since the popup displays when the button is pressed and not when the form is validated correctly?
I am having trouble with my login form. In the current design I have a login ascx which I am trying to use for the user to login from both the home page (as a box on the left) and on the login page that I will use as part of a checkout process.My login.ascx is a partial view using straight out of the box code for simplicity...
[Code]....
What I am trying to achieve sounded rather simple until I tried to implement it. I can get the login page to come right up if I use Html.EditorForModel rather than Html.RenderPartial, but I can't use Html.EditorForModel on my main page because the main page isn't bound to a model.
What I would like is to show login form on main page. If login fails show the validation summary just like on the Login view. I could live with the user being redirected to the login view, but this wasn't what I had in mind.
How can we add a web page or a Windows Forms to the Outlook mail so that when I send a mail to a person he/she should be able to enter the data in the controls on the mail form? The user should also have the ability to save the data directly from the mail, instead of opening my web or a Windows application and update the data.

Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated -
"Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. "
