Does anybody know how to implement this new feature of the MVC 2 RC?
Here is verbatim what ASP.NET MVC 2 Release Candidate Release Notes says:
"...Buttons in a form can specify that they do not cause validation logic to run. The default is that every button in a form causes validation logic to run, and if validation fails, the validation logic blocks submission of the form. Enabling validation selectively for buttons lets you create forms .
I have three listboxes, lst, lstA, and lstB, in which lstA is an instance of lst. The problem I have is that whenever I remove an item from lst, the same item in lstA is also removed. I have tried assigning a different ID to lstA to no avail. see my code below:

I have a simple 2 tab panel setup with 2 validation groups. My problem is that my buttons fire both validation groups.

<ContentTemplate>

I am having some problem with Jquery validation.
In my application i am using jquery validation plugin..I am using Updatepanels and i am validating using
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(ValidateMyForm);
and ValidateMyform will validate on each button click...
var objPost = args.get_postBackElement();
if (objPost === null || objPost === undefined) return;
if (objPost.type == 'submit') {[code].....
Here I want to get back the page to normal stage(like after a full page postback)...even though after async postback the validation is still active...it should not get back to normal and its throwing errors if i enter something wrong...this is because the page is not fully refreshed on asyc postbacks...I just want get the like the normal after each asyc post back...
I tried using submit and reset to reset the page but its became to normal..the validation is still active...I have no idea what to do..
In a ListView, I have a CustomValidator set up to validate a field whenever a button with CommandName="Delete" is clicked.
<ItemTemplate>
<asp:TextBox ID="NameTextBox" Text=<%# Eval("Name") %> runat="server" />
<asp:Button ID="DeleteButton" Text="Delete" CommandName="Delete" ValidationGroup="Delete" runat="server" />
<asp:CustomValidator ValidationGroup="Delete" SetFocusOnError="true" Display="Dynamic" OnServerValidate="CustomValidator_ServerValidate" runat="server">You can't delete this.</asp:CustomValidator>
</ItemTemplate>
However, the error message is never displayed and the processing continues. What's strange is that the custom validation method is called, finds the field, and properly sets up e.IsValid to false. It does not matter whether I check Page.IsValid or not, because the error message is not displayed anyway. It works if I remove the CommandName="Delete" from the button.
With Google I found the following solution, which seems to indicate someone has had a similar issue:

But I want to make sure that this solution is the way to go. I mean, is custom validation really not supposed to work with a delete button in a databound control, seriously?
i am having an mvc 2 application in which i have a form that contains two buttons
[Code]....
Now my requirement is to disable validation when the user clicks `Add` button. But validate when the user clicks `Save` Button.
I have several buttons on a page, but have assigned some validators and AJAX validator callout extenders to one button in particular. However, the validator callout extenders seem to be firing even if I press a different button. I thought this was the point of setting a TargetControlID (for the valiator callout extender) and a ControlToValidate for the validator itself!

I have a website on live server, and I have a the same website on local machine. both using the same database. Some links are in Arabic.
The links are ok on live server, but it is corruptted on local machine.
Both Live server and local machione are hosting the website using IIS 7.
I think that the only chance is related to IIS configuration but how??
I am using a .net blog application (BlogEngine.net) and to skin it you have to create a new masterpage. I have most of it working but my dropdown navigation is not working. Here is my page that isn't working: [URL] Then I decided to just take my styles and code and put on a normal page to see how it looks and it works as expected. [URL]
View 39 RepliesApart from blocking other threads reading from the cache what other problems should I be thinking about when locking the cache insert method for a public facing website.
The actual data retrieval and insert into the cache should take no more than 1 second, which we can live with. More importantly i don't want multiple thread potentially all hitting the Insert method at the same time.
The sample code looks something like:
public static readonly object _syncRoot = new object();
if (HttpContext.Current.Cache["key"] == null)
{
lock (_syncRoot)
{
HttpContext.Current.Cache.Insert("key", "DATA", null, DateTime.Now.AddMinutes(5), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null);
}
}
Response.Write(HttpContext.Current.Cache["key"]);

I am using IIS Url rewrite to convert urls from /mypage.aspx?q=value to /page/value.html.
Everything works fine during the first call to the page but on postbacks the url is transformed into
/page/value.html?q=value
when using asp controls such as GridViews, Pagers or Custom Controls.
As a result the Server returns a 404 Error and i can see the corrupted url on the browser's address bar.
This problem was observed when i wanted to change the page of a gridview using a pager.
I would like to save some data for use after a page postback. Here is an example of what I'd like to do:
Partial Class TestPage
Inherits System.Web.UI.Page
Private _CategoryID As String = ""
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
_CategoryID = "ABC"
Me.ViewState("CategoryID") = _CategoryID
Else
_CategoryID = CType(Me.ViewState("CategoryID"), String)
End If
End Sub
End Class
I've tried both session variables and view state. The page loads fine initially, but on postback I get the following error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> 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.
What am I doing wrong? How can I save this data for use after postback?
I am having a problem with postbacks on my live server.I have added a button to my page with postbackurl="google.com when I press the button it is doing nothing but If I put response.redirect("google..

I have a page, where I dynamically add textboxes within an updatepanel with a button.click event. Those are common telephone, fax, email, etc.. Now I put in some values, store those in Session with Arraylist and go to next page. Here, there is a button to go back to previous page. Ive managed to recreate all those textboxes on Page_Load event, using if not page.ispostback, then.. Now, this problem is driving me crazy. When I load my page, put in some values, add as many textboxes, as I want and go "Next", its ok. Then I go "Back" and everything is recreated and I see as many values within textboxes, that I created. But when I do this for a 2nd time, I can only see recreated textboxes without values. Ive spent some time searching for a simple solution, or an advice. But with no success. I could post some code here, but its a bit long and complicated. But if necesarry, I will.
View 4 Repliesi am currently working on a webform that has several dynamically populated dropdown lists. this works just fine, however, i have other web controls that require to have a postback..and at the time the page postsback, it reloads my dropdownlists, reseting whatever option i had chosen...
what can i do to resolve this?
I am generating an html flow into Update Panels in a content ASPX page (VB.Net 2008 Professional w/ SP1). These include EDIT anchor tags that call a javascript function which calls __doPostBack(target, args); so I can interact with the code behind. This all works fine except on some of the postbacks the connection with the browser just seems to get closed prematurely and suddenly the webpage displays a directory listing. When debugging it, it only happens sometimes, at different places for the E and D options below but not for the V or AddPost or AddArticle. I am just stepping through E or D and suddenly the web page show a directory listing. (What is that? Is the connection crashing? Is the page suddenly redirecting to the base directory because it crashed?)

I have a value variable as: Dim Tax As Decimal = total * 0.075
i would like this value be available to sub procedures on the page even after a postback?
At present i am able to persist that using session InProc mode. except that i cant use either stateserver or sql server as the HTTPPostedFile is not serilizable. i can't use viewstate either for the same reason. Is there any work around to persist that httppostedfile across postbacks for session modes other than inProc or viewstate?
View 4 RepliesI have a website that serves all its pages using a single 404 page. it displays hotel profiles form business and depending on different profile levels offers more or less functionality and information.
Through the DB a masterpage is selected and usercontrols are applyed to that.
I have a contact page like this : 404.aspx > masterpage.Master > contact.ascx
My form action looks like this default.aspx?404%3bhttp%3a%2f%2fwww1.testsite.co.uk%3a80%2fcontactus
and when I click the button this where I send up with an error "Validation of viewstate MAC failed" error.
I have read stuff on these for 4 hours but still have no idea where to start.
Do I need to
Catch the form action URL (postback URL) in the baseclass and change it back to [URL] - If I do this are the form firled values still intact
Do i need to do something to change the form.action url before the page is built, if so is this done in the masterpage preinit event as this is what the form tag is
What I know works is that the usercontrol is aware of the postback, but not the form values.
I want to be able to add a 404 based contact us form on any one of 1000s of profiles and be able to catch the values. Idearly I would like to do this in the codebehind of the usercontrol as this keeps the code seperate
I am sure this must be possible and normally I can work stuff out, but here I am totally stuck. I am trying to do this in VB.
