• Posting a form and redirecting to action ASP.NET MVC

  - by dean nolan

  I have a navigation bar that uses JQuery to move between 4 stages of signup process. However I need to make sure everything is working with JS disabled. So I have these 4 link images at the bottom of the page and I need so that if one is clicked it posts to the current action so I can save all the form data and then redirect to the next stage. The redirect is easy enough as I will just pass a parameter in the route or form but I don't know how to post the method using just action links. I could put 4 different submit buttons with different classes for the image backgrounds etc but this feels wrong. Any ideas?

• How can I add GET variables to the end of the current page url using a form with php?

  - by zeckdude

  I have some database information that is being shown on a page. I am using a pagination class that uses the $_GET['page'] variable in the url. When you click on a different pagination anchor tag, it changes $_GET['page'] to a new number in the url and shows the corresponding results. I have sort and search features which uses the $_GET['searchby'] and $_GET['search_input'] variables. The user enters their search or sort criteria on a form that is using GET. The variables are then put into the url allowing for the correct results to be shown. The problem I am having is that whenever I click on a pagination link, it adds that to end of the url and erases the search or sort GET variables. The same thing happens when I submit the search/sort form. How can I add GET variables to the end of the current page url using the anchor tag and search/sort form?

• CrossPost access to data

  - by Craig

  Hi, I have a search form on a page that posts back to itself and shows the results, all works fine. I now have a requirement to put the same search form on the site home page. This needs to post back to the search form and run the findResults code. Using the PostBackURL parameter on the home page form's submit button I can hit the search page ok. However, when using the following code in the Page_Load section of the search page I hit the problem of not being able to access data from the posting page as I get the following error message on the line starting "yearList.SelectedValue....": "'Site._default1.Protected WithEvents yearList As System.Web.UI.WebControls.DropDownList' is not accessible in this context because it is 'Protected'". '################################# '# Handle form post from Home page '################################# Dim crossPostBackPage As Site._default1 If Not (Page.PreviousPage Is Nothing) Then If Not (Page.IsCrossPagePostBack) Then If (Page.PreviousPage.IsValid) Then crossPostBackPage = CType(PreviousPage, Site._default1) yearList.SelectedValue = crossPostBackPage.yearList.SelectedValue getAvailability() End If End If End If As I didn't declare yearList Protected, I don't know where to change it or how to. Any advice would be appreciated, Craig

• logging a facebook user ID to a local database from a facebook 'like'

  - by Azzam

  I am creating a site that allow users to vote on webpages similar to digg.com. Users login with 'facebook connect' and logged in users can submit, vote, comment, etc and these details appear in their profile ie. number of submits, votes, comments, etc. I have also added in facebook 'likes' to the system. I would however like to be able replace the internal voting platform with facebook 'likes'. What I would like to be able to do is identify when any of the site users vote on a facebook 'like'. Although a facebook 'like' can be made outside of my site I am only interested when a logged in user submits a 'like' so this can contribute towards their stats. Is this possible, if so how? Thanks Azzam

  I have created a simple app with a page having a server side form, three fields and a button that submits and performs two operations - 1) adds the form fields to the database table 2) sends an email. Now everything works fine on the web browser on my machine but when I access the app through my mobile, the page does not seem to work. the UI and all are set but the button click functionality doesnt seem to be working and also the label which is set after a successful submit is already visible and showing the "thank you" message.

• What does it take to prove this Contract.Requires?

  - by John Gietzen

  I have an application that runs through the rounds in a tournament, and I am getting a contract warning on this simplified code structure: public static void LoadState(IList<Object> stuff) { for(int i = 0; i < stuff.Count; i++) { // Contract.Assert(i < stuff.Count); // Contract.Assume(i < stuff.Count); Object thing = stuff[i]; Console.WriteLine(thing.ToString()); } } The warning is: contracts: requires unproven: index < @this.Count What am I doing wrong? How can I prove this on an IList<T>? Is this a bug in the static analyzer? How would I submit a bug report to Microsoft?

• Re-setting CSS code for form buttons

  - by WebDevHobo

  I used a CSS reset to reset some commonly-used items. The code is this: html, body, div, h1, h2, h3, h4, ul, ol, li, form, input, fieldset, textarea { margin: 0; padding: 0; border: 0; font-size: 100%; } ul {list-style: none outside none;} img, fieldset {border: 0;} h1, h2, h3, h4 {font-weight: normal;} em {font-style: italic;} strong {font-weight: bold;} I know there's YUI and Meyer's reset, but I use this one. Now, the problem I'm experiencing is that I can't get the submit buttons to look normally again. I could ofcourse remove the input from the list and be done with it, but I'd like to know how to get it back, since I might need that in the future.

• Building an XML editor in java and RichFaces

  - by Mark Lewis

  Hello I'm building an XML editor using the above technologies. In essence, I want to read in a whole XML file to a java object, and refer using this object to each element in the XML node tree (grouped into entries) to display the content locked, have separate padlocks for the user to click to 'unlock' an entry allow overwriting of the data, and to submit this entry. 'Add entry', 'Duplicate entry', 'Delete entry' are also functions I'd like to add. I already use dom4j and XPath to access areas of the XML file so some of the work in theory is already done. Given the above, I was going to use these two together with inplaceInputs to allow the user to edit the XML and JSF validators to check the data coming in. Is this the best way to approach this problem, or is there a more straightforward route than XPathing a whole record? I started looking at jaxb but I'm new at java and jsf but I've got the feeling I won't be by the end.. Thanks

• Unobtrusive jQuery and Rails with AJAX and form validation

  - by bogumbiker

  Hello, I am looking for a way to call successfully custom function from submitHandler to do proper ajax post. Here is my custom function: jQuery.fn.submitWithAjax = function() { this.submit(function() { $.post(this.action, $(this).serialize(), null, "script"); return false; }) return this; }; Before using validate plugin I had following which worked fine: $(document).ready(function() { $("#my_form").submitWithAjax(); } Now I have added the validation part and have no idea how to call my custom submitWithAjax function?? $(document).ready(function() { $("#my_form").validate({ /*Validations - works perfectly!! */ }, submitHandler: function(form) { /* $("#my_form").submitWithAjax(); - this works but introduces recursion */ /* how to call custom subitWithAjax() ????? */ } }); }) Thanks!

• Html Attribute for Html.Dropdown

  - by kapil

  I am using a dropdown list as follows. <%=Html.DropDownList("ddl", ViewData["Available"] as SelectList, new { CssClass = "input-config", onchange = "this.form.submit();" })%> On its selection change I am invoking post action. After the post the same page is shown on which this drop down is present. I want to know about the HTML attribute for the drop down which will let me preserve the list selection change. But as of now the list shows its first element after the post. e.g. The dropdoen contains elements like 1,2,3,etc. By default 1 is selected. If I select 2, the post is invoked and the same page is shown again but my selection 2 goes and 1 is selected again. How can preserve the selection? Thanks, Kapil

• Getting values from Multiple Text Entry using Pygtk and Python

  - by Webrsk

  On a click of a button named "Add Textbox" it calls a function which creates a single textbox using (gtk.Entry) function. So each time i click that button it creates a textbox. I have a submit button which should fetches all the values of the text boxes(say 10 textboxes) generated with the name of "entry". It works for one textbox but not for multiple. In php we can create dynamix textboxes mentioning as an array name=entry[]. Do we have similar functionality in python ? Enviroment : FC10 , Glade 3 , Python 2.5 , GTK.

• IE9 Acid 3 test?

  - by yuval

  Does anybody know if Microsoft is planning on having IE9 pass with 100/100 on acid 3? The current version of IE9 gets a 68/100 on the test (can be viewed here, main site here). What did IE8 pass with? What about IE7? How does it compare to other modern browsers such as Safari, Firefox, and Chrome? Please submit useful answers, not opinions on how bad IE is, I don't like it either. Thanks a bunch!

• ASP.Net double-click problem

  - by David Archer

  Hi there, having a slight problem with an ASP.net page of mine. If a user were to double click on a "submit" button it will write to the database twice (i.e. carry out the 'onclick' method on the imagebutton twice) How can I make it so that if a user clicks on the imagebutton, just the imagebutton is disabled? I've tried: <asp:ImageButton runat="server" ID="VerifyStepContinue" ImageUrl=image src ToolTip="Go" TabIndex="98" CausesValidation="true" OnClick="methodName" OnClientClick="this.disabled = true;" /> But this OnClientClick property completely stops the page from being submitted! Any help? Sorry, yes, I do have Validation controls... hence the icky problem.

• null values from listbox, are not evaluated in the model binding of ASP.NET-MVC

  - by Jorge

  The model validation doesn't evaluates the attributes linked to listbox values if you don't select at least one of them. This way is not possible to do a model evaluation using DataAnnotations in order to inform required values. The controller: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using TestValidation.Models; namespace TestValidation.Controllers { [HandleError] public class HomeController : Controller { private SelectList list = new SelectList(new List<string>() { "Sao Paulo", "Toronto", "New York", "Vancouver" }); public ActionResult Index() { ViewData["ModelState"] = "NOT EVAL"; ViewData["ItemsList"] = list; return View(); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(MyEntity entity) { if (ModelState.IsValid) { ViewData["ModelState"] = "VALID"; } else { ViewData["ModelState"] = "NOT VALID!!!"; } ViewData["ItemsList"] = list; return View(); } public ActionResult About() { return View(); } } } The View: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TestValidation.Models.MyEntity>" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <h2> Validation Test</h2> <p> <% using (Html.BeginForm()) {%> <fieldset> <p> ModelState: <%= Html.Encode((string)ViewData["ModelState"])%> </p> <p> <label for="Name"> Name:</label> <%= Html.TextBoxFor(m => m.Name)%> <%= Html.ValidationMessageFor(m => m.Name)%> </p> <p> <label for="ItemFromList"> Items (list):</label> <%= Html.ListBoxFor(m => m.ItemFromList, ViewData["ItemsList"] as SelectList)%> <%= Html.ValidationMessageFor(m => m.ItemFromList)%> </p> <p> <label for="ItemFromCombo"> Items (combo):</label> <%= Html.DropDownListFor(m => m.ItemFromCombo, ViewData["ItemsList"] as SelectList)%> <%= Html.ValidationMessageFor(m => m.ItemFromCombo)%> </p> <p> <input type="submit" value="Submit" /> </p> </fieldset> <% } %> </asp:Content> The Model: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace TestValidation.Models { public class MyEntity_Validate : ValidationAttribute { public MyEntity_Validate() { this.ErrorMessage = "Validated!.

• What is your contribution to open source projects?

  - by Yuval A

  I was always wondering about this seemingly utopic world of open source. Assuming the vast majority of users here are professional software engineers which need some sort of income source, I assume most of us hold stable, money-making jobs. So who are the key players in the open source community? Who are the people which devote their precious time to these projects? What is their benefit? Are the majority just people who see a bug, fix it, submit, and forget about the project? Or are they people constantly involved in the process of building the product? How do you find yourself contributing to open source projects?

• input type text and onKeyDown not working under IE

  - by dygi

  Hi there. I am writing a WWW application, it has to run under IE. I have the problem with the code that runs under FF, but i can't get it running under IE. // JS code function test() { if (window.event.keyCpde == 13) window.location.href.ssign("myPage.php"); } I've tried some similar ways around window.location and location.href, also document.location. I've read that IE has problems with that, so i ask for a solution. The goal is, that page reloads after typing in some text into <input type='text' name='item_code' onKeyDown='test()'> and click enter. So the result is similar to pressing submit type button below the text input. Within IE it reloads the same page and nothing happens. In FF it correctly works.

• ASP.NET MVC & Detached Entity won't save

  - by Justin

  Hey all, I have an ASP.NET MVC POST action for saving an entity on submit of a form. It works fine for insert but doesn't work for update, the database doesn't get called, so it's clearly not tracking the changes, as it's "detached". I'm using Entity Framework w/.NET 4: //POST: /Developers/Save/ [AcceptVerbs(HttpVerbs.Post)] public ActionResult Save(Developer developer) { developer.UpdateDate = DateTime.Now; if (developer.DeveloperID == 0) {//inserting new developer. DataContext.DeveloperData.Insert(developer); } //save changes - TODO: doesn't update... DataContext.SaveChanges(); //redirect to developer list. return RedirectToAction("Index"); } Any ideas would be greatly appreciated, thanks, Justin

• jTabbedPane opens different tab on loading

  - by Santeron

  Hey mates, First of all I'm using netbeans as my IDE and I don't know if this is causing it. When I run my program (even if I have build it and run the .jar) I think it selects the tab that was previously selected (before quiting). So if for example I close the app with the third tab selected, it starts up with that selected again. Is there a known solution for this? The selectedIndex property on the jTabbedPane is set to 0. Shouldn't this property be the default onLoad value? Thx in advance, Jimmy PS. BTW for some reason it didn't submit my question in Opera (?)
