MVC Return To Page On Error With Fields Populated?
Jan 13, 2011
I am starting a new project in Asp.net MVC 2.I have been mostly a webforms developer and have limited exposure to Asp.Net MVC and hence this is probably a noob question.
My situation is as follows:
I have a create page for saving some data to the DB. The view for this page is not strongly bound / typed - so the way I am extracting the data from the view is by looking at the POST parameters.
Incase there is an error (data validation, etc), I need to send the user back to the previous page with everything filled in the way it was and displaying the message.
[Code].....

I am putting a C# asp.net web form together that has a number of fields that we want to ensure data is inputted in them. I have added the RequiredFieldValidation control, but I am unsure what to put in the Button_Click event. I want the click event to check the fields and if not filled in, preserve the fields that already have data and then return the page data with the missing fields so that they user can take corrective action.

I'm writing a small web application in c# and i'm running into a small problem.
Basically, on page_load() my backend MySQL db is queried to bring back the user data, and that is then inserted into the textbox controls as below:
[Code]....
Now the problem occurs when the RequiredFieldValidator kicks in. In my form processing function, I call Page.IsValid(), it fails and displays the required message next to the required fields.
I was wondering if there is a workaround for this, or a better way to go about what i'm trying to do.

I have the following code which simply gets data from a table and populates the questions_lb listbox with items. I have a button on the page, which when clicked, should write (on submit) the selected state of each of the items. The code below writes the text values of each of the items fine however it always writes the li.Selected as False even though i have selected items from the list. Note that you can select Multiple items from the list. Does anyone have a clue why its not writing 'True' for an item that is selected on submit?

I'm trying to return an error page indicating that the user couldnt be found and therefore I throw a HttpException with status code 404, however for some reason it wont redirect to the error page? - Is there some sort of trick to handle error pages with JSON that I should be aware of? My current code:
public ActionResult Details(int id)
{
User userToGet = _session.Query(new GetUserById(id));
if(userToGet == null)
{
throw new HttpException(404, "User not found");
}
DetailsUserViewModel userToViewModel = AutoMapper.Mapper.Map<User, DetailsUserViewModel>(userToGet);
return Json(new
{
HTML = RenderPartialViewToString("Partials/Details", userToViewModel)
}, JsonRequestBehavior.AllowGet);
}
Update - Some more code:
// MyJs.js
function openBox(object) {
$("body").append("<div id='fadeBox'></div><div id='overlay' style='display:none;'></div>");
$("#fadeBox").html("<div style='position:absolute;top:0;right:0;margin-right:2px;margin-top:2px;'><a id='closeBox' href='#'>x</a></div>" + object["HTML"])
$("#fadeBox").fadeIn("slow");
$('#wrapper').attr('disabled', 'disabled');
$("#overlay").show();
jQuery.validator.unobtrusive.parse('#mybox') /* Enable client-side validation for partial view */
}
// List.cshtml
@model IEnumerable<MyDemon.ViewModels.ListUsersViewModel>
<table style="width:100%;">
<tr style="font-weight:bold;">
<td>UserId</td>
<td>UserName</td>
</tr>
@foreach (var user in Model)
{
<tr>
<td>@user.UserId</td>
<td>@user.UserName</td>
<td>@Ajax.ActionLink("Details", "details", "account", new { id = @user.UserId }, new AjaxOptions() { HttpMethod = "GET", OnSuccess = "openBox" })</td>
</tr>
}
</table>

Created an solution containing several class libraries (domain, contracts, etc, etc) and an Asp.Net MVC3 project. Created a database in my local sql server (2008) and ran aspnet_regsql.exe to create the relevant membership and authentication tables. (Though I did not create any code yet that uses it, and plan to just implement the standard forms and membership authentication.) However, when I click on the "Asp.Net Configuration" button in VS (2010), it open the Asp.Net Web Site Administration Tool, but with an error that say "An error was encountered. return to the previous page and try again." (of course there's no "previous page). Only reason i want to use this is actually to create two roles, admin and client. Guess my problem is not knowing where this tool get it's connectionstring from. At present, I got the following in my web.config

How can I configure ASP.NET/IIS to show custom error pages (i.e. a nice friendly error page), but to still return a 404/500 status code so that google does not try to index the page? I have tried setting the Response.StatusCode to 404, but then the nice error page does not show anymore.

I am calling a file download action from javascript:
$elem.click(function() {
window.location.href = 'MyController/MyFileDownloadAction';
});
The controller returns a file:
[code]...
This action has a pretty high likelyhood of throwing an exception (or at least not being able to return the file).
Due to the nature of the application (which contains a lot of dynamic content), I can't really redirect to an error page in this situation. The current page needs to stay open somehow.
So I'm ideally looking for something like a javascript pop-up, but afaik this isn't going to be possible since I don't know any way to return a javacript instruction in a non-ajaxed controller call. If I display an error page I need to force it to open in a new window some how. Is there any possible solution to this problem?

I Have a problem here with Visual Web devoloper 2010 , When I click the "Asp.net Configuration" , the browser doesn't open the Web Site Administration Tool but the icon does appear in the notification area , on right clicking the icon it opens up the Web Site Administration Tool in the browser and displays "An error was encountered. Please return to the previous page and try again."
On the other hand I don't have any issues using "Asp.net Configuration" with Visual Web Devoloper 2008

I'm using Ajax to dynamically populate a DIV. I have each page content stored in XML files as CDATA. When a user clicks on a link from the navigation bar, the Ajax loads the XML for that particular page, parses it, and populates the DIV with it's content.
Everything is working GREAT, except for one thing. I have a jQuery modal popup whose markup is loaded from that page's XML file. The .js and .css files from the jQuery plugin are all loaded, and when this is HARD CODED (i.e., not loaded from XML), it works fine. But when it's loaded from the XML, the modal doesn't work.
When the page is loaded from the XML file- What the page is supposed to do is load the HTML from the XML file, which it does, and there's a hyperlink that when clicked, it's supposed to create the modal popup window. Instead, clicking on the link does NOT fire up the modal popup window.
When the page is hard coded- it does everything it's supposed to do.
A live example is at:
http://mikemarks.net/clientSites/tabras/
Click on "The Band", and at the bottom you'll see the hyperlink called "Demo". Clicking on that should bring up a modal popup window, but instead as you can see it just takes you to the top of the page.
Below is my markup (notice the div id="copy", which is the placeholder for my HTML content that's loaded from the XML file), my Ajax JavaScript code, and my XML file (which is shown as the markup that's loaded into the div id="copy").
<div id="leftTwoThirdsColumn">
<div id="menu">
<ul class="menu">

My page includes a button and a GridView bound to a LINQ data object which is bound to a table. when the page loads the gridview gets populated with the data and all work well. The button has an empty method, when I click the button I get en error message "Intenet explorer cannot display the web page" I put a break point at the begining of the method listed below but I get the error message before it gets there. If I remove the gridview than the button works well.

I'm populating my nodes from SQL 2008. My Defauld.aspx is also devided into frames. leftmenu is frame on left. topframe is frame on top and mainframe is frame right center. In my leftmenu frame LeftMenu.aspx display a SQL populated treeview. if I click on the child node it opens Home.aspx in the Main Frame. This is pretty straight forward. My problem is that i can't get the value of that populated node over to a textbox on my Home.aspx page that is displayed in the mainframe on the right. My code is as follows:
void PopulateSubModule(TreeNode node)
{
SqlCommand sqlQuery = new SqlCommand("Select * From SubModule " + " Where ModuleID = @ModuleID");
sqlQuery.Parameters.Add("@ModuleID", SqlDbType.Int).Value = node.Value; [code]....

We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...

I am using ASP.NET MVC for developing a web site. I am using jquery for AJAX functionality. In the action methods, I want to return some error to signal that the input is not correct or that the action could not be performed. In such error cases, I expect the jquery ajax error handler to be called and I can take appropriate action in there. I have not found a way how to do this. Following is my action method.In error cases, what should I be sending from an Action in order to get the jquery error handler triggered?
public ActionResult AddToFavourites(int entityId, string entityType)
{
if (!Request.IsAjaxRequest())

I have a data driven asp.net website with frames on the top, left, right and center screen. If a page generates an error on any of the frames, I want to redirect the whole site back to the Default.aspx. Currently, when a frame page errors in one of the frames, that frame gets the error pages. Site is URL.... Is this something that can be handled?

I've got an ActionMethod that returns a JsonResult object and this isn't returning data to the calling jquery function. I have used wget to send and receive raw data to it, and I've discovered that when the object dataset is empty, it returns a value fine and the wget return is
HTTP request sent, awaiting response... 200 OK
Length: 78 [application/json]
Saving to: `filename'
but when there is data in the object dataset I get an internal server error:-
HTTP request sent, awaiting response... 500 Internal Server Error
2010-03-05 13:21:16 ERROR 500: Internal Server Error.
This is a dataset of objects being returned - are there any common "gotchas" when doing this?

I had to resort to native sql, which showed the error, as the not null fields are there in the table.
