MVC :: Returning A Function In JSON?
May 26, 2010I would like to return an function in some JSON. How can I stop my function being output as text (how can i stop it being wrapped in quotation marks?).
eg: [Code]....
In script the value of name is just a string. Is there some object I can set name to that will wrap my script and emit as script not a string?I want to do this to better control the "remote" rule of jQuery validate. I have my own dataannotationmodelvalidator for it and its doing this atm:
[Code]....
Which is working fine for the most part except I can't get the value of 'name' to be a function. It comes out as a string. Alternatively is there someway to control what JSON serializer this thing is using alternatively. We need a wrapper function so you can do something like:
name = Emit("function(){ return $(this).val(); }")
and have it come out as script not a string.
MVC JSON Actions Returning Boolean?
Sep 20, 2010I had my ASP.NET MVC actions written like this:
//
// GET: /TaxStatements/CalculateTax/{prettyId}
public ActionResult CalculateTax(int prettyId)
{
if (prettyId == 0)
return Json(true, JsonRequestBehavior.AllowGet);
TaxStatement selected = _repository.Load(prettyId);
return Json(selected.calculateTax, JsonRequestBehavior.AllowGet); // calculateTax is of type bool
}
I had problems with this because when using it in jquery functions I had all sorts of error, mostly toLowerCase() function failing.
So I had to change the actions in a way that they return bool as string (calling ToString() on bool values), so that thay return "true" or "false" (in the qoutes) but I kinda don't like.
How others handle such a case?
Returning A JSON View In Combination With A Boolean?
Apr 13, 2010What i would like to accomplish is that a partiel view contains a form. This form is posted using JQuery $.post. After a successfull post javascript picks up the result and uses JQuery's html() method to fill a container with the result.
However now I don't want to return the Partial View, but a JSON object containing that partial view and some other object (Success -> bool in this case).
I tried it with the following code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(int id, Item item)
{
if (ModelState.IsValid)
{
try
{
[Code].....
However I don't get the HTML in this JSON object and can't use html() to show the result. I tried using this method to render the partial as Html and send that. However this fails on the RenderControl(tw) method with a: The method or operation is not implemented.
JQuery :: Get JSON Call To MVC Controller Not Returning Data
Nov 25, 2010This is probably something simple. The following JQuery call is executing and calling the controller. The controller is executing correctly. I used the sample data that's commented out to verify that the templates were working also. However, the success function is not executing in the browser. Any thoughts or other ways I can debug this?
<script type="text/javascript">$(document).ready( function(){ alert("Here"); @* var myData = [ {first: "Jane", last: "Doe"}, {first: "John", last: "Doe"} ]; *@ $.getJSON( "/User/Filter",function(myData){ $("#myDataTemplate").tmpl(myData).appendTo("#itemContainer"); } ); alert("there"); }
);</script>
//Controller
public ActionResult Filter() { var myData = this.repository.GetAllUsers(); //return Json(myData); return Json(myData, JsonRequestBehavior.AllowGet);}
JQuery UI Autocomplete WebService Source Returning JSON?
Nov 29, 2010I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.
There are several issues:
1) The autocomplete function is not firing
2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception
3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return.
4) I am not at all certain that this code will accept JSON data that comes back from the service
Here is the code:

WCF / ASMX :: Windows Communication Foundation Service Returning Xml / Json Data?
Aug 25, 2010I Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.

Alternate Row Color In A GridView Using Pure CSS?
Mar 9, 2010I want to alternate rowcolor in a GridView, using pure CSS, ie: I don't want to use asp.net themes; I'd rather not have to use jQuery, or define define AlternatingRowStyle-BackColor on each gridview (unless there's a reason I must). Here's my CSS (that isn't working):
.gridView {font-size:11px
}
.gridView tr:nth-child(even) {background-color: #FFF}
.gridView tr:nth-child(odd) {background-color: #FFCC00}
.gridView tr:nth-child(even) td {background-color: #FFF}
.gridView tr:nth-child(odd) td {background-color: #FFCC00}
(I included the .gridView {font-size:11px} just to confirm I am using the proper CssClass.) Is this not possible, or am I doing something wrong.

Invoking WebMethods With XmlHttpRequest And Pure JavaScript?
Jun 22, 2010I have what should be a relatively simple task that's frankly got me stumped. I've researched it until my brain is fried, and now I'm puntingHere's the scenario:I have an ASPX page (Q2.aspx) that is decorated with the WebService,WebServiceBinding, and ScriptService attributes. That page contains a method, GetAllContacts, that is decorated with the WebMethodattribute and returns a string containing JSON data. (For what it's worth, the pageitself contains no other controls or functionality.)I have an HTML page that contains JavaScript which uses the XmlHttpRequestobject to invoke the GetAllContacts WebMethod on the ASPX page and transformthe JSON data into an HTML table. I have verified that my Web.Config file contains the appropriate protocol handlersfor HttpGet and HttpPut in the WebServices section under System.Web.webServices.
I have verified that my Web.Config file contains the ScriptModule entry under theSystem.webServer.modules section, and that it matches the appropriate documentation.
However, when I view the HTML page in a browser, the following occur:The web request goes through, but the results are for the unprocessed HTML from the ASPX page.The GetAllContacts method is never invoked, as evidenced by setting a breakpoint in its code.The code to invoke the Web service, however, is invoked, and the JavaScript callbackfunction that is invoked upon request completion is properly invoked.
It appears that the JavaScript code is largely set up correctly, but for some reason that is completely escaping me at this point, the HTML page will simply not execute the WebMethod on the ASPX page, and simply returns the page as though it were a plain HTML GET request. Clearly, an HTML document can't be evaluated by JavaScript's eval function, which brings me to my problem. (Also note that the JSON data appears nowhere in the HTML that's returned.)I am, frankly, baffled. I've looked at dozens of Microsoft articles, StackOverflow posts, CodeProject articles, and who knows what else. My code looks like it's okay. But I know better. I'm missing something simple, stupid, and obvious. I just need someone to point it out to me.Below you'll find the ASPX page code and the HTML code, in the hope that they'll shed some light.ASPX Code

Generate Membership Password Hash In Pure TSQL
Feb 17, 2011I'm attempting to create a pure t-sql representation of the default SHA-1 password hashing in the ASP.Net Membership system. Ideally, what I would get would be this:
UserName Password GeneratedPassword
cbehrens 34098kw4D+FKJ== 34098kw4D+FKJ==
Note: that's bogus base-64 text there. I've got base64_encode and decode functions that round-trip correctly. Here's my attempt, which doesn't work: SELECT UserName, Password, dbo.base64_encode(HASHBYTES('SHA1', dbo.base64_decode(PasswordSalt) + 'test')) As TestPassword FROM aspnet_Users U JOIN aspnet_membership M ON U.UserID = M.UserID
I've tried a number of variations on the theme, to no avail. I need to do this in pure T-Sql; involving a console app or something like that will double the work. So if anyone can supply what precisely the syntax should be to duplicate that password from the ASP.Net membership stuff

Get Clean / Pure HTML From ASMX Web Service Call?
Oct 12, 2010I am trying to use jQuery .load() to get straight html from a asmx web service:
$('#target').load('MyService.asmx/GetHtml');
In .NET code, GetHtml() returns as string:
[WebMethod(EnableSession = false)]
[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Xml)]
public string GetHtml()
{
return "<span>Hi</span>";
}
That returns:
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/"><span>Hi</span></string>
Notice that the string is encoded. With that encoding, $.load doesn't work right. The displayed text actually has the tags shown.
How can I get the WebMethod call to return just this?
<span>Hi</span>

Jan 9, 2010i have two buttons, which point to some onclick-methods in my code-behind file. inside these btn_click-codes i want to start adding pure html-code to my page, which was told to me in this forum having done by using ascx-files. note: there would be no code-behind in case of using the ascx-files.
however i do not see a possibility to load these ascx-files within btn_click-code? how to do?
in order to give you an idea of my html-code i have pasted two of them here:
