I have the following javascript:
$.post("/Authenticated/DeletePage/" + PageId);
showStatus("Page deleted...", 10000);
I would like to instead pass showStatus() text that is returned by the $.post() call, rather than hardcoded text. How do I do this?
I've got a view model that has some text properties. And I use Html.DisplayFor to display them on the screen. But those text data won't be post back, so in the case of failed validation, the returned view won't have those data. How do I handle this kind of situation?
View 2 RepliesI am trying to build a site that will display a word ("Synset" in my code) from a "function call", (ultimately the word will come from another database but I'm ignoring that part for now). The user will click one of 4 radio buttons deciding if the word is "positive", "negative", "neutral", or "can not be determined". Then the user clicks "Save" the word is saved a MS SQL database, the function is called displaying a new word and the process is repeated.
So far I have been able to get this to mostly work by using the code below. The problem is that the function is called and the correct word displayed when the page loads the first time, when I click a radio button and then the "Submit" button, the word and value from the radio button are saved to the database but then no new word is displayed. The text just disappears. The new word is created, as I can see that new words are saved to the database when i click submit.
I'm thinking the issue might be because I'm binding the text attribute of the label I'm using to display the word to the sqldatasource, because it's probably trying to display the text from the database?
I've tried putting the code that gets and displays the new word in FormView1_PageIndexChanging() and submitButton_Click() and neither work.
I've tried to just call Response.Redirect("Default.aspx") in submitButton_Click() and this displays the word but nothing is saved to the database.

How can I call a URL ex.
[URL] and get the values returned from it in VB.NET ?
What am I missing here. I just want to pull the first one returned from row.detail in an MVC2 view, how would i do this without a foreach loop? This code currently works, but i just want the first one listed. I know this may be simple, but i am drawing a blank.
if (Model.App != null)
{
foreach (var row in Model.App.Instructions)
{
<input type="hidden" value="<%= row.Detail %>" id="ixd" />
}
}
For now, I just want to use HTTP POST to send json to asp.net mvc2 controller.Since the JSON is actually a list of JSON objects, and each of them has different fields & length, so it hard for me to make up a input model.So I want to know is there a way for me to post JSON without model/ajax to a controller in ASP.NET MVC2?
View 2 RepliesProvided wsdl from link below:
http://www.2shared.com/file/zfTUDRl3/poccrm.html
I've been given merely a wsdl above from client, without any further information given, to make a call using c# code but i added as web reference, used the codes below and the client side detected my request and they've returned us proper format xml too, but i cant retrieve it in the string array from the method returned. the "stringset" has became null instead of array[10]. Can anyone give a hint what kind of web service call is it, since it is not using the simple and classic way to invoke?

callerItem.StartDate = "20-01-2010";
stringset = caller.SE1I2001(callerItem); //here i get null for stringset, but client received the request and returned us value
//same result even I use wsdl.exe converted it to a class file

View 1 RepliesI wonder if I have any other method but a hidden field to post a JSON object to the server on full postback.
Imagine you have a form (with textboxes, checkboxes, etc) and you need to post a json string when the user post the form. This means, I would post all the form values + the json string but I can't come up with any solution but a hidden field.
Is it safe to send a POST to a web method with a JSON string containing a clear text version of a password for authentication?Who could sniff that password on the way from client to web method? I saw some posts a while ago on "salting" a password - is that something you do in JS on the client side and then "unsalt" on the server?

I have problem with JSON, MapRoute. If I click on "save" I always get Page / Index Page instead of / SendForm. I dont know why, in javascript it says url: '/ page / sendform'. But the problem is at Global.asax.cs,

"{controller}/{action}/{url}",
new { controller = "Page", action = "Index", url = UrlParameter.Optional });
But there is still problem at the url, which shows Controller, Action that I dont want to .. I have a url / lang / seo-url /. How can I achieve by clicking on the Save, it should call SendForm method instead of Index ..

I have a Page that expects a POST Request and returns some JSON. Essentially it's an .ashx Page, but that doesn't really matter.
When using jQuery, I would use jQuery.Post with "json" as dataType to simply make the POST request and get an object back. However, for the current project I mainly use ASP.net AJAX and I don't want to add jQuery just for the call.
For ASP.net AJAX, I only found information on how to call a "traditional" web service though, which means adding a asp:ServiceReference to the ScriptManager and having a "real" Web Service at the end.
Is there a simpler way to make a POST call to a Page? I could live with getting the raw JSON and then manually eval()ing it, but I don't want to create a full asmx web service (deploying them on SharePoint is a bit painful, and my ashx handler works fine)
This 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);}
I'm trying to make a call to a JSON ASP.NET web service with .NET.
It is ok when I send " { county : 'whatever' } ", but I get a 500 Internal Server error if I try for example " { county : 'It's ok' } ".
[Code]....
I've found some posts with examples but I cannot make it work:
" { county : "whatever" } " and " { "county" : "whatever" } " also works.
But either of " { county : "It's ok" } ", " { county : "It's ok" } " or any other combination that contains a single quote in the variable work.
How can I send a single quote inside a JSON call?
