I am using jquery so using ajax to post data, but for some reason when i click on submit, the page doesnt go from aspx to aspx.vb on the back side.here's my code -
new_class is my webmethod in the vb.net side. Now if i put an alert in the btnsave onclick function, i see the firstname value in the alert. But the page does not call the new_class function after that.
I have an ASP.NET MVC controller action with the following VB.NET signature:

If I'm trying to send an Ajax POST in jQuery to the ClosestCities action, what should my request look like? When I use the following code to POST to this action, in the debugger window of VS, position.longitiude and position.latitude are equal to 0.0 (0D):
I am using $.ajax call for download excel from .aspx page. But ajax throwing an error after Response.End. This is the code I used. Control is processing till Response.End() then alert(textStatus); giving parser error.

[code]... And it is supposed to read multiple lines from LimFile and send it to a string in VB.NET.Problem is that when I debug it, I see the string is there in full length. And when I split it with vbNewLine, it shows that theres only 1 line, aka nothing is split, like the newlines have been lost.
incorrect technical words used, I'm new to AJAX/Jquery.I have a function with AJAX in it. It is supossed to execute a serverside function, but it doesn't do anything. I have checked my code multiple times. I use similar code in a different location, and that one works fine.Here is the function with AJAX:
function pass_on() { hide_div("#outer_layout", 500); get_din();
I have a User Control which renders a simple drop downList into the page.By default, only certain values are returned depending on User Details, but the user may request a "full" list.I'd like this full list to be generated by pressing a reload button.Being new to .NET I am struggling to get this to work and not really understand the results I get when Googling or finding stuff on this site. Is Classic ASP I'd have made a page that renders this and called it using jQuery

I've found this link: [URL]..Using-jQuery but am unsure exactly what it is suggesting, mainly I think, because I use VB and don't completely understand how to convert that C# code there.Using .NET 2.0, jQuery and VB, does anyone have any suggestions on the simplest way to accomplish this?
I accept both C# and VB.NET If you visit this [URL].. and then click on the link like the image below you'll see in-line pop-up DIV which displays a busy status of Ajax callback before it displays the information. So, the information is not there yet until you click on the link.
I'd like to do the same but ASP.NET and jQuery. If there's any place to help me get started on the right track?
[URL] Response when viewing URL: {"Status":"OK","Message":"0","Info":"(none)"} Using JQuery how do I pull from that? I get how you do POST and sending but little lost has to how to pull from that. Do I use GET? Am I doing something like $.get("URL HERE"...?
The code below works "correctly" as far as sending the email address to the SaveEmail URL and it gets saved correctly each time I change the drop down. However it only outputs the "Successful" message once, no matter how many times I change the value in the drop down. The "data" that is returned is "Successful". I would like to show the message for a couple seconds, then fade it out. It works correctly the first time I change the drop down, after that the change happens and the value gets saved, but the "Successful" message doesn't display.
HTML code: <select ID='AgentEmails' runat='server'> <option value="test@test.com">TEST</option> </select><span id='SelectMsg'></span> What needs to be changed in my code to make this operate correctly?
I have a piece of JQuery AJAX that calls a VB.NET code-behind (class) that returns string data. It grabs some latest stats on a particular server. Now the code works, but the first time I press the refresh button data is returned and the alert "Refreshed" is shown on screen.
But if I press it again, the alert box "Refreshed" is shown twice, I click again three times! and on and on, until the time-out kicks in.It seems to be coming from the AJAX call and no where else. I'm at a loss at what could be calling this, I've tried deleting the data returned after success but no joy.
The following code populates a second dropdown when the first dropdown changes (i.e. cascading dropdowns). However, the Ajax call isn't firing, and I can't figure out why. I'm not getting any syntax or runtime errors. When in debug mode, the GetPlans action is never being called. The inner alert is never called, but the outer one is. To make matters worse, this same setup is working elsewhere in my app! Here's all the pertinent pieces (let me know if I've left out some important details):
var content = $("#content_layout"); //some code here content.load("claim_form.aspx?claim_no=" + file_number);
The claim_form.aspx has a drop down, and based on that drop down it should show the apropriate input fields. I set the index to be 1 and automatically load the first set of inputs. Here is some code to explain it better:
$("#request_type").change(function(e) { index = document.getElementById("request_type").selectedIndex; if (index == "0") {
i have a jQuery AJAX webmethod in ASP.Net that works perfectly fine when tested locally. but when uploaded to the server, sometimes it works sometimes it doesnt. when i debugged the code with firebug i see the the webmethod gets called but jumps right away to the error section of the ajax script.
jQuery code:
<script type="text/javascript"> $(document).ready(function () { //get current date
I am having a heck of a time with some very simple json. I have a very basic VB.NET webform which which writes out the contents of a datatable serizlized with JavaScriptSerializer.
This question is a following from another question I asked - Passing client data to server to create Excel or CSV File. I have a client page which builds a JSON object to send to the server, and I have server code which can parse that JSON object into an SQL command and end up with a dataset of required data.
I had originally been passing the JSON object to an .asmx web service which would return a JSON object containing my data. Now I want to go in a different direction and have the data returned as a .csv file.
I understand I can try to put my JSON object into a query string and call my .ashx page, but the JSON object could get large, so I'm trying to use the Request.Form of a POST.
My question, and lack of understanding, is in how to use jQuery to post to the .ashx page and have it return the .csv file to the client. If I navigate to the .ashx page directly (and modify the page to hard code the passed data), I get the .csv file returned to me no problem (i.e I get the prompt to open/save the file). If I make a POST to the .ashx file from jQuery and send my JSON object through, I get a response which contains the data in a string, rather than getting a .csv.
So, is there something I am missing, or am I just trying to achieve something that I can't or shouldn't be doing? I'd thought about passing my JSON object to a .asmx web service which would store the JSON object into a database and return an ID, and then use window.location to browse to the .ashx with the ID as a query string parameter to then generate the .csv file, but I thought there might be a way to avoid that middle step and do it with the POST.
This is failing because it's calling the Post method (where "covered" can't be empty) instead of the Get. I tried decorating the Get with <AcceptVerbs(HttpVerbs.Get)>, but it doesn't change the outcome.how do I get it to use the Get? I realize I could change the names to not be ambiguous, but I want to know why it won't pick the Get if I'm only passing "bpid".
I have a bit of strange behaviour in an asp.net web application that involves the session state being lost.
Process A user logs into the application and the session is set. They then fill out 1 field, and the application then does an AJAX POST to a .asmx web service. Within the web service, I am using a HttpWebRequest to grab data from another server.
This data is then output to the browser.A few more fields are then filled in, and the data is then again Post to the same web service via an AJAX POST.
Access <asp:table> table rows added by javascript in asp.net webform . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.If I have a <HTML> table or an <asp:table> control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?
I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.there was a way to include these new rows in the post-back, the same as any client-side user input?
We're working on a big ASP.NETVB.NET website project. I need to populate three dropdownlists. To last two are independent of the previous ones. The population data comes from an SQL Server. I'd have no problem doing this with code-behind with post back but we don't want any PostBacks so I started to develop this in AjaxjQuery.
I have been thrown in at the deep end with an existing VB.NET project at work. I have never used VB.NET before so I am struggling a little. Does anyone know how to solve the following.I need to pass an instance to client side and then pass it to a shared method in order to access instance methods from when the shared method.The starting point is a fileupload control within the HTML of my Contacts.aspx file:
The onchange event calls a javascript method, see below, this uses AJAX PageMethods to called a Shared method in my code behind This is the script code which is in my Contact.aspx file

If anyone knows the solution please could they update the code as I probably won't be able to understand if you just give a description. I just hope I am along the right tracks.
I have a form which contains a fairly large number of values. I am currently submitting with a POST method, but I wish to convert this to do it with jQuery via AJAX. I have been experimenting with converting my code-behind "save to database" function into a Web Method. I am using a two-step function method, firstly preparing all the variables from Request.Form("parameterName") and then passing them all into a "saveData" function as follows:
[Code]...
From the post mentioned above, I can see I can send this string, but how do I process it server-side when recieved? The article implied that HttpContext.Current.Request.Form("parameterName") should work, but it doesn't... I'm guessing because I need to access it from the txtQuery variable..
I'm trying to use an ajax auto complete extender, but it's not working. I put a break point on the GetCompanyNames method in the web service, but it doesn't even hit the break point.

I have a problem that my jQuery don't load or something when i'm on the contentpages.When i click on the link that should load the jquery,it only works at my startpage (Default.aspx). And when i click at the same link that is placed in my footer on any other contentpage, nothing happens. So i guess something is wrong with the paths or the loading of my scripts.Here is my scripts in the masterpage .
