How can I go from an SQL statement to AJAX?I know this is a broad question so here is what I am trying to do and what I have tried.
I have using asp.net(vb) connected to the database and put the information in a dataset and datagrid.(I don't want to use a datagrid anymore)
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();

View 2 RepliesI 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"...?
View 3 RepliesI 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 -
$(document).ready(function() {
$("#btnsave").click(function() {
var firstname = $("#" + '<%=firstname.ClientID%>').val();
$.ajax({
[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.
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.
jQuery code:
$('#AgentEmails').change(function() {
var NewAddress = $('#AgentEmails').val();
$.post('SaveEmail.aspx', { email: NewAddress }, function(data) {
$('#SelectMsg').html("<b>" + data + "</b>").fadeOut();
});});
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.
function RefreshServer(btn,div,id,ip) {
$('#aRefresh'+id).html("<img src=images/refreshServer.gif border=0 align=absmiddle />");
$("#"+btn).click(function() {
$.ajax({

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):

I have a main page that loads a content of a div:
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 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:
<asp:FileUpload ID="DocUpload1" runat="server" onchange="CallMe();" />
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
[Code]...
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.

View 1 RepliesIn VS2010 I have VB.NET codebehind aspx pages and I'm using Ajax multihandleslider extensions to filter search results on numerical values.
Fistly, the multihandle sliders don't display in the designer... I have to remove the slider targets tag:
In order to make it display in the designer... this isn't so much a big issue but an annoyance.
I am displaying items in a given category. So I get the max and min prices for all items in that category and assign the sliderextension max/min values appropriately.
This works fine until... I change the item category and go get a new max/min value for the slider control. I set the max/min values, then I set the target textbox values each to the corresponding max/min values.
The slider handles don't repaint (or init?) properly Like say for example my initial min/max is 1/100 if I do a full postback and change the max value to 1000 then the slider bar (correctly) stays the same size but the handle appears WAYYYY to the right off the page and I have to scroll to it. When I click it, it shoots back onto the slider bar.
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 am trying to service AJAX requests with a method in my .aspx page. For some reason I am not getting the data returned that I want.

I'm creating a reporting web page as part of a standard VB.NET web application. The page is data driven, with jquery making calls to a web service local to the application to get values of elements that are dynamically created in the DOM. Ultimately these dynamic elements and their values are all wrapped up in a JSON object, so that part of the client side is fine.
Right now, I can pass that JSON object to a method in the web service which creates an SQL Data adapter from the values and queries a database. My ultimate goal is to have this client JSON data be used to query the database and construct an excel file to send back to the user, or failing that a CSV file.
It's my understanding (from working with PDF file generation) that this type of function can only be done on the server side of the web application, not even from the web service (i.e. I can't have the web service return an array of bytes and have JavaScript/jQuery present that as a file).
So, how do I go about this? Now I have my JSON object on the client side, where should I be sending it, how, and how do I go about returning my file?
I've read about either storing the JSON in a hidden field and having the server take the elements value and go from there, or using AJAX to send the JSON to the server just before a postback is made to fire off the server-side function to run the query and return the data.
I just need a little guidance, and a little help understanding where to use the hidden field, or what I am actually doing with the pre-postback AJAX call.

I have a form with 2 dateTimePickers and a SHOW button which gets data from an sql server database and displays it in a DataGridView. this works ok. I also have an EDIT button which brings up another form with textbox and comboBox controls displaying this one record. I want to be able to click in the DataGridView to select a Name and then click on the EDIT button to bring up the selected record. I don't know how to pass the ID as a parameter to this second form. Apart from that the EDIT button works, in the sense that I hard coded the ID (32 or 35 etc.) and it brings up the appropriate record. But how do i pass the selected ID. [Code]
