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.

[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"...?

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

View 2 RepliesI have a gridview in asp.net/vb and it is bound to a list - so there's no standard sorting available. I've found this jQuery plugin for sorting tables: [URL]. The plugin requires <thead> and <tbody>. The problem is, that my gridview only renders the <tbody>.
I've already tried
DataList.UseAccessibleHeader = True
DataList.HeaderRow.TableSection = TableRowSection.TableHeader
But this changes nothing.
My gridview markup:
<asp:GridView runat="server" CssClass="grid" ID="DataList" AutoGenerateColumns="False" AllowSorting="True" ClientIDMode ="Static">
<Columns>
<asp:BoundField HeaderText="SomeHeaderText" DataField="SomeDataField" />
<asp:BoundField HeaderText="SomeHeaderText" DataField="SomeDataField" DataFormatString="{0:dd.MM.yyyy}" />

I Need a working example of a cascading drop down list box written in vb.net for my ASP.Net MVC application. I tried converting three examples written in C# but can't seem to figure it out and I have given up.This is my first .net application so I'm a newbie. The biggest problem I'm having is just don't understand the java script code in the views.
View 3 RepliesI'm trying to solve a problem regarding types of list. First of all I have a stored procedure in my DB which does a select of a single column and I try to proceed it in my app in VB. By making a method function I declared a DataTable that loads through the SqlCommand(with the CloseConnection behavior). After that I publicly declared a List(Of String) which needs to be populated with the rows/items from the stored procedure that is on the way. Below is my snippet of the code:
Dim dt As New DataTable()
Try
If conn.State = ConnectionState.Open Then
[Code]....
It's LPrefix = collection.Cast(Of String)() where I get an exception error telling me that I can't really convert it. The old fashion way is to iterate with for/for each loop but that's not what I want for best use of performance especially if the list will have thousands of rows from a single column. So basically, I want to insert those items from that DataTable to the List(Of String) without For/For Each loop.

I need to create a VB.NET application which playes a song at a time from a predefined list of song.Basically, there is a list of Mp3 files which is completely hidden to the user and there are 5 buttons on the screen.

The intention is to convert an IList of custom objects to a string equivalent comprising each element in the Ilist. Unfortunately I can't seem to find a way to get the underlying data of the custom object, and of course as in the above example, using object simply gives me a string of types definitions, rather than access to the underlying data.
I have a music player, and i can add songs to a play-list, but i was wondering if you can make only the song name show up, and not the entire file path?
View 3 RepliesHow 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();

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.

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?
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 -
$(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?

There are going to be quite a lot of these loops to do what I want can anyone offer any help or a better way to go about doing this? Note that I want the values list to return 10,10,10,20,20,20 so that lines that have 10 should be added first and lines with 20 then afterwards.

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() {

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):
