Populate DropDownList In Asp.net 2.0 Using Ajax?
Aug 6, 2009
I am new to Ajax and have a rough idea about Ajax. I am developing a website having a feedback page in which, i want to populate the state/city DropDownList box depending upon the value selected in country DropDownList box.
I have seen some examples downloaded online but they are not working in my application due to many possible reasons, some of them may be the feedback page in my application is a content page, the web application is asp.net 2.0 web application, i don't have any additional ajax tools or scripts installed.give me the solution that should work with asp.net 2.0 web application (in VB.NET) and the feedback page is a content page. I don't want to add custom controls. I want to do it straight away with javascript or vbscript using XMLHTTP object.
After everything is set right with Ajax. What if the browser doesn't support Ajax? What should i do in such case?

I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table

I am using a PropertyGrid control. There are two things I need to be able to do.
1. I need to be able to access Ajax controltoolkit components and populate the propertygrid with the properties from the Ajax control toolkit.
2. I need to be able to do the same with WebUI components.
The basic part, populating the propertygrid with a control, I understand how to do - -
What I don't know is what to import or how to access what dll (for the Ajax Control Toolkit and the Web UI controls), in my Winforms project to be able to do this.

Ok, everything is 'functionally' working with what I am attempting to accomplish and once again, I am sure this is something dumb, but I cannot figure out how to do this one thing.I have an edit form for an entity, lets say a car. This 'car' can have 0 - many passengers. So on my edit form, I have all the fields for the car, then a list view showing each passenger (partial). I also have a 'add new passenger' button that will render a new partial view that allows you to enter a passenger. This has a cancel link and an add button to submit an Ajax form. When you add a passenger, the passenger is automatically added to the list, but I need the enter passenger form to go away. I have tried using the onSuccess and onComplete functions to hide the div that the form is in, but both render just the partial view HTML elements (white screen, text) and not the partialView in the context of the entire page.

I basically need to do this, but unfortunately my hosting provider doesn't give me "Full Trust" so I can't run threads. Is there a way to do this using AJAX?
//Updates Information in Database
Thread threadFind = new Thread(LoadFind);
threadFind.Start();
Response.Write("Send old information to users"); I don't want my users to have to wait at all for a response, so I can send them the old information. However, while they are on the page I want another thread (or something that works like a thread) to update the information for the next user that visits.

The middleware that manages talk between the mainframe and our app is blowing up randomly. It's a "such and such attempted to read/write protected memory..." error.The vendor is saying there we must be running some unmanaged code (I feel they're trying to worm out of it). I know VB's entirely managed, but does anyone know about the server portion of AJAX? Is there any server side javascript stuff that occurs before it actually gets into the .NET framework?

I have a DropDownList in MVC which grabs a SelectList initialized and populated by a controller. The goal of the specific page that said list resides on is to reply "You have selected option X" immediately to the user without refreshing (using Ajax).The problem I'm running into is that for some odd reason, while the dropdown renders properly and even posts back correctly, any attempts to add new options or modify previous response messages are in vain.
My View:
<script type="text/javascript" src="../../Scripts/MicrosoftAjax.js"></script>

I have worked on .NET 2.0 technologies and now that I want start learning newer technologies, I am currently very confused on how to proceed.
New technologies I am considering consist of AJAX, Workflow, WCF and WPF
Here is my dilemma:
1. Where should I start first?
2. Which technology would allow me quicker understanding?
3. Is there any specific sequence to this learning?
I understand the questions might be stupid; however, this would help me concentrate on one instead of all over the place and archiving nothing.

I have to use VB.Net. Microsoft provides black magic tools (in the Visual Studio IDE) for making AJAX work, but using these seems hopelessly complicated and documentation for these tools covers only the simplest examples. By contrast, writing the scripts myself seems much easier, and I will understand what is going on.
So my question is, is it possible to write my own AJAX javascript (creating the XMLHttpRequest object, etc.), and have the server-side function be written in VB.Net instead of PHP?

I am working on adding some ajax controls for either a hover menu or popup control. But when I do I get the following code.<System.Web.Services.WebMethodAttribute()> <System.Web.Script.Services.ScriptMethodAttribute()> _
Public Shared Function GetDynamicContent(ByVal contextKey As System.String) As System.String
End Function I am trying to find out exactly how to code against this function. I am at a bit of a loss with regard to the WebMethodAttribute, and ScriptMethodAttribute, one would think I could delete one or the other. I watched numerous videos by MS and others and this code behind is not covered.
If someone could point to some tutorials, MSDN, white papers, or web sites where this is used, or in a project or something,
