using the bing map API, can I make a server-side call and get lat/long for a given city? I can do it on the client side using JavaScript, but I need something more robust in this case and want to use the server side.

I have a div called address which as a textarea. When I click a hyperlink, it toggles the div up and down. After clicking a an asp.net button the div collapses which is fine, but I noticed the url turns from [URL] to [URL] and now the toggle does not work. Here is the script:
$(document).ready(function () {
$('#myAddress').click(function () {
ShowHideAddressBox();
});
$('#arrowIndicator').click(function () {
ShowHideAddressBox();
});
});
function ShowHideAddressBox() {
var str = $("#myAddress").text();
if (str == "Hide") {
$("#myAddress").html("Click here");
$("#arrowIndicator").attr("src", "/Shared/Images/misc/arrow_state_grey_expanded.png");
}
else {
$("#myAddress").html("Hide");
$("#arrowIndicator").attr("src", "/Shared/Images/misc/arrow_state_grey_collapsed.png");
}
$('#checkAddress').toggle('normal');
}
The server-side button click just sets some values in a couple textboxes. In my master page, I have the following line as well:
<asp:ScriptReference Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Name="MicrosoftAjax.js" Path="http://ajax.microsoft.com/ajax/3.5/MicrosoftAjax.js" />
When an ASPX page needs to make a call to a potentially long-running operation (lengthy DB query, call to a remote webservice, etc.), I use RegisterAsyncTask, so the IIS worker thread is returned to the pool, rather than being tied up for the duration of the long-running operation. However ASMX webservices don't have a RegisterAsyncTask function. When an ASMX webservice needs to call a potentially long-running operation, how can I implement the same behavior as RegisterAsyncTask? Note: the ASMX webservice is implemented as a script-service: returning json to a direct jQuery/ajax call. Therefore, I cannot use the "BeginXXX" approach described by MSDN, since that implements the asynchronous behavior within the generated client-stub (which isn't used when calling the webservice directly via ajax). EDIT: Adding source code: implemented the BeginXXX/EndXXX approach listed in John's answer. The synchronous "Parrot" function works fine. But the asynchronous "SlowParrot" function gives an internal server error: "Unknown web method SlowParrot"

I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?

View 1 RepliesI am trying to use the Bing Maps Ajax Control to plot pins of locations stored in a database to the bing map on a web page. All the locations are geocoded and the lat longs stored in the database. I am using ASP.NET (C#), but can't figure out or find any tutorials on how to go about doing this. All I can find are articles on how to import shapes into a map from either GeoRSS, Bing Maps, and KML.
I have used (and paid for ;o) the excellent control from Simplovations to do alot of what I need to do, namely working with my data as normal in the code behind, getting a DataSet of my locations and plotting the points to the map. It has been great, but I want to know how to do it with out using a third party control. My main reason for wanting this is to be able to cluster my pins and hopefully learn a bit of Javascript along the way. Does anyone know how to do this or can point me to any tutorials or articles online that can help me on my way. I have been searching the net for days now and can't find anything :(
How to call server side method from. js?
View 2 RepliesHow to call JavaScript function from server side
View 2 RepliesI have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding.
I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions.
But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config.
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
ResponseFormat = WebMessageFormat.Json,
RequestFormat= WebMessageFormat.Json) ]
How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?
Or put another way, this may be incorrectly worded, can an endpoint have multiple bindings?

View 1 Repliesn many websites I could see that when you click on a button for the first time you will get an update progress and then get the new data. Second time you click, it does not go to server side and shows the data from the client side. Eg : News section in yahoo.com. Like this, in some websites I could see onmouseover on a word or image they show you a hover menu type control with meaning of a word or some other details.

Here I saw how to do it with ajax, this system, however, breaks down with ajax: I can't use it at all.
