View 1 RepliesFrom client side, I need to call a server method that is not static. For example, I got the following user control ucData (private instance of code-behind) that is Databind in the load event. The server method I need should return ucData.IsValid(). So it can't be static
View 1 RepliesI did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().

This cannot change. There is no way to convert Business and Data layers to static.

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 2 RepliesI have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
$("#Name").on("blur", function() {
if (Name != "" && Name != null) {
var options = {
type: "POST",
url: "ApplyNow.aspx/CheckName",

This thread is more about learning, actually I have a web service which just returns string. I have been calling this service from code behind and updating lable with the string received from the web service.
Now I want to call web service using JavaScript. As far as I know, I have to add <asp:ScriptManager..../>. Second I have to add [ScriptService] to the web service.
But I don't wat to add <asp:ScriptManager..../> and [ScriptService].
Is there any way to call web service using javascript without adding <asp:ScriptManager..../> and [ScriptService]
Also, I am kind of lost in SOAP, JSON. I am not getting where I actually use SOAP, JSON. Using <asp:ScripManager../> and [ScriptService], I actually didn't see use of SOAP, JSON.

I am using VS 2008. I am using Ajax Autocomplete extender to populate a textbox. usually there is a webservice method which populates data into the autocompletion list... but in my case, the data is coming via an instance method...
At the time of doing the autocomplete, the autocomplete calls the method, the data is getting lost in the page postback..My situation is such that I cannot use a static method to get data from database, since there is already a public instance method.I am using the technique of calling GetAutocompletionList without using a WebService method.
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetAutoCompletionList(string prefixText, int count, string contextKey)
{
// want to use static viewstate here ..
