AJAX :: Call Viewstate In AutoCompleteExtender's GetAutoCompletionList Method?
Jan 4, 2011
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)
{
Is it possible to get viewstate only for related controls of update panel in asp.net ajax framework. I know that the browser sends all the viewstate during post back, even if we dont need the whole viewstate for ajax calls.
i have tried autocompleteextender using page method and without master page and its working. but now im try to put them into master and its not working. this is my code***********pagename.ascx
From 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
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.
In our application we have a scenario where we need to display a panel using modalpopupextender after performing an async call on the server. We were using the Show method for displaying the popup. It used to work fine without any async call. But when an async call was introduced during the request processing the popup is not getting displayed.
Can I call Ajax.BeginFrom from a custom helper method ?
AjaxHelper is not available in a custom helper method, so I tried to pass the "Ajax" available in ViewPage to Helper method while calling it, but then in method, BeginForm is not available on that passed "Ajax" parameter.
I am trying to call a simple method in my code behind using Jquery with Ajax. But I get a 404 not found exception everytime. Unfortunately this is a web forms solution. So I dont have all the perks of MVC
It does get into the javascript method and gives the alert but won't go into my c# method. My previous experience of using this Jquery method is in an MVC website. Is it compatible with webforms sites?
I have a web user control. That I load dynamicaly inside a modalpopup window using dynamic populate extender. User control has a external javascript file linked to it. Problem: I cannot make call to webservice method from this external javascript file. When I make a call -- servicename.methodname() I get servicename not defined error.
I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.
[System.Web.Services.WebMethod] public static string GetStateData(string state) { //this is where i want to call a javascript method "GetItems" }
I have a javascript method that retrieves some values for me and I want to get use one of those values in my web method
function GetItems() { var variable1= $("#<%=Item1.ClientID %> input:checked"); var variable2= $("#<%=Item2.ClientID %>").val(); return [variable1.text(), variable2.val(), variable2];}
I've searched for ways to call the javascript method from the web method but every time my search results in how to call a web method from javascript.
I did find this but it was done from the code-behind of a silverlight project and when I tried adding the correct reference to my code-behind it wasn't there
var result = HtmlPage.Window.Invoke("GetItems"); Is there a reference I'm missing?
I am developing web application and in application i need to make call of jQuery using .ajax(); method with datatype is set jsonp. Now all works well with limited data but problem start to occur when data size is increasing......
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?
I am trying to use Rounded Corner buttons in my ASP.NET website using AjaxControlToolkit's RoundedCornerExtender. When I use this on a Buton control, I get an error saying "htmlfile: Unexpected call to method or property access" to which I can Break/continue.
When I run the sites, it gives me an error "Unexpected call to mathod or property access".Here's the screenshot:
I have a GridView and a TabControl. On click on the row of grid, I store the EmpId in a hiddenfield in javascript. Now in Page_Init, I am trying to load a usercontrol for a EmpId stored in hiddenfiled. But I am not able to access hiddenfield value in the Page_Init. It display empty. If I have to load the usercontrol during Page_Init, then I have to access the HiddenField value first and it is give problem.
