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.

//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?
$("#Name").on("blur", function() {
if (Name != "" && Name != null) {
var options = {
type: "POST",
url: "ApplyNow.aspx/CheckName",

With i display the buttons from the database, i can not call a method from code behind! I can't either use their properties "onclick" to call i method i created in the code behind.Is there a way to do it ?
I have a web application I am working on that uses a master page. I am reading I create a LinkButton in the codebehind file for the page. When the link is clicked on the webpage, it does not even call the method defined for it. I have tried multiple ways of doing this and nothing seems to work for me.

I have repeater inside a updatepanel in UserControl.
