Using JQuery to call a WebMethod

Question

I am having trouble getting inside my Search WebMethod from my JQuery call. Maybe someone could help to point me in the right direction.

I also packed up everything

Answer 1

You need to do the following (C#):

• The WebMethod must be public static
• It must be decorated with the [WebMethod] attribute
• You need a ScriptManager on your .aspx page
• Set the ScriptManager's EnablePageMethods="true"

And here is some sample javascript:

$().ready(function() {
    $(yourDropDownList).change(LoadValues);
});


function LoadValues() {
    PageMethods.YourMethod(arg1, CallSuccess, CallFailed);
}

function CallFailed(result) {
    alert('AJAX Error:' + result.get_message());
}

function CallSuccess(result) {
    //do whatever you need with the result
}
