I have a user control having a pagemethod. I want to call this pagemethod from my page using jquery's ajax() method?
View 5 RepliesI'm calling a static Page method via javascript that takes between 5s and 10 min. I'd like to give my user the choice to either continue waiting for the request to complete or not, and use window.setTimeout() to check back every 30s.
I've tried both location.href = '/newpage.aspx' or firing a button's click handler (which does similar redirect) to redirect the user prior to completion of the page method, to no avail. I can immediately send user to a simple html page, but a redirect to any aspx page involving server-side appears to block. When the page method finally completes, the redirect does succeed.
Is this:
a browser issue? If all modern browsers support at least 2 concurrent requests per domain, why wouldn't this work?
a framework limitation? a desirable design pattern or even possible? I've checked, and after redirecting to an HTML page, the original request continues processing (db updates, no problem).
I need to set a couple of Session vars by calling a PageMethod using jQuery.
The client side js looks like this:
function setSession(Amount, Item_nr) {
//alert(Amount + " " + Item_nr);
var args = {
amount: Amount, item_nr: Item_nr
}
//alert(JSON.stringify(passingArguments));
$.ajax({
type: "POST",
url: "buycredit.aspx/SetSession",
data: JSON.stringify(args),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () {
alert('Success.');
},
error: function () {
alert("Fail");
}
});
}
and the server side like this:
[System.Web.Services.WebMethod(EnableSession = true)]
public static void SetSession(int amount, int item_nr)
{
HttpContext.Current.Session["amount"] = amount;
HttpContext.Current.Session["item_nr"] = item_nr;
}
only, it seems that the Session vars are not set. When I try to Response.Write out the Session vars, I get nothing. I get no errors, and I can alert out the values passed from the onclick event, to the js function, so they are there.

I wonder if I could call a Function in code behind from jquery(client side), not to trigger a jquery function from code behind? I can not use linkbutton and button it must be a A-tag otherwise it loose it's purpose
View 3 RepliesI have a LinkButton that I need to perform a click on to cause a postback. The actual link target is:
javascript:__doPostBack('ctl00$c1$btnRefreshGrid','');
Clicking the link does perform the postback, as verified by a breakpoint in the code-behind. Also pasting javascript:__doPostBack('ctl00$c1$btnRefreshGrid','') in the address bar of the browser works with the same effect.
I've tried the following with no effect at all:
__doPostBack('ctl00$c1$btnRefreshGrid','');
$('#ctl00$c1$btnRefreshGrid').click();
$('#ctl00$c1$btnRefreshGrid').trigger('click');
eval($('#ctl00$c1$btnRefreshGrid').attr("href"));
I've tried using both <%= btnRefreshGrid.UniqueID %> and <%= btnRefreshGrid.ClientID %> to generate the selector.
I have created an WCF data service in a new asp.net web application and i want to call this web service from another web application using jquery, but it always returns null.

Note that [URL] works in the browser but since the jquery call is from localhost:3410 i assume its a problem with cross domain.
I have been reading that i should use jsonp for this, but i have a hard time figuring it out.
How to secure an Action filtered with Authorize method from a jQuery call? I have this Authorize filter and it work's cause users are redirected if not logged-in. But after logging-out then accessing previous open pages that needs authorization, they weren't redirected at all. This jQuery is initialize when a button is clicked,
jQuery.post(
"/controllername/IsUserActive", {
}, function (data) {
if (data){
$('#div_user_active').html(data);
{ else {
$('#div_user_active').html('Not Active');
}
}
);
then calls this Action method.
<Authorize()> _
Function IsUserActive() As Boolean
Return True '<<---this keeps returning even users are already logged-out.
End Function
Overall, I wanted ajax(jQuery) to update/read a portion of the page but gets redirected if not authorized.
