View 1 RepliesI need to develop a login where user can login from his facebook account. When user login first time, an auth dialog should open from facebook asking to user for access permission and than it should move to one of my page where I can retrieve user email address and first name & last name through his facebook access token. How to achieve this?
View 1 RepliesIn my facebook canvas applikation, i store the access token in session. (I use ASP.NET MVC)
But i want to store the access token in a database along with the facebook user id that i can save different access tokens for different facebook users accessing my application.
So when i query the facebook user id and if it doen't return any access token, i request permissions and get the access token for that user.
How do i access the Facebook UserID for the user accessing my canvas application before doing any authentification?
i have made a gridview which contains three fields, two textboxes and one combo box. ComboBox fetchs data from table(SQL) and when a combox box triggers, data related to combo must be added in two boxes. i did this throw another button, but i want this to be trigger directly when it clicks..
View 1 RepliesI'm trying to create a basic application, i created facebook application before but everything has been changed.
I looked every where to create a basic application, but now i'm getting mad because there isn't any working sample. Because of the changed links, facebook api changes, facebook wiki changes i couldn't find a working copy.
write a basic app that gets permission to write user name to screen in facebook developer toolkit asp.net. I looked computerbeacon.net, codeplex, and some other pages but i couldn't succeed.
Edit: I' m adding some screenshots and some codes, it will may be you to find my problem.

View 1 Repliesi created a mathod facebookInfo(string username,string password) ,so i received username and password but after receiving its not possible to login at server side,because ther is only one way to connect to facebook using facebook api ie.
facebookservie.ConnectToFacebook();
and its open IE browser,so there is any way to login automatically and get session,using any javascript or nay other way at server side using ASp.net in C#.
if i want my facebook connect site to access user information about a facebook user, is it necessary for that user to be logged in?

I am using ASP.NET Callbacks (that implements the ICallbackEventHandler) and in the handler, I try to set a value of the text box:
txtName.text = "Test";
but this value is not set. Is this a limitation with callback? It appears I cannot do much in a callback handler other than sending back a string to the client side (ofcourse I can access the Session etc)
I have an asp.net page. I'm using a jquery library to open a modal window on link click. Within this modal window I'm loading another page. After i make update within this modal window I need to send a callback to "Parent" page. if I call function from this window I'm getting the error it couldn't find function. Window.opener.functionname also not working.
here is an example of my code
$(function () {
$('#ControlId').click(function (e) {
e.preventDefault();
$.ModalWindow({
bgColor: '#3333cc',
url: 'default.aspx'
});
return false;
});
return false;
});
});
Is there any way how to send a callback?
I have been trying to figure this our for far too long and I cannot get my head around it. Every example I have seen seems to be far more complex that I need.
I have a web service in my project (.asmx). I want to call it very simply from a button on a webpage.
Click
Run service asynchronously
return control back to webpage (web
service running in background)
I have a page in which the Grid View is loaded using ICallbackEventHandler Asyncronously(Callback feature of ASP.Net).The stored procedure to populate the Grid View is time consuming.Once the page is loaded,the Grid View appears on the page after 7-10 secs.The problem is that in the mean while if there is a PostBack from any control (example if a Button is Clicked) on the page,then in that case the Callback isterminated and the Grid View is not loaded.Did any one came across this situation?
View 2 RepliesIn asp.net is it a requirement to rebuild the whole page during every callback? For example my web page is split into three distinct areas and I have an update panel for each area. Lets say I want to update the third area, do I have to bother with any processing of the other two areas?
For example lets say there is a grid view in area two. The update panel in area three callbacks to update its content. Do I have to rebind the grid in area two?
I have a masterpage that contains a user control. The usercontrol uses callbacks for various operations. However, every time a callback is issued from the user control it is propagated down to the pages that inherit from the master page. How do I determine the id of the control that issued the callback so that I can stop these callbacks from destroying the state of the pages?
View 1 RepliesI am building a web application in ASP.NET using C#.NET which sends a SMS using clickatell.I am trying unsuccessfully to receive a status back from clickatell by creating a CallBack Page called ClickatellCallBack.aspx Here is the codebehind of the Page:
public partial class ClickatellCallBack : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)[code]....
Basically, this Page retrieves the Query String values sent from clickatell and inserts them into a database table.I have registered the following Callback URL:
http://www.mydomain.com/ClickatellCallBack.aspx with clickatell and selected the Callback Type: HTTP GET
In my 'sendmsg' command I set delivery acknowledgement and callback request as follows: deliv_ack=1 and callback=3
The only problem being that nothing appears to be happening. The CallBack URL doesn't appear to be reached by clickatell.Do I need to implement this Callback URL using something other than an ASP.NET Page? Is there some clickatell setting I'm missing?
Does anyone have a working example of returning jsonp data with callback in mvc 2 that they can share?
View 3 RepliesI'm trying to get a jsonp callback working using jquery within a greasemonkey script. Here's my jquery:
$.ajax({
[URL],
data: { authkey: "temphash" },
type: "get",
dataType: "json",
cache: false,
success: function(data) {
console.log(data);
}
});
in my webservice (asp.net) I'm returning the response with a content type of application/javascript. The response the server is actually sending back is: jsonp1276109314602({"message":"I'm getting tired of this not working"}) The jsonp1276109314602 method name is being randomly generated by jquery, and I'm grabbing it with Request.QueryString["callback"] However my success function is never called and the firebug console gives me an error saying jsonp1276109314602 is not defined. What am I doing wrong?
NOTE: I'm making this call from a greasemonkey script on a craigslist page. It's a cross-domain request, but I can see the request is actually making it to the server and returning a good response, but for whatever reason the registered callback that jquery creates appears to not exist when the response comes back. It works fine if I run the script in the firebug console from the craigslist page, but not when it's run from the greasemonkey script.
I'm using AJAX Page Methods, but I can't seem to be able to pass the needed parameters:
function getFavStatus() {
//favs is a list of DOM <imgs> that I want to modify their img.src attribute
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt,setFavImg(favs[i]));
}
}
function setFavImg(fav, response) {
fav.src = response;
}
The problem that I can't figure out is how to use the "response" from PageMethods, AND pass the DOM object to the callback function.
I've also tried doing something like this:
function getFavStatus() {
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt, function (response) {
favs[i].src = response;});
);
}
}
In this case, the response works properly, but i is always > favs.length, because it has already iterated through the loop... Edit: My PageMethods.isFavorite signature is: [System.Web.Services.WebMethod] public static string isFavorite ( string p_id )
Whenever a postback would occur (AJAX'ed by an UpdatePanel) I want to do a callback beforehand and only after the callback has completed (either successfully or not) should the postback occur. How can I do this?
Elaborate explanation: We use ASP.NET AJAX (UpdatePanel 'n stuff) together with DevExpress controls. Among those controls is the ubiquitous GridView. As is typical with ASP.NET gridviews, you can edit rows one-by-one, and to save your changes you have to hit the "update" button at the end of the row. However if you make some changes to the row, then forget to press the "update" button, and hit something else in the page (say the big red SAVE button that causes a postback and saves the whole form to the DB), your changes will be lost. The row will still be in edit mode, but it will have reset to the data it had initially when you started the edit.
Our clients are not happy with this and want the row to be saved automatically if the user forgets to do so himself. Luckily the DevExpress gridview is smart enough to have an "Update()" method which I can call from JavaScript. Unluckily that causes a callback and returns immediately. If I allow the postback to continue as normally, the callback will get aborted. Well, technically it's a race condition I guess, but so far it seems that the postback wins. There are events to which I could attach for success/failure of the callback, but I don't know how to "resume" the postback that started it all. We could turn off callbacks for all the grids, but that would be a performance disaster.
I try to use CustomValidator ClientValidationFunction. The issue I have is CallBack using Asynchronous call which make it difficult to detect when the call is complete.
var callbackresult;
function ValidateSomething(src, args)
{
MyCallBackMethod(param); How shall I check when the call back is complete??? Any workaround?
if(callbackresult == 'true')
args.IsValid = true;
else
args.IsValid = false;
}
function CallBackRef(result, context)
{
callbackresult = result;
}
