MVC :: Jquery Ajax Post Data Not Visible?
Mar 28, 2010
I haven't used Jquery to post Json data to mvc before, so this maybe a Noob issue.
I've got a really simple form, and am trying to post this data async to an mvc action. Within firefox I can see the data being posted, but I can't see it within the MVC action.
This code all runs through correctly, but putting a debug point in the action method will always show the form collection as empty.
Form..
<script type="text/javascript">

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).

The usee then fills out the rest of the form and then saves the document.With the image extraction, I was owndering if it was possible to do that as an ajax post. The other submit button can work as a normal http post

I need to pass a customer id to get some data back for a customer from a webservice. I can't figure out how to get to the webservice, I have a breakpoint set in the webmethod but it's not being hit and the alert box is not popping up either. For a test I am just trying to show some value from the returned data in an alert box. Note I am just hard coding the customer id of 1001. The webmethod takes a parameter of string customerid.

Does some one know what's missing or how to debug this issue?

Also, how does that change the deserialization of my data? Will I still be able to use code similar to below:

I have a WCF web service and jQuery AJAX implementation that appears to be working perfectly, save for a single line of code: the AJAX calls to the WCF service only have the correct HTTP header & content information if I use GET in my AJAX calls. Once I choose to use POST, the WCF service response with "Method Not Allowed". The calls are coming from domains such as sub1.domain.com, and calling svc.domain.com. How can I configure WCF to allow the cross domain AJAX POSTs?

How can I upload files asynchronously with JQuery?
I have a file upload field, after the image was selected, i make a jquery ajax post to an aspx page's page method. My question is, how can I pass that image via jquery? When I do $(this).val() it only gets the file name. I want to pass the image object itself.

I have an ASP.NET MVC controller action with the following VB.NET signature:
<HttpPost()>
Public Function ClosestCities
(ByVal position As MapCoordinate, ByVal citiesCount As UInteger) As JsonResult
The MapCordinate class is:
Public Class MapCoordinate
Public Latitude As Double
Public Longitude As Double
End Class
If I'm trying to send an Ajax POST in jQuery to the ClosestCities action, what should my request look like?
When I use the following code to POST to this action, in the debugger window of VS, position.longitiude and position.latitude are equal to 0.0 (0D):

i have a website where i provicde a link. On clicking the link a controller action method is called to generate a zip file after creation of zip file is done, i show the link to download the zip file by replacing the link to create a zip with the link to download the zip.
the problem is that after zip file creation is over and link is shown, when user clicks on the link to download the zip file, they are sent to login. After providing correct credentials in the login page they are prompted to download the zip file. they sould not be sent to the login page. In the action to generate zip file i haven't abondoned the session or haven't not done anything that abondons the session.
the user should not be sen't to login page after successful creation of zip file user should be able to download the file without login. i search internet on this problem, but i did not find any solution. In one of the blog written by hanselman i found this statement that creates the problem with the session: Is some other thing like an Ajax call or IE's Content Advisor simultaneously hitting the default page or login page and causing a race condition that calls Session.Abandon? (It's happened before!)
so i thought there might be some problem with ajax call that causes the session to expire, but i don't know what is happening? it's like this after users click on the link to create zip file the zip file is created successfully but the session gets expired. this is not what i want. Why does the session has to get expired after making a jquery post call to controller action to create a zip file? i hope u understand the problem.

I have a web page that I have a media control player on along with other controls in a table.It's a training video, so the controls are not visible.So the user can advance to the next web page,I thought I would have a button control inside an update panel with a time control so that the user had to watch the video and then the button control would appear after the video completed.I'm setting the button update panel to NOT visible and then turning it one when the time control elapses the same amount of time that the video runs.My problem is that when I set the visible property of the update panel to NOT visible it also makes the media player's panel NOT visible too.They are in two different panels.The medial player in a standard panel and the timer control connected witha separate panel that contains the button for the user to proceed. When I set the visible property to "true" the media player runs but the update panel with the button is visible also.
[Code]....
This is the code for the update panel and continue button that is in a separate table cell.I even split the table and so this is in a completely separate table but I still get the same behavior.
