I have a form with three filed name city and relation.relation filed is a dropdown and on the selection of relation i have to display list of users in grid.I want here to use Ajax or Jquery so that when i select relation not whole page will post to server but only relation and could display list of users in grid.
inside Html Table i have all these fileds( Name,City and Relation).
Basic concept of AJAX is to cause Partial post back of the Page. If we use AJAX, Page Load occurs, than what is the difference between normal Pages' Page_Load event (without ajax) and Page load event of a Page with ajax.
View 10 RepliesI have multiple update panels in a page. how I can know which update panel caused partial page updation on client side before page is partially updated?
View 3 Repliesim using a init function after partial postback again the init function is not calling.
<asp:ScriptManager runat="server" ID="MainSM" EnablePartialRendering="true">
<Scripts>
<asp:ScriptReference Path="~/JS/menu.js" />
</Scripts>
</asp:ScriptManager>
<script type="text/javascript">
menu.init("class");
</script>
this script works fine but after partial postback again this init function is not working. So i searched in google i found some articles regarding this [URL]
<script type="text/javascript">
function pageLoad() {
// Initialization code here, meant to run once.
</script>
this works fine when it was postback,but without postback this init function is not working
watch here:
- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.

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.

I was just wondering if its possible to do an ajax post a file in asp.net mvc,basically i have a form with two buttons, one of the buttons extracts images for the selected document and displays them for the user to choose thumbnails for the document he is about to upload. 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
View 5 RepliesI 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.

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?

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 used update panel and in that update panel I have kept ASP Table control in which I am creating rows dynamically which in turn contains 1 dropdown lists and 3 text boxes. My problem is that after partial postback text boxes and dropdown list are found but text property of text boxes is showing empty and dropdown list's selected value is set to the first record in that box. I have also stored entire table in session and retrieve it in(!isPostBack) condition at page_load event.

I want to add one row on every addRowTbn click event there by retaining previous rows.
I have recently started learning ASP.NET with MVC 2 Framework, I am facing difficulties in the following scenarios.In my MVC application I want to retain partial information in Model over post backs.Following is my scenario,
1. I initiate "Edit" of main record by clicking date hyperlink from left navigation.
2. Amend some data.
3. Save the record.
4. "Edit" sub record of the saved record by clicking another hyperlink from bottom left navigation panel.
The page is divided in to 6 tabs, the first 5 tabs shows the data for the main record and the 6th tab shows data of sub record. Wehn we "Edit@ sub record the previous 5 tabs doesn't have any changes noted, that means there is no harm in keeping their details intact in the main model. So is there a way to access model in the controller on hyper link click action so that I can only load the data for the clicked sub record (I am asking this, because the hyperlink click uses HTTP GET method so no model parameter passed in action method). If no, then how do I retain partial values in the Model over post backs?
Note that each tab data have been kept in individual models, and a main model has a collection member to hold all these individual models together.I thought as the model is binded with the view, it is too binded with controller. But it is allowing easily to access model in variable "Model" for the view but not for the controller.
