AJAX :: How To Use Server Controls With A JQuery Helper Page
Feb 4, 2010
I have build a server control that uses ajax postbacks in order to do db insert/update/delete.While redesigning our website, we are using JQuery for most postback. So we are using simple aspx pages that return only the html code we need to display. However when I am using this control, Ajax functionality does not work.First of all, I need to put a FORM element which later is removed since the behaviour of JQuery with two forms is strange.Second, I am receiving an error that __VIEWSTATE is invalid. Tried to remove it with no luck.How am I going to use this control with full functionality in a page which is used by JQuery to return results?
I wanted to write a code for JQgrid in asp.net .I have tried the same in asp.net MVC,but i want it now in asp.net .n MVC we use Helper class,and return json data,so what to do in asp.net where helper class can not be used.Serialization can be done with data to get it in json.,but what about Htmlhelper.
Is there a way to pass a reference of a page to a helper class? Scenario: [ASP.NET 2.0 Web Application] The page is a content page which has a MasterPage. The page calls a method in the helper class and passes the page byRef as an argument. The method in the helper class tries to find a control on the passed in page and set values. Problem: Only the MasterPage is being exposed and not the page I am trying to pass. Any recommendations on passing the page so that I can set the values of the controls within it?
I'm sure I'm going about this wrong but I'm trying to write a simple javascript method that will set a hidden type value upon a link click. I'm using the Html.BeginForm() helper that contains two links similar to:
@Html.ActionLink("Delete Review Only", "Delete", new { id = Model.ReviewId }, new { onclick = "SetDeleteType(1);" })
The supportform name obviously doesn't exists since I'm using BeginForm() and can't specify a form name. Is there a clever way of doing this without calling Forms(0) using jQuery or something or am I completely off?
I'm trying to save some content whenever a button/hyperlink is clicked using jquery.ajax (Using Asp.net 3.5). The logic is as follows:
Through .bind in jquery I bind my own method(MakeLog) to a button click or hyperlink click. The click events of button/hyperlink contain nothing, I need to use .bind for selective controls.Now we have a button whose click event will fire a method, say MakeLog.Code snippet for MakeLog is as follows:
This works fine in IE but in Firefox this is not sending the data back as expected.I tried to identify the issue and came across the following: http://stackoverflow.com/questions/3522944/jquery-ajax-calls-async-false-vs-async-true .What I understand is that, whenver page is redirecting/reloading due to button click or hyperlink click the async call is not working properly.
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
I need to make an ajax call from my javascript and access a control on my page. Using a webmethod wont work then since it's static, do I have any other options?
When is it appropriate to create a helper class for a sql server database using the asp.net framework? Basically I'm trying to create a minature wiki (with multiple pages) and storing all of the data/strings for a specific page into a table on it's own.
Can I call Ajax.BeginFrom from a custom helper method ?
AjaxHelper is not available in a custom helper method, so I tried to pass the "Ajax" available in ViewPage to Helper method while calling it, but then in method, BeginForm is not available on that passed "Ajax" parameter.
I have just added routing in a new asp.net 4 web forms application, and have got my route table set up ok and page requests are working fine. What I now want to do is use the Page.GetRouteUrl method whenever I need to generate one of my seo friendly Url's. I started to implement this across various pages then thought it might cut down on code a bit if I had a method in one of my own helper classes, that constructs this url (using the Page.GetRouteUrl method) as I might have several parameters that need to be specified against the Page.GetRouteUrl method each time.
However, within my helper class, it doesn't know what 'Page' is. I was thinking I could pass in 'Page' from the page that wants a routed url to be generated, but in some cases I want to construct one of these Url's in another class which doesn't know what 'Page' is, and in that scenario wouldn't be able to pass it in as a param (and therefore wouldn't be able to use the Page.GetRouteUrl within my helper class). What is the normal approach when wanting to use Page.GetRouteUrl within classes that don't have an instance of the Page object?
and I am calling the webmethod by javascript like this [Code]....
The result is, I get the error function running and I get "undefined error" alert.Am I calling the procedure correctly? I put a breakpoint on the webmethod and it.
1- I have an Ajax link that call an action and that action returns a view , that view open in a specific Div (consider it as a menu that update the div with the corresponding view) 2- if session timeout the returned my logon view so if i click on the link and session is timeout , the log on view open in the div not in the whole page
what i should do so if the session timeout it return logon view in new page in on my div?
How do I go about making true ajax requests to an asp.net page? (Not update panels). I read this tutorial but couldn't get it working. Is there a better approach? Or should this work?
I would to know how can it be achieved by loading page content into a specific DIV without entirely refreshing a page. I mean if I click on linkbutton or a normal link on my menu bar like Contact us, the conact us content is loaded into the DIV and the same if another link is clicked on the menu Bar.
I am using C# ASP .NET MVC and ajax calls. I am able to get the display of the table along with all features. But, I don't understand how do I add a checkbox and button. I have tried dom-checkbox as well but can't get it to work.
I have asp.net label called NumberLabel.It is changed from codebehind(asp.net/c#) by calculating the number of rows in an sql server table called "MyTable". Every time a user open this page,the same code/stored procedure is executed to bring the number. Is there a way to to bring the same number for all users and change it only when there is an update in "MyTable".this will optimize a lot time,executions,(SQL server side and webserver side).Does asynchrounous c# exist?or doing that by ajax.
How can you perform page navigation with Jquery tabs without the ajax events firing? Following the tutorial, I added
$("#tabs").tabs({ select: function (event, ui) { var url = $.data(ui.tab, 'load.tabs'); if (url) { location.href = url; return false; } return true; } });
And I added hrefs to the tabs going to other pages. The problem is, I have ajax used on the page and onload it posts to the url with an ajax call. I was hoping to disable ajax altogether for the tabs and just use them for straight navigation so I can leverage the styles.
