I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX

I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?
I want to do something a little bit tricky here. I want to call a server side fonction from the javascript. I know it can be done but I get some errors. This is my Javascript fonction where I want to call the server side fonction:

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
Im using some animationExtenders in my project. The thing is, the objects to be animated are created programmatically, hence i need to also build programmatically the javascript code that will interact with them.
It runs properly but, when i interact with these animated controls and the javascript functions are supposed to get to work, i keep getting the usual run-time error saying that the javascript functions are not defined. But, if i check the final html code generated, i can see how all the controls i built programmatically are there ,as well as the script.
Tried both RegisterStartupScript and RegisterClientScriptBlock, no luck.
I have MaskedEditValidator, which set u pt ovalidate datetime entry into text box. After that the button (html button input control )is pressed in order to start some process. Button is running the client side function (JavaScript).
Now in case of wrong input validator shows proper message, but how I can prevent button to be pressed and start the process. I.e. is it possible to check on client side the status of the validation?
I read some articles in MSDN magazine about new features in ASP.NET AJAX 4.0 - primarily client side data binding. I feel MSDN magazine sometimes contains a lot of "marketing" so I'm interested in opinions of real developers. Does it worth it? Do you plan to use it? Edit:Here are links for articles if anybody is interested. But at the moment it looks like dying framework for enthusiasts only.Data binding in ASP.NET AJAX 4.0Conditional rendering in ASP.NET AJAX 4.0Live databinding in ASP.NET AJAX 4.0Master-detail view with ASP.NET AJAX Library
View 2 RepliesI am developing a web application that needs to retrieve, display and write data to an SQL database. I'm trying to use AJAX and Javascripts in order to populate fields, lists and data, and to have button and calendar controls on the page that can update the page without refreshing and losing the data page. Therefore, it's necessary that I find ways to doing as much as possible client-side, without page refreshes.
Now, for security purposes, I've heard that there's a method for retrieving a copy of all relevant data from SQL at loading time, keeping a copy of it, perhaps on a separate page, and send-retrieve-display this data on my page, and then, at Submission time, write this data back to the Server. This is to minimize hits to the Server and to preserve data integrity. I've heard that doing this is called using an Extender, but we can't find examples of how this works so far.
is there any way to check whether the DB connection is exist or not from aspx client side?
View 6 RepliesI have a page where i have the products names and their prices displayed using a repeater control. The sum of prices appears in the footer using a label. Each detail row has a checkbox, which can be checked unchecked to see the total sum of prices.
I have already done this using javascript.
My question is ,
"is there any better way like using any AJAX control to do this ? or this is the only way to do it without posting back to the server?"
I have been struggling with this issue for a couple of days now.

Client-side filtering. Begin typing an Item name in the filter box above the "Item" column (Grid View) a live filtering will take a place to filter the input letter till the user find what he/she is lookin for.

I'm want to build web site in asp.net(because I know this language) in server side, and js (probably jquery) in client side, with Ajax technology. I heard that ASP.NET AJAX is too slow, if it's true (is it?) - what are the other options (to combine ASP.NET and Ajax) for me? Which tool combine all that technologies?

I know how to do it via RowDataBound as follows: Is there a way to wire it up in ClientValidationFunction property?

for the past 6 hours i have been going trough a million forum posts , I've been reading blogs , tutorials documentation and more.
Unfortunately, the amount of deprecated information is absolutely overwhelming.
All i'm trying to achieve is to change the value of a parent dropdown to something else, programmatically, and then have the child dropdowns to refresh.
By now I'm quite certain i have to use the function _onParentChange in some way.
Whit this function i can actually get the first parent to refresh, how ever the functions seems to be doing absolutely nothing when i call it on the child
