I'm using Ext Ajax TextField, I need to call a script with 3 parameters.this script actually worked out fine for my ASP TextBox control.I tried the following ways i dont know where i'm naking mistake.
Script On the .aspx page:
<script language="javascript" type="text/javascript">

[code]...
how to use listerner? to call a javascript or Solution to restrict to disable pasting strings into NumberField.How to pass the event, client id and the validator(to be disabled Onchange)
Iīm using jQuery to make the ajax calls to web services. Iīm not using json, I want the information in XML. If I donīt pass parameters and I make the WS parameter less it works but if I want to pass a value as parameter (I tried int and string) it doesnīt work. Here is my code:
jQuery: [Code]....
The web service
[Code]....
The error that I get from firebug is an exception System.InvalidOperationException and it says that the parameter region_id is missing.It canīt be very difficult because it works without parameters but all the information I find in internet
Everything works fine when manually done. As an option is selected, the onchange code is called.
The problem begins when I try to change the selected value using a piece of Javscript. I want to be able to automatically change the selected option using JS, whilst still having the onchange code called, exactly as if done manually.
I try calling this:
form.SList.value = "33";
The right option is selected, but the onchange code does not get called. So then I try doing this:
i want to update my page from database every 20 Sec..so for that i want to pass multiple data fields from server to Client using AJAX.. what can i use for that except using xml?
I am having fileupload control having its "multiple" attribute equals to "multiple". I am facing a weird issue in CHROME browser. The isse is that onchange event of file upload control is not firing for more than 12 files selected at once. The event is firing if I have 10 files selected at once. On FF and Safari it is working fine. Here is the code:
After upgrading our project to the .net 4.0 framework (from 3.5), we facing some problems with ajax calls with html in the parameters. As soon as the user enters some html in a text area the ajax call isn't executed anymore. If the user enters plain text only, there is no problem.
I have a page with an AJAX TabContainer and 4 AJAX TabPanels and have Save button. On a button click im calling javascript thats make ajax tab disappear why?
I have an updatepanel on the webpage and also the event UpdatePanel1_Load. After the webpage is loaded I will have the possibility to call the javascript function: "CallUpdatePanelLoad()" My question is how it would be possible to exectute the UpdatePanel1_Load in C# from this javascript function?
Having a ModalPopupExtender, the idea is to run a delete process from a SqlDataSource when Cancel button is clicked.
Our approach is as showed below:
<script type="text/javascript"> function deleteRec() { alert("Call a Protected Sub btnNo_Click!"); } </script> <asp:ModalPopupExtender ID="Panel1_ModalPopupExtender" runat="server" PopupControlID="Panel1" DynamicServicePath="" Enabled="True" TargetControlID="btnFirePopup" BackgroundCssClass="modalBackground" Drag="true" DropShadow="true" OkControlID="btnYes" CancelControlID="btnNo" OnCancelScript="deleteRec()" > </asp:ModalPopupExtender> Protected Sub btnNo_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnNo.Click TempDB.Delete() End Sub
First question: It's that correct?
Second Question: Is so, how do we call a Protected Sub from JavaScript?
I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is [URL]). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Some of the changes I made was adding the following to the Operation Contract:
I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc.... I am willing to make any changes.
i have a jquery .click() function that executes an .ajax() method call
[Code]....
when the .ajax() method executes succesfully it calls a javascript function
[Code]....
as you can see i have an .ajax() method inside my javascript function, is this possible? I am creating loop that starts on the finish listener of the soundmanager object. So when I need to make the ajax call to get he next url I need.
I know that I do not want to actually use an Ajax.ActionLink from within a JavaScript function, but for the life of me I cannot figure out how to replicate the behavior. Here is what I have in my MVC 3 RC2 _Layout.cshtml:
[Code]....
I do NOT want to use:
[Code]....
Unless that can be made to populate at runtime, on demand from a script. manually clicking the ""Load Menu" ActionLink works exactly like I want except it requires the user to click the link; I want to do that for them... in this case from the Body onload event.
I have ASP.NET form where i have Implemented Ajax ValidatorCalloutExtender for Validation Purpose. So can i call a JavaScript Function from Ajax ValidatorCalloutExtender for checking Correct Data entered by the User.

I'm calling a webservice using jQuery with .ajaxHere are the data parameters for the call:
var parameters = "{'Titre':'" + Titre + "','Description':'" + Description + "','Contact':'" + Contact + "','VilleId':'" + VilleId + "','QuartierId':'" + QuartierId + "','UserId':'" + UserId + "'}"; It works fine. But when parameters Description or Titre contain the ' character , no call!!!

I'm having some trouble with making use of some AJAX-properties that are normally accessable after I've initialized a scriptmanager.

[Code]....
Now, I would like to call the javascript-function 'testFunc()' from my ASP.NET Codebehind-file, and here's my problem. I keep getting "Sys is unidentified".codebehind-stuff: ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "testkey", "testFunc();", true);
Does anyone have good idea how to solve this? Much appreciated. Thanks.
FOr this i Used __doPostBack but page flickering is occured eventhought if we keep update panels,
I have a gridview control from gridview I am calling RowCommand event and then a Popup Page from Popup i will return some values and again i need to bind the values back to the DataTable and then to GridView.
In JS if i User doPostBack('xyz','') page flickering is ocurred and if i user doPostBack('updatepanel1','') ID also flickering is not occuring bt values gets binded to GRidview after 5 sec delay....
is ther any alternate sol for this to do...
any Jquery or any JS???
or if i use ScriptManager Page Method is there any issues with that bcz we need to have a static method in server side.....:(
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.
I have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured
"WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON."
Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example:
function OnRequestComplete(result, userContext, methodName) { var Person = eval('(' + result + ')'); alert(Person.Forename); alert(Person.Surname); }
So is the first technique is correct? or what?
P.S:
the function on the server is defined on the default.aspx.cs file as follows:
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()] public static string[] Foo(string s);
from the client side the calling is as follows
PageMethods.Foo("value",OnSuccess);
Also all the users have the same browser version (IE8)
I have a ReorderList from the Ajax Control Toolkit on an aspx page. What I want to do is to enable a button after the order of the items have been changed. I already have the javascript function in my page in a script block, but how can I tell the ReorderList to call the javascript after order has been changed?
condition : server = asp.net FW3.5 .... Client = just and just htmls (no server control /no runat ="server" att)
i open a ajax request from browser and that is ok problem:
1. in case above a page_load happend on server we all know that, but i cant determine is it asynchorus load or normal load 2. as response of that AJAX call i can't use response.write() cause it will redraw entire page not just a portion
In Litle Details: suppose i there is a <div id = ....> on client page, i just need to send a table, after that javascript will put that under the div. and response write can't do this cause it send xml for entire page not for just tha table.

I am developed an web application in asp.net. In this application I have used jquery ajax for some pages. In this application, when I make two ajax call asynchrounoulsy that would not do as I expceted. what is happening is even the second ajax call finishes i can see the result when the maximum time out ajax call finished. I mean i can see the both results in the same time, not one by one. for an example. I have 3 pages
1) main.aspx - for make two ajax request.
2) totalCount.aspx - to find the total count. (max it takes 7 seconds to return, as corresponding table contains 3 lak records)
3) rowCount.aspx - to find the row details. (max it takes 5 seconds to return result).
due to this scene, I have planed to make asyn call in jquery ajax in asp.net. here is my code...
function getResult() { getTotalCount(); getRows(); } // it takes max 7 seconds to complete // as it take 7 seconds it should display second.( I mean after the rows dispaying) // but displaying both at the same time after the max time consuming ajax call completed. function getTotalCount() { $.ajax({ type : "POST", async : true, url : "totalCount.aspx?data1=" + document.getElementById("data").value, success : function(responseText) { $("#totalCount").attr("value", responseText); } }) } // it takes max 5 seconds to complete. // after finished, this should display first.( i mean before total count displays) // but displaying both at the same time after the max time consuming ajax call completed. function getRows() { $.ajax({ type : "POST", url : "getrows.aspx?data1=" + document.getElementById("data").value, async : true, success : function(responseText) { $("#getRows").attr("value", responseText); } }); }
I would like to know, If there is any possible to make asyn call in jquery ajax in asp.net. I searched in net, I got some points that says we cannot do this in asp.net ref link: [URL] if we can do this in asp.net How to do that?
