My web app is using a sliderextender to allow the user to change the distance. After the slider handle is moved and the mouse button is release, I would like to call a function to query the results and rebind my datalist.
How can this be done?
my slider control is:

Is there anyway I can handle both json and html return types when posting jquery ajax:
For example, this ajax call expects html
[code]....
I've created a C# function which extracts data from an mssql database, formats it to a json string and returns that. Now I need to make a call from my javascript (jQuery) slider through an aspx page that is related to the C# code file. I have actually never done anything like this before, from what I could tell by googling I need to use xmlHttpRequest, but how exactly do I make the function get hold of this string? It would be awesome if someone had some example code that shows how this works.
View 2 Repliesi 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.
View 1 RepliesI have a controller:
<asp:Button OnClick="MyFunction" runat="server" />
I want to be able to call MyFunction without the page reloading. Is this possible with ajax or something?
If so how would I do it?
<asp:Button id="Bu_DocShareSave" runat="server" Text="Save Share" OnClick="Bu_DocShareSave_Click"/>
protected void Bu_DocShareSave_Click (object sender, System.EventArgs e){

I'm having some trouble with making use of some AJAX-properties that are normally accessable after I've initialized a scriptmanager.
ie. This work:
[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.
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)
Let's say I have a Label on my page. In PageLoad() it's Text parameter is set to "This is my first text".
After, for example, 1 minute I want this Label to change it's text parameter to "This is my second text" (completely automatically, without any interaction of a user with this site).
What is wrong with this code? I am trying to pass parameters to a WCF function. I couldn't get this to work. I am getting Ajax error.
$.ajax({
url: applicationPath + "/Test.svc/GetData",
type: "POST",
dataType: "json",
data: '{GId":' + sender.get_value() + '"GName":' + sender.get_text() + '"mId":' + testId + '}',
contentType: "application/json; charset=utf-8",
success: function(result)
{
//trying to fill combobox here
},
});
What I want to do: dispose of a session upon detecting an "OnBeforeUnload" event in the client. I know it doesn't fire 100% of times (90% accuracy works fine for me)
Here I saw how to do it with ajax, this system, however, breaks down with ajax: I can't use it at all.
I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.
Once i push the button to execute the JS/AJAX/codebehind - I got an error.
POST http://************/admin/Admin.aspx/getDBInformation 500 (Internal Server Error)
This is my code below that I am currently using:
Code:
<WebMethod> _
Public Shared Function getDBInformation() As String
loadDBData()
Return JsonConvert.SerializeObject(dbInfo, System.Xml.Formatting.Indented)
End Function
End Class
The code behind looks like this:
Code:
Imports System.DirectoryServices
Imports System.Security.Principal
Imports System.Net
Imports System.Drawing
Imports System.IO
Imports System.Data.SqlClient
Imports System.Web.Services
Imports Newtonsoft.Json
[Code] ......
How can I correct this issue so that I am able to call **loadDBData()** without that 500 error?
I am getting a JSON object from a webMethod by the call below and I set some textBox values based on the returned objects attributes.Problem is, just for a moment my textBoxes are populated but then immidiately they return back to empty.Do I make a mistake or I cannot make DOM elements modifications within a success function?
var ajaxCallOptions = {
type: "POST",
contentType: "application/json; charset=utf-8",
url: "/JQuery/Chapter16-AJAX/PersonWebServices.asmx/GetPerson",
personId'));"/>

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();
[Code] .....
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" >

i got a javascript function that i want to call on <aspImabutton onclient event but it keep saying function not defined.
[Code]....
I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript functionIn order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there.
Protected Overrides Sub AddAttributesToRender(ByVal writer As HtmlTextWriter)
MyBase.AddAttributesToRender(writer)
If MyBase.RenderUplevel Then
Dim clientID As String = Me.ClientID

Requirement: An AJAX slider control have two sliders on a single bar. So that max and min can be selected.
Reference: http://www.google.com/finance/stockscreener#c0=MarketCap&c1=PE&c2=DividendYield&c3=Price52WeekPercChange®ion=us§or=AllSectors&sort=&sortOrder=
- see the company distribution slider. Here there are two bars and moving it changes the bided control value as well.
I have a slider that is getting its initial value from a data table. I am trying to update the value upon textxhanged event. My means of accesing the data table is linq. The intitial value is correct and the update event works but the updated value is whatever the default for the textbox is. How do I get the value of the slider extender itself? Here is all related code:
[Code]....
As you can see I put in a value of 20 in the label.text and that is what gets updated to the db. if I leave both the textbox.text and the label.text empty the db gets update to an empty field. I have seen mention of a value attribute for the extender but have been unable to figure out how to use it.
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I realized I incorrectly posted my code when I originally posted this query so I will try again. I am trying to use a Slider Extender with the values 1.00 to 7.00. The Slider works properly but I would like to add labels to the slider with the values 1 thru 7.
