I am new to Jquery and trying to start learning the new tool. What I want to do is call a JQuery message box from my gridViews Row Command function after the processing is done so I can notify the user the process has been complete. I was trying to use this website as a referanceBut not sure how to call the function from the serverside. I have triedPlace this inside your script tags...
$(document).ready(function () {
//Determining if there is a message to be shown if the message is not equal to empty string then the messagebox should appear.

i have a jQuery AJAX webmethod in ASP.Net that works perfectly fine when tested locally. but when uploaded to the server, sometimes it works sometimes it doesnt. when i debugged the code with firebug i see the the webmethod gets called but jumps right away to the error section of the ajax script.
jQuery code:
<script type="text/javascript">
$(document).ready(function () {
//get current date

I'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult
Dim result As New WebReturnObject
Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.
i am using this Page.ClientScript.RegisterStartupScript() to call a javascript function from vb code behind , and this works fine with me My question is how can i send variables from the code behind to the javascript function here is what i have tried so far :

In short I want a call a function jAlert() from jquery.alert.js file in a .aspx.vb page.. More details below
"When I click on "update page" the control goes to "ActionRepeaterItemBound" on code behind and then to my action.js page and this way I am able to add attributes and use them while calling my jscript function. However when I click on "Submit Update", the control first goes to action.js and then to "ProcessAction" on code behind. So I am not sure how I need to add attributes before the control goes into action.js."
I have a file jquery.alert.js which have functions like jAlert().
I have a file .aspx with part of code as below
[Code].....
My aspx.vb page has a function as below where attributes are added to control and are used in a page action.js to call the jAlert function
Protected Sub ActionRepeaterItemBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs)
I want a similar logic to be performed on my LinkButton "CurrentActionCommit". How can I do this?

I am trying to use PageMethods to call a function from the server side, but I am getting an error that PageMethods is undefined.
Here is what I have put into the html
<asp:ScriptManager ID="ScriptManager1" runat="server"
EnablePageMethods="True">
and here is the function from the code behind.
<System.Web.Services.WebMethod()> _
Public Function LoadChild(ByVal EntityID, ByVal EntityCat, ByVal lnType, ByVal FullExpand, ByVal lnEquip, ByVal lnTemplate) As String
and here is the call to the function using page methods.
PageMethods.LoadChild(lnEntityID, lnEntityCat, GLOBALEQUIPID, FullExpand, 0);
can anyone see why I would keep getting a PageMethods undefined error?
edit - part of the issue may be because the function isnt shared, but when shared is put in, i get this error in about 15 places. - this is refering to the session I am using - here is a snippet of the session being used that is showing an error.
prm4.Value = Session.Item("user_id")
I am getting the word session underlined with the error message below - any suggestions on how to fix this? this could fix the whole issue all together.
Error 305 Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.

I don't know why calling another function inside the OnUploadedComplete does not work in ordinary way, It's my code:
ASP.NET code:
<asp:AsyncFileUpload ID="AsyncFileUpload1" runat="server"
OnUploadedComplete ="UploadFile1"
OnClientUploadComplete="uploadComplete" ThrobberID="myThrobber"
onclientuploaderror="uploadError" CompleteBackColor="White" />
VB.NET code:
Protected Sub UploadFile1(ByVal sender As Object, ByVal e As System.EventArgs)
'saveing file on disk, this part works fine, but calling
'myfunction() does not work properly

I am struckup with a problem from last two days. I am creating a web application using VB.NET, Ajax & RAD Controls. When user clicks on a button I want to open a RAD Window and show the list of ledgers available to the user, so that he can select one from the list. And to open that window I have to call a java script function from client side, which is already achieved using the below code.

Can I send an object from client-side javascript to server-side code via ASP.NET ?
View 5 RepliesI know this defeats the purpose of client side vs. server side (refer to title of this thread). What I would love to do is build my own custom progress indicator on the client showing how far a server side code has progressed. I figure if I could only get a JavaScript to fire and render a value of some control at pre-defined intervals while the server is working I could make it happen - but alas I'm beginning to believe that this is impossible. Below is some code that performs three 2 sec loops. At the end of each I want to change the visible value of a control on the browser. [Code]

I need to send back the id, the old value from _1 and the new value from _0 back to the server. What is the best way to format this data so I can easily extract the data from the server side so I can easily email someone for example to let them know which textboxes have changed, what the old values were, and what the new values are
At the serverside level, I am using .NET-3.5 (VB). I know how to send the data bacl. and how to email the data, I just wanted to know how to best format the data at clientside before sending it back. I could have upto 50 sets of id, old, and new values to send back. Sorry for not making that clear earlier.

I add an option to a select with jQuery. When I save with an asp button, I don't see the changes on the server side in the click event.
And the HTML is all correct after I add the option.
Is it a coding problem or I don't understand something?
$(selectCourant)
.append($("<option></option>")
.attr("value",$(dropdown).val())
.text($(dropdown + " option:selected").text()));
I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.
View 14 RepliesUltimately, what I want to accomplish is an AJAX-based messaging system. I already have a database table for messages, and an ASPX to add new messages (and declare old messages no longer relevant).
The current messaging system simply polls the server every 15 seconds, and re-pulls the current message set.
What I am looking to do is: On $(document).ready(), register an ajax callback function that listens for a server-side event (e.g., MessagesUpdated) On table insert/update, fire MessagesUpdated server-side.
This way, whenever the table is updated (or new records added), any clients listening know that new data is available and can re-poll the server then.
Ideally, I'd also like to make the new data available as an event argument (to minimize re-polling the db).
I can find references to something like this in other languages, but I cannot find any actual code examples to get me started.
Assuming this is possible to do via .Net, can anyone help get me started on this?
I'm using the 2.0 Framework. Also while I added a VB.Net tag, I can read C# reasonably well, so please feel free to post in either language.

Be able to instantiate the object and hook up the MessageReceived and ConnectionChanged events (or ones with similar purposes). Be able to send data (duh) When data is received, it fires the MessageReceived event on the same thread that the object was created on (this would be nice, but not absolutely required). Have a blocking and non-blocking options for connecting and possibly sending data.
View 2 RepliesI'm curious about how to perform client-side filtering, where Javascript is involved (it may not need to be written, but his is what the user's browser will run). It shouldn't need ajax (though ajax related solutions are welcome).
I'm brand-new to Asp.NET programming. This example pertains to a problem I am having at work. I've done many years of application based programming, and even some php. But learning Asp.NET is giving me a hard time (something I wasn't expecting).I have three combo boxes. But I want to filter out what gets put into them based on what is selected and what is available (an extra table).
Here is the example code page. Right now there is only a blank Page.Load() in the code-behind .vb file.
[Code]...
p.s. I work in the morning, so I will be around again in about 12 hours. Off to sleep with another day of no solution. Example Project is where the initial code is from.
i have a question ( i am learning VB) is there is a way in vb.net to make the Me.LoadComplete loads after the client side , i develop this simple code to make it easy to understand my question
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.LoadComplete
MsgBox(myhiddenField.Value)
End Sub
[Code]...
when the page loads , the MsgBox will be empty but when you click the link button the MsgBox has the value you set in the javascript , so i assume that the page_load function gets excuted first
the question is how can i load the client content before the page_load ?
I'm having a http handler that is retrieving images from the file system on the server. I need to cache these images on the client side(browser). For that thing i'm doing the following code

The thing happening with this is ... When i switch between the tabs its taking it from the cache... but when i hit the browsers refresh button its again going to the file system on the server. how to cache these images on the client side.
P.S: Cant do markup caching for all the pages im my application.

View 2 RepliesI have a client-side app which I am working on. As I start to enhance the app, I am starting to wonder whether or not I should be building a network side app instead. My app in its current form sits on the client side and generates some text and XML files which are stored locally on the client side. The user reads/write to these files. However, I want to start working with SQL AND the processing time of my app is starting to consume resources (i.e. time and CPU) on the client side.
Can someone provide me with some highl level feedback on what one would do to make their client-side app a network app that multiple users would have access to. I realize more detail would need to be provided in order to provide thorough answer. However at this point, I really just want to understand how a network app would differ from a client app from a programminga and deployment perspective.This is not necessarily a VB question. Howevever since I am working in VB I though I would start in this forum. Feel free to move to the appropriate forum if need be.

View 2 RepliesCurrently, in my web application I have a listbox that gets populated client side (via java script) with a set of ids -- we'll call this page 1. Server side, I am populating a variable with the ids and passing it through a query string to another page -- we'll call it page 2. Now, I have a previous button on page2 which allows me to go to page 1. I'm trying to figure out how to repopulate the listbox on page 1 with the values previously selected. I was thinking of just storing the set of ids in a session variable and using it client side to repopulate the list box. Can anyone advise on how to access a session variable client side?[code]...
