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'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.
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]
View 8 RepliesI 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:

OnClientUploadComplete="uploadComplete" ThrobberID="myThrobber"

View 7 RepliesI've got a asp.net gridview and inside of the grid view I have a check box at the header of the grid view like so: [Code] This gives me a nice little check box at the top of the grid view, the event OnCheckedChanged calls a function called SelectAllRows that looks like this: [Code] So if I click this header checkbox it checks all of the items in the gridview, and if I uncheck it, it unchecks all the items in the gridview. This works fine...but what doesn't seem to work is if the page loads up and I check the grid view header checkbox to true and it selects all the items in the gridview, then i click a button such as a DELETE button that calls some server side code. That code simply loops through the grid view and checks if the checkbox has been checked, if it is it calls code to delete an item.

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()));
Ultimately, 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 have an ASP program that synchronizes 2 databases. I also have a VB.NET program compiled down to an EXE that fills the source database before the synch happens. In the back of my mind I know I should be able to link the VB & ASP .NET programs together since that's the power of .NET. Alternatively, if I could run the EXE from ASP it would be just as well for my project. I do have the source to both programs. The ASP script was written with a text editor - the VB was in VB 2008 Express.
assume I know nothing of linking assemblies and such because I don't - I just read that in an article. I'd prefer ASP but if necessary I could use the ASP.NET script to launch the EXE. The code is legacy ASP with VBScript so all our ASP.NET stuff is the VB flavor as well. C# makes my other programmer's head hurt so for his sake this will have to remain VB.
Is there a way I can relatively easily launch the EXE pre-sync program and have it run when the ASP synch script starts?
The server is MS Windows Server 2003 SP2 / IIS 6.0 / the .NET version is 2.0.50727.3603.

I was having problems inserting a string into the following tag : <tr id="rowBulkOptions" style='<%# sBulkOptionsRowStyle %>'> Don't ask why I'm using tables sBulkOptionsRowStyle is a Public string in the aspx.vb file. Seemingly the only way I can get this to render is to put Page.DataBind() in the Page_Load, Page_PreRender etc.. However this causes me problems because Page.DataBind() binds all controls on the page. I could use <%= BUT another part of the code inserts controls into the page and apparently you can't use <%= and insert controls.Is there a way I can just say 'look, put sBulkOptionsRowStyle into the page
