Fire Client Side Code From Server Side At Runtime

Apr 13, 2010

I 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]

Change The Execution Sequence (Client Side Click, Server Side Click) To (Server Side Click - Client Side Click)?

Jun 22, 2011

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.

Javascript - Format Data (client-side) For (server-side)

Jul 13, 2011

Using the following script:

$("#some_button").click(function() {

var changed = [];

[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.

Example:

How can I modify the script above to generate this?

[
{
"id": "name_0",
"new": "text",

[CODE]...

Timers On Server-side - From A Client-side Piece, Call Off To A Server-side Piece

Apr 22, 2011

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.

Asp.net - Server Side Doesnt See Changes On Client Side?

Jan 25, 2012

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()));

Javascript - Register A Client-side Event Listener On A Server-side Event?

Dec 28, 2011

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'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.

Writing A Program With 1 Client And Server Where Client Side Creates A Text File

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.

Asp.net - Hidden/Shown AsyncFileUpload Control Doesn't Fire Server-Side UploadedComplete Event

May 26, 2010

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.

Example:

Page code -

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>

[Code].....

I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the <div>, making it visible at initial page render, the control works as expected.

So, is this a bug within the AsynchUploadControl, or am I not grasping a fundamental concept (which happens regularly)?

Get The Client Connection Parameters Of The Socket On Server Side?

Sep 13, 2011

I want both the client and server to write and read resp. at a constant rate (which can be configured on the GUI of the client) to the buffer.I am able to send from the client at 150 bytes per packet Now, I should be able to read also at 150 bytes per packet on the server too Since, both are connected through a socket, can we retrieve the socket params (set on the client size, like 150 here) from the server end, using the tcpServer object.Or is it must to send an initial setup packet which tells about these client params and so accordingly the server can continue?

[2005] Launch Process.Start On Client PC Instead Of Server Side?

Feb 1, 2009

I am building an internal web page which retrieves binary data from a SQL database, converts the binary to an image file, then opens the file on the clients PC.In debug mode, this works fine, because the program downloads the file successfully into a temporary directory, converts it to the image then uses System.Diagnostics.Process.Start() to launch the image file in the associated image viewing program.However, as soon as I upload it to the server, two undesired things happen:

a. The file gets saved on the servers temporary directory, instead of the client temporary directory (I kind of expected this to happen, so this wasnt much of a suprise)

b. System.Diagnostics.Process.Start() does not launch the file successfully. Nothing actually happens when it gets to this part of code, however I suspect that it is trying to launch the process on the server end, instead of the client end.

how I can get System.Diagnostics.Process.Start() to launch on the client end OR how I could get the image to just appear in the clients web browser instead?

Javascript - Client And Server Side - Make The Rows Not To Be Deleted Once The Page Is Refreshed?

Sep 7, 2011

The problem im having is that I have a table that when a user click on a button it adds a row to the table via javascript, which works fine. The problem is that if a user need to update other data the user click another button which refreshes the page and all rows the user created in the table are deleted. My question is what can I do to make the rows not to be deleted once the page is refreshed? I know some might think, just not refresh the page, but there is to much data that has to be displayed and a new query has to be generated to grab the data.

Manipulate The First Name, Last Name And Email Via Code, Preferably Server Side

I want to manipulate the first name, last name and email via code, preferably server side. But I see this is not really how this might work, using asp hiddenfields for example.

So I have to get the values for the 3 fields server side, and somehow post this to [URL] - do I need to build the script in code and submit that? Not use this javascript?

Grid View Checkbox And Javascript Not Informing Server Side Code

May 6, 2011

I'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.

Html - ASP.NET VB Nested Listviews Appearing Side By Side

May 14, 2011

I currently have a parent Listview and its child Listview displaying in the centre column of an HTML page that consists of three columns left, centre and right. And all looks very good. However I would like to display the child list view in the right column beside the parent list view.

To do this it seems I must somehow generate from the code behind page a new row in the table every time the parent Listview displays a record of its data and then some column HTML so the first child list view will appear in the right hand column.

Have a blocking and non-blocking options for connecting and possibly sending data.

C# - Dropdownlist Client-Side Filtering?

Mar 7, 2011

I'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.

C# - How To Load Client Side Before Page_load .net

Jun 14, 2012

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 ?
