I guess in simpler terms what I am trying to do is get the post value of a disabled textbox to use in a SQL insert statement when the form is posted. I need to get the value of a text box that is disabled with javascript. Ultimately I will use the value as a parameter of a SQL insert statement. I have read that I need to get the value by doing something like this:

Can I send an object from client-side javascript to server-side code via ASP.NET ?
View 5 RepliesUsing 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",

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.

I've got a bunch if labels that are changed as a user inputs data into a form of mine. The Labels are changes with js on the client side. I then after all the submission are in put use a vb script to pull the string values from these labels. The problem is the vb net part is not reading the new values of these labels. Anyway I can get it to read the new values? I have over 40 labels.

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.
View 1 RepliesI am currently adding keyboard shortcuts to our web application, so from JavaScript.So far, it has consisted mostly in triggering the click events of buttons already exposed in the user-interface.Now, I would like to add another one which redirects to another page.The new page URL needs to be generated based on elements from the source page query string.Basically, I have a date in the query string and I want to generate a new URL for the next day.
View 1 RepliesI have web page with four grid views. Each grid is hidden under a div tag. Whenever user clicks on div the data grid corresponding to the div is shown. I have binded data to the grid views at the page load only, since the data size is huge I cannot load the data binding at the page as the time taking to page load is huge. I was thinking a way that grid view gets data loaded only when user clicks on the corresponding div tag
View 2 RepliesThe 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.

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 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.

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]
View 8 RepliesI 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.

I am currently in the process of converting old "Web 1.0" code to meet current standardsIs there a better way to generate and append a client-side script other than appending a plethora of lines to a StringBuilder and then registering it to the page via ClientScript.RegisterStartupScript(Me.GetType(), "startUpScript", strScript)?Is there any other way (besides putting all of this into a global .js file) that this example can be improved? If including this into the main .js file is the "best practice" alternative, then why?

View 1 RepliesI 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.
By the way - I'd love to "learn to use .NET properly" but time is short for this project and in-depth research will have to wait.

I have a multi-line textBox disabled through vb.net :
myTxtA.enabled= false
The html it outputs :
<textarea name="myTxtA" rows="10" id="myTxtA" disabled="disabled" style="width:99%;">
...
</textarea>
That's the source code I get through the browser but the textArea is still editable in the browser. There is no javascript modifying myTxtA, and the only other reference to myTxtA in my codeFile is the following :
If somethingNotHappeningHere Then
myTxtA.ReadOnly = True
End If
I can't see why my textarea is still editable. Can the class of the div containing the textArea modify its behaviour ?
PS: I am not concerned about if the data is sent or not. I'm just looking for the textArea to be uneditable.
Edit: Same problem on IE7 and Firefox 3.5
Edit 2: When I copy all the html source from my browser into a new html file the textarea is properly disabled...

View 1 RepliesI'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True
textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
