I'm using vb.net 2005. Here is my code:

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 = [];

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]...
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.

View 1 RepliesI 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:

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 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 have a form where a user can delete a record, and I want a pop up message where the user has to click okay to confirm the delete.
Delete button:
<asp:Button ID="btnDelete" runat="server" Text="Delete" UseSubmitBehavior="false" OnClick="btnDelete_Click" OnClientClick="confirmation();" />
Confirmation function:
function confirmation() {
var answer = confirm("Are you sure you want to delete? This action cannot be undone.")
}
So right now, clicking the delete button executes the btnDelete_Click Sub in the code behind regardless of whether you click okay or cancel in the pop up box. I know I can add if (answer) { -- some code here -- } in my javascript function, but is it possible to use javascript to execute code from the codebehind? Or is there another way to do this?
I am working with a .Net 1.1 web application. There is a Save button that, when clicked, will pop up the Javascript confirm box. Once the user clicks OK a long running process is kicked off. We would like to show a busy indicator when the user clicks the OK button of the confirm dialog.
View 3 RepliesI want it so that when a user clicks on a radio button, it gives them an OK/Cancel javascript dialog box - if they click OK the code for the radio button will run, if they click Cancel, nothing happens.For a button I can easily do this by changing the OnClientClick property, but with a radio button I can't get anything to work properly.
I try this:
rbNo.Attributes.Add(
"onclick",
"return confirm('This Are you sure');")
but even if they click OK, nothing happens.

I am working on a VB.NET web application. When someone successfully changes their password I want to show a popup message that lets them know it was changed successfully. After they click OK I want to redirect them to the main page. Code looks like this:

Response.Redirect("MainPage.aspx")
Why does the redirect happen and the alert popup never displays?
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]

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?
