I have two click handlers hooked on the click of an anchor. I want the first handler to be able to cancel the propagation of the event to the 2nd handler. Also, I want to be able to cancel the default click behavior of the anchor.
Problem is, StopPropagation is not found as a method on the "e" object passed to the event handler. Why is StopPropagation not found?

I had thought that returning false would keep my asp.net OnClick even from firing, but it still does. I've confirmed that it is getting to the return false section of code using alerts. Is there anything I can do to stop it from firing using jQuery/javascript?

The script works fine in firefox and chrome but not in IE7/8. It is normally supposed to send a string to the openid_identifier textbox once the google or yahoo select box is clicked.
How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)
I have a JQuery Dialog that is opened when a button is clicked. The first time around, it should do a postback, but when the dialog closes and I click the refresh button of the broswer, it sends the data again and duplicates the data I just entered. Should I add a return false somewhere so it doesn't postback when the dialog is closed. Here is the script:

View 8 RepliesI am calculating discount at text changed event when user enters the discount%. To edit when i load the data from table using dataset i do not get the correct data as it is in the database. For ex if quantity is saved as 5000.00 in table and when i try to fetch it.. I am getting it as 500000. Instead of 5000.00. Is it because of text changed event? How do i resolve this?
View 1 RepliesCurrently users select a record in a gridview and click on the delete button. Delete button passes certain variables to identify the record, makes a SQL connection and then deletes the record by executing a stored procedure. This is way the delete button's code behind works. Now we need a confirmation box if a certain flag is False. If the users select YES then they should be able to delete any way otherwise clicking on Cancel should stop the operation. I don't want to use the onClientClick event of the button like many examples on Web show, instead I am using the jQuery, that uses the button ID and pops up a confirmation dialog. The issue I am having is even if the Cancel button on the confirmation dialog is clicked it still goes on to run the code behind, executes the stored procedure and deletes the record. The browser being used is IE 7.0, how do I stop the button from running the code behind in the button_click event if they select cancel?
I have tried return false, e.preventDefault();event.propagation, event.returnValue = false etc but can't stop it. Here is the jQuery, that goes to the webservice when clicked and determines whether to display the confirmation or not when another stored procedure returns the record count of 0 or more. Like I said it works fine in getting the flag value from the SQL but does not stop at the client level and continues on to the code behind of btnDelete.
$(function() {
$("#btnDelete]").click(function(e) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "WebServices/myServices.asmx/ConfirmDelete",
data: "{}",
dataType: "json",
error: function(req, msg, err) { alert(req, msg, err); },
success: function(msg) {
if (msg.d == 0 && !confirm("Do you wish to delete this record?")) {
event.preventDefault();
return false;
event.returnValue = false;
}
}
});
});
});
Overview
I have 3 update panels on a page, each of them have UpdateMode="Conditional".
UpdatePanel1 contains listbox1 (AutoPostBack set to true) which is populated on pageinit from the DB.
UpdatePanel2 contains listbox2 (AutoPostBack set to true), this panel has AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox1 in UpdatePanel1.
UpdatePanel3 contains textboxes that will hold the details once an item has been selected from listbox1 and listbox2, this panel has an AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox2 in UpdatePanel2.
In the codebehind, the SelectedIndexChanged event for listbox1 populates listbox2 and the SelectedIndexChanged event for listbox2 populates the textboxes in UpdatePanel3.
The problem
When the page loads listbox1 is correctly populated, I select a value from listbox1 and listbox2 is populated, great, no problem so far. When I then select a value from listbox2 the SelectedIndexChanged event for listbox1 is firing, I assume that as this populates listbox2 again it is clearing the selected value for listbox2 as the SelectedIndexChanged event for listbox2 is not firing.
How do I stop the SelectedIndexChanged event for listbox1 in UpdatePanel1 from firing when I select a value from listbox2 in UpdatePanel2 ?
I am using the jQuery Dialog in ASP.NET. I have it working fine with the exception of when I click the OK button in the dialog and if an error occurred I want to show the error in the label. By the time the dialog closing event is fired it is too late. How do I still show the dialog if an error has occurred. I don't want to close the dialog when there is an error.

View 1 RepliesThere is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
I have a link button in a repeater control. the li element is drag and droppable using jquery. when the page loads the the link button works perfectly, the jquery that is attached and the server side code both execute. when I perform a drag and drop then click on the link button it doesnt not fire. when i click it a second time it does fire. If i perform 2 or drag and drops in a row the link button doesnt fire a as many drag adn drops as i before it will fire. for example if if perform 3 drag and drops then it will take about 3 click before the events are fired.

View 2 RepliesI'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.
