I want to restrict the user if they select the language which is already selected by displaying alert msg using JQuery.
Is there any event which fires before the change event.
I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
why the erroneous page_load event is firing ?

I've got the an bit of ajax and the succeed runs twice. I've got a global var that I used to keep track.
Code:
var counter = 0
$('#txtLookupText').keyup(function(event) {
$(document).ready(function() {
});
$.ajax({
type: "POST",
url: 'ContactLookup.aspx/LookupContacts',
data: "{'inputStr': '" + $('#txtLookupText').val() + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
AjaxSucceeded(msg);
},
error: AjaxFailed
});
});
function AjaxSucceeded(result) {
if (result.hasOwnProperty("d")) { result = result.d; }
var li = ''
for (i = 0; i < result.length; i++) {
li += result[i].FirstName + ' ' + result[i].LastName + '
}
counter += 1
alert(counter)
}
function AjaxFailed(result) {
alert(result.status + ' ' + result.statusText);
}
I moved the counter to the POST and only got one alert box. In the succeed, I get 2 alert boxes in succession.
There 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.
why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
View 3 RepliesI have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
Below code, i need the RegularExpressionValidator on key press event/On change event. I need to validate same time while user doing input.
Code:
[code]....
in aspx i written as follows
<ajaxToolkit:ComboBox ID="cmbAddressAlias" runat="server" DropDownStyle="Simple" AutoCompleteMode="Suggest" CaseSensitive="false" AutoPostBack="true" RenderMode="Inline" Width="170px" CssClass="cmbProvince" OnSelectedIndexChanged="cmbAddressAlias_SelectedIndexChanged"> </ajaxToolkit:ComboBox>
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
How do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Base Class:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs)
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
RaiseEvent FirstLoad(sender, e)
End If
End Sub
Derived Class:
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad
'Stuff here happens before controls load but only on first page loads'
End Sub
I thought I was coding a change event correctly, yet somehow i'm not getting any resultI made the simplest of examples to accomplish what i want

i have a text box with textchanged event and autopostback=true and textchanged event which takes user to other page with textbox's chanegd value.i have applied a jquery to the textbox. when i start entering alphabets, a listofitems is show.eg:if i type the, I GET HTE HOTEL,THE MALL,THE BEACHs soon as i click on any thing(say THE HOTEL), asp.net takes me to the otherpage with only THE as text. and not THE HOTELthis is happening as the event is raised when i click on a choice which is as good as i am clicking outside of textbox. thus the asp.net working is fine.
View 3 RepliesI have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed.
<asp:TextBox id="myText" runat="server" />
<asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator>
$(document).ready(function(){
$('[id$=myText]').bind('change',function(){
//do something........
and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception.
i would like to have an event fired in jquery, if the validators of my page change their states.
This is my usecase:
In an Adressform the Validators all are hidden. If i submit the form, the get displayed. Now i want to fire a jQuery function, which renders all rows (not the inputfields, but their parents) with a red border (means add a css class) if i now change the field and the validator hides i also want to hide the border around the input's parent
i don't want to have a timer checking every 100ms the displayed validators (which would work perfectly), but i want to listen only to the show/hide events of the validators
how i can add a listener to the change events of a validator?
I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.

I am using fullCalendar and I'm able to populate the calendar with events very easily. And I undertsand the best way to add events to the calendar is through the database. What I need now is to catch and populate an edit event form after the user clicks an event.
View 1 RepliesI have an aspx page that is wrapped with an UpdatePanel control, users can post comments and delete them later, when the user clicks the delete for the first time it deletes successfully but if he wants to delete another comment, it works only after two clicks on the button.the delete button is inside a web user control that is added dynamically at run time.
View 1 Replies<asp:LinkButton ID="LinkButtonNewServicesCategory" runat="server"
OnClientClick="this.disabled=true;return false;"
style="float:left;margin-right:5px;" CausesValidation="False">new services category</asp:LinkButton>
The intent is that when the LinkButton is clicked, it disables itself and returns false to prevent the postback (this control is used as a trigger for an animation).
which event fires first in the page life cycle and why?
View 1 RepliesI was under the impression that static files (CSS, images, @font-face files, etc) bypassed ASP.NET completely, and were served directly by IIS. However, my BeginRequest event handler is being called for every HTTP request, including those for static files. This concerns me because I'm creating an Entity Framework data context to be used for the lifetime of each request in that event handler. I don't want to create those contexts if they're never going to be used.
I'm using IIS 7 on Windows 7 Ultimate with so special handler mappings defined. Do I have it wrong? Should these events be firing?
