I have a div with "id=ShowDetails". In my javascript I have this:
$(document).ready(function () {
UIactions();
});
function UIactions () {
$('#ShowDetails').click(function () {
alert("bingo");
}
});
The div is inside the update panel that gets posted back. When the page loads, if I click the div, I get the bingo but after the postback, I don't.
I am trying to add some JQuery animations before and after every postback request is made inside my UpdatePanel. What I have so far is something like this:
<script type="text/javascript">
$(document).ready(function () {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
function EndRequestHandler(sender, args) {
if (args.get_error() == undefined) {
// End Request (1)
}
}
function BeginRequestHandler(sender, args) {
// Start Request (2)
}
$('.MyButtons').live('click', function () {
// Before request (3)
});
});
</script>
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:Button runat="server" CssClass="MyButtons"/>
</ContentTemplate>
</asp:UpdatePanel>
Let say I want to put some animation code at (3) that will be executed and then proceed with BeginRequestHandler function. How should I do that? Because right now the whole process executes 3,2,1 and I dn't know how to add that delay between steps 3 and 2. In other words I want to execute step 2 manually at step 3. Don't really want to use hidden buttons to do that.
I want to load a popup when a user clicks a button. The buttons are images located inside a tabpanel. The first time the page is loaded the helpEvents DOES display the popup and the 'click' popup. Then I navigate to Tabpanel tab2, and the helpTickets button doesnt work (doesnt even display the 'click' popup) Then I navigate back to Tabpanel tpEventDetails, and the helpEvents button doesnt work anymore either(and also doesnt even display the 'click' popup anymore) So I think something gets lost in the updatepanel on callback...but what? and how to fix it?
default.aspx
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<cc1:TabContainer OnActiveTabChanged="TabChanged" ID="tabContainer" runat="server" ActiveTabIndex="0" OnClientActiveTabChanged="ActiveTabChanged" Width="100%">

ImageButton inside Datalist inside update panel is not firing in my asp.net web page. what should i proceed??
View 1 Repliesi have one master page and the ContentPlaceHolder that are inside UpdatePanel. I have too, buttons in master page thad feed the ContentPlaceHolder e update the UpdatePanel. When i click on any master page button, it load one UserControl inside ContentPlaceHolder. But inside one of this UserControls have a Button, that when i click on, it dont fire the click event.
MasterPage code:
[Code]....
Code that load UserControl inside ContentPlaceHolder
[Code]....
Code that contains the button that dont fire:
[Code]....
Obs: I tried sign dynamically the button, but dont works. And when i click on button, the unload method of UserControl begin called.
I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem
My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs.
I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator.
Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing.
I have a asp.net page with a button, the event the button needs to perform on it's click event needs to vary, dependant on what options are selected further up the page. The button itself is included in the master page, and it's actions are affected by selections made in the child page.
To do this, I have a method in the master page, that is called by the child page, when a users presses a button, that passes the Eventhandler to be used by that button, that is then assigned to masterpage eventhandler for that button:
public void assignEvent( EventHandler saveEvent)
{
this.SaveButtonEvent+= saveEvent
}
Then, when the save button on the master page, it calls that eventhandler
protected void save_Click(object sender, EventArgs e)
{
if (this.SaveButtonEvent != null)
{
this.SaveButtonEvent(this, e);
}
}
The event handler is assigned ok in the first section of code, however because pressing the save button causes a postback, the SaveButtonEvent event handler is set back to being null, and so nothing happens.
How can I preserve the contents of SaveButtonEvent Event Handler during postback, or is there a better way to be doing this?
EDIT:
I can get this to work by saving the EventHandler to the session, but this doesn't seem like a great idea.
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:

The codebehind:

I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago.
We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too...
I've got a textbox being used to enter a password inside a wizard control. I'm trying to get a password strength meter working with it.
Unfortunately, the password box isn't visible until step 4 and this means that I can't register the event handler onload() and putting some JS next to the PW box to register the event handler doesn't seem to fire. I'm guessing this is due to the contents of the wizard being loaded through an AJAX postback.

I have DropDownList inside GridView. Now I would like to add event handler for dropdownlist which would react on SelectedIndexChanged.I'm nesting DropDownList inside GridView by using RowDataBound event for GridView.(http://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx) and tell me how to add event handling for dropdownlist
View 3 RepliesI've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.
It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.
After selecting an item, the rendered HTML looks something like:
[code]....
I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.
I've added Dropdownlist in Gridview at RowDataBound event. The code is:

I'm learning asp.net page life cycle. I find an article on MSDN [URL] It says that If the request is a postback, control event handlers are called. After that, the Validate method of all validator controls is called, which sets the IsValid property of individual validator controls and of the page. And the picture in the article also says validate fires after event handling. If this is true how can I get status of validator when I handling the event?
View 3 RepliesI have problem with user control: MyCollection : UserControl
MyCollection contains:
[code]....
Works fine unless I register event for some button:
button1.Click += ...
When click on button, nothing happens - page does postback, refresh but event handler method is not executed. Generated HTML is bit strange. Every page control has correctly generated ClientID including parent container ID.
Button in this collection MyCollection has odd ClientID - itemsAddresses$button1
In Page_Load, Request["__EVENTTARGET"] is an empty string.
IS there some way I can find out which button triggered the postback before hitting the buttons event handler?
I have created an event handler for the OnSortCommand of DataGrid:
<asp:DataGrid id="dtgBatches" runat="server" Width="100%" CssClass="intTable" EnableViewState="False" DataKeyField="bat_GUID"
GridLines="Horizontal" AllowSorting="True" AutoGenerateColumns="False" AllowPaging="False" >
<SelectedItemStyle BackColor="#FFFF99"></SelectedItemStyle>
[Code]....
The problem is that the handler never executes.
The registartion for the handler is done as below:
private void InitializeComponent()
{
this.dtgBatches.SortCommand += new System.Web.UI.WebControls.DataGridSortCommandEventHandler(this.dtgBatches_SortCommand);
}
Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?
View 2 RepliesThis is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton
How do i run a javascript event after a postback within an updatepanel
View 3 RepliesMy problem is very simple: I have a chart inside an UpdatePanel (I'm using AJAX) and 2 RadioButton in which AutoPostBack=true.When I click on my "generate chart" Button, the chart is well painted on the page but the AutoPostBack of my 2 RadioButtons seems to stop firing. That is to say, after painting, If I click on my RadioButton the postback doesen't works!I need to set some kind of trigger related to the chart?
View 5 RepliesI have a checkbox inside a update panel. Based on certain conditions, I set the autopostback property to true and also attach a event handler as below
chkBox.CheckedChanged += new EventHandler(this.ChkBoxChaned_Click);
But when the checkbox is checked/unchecked, autopostback happens but the event handler does not get hit.
I have updatePanel in my ASP.NET 2.0 (migrated from ASP.NET 1.1) web app. It doesn't work as it always postback instead of callback. I already set<xhtmlConformance mode="Transitional" /> but still not working. Previously, it just working.
