I think it's generated from CollapsiblePanelExtender with name cpeDetails. And I see you can pass number of events to it, wich is now null (third argument). What should I do to set add_ended event there?
I have a CollapsiblePanelExtender (ext1) with a second CollapsiblePanelExtender (ext2) within it. Is it possible that when ext1 is extnended that it checks the value of a dropdownlist within ext1 and depending on the value of the ddl then extend ext2?
Currently I am implementing code from this example. In my aspx file, I have Label1 and Textbox1 defined. In my aspx.cs file, I am setting the Label1.Text property to a random string in the Page_Load method.
In the .js file I have included, I have: var Label1, TextBox1; Sys.Application.add_init(AppInit); function AppInit(sender) { Label1 = $get('Label1'); TextBox1 = $get('TextBox1');
I am wondering how to add a javascript event handler using asp.net ajax. I need to add event handlers after ajax update because Jquery plugin to sort tables doesn't work and the onload method to display a screen keyboard does not trigger as well. Is there a way to do that? Maybe I need to switch to some other ajax library or/and try Asp.Net MVC to accomplish?
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?
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 have a aspx page that, when loading, will initialize a class called, Bill :)
When Bill is initialized, the aspx page will wire a function to a handler of Bills.
When that function in Bill is fired, I would like to call a javascript function in the aspx page, but that is where I am having difficulties...
I have tried ClientScript.Register and all of that, but nothing is seeming to work. As of now, I am simple trying to get the function to fire an alert.
I have placed an <asp:Button></asp:Button> inside of an asp.net control in a subdirectory called "Controls".In the control's codebehind, I put an button_click() handles button.Click sub routine.The button is meant to grab information from a form, and then submit that info to the DB.The issue that I'm having is, the button just seems to refresh the page, and return to the page's original state (it loads the control the page should load on startup) and when I try it in Debug mode, the click event is never called, it's as if It was not there at all.Does anyone know what might cause something like this to happen? It's definitely a first for me.
I have a web form in which I create many controls including a submit button dinamically.
I want to check a condition in the button's click event and if it comes true, call a javascript funtion to show an alert. but the problem is when I use :

Is 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?

I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I have implemented a CollapsiblePanelExtender with a button that collapses/expands a panel. I also have a javascript function that can collapse the expanded panel when a certain condition exists somewhere else on the page.
The problem I am having is when I programatically collapse the panel, the extender is not aware, so the Collapsed property remains false and the CollapsedImage and CollapsedText are not updated. The next time I click the button, the extender is updated to a collapsed state, but nothing happens on the page because the panel was already collapsed. It is just resynchronizing the Collapsed, CollapsedImage, and CollapsedText properties to match the panel's already collapsed state.
Is there a way I can update the Collapsed, CollapsedImage, and CollapsedText properties in javascript to match the actual state of the panel?
