I am trying to run some animation when an update panel is being updated. I have three update panels on my page and only want this to run for one of the updatepanels.
I use the follwing code which works once the page has loaded,on a button click, however I need the animation to run on the initial page load as well. I have tried adding the animation for page load in a Sys.Application.add_init(MyInit); but it doesn't work.
<script type="text/javascript">
var panelsUpdated;
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded);
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(prm_beginRequest);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(prm_EndRequest);
function PageLoaded(sender, args)
{
panelsUpdated = args.get_panelsUpdated();
}
// Called when async postback begins
function prm_beginRequest(sender, args) {
for (var i = 0; i < panelsUpdated.length; i++) {
if (panelsUpdated[i].id == "pnlAccordion") {
var panelAccord = $get('viewResults');
panelAccord.style.display = 'none';
currentPostBackElement = "pnlAccordion";
var panelProg = $get('divImage');
panelProg.style.display = '';
}
}
}
// Called when async postback ends
function prm_EndRequest(sender, args) {
for (var i = 0; i < panelsUpdated.length; i++) {
if (panelsUpdated[i].id == "pnlAccordion")
{
// get the divImage and hide it again
var panelProg = $get('divImage');
panelProg.style.display = 'none';
var panelAccord = $get('viewResults');
panelAccord.style.display = 'block';
}
}
}
</script>
Okay, this may seem silly, but on an ASP.NET .ascx control, I'm trying to use:
<input type="button" runat="server" />
instead of:
<asp:Button runat="server" />
And it's not working for me. This code:
<asp:Button id="btnBuyCat" runat="server" Text="Buy Cat"
ToolTip="Click to buy a cat" OnClick="btnBuyCat_Click" EnableViewState="false" />
renders the following HTML: (ignoring naming containers btw)
<input type="submit" id="btnBuyCat" name="btnBuyCat" value="Shopping Cart"
title="Click to buy a cat" />
That's mostly fine, except I want input type="button" not input type="submit".
I tried this code:
<input type="button" id="btnBuyCat" name="btnBuyCat" runat="server"
value="Buy Cat" title="Click to buy a cat" onclick="btnBuyCat_Click"
enableviewstate="False" />
and get this HTML:
<input type="button" id="btnBuyCat" name="btnBuyCat"" value="Buy Cat"
title="Click to buy a cat" onclick="btnBuyCat_Click" />
Unfortunately the rendered button does not work. Also, I even tried input type="submit" just to check, but unless I use the <asp:Button> I can't get it to work. I'm sure it has something to do with the JavaScript.
Using jQuery I want to be able to click an element which will also checks it's related radio button. I had this working fine until we had to add runat="server" to the radio buttons.When I apply this it prevents my jQuery function from working how to get round it, heres a simplified version of the code:HTML
<input type="radio" runat="server" id="sector1Radio" name="SectorGroup" title="Sector1" />
jQuery
$('#SomethingElse').click(function() {
$('input[title=Sector1]').attr('checked','checked');
});
I've found out that when its converted to a .net control instead of checked="checked" (as it would be usually) it is just Checked, so I changed that but on inspecting the DOM in multiple browsers, none of my radio buttons are being checked(Are there any other ways I can use jQuery to check a radio button that has runat="server"?
I need to change a standard HTML Input button to a Link button but am running into problems because the existing
code calls a javascript function. The function basically does the same as the browser back button. When I add the code and
set the property runat="server" I get a "CS1026: ) expected".
Quite new to ASP,net (VS2010) so could be going about this the wrong way.

The whole thing is in a form, and it doesnt postback when this button is clicked. Im no good with javascript, but i got a feeling thats not the problem.

MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
With jQuery, in (document).ready I assigned a click function to all buttons of my asp.net (aspx) page. When I click a button outside , the function works properly.

I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.
I know that it should be server side because the client may not have the proper javascript installed or diabled. Therefore, can someone give me some code to put in code behind that can pop up an input box and use the input after, if this can be done?
Is there any way can let me set a textbox's value before the asynchronous postback. but I don't want to add a handler for a control which caused that asynchronous postback, because there are too much control can cause that. I want to know if there is a client event would be caused before the postback.
I tried the event initializeRequest of PageRequestManager to do this, but it did not work, it seems like the request has been generated when this event was executed, the value i set in this event for textbox did not be sent to server.
here is a page I used to test
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> runat="server">

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

I have same problem, can anyone write a code project exemple
I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
Any code related to modal popup to stablise is necessary and if the values are enter correctly then modal popup should get post back.
View 4 RepliesI have an update panel which is inside a Modal Popup Extender. When I click the Refresh Report button it always calls a postback. I need to stop it from posting back.
View 2 RepliesI have a link button inside a template field of a gridview. The gridview is wrapped in an update panel. I want the link button to fire an async postback but it always fires a full postback. Why is this?
This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.

I have a textbox with an autocomplete extender.The user types in a few chars and usually gets a few to a few hundred suggestions back.And its pretty quick.This is on a formview control at the bottom by the paging. It is for a "Go to" feature.But it is returning the suggestions from the same list of search results from the previous page.(It's really the same page but I just toggle the visibility between the GridView Results and the FormView details).And if they select "All Tickets" its possible to get 5000 results from the search.
Now the autocomplete is really doing the same search as the search results did which is like 46 seconds. And then weeding it down further with the prefix (chars they type in the autocomplete textbox).I have a Return to list button. And I want the Button to interrupt, stop, cancel, abort, or somehow just not wait for the WebMethod to finish, and do a PostBack right away.Since btnReturnToList is a normal postback I can't really use PageRequestManager to check if in async or last postbackelementId or anything.
During Asynchronous postback (Ajax) will Page_PreInt() ,Page_Init(),Page_Load() events fire again?
View 1 RepliesI have an ASP .Net TreeView control that I am dynamically adding tree nodes to from my codebehind on Page_PreRender. The TreeView is populated nicely and the appropriate checkboxes are where they are expected to be. For each of these nodes the SelectAction=TreeNodeSelectAction.None. However, when accessing the TreeView CheckedNodes() collection in my codebehind after selecting a few nodes (checkboxes are selected) and clicking a submit button to post back to the server in the button click event, my CheckedNodes.count() = 0. I can not figure out why my CheckedNodes collection in the codebehind does not contain the nodes that I have checked from the GUI.
