I want a Javascript function to be called automatically after the UpdatePanel has finished updating its contents. I don't want to use:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();
[Code] .....

I am having trouble with getting the Jscroller2 too work inside an updatepanel after I have added a marquee as a newsbanner. - (The marquee is running outside the updatepanel)Beforer the marquee was present I could trigger the JavaScript with:
[Code]....
Now the Jscroller2 only works when the page is loading the first time and not after the updatepanel has updated.So my question is how do I get the Javascript to fire after the updatepanel have updated when a marquee is present?

I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.
Whenever I click on a checkbox the click event gets triggered and I make a call to
__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.
is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.
The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.
so how can I then, make this performance faster?

I put the following javascript code inline but it doesn't trigger after the updatepanel is done with its postback:
function EndRequestHandler(sender, args) { alert("this should work"); }
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
The source code:
<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of what im trying to do
<script type="text/C#" runat="server">
protected void LinkButton1_Click(object sender, EventArgs e)
{
Panel1.Visible = true;
}
</script>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Text="Show Panel"></asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
<asp:Panel ID="Panel1" runat="server" Visible="false">
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
this is the javascript error that gets thrown when clicking on the "LinkButton1" link. This error comes from the javascript that is generated by the asp.net ScriptManager control
Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder1_UpdatePanel2'

So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.

I have a menu of buttons inside an UpdatePanel (UPD_Menu) so that buttons can be enabled/disabled without refreshing the entire page. When a user signs in, the Sign Up button is disabled and the Profile button is enabled. Likewise, when the user signs out, the Sign Up button is enabled and the Profile button is disabled.
Inside this UpdatePanel (UPD_Menu), along with the buttons, is a ModalPopupExtender that is fired by the Sign Up button (TargetControlId="BTN_MenuSignUp") that pops up a dialog Panel (PNL_SignupProfile) that contains yet another UpdatePanel (UPD_SignupProfile) that contains a Submit button as well as a Cancel button (CancelControlId="BTN_SelectCancel").
The behavior I am getting is when the user clicks no other button than the Sign Up button, the dialog (PNL_SignupProfile) pops up and is modal. The Submit button closes the dialog and makes the once-hidden panel appear under the menu of buttons. This is not good as only the inner UpdatePanel (UPD_SignupProfile) should be updated without affecting the outer UpdatePanel (UPD_Menu). The Cancel button works as it should by simply closing/hiding the dialog.
If a user clicks any other button in the menu first, nothing happens ( no codebehind yet) but when the dialog (PNL_SignupProfile) is shown, the Cancel button causes the hidden Panel (PNL_SignupProfile) to appear under the buttons. I've tried many different things to no avail...including putting the dialog panel in different places and even controlling the ModalPopupExtender from code.
The only code I have so far is for handling the signin/signout and enabling/disabling the signup and profile buttons based on user signin. There is no code yet to handle the menu of buttons nor the submit button of the popup dialog.
Here is the code:

I'm having a problem with a dropdown throwing an error:
Uncaught Sys.WebForms.PageRequestManagerServerErrorException:
Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.Only Sometimes.
I am using an updatepanel, with a bunch of dropdowns that have an onchange for Javascript, that use ajax (partial page postback). The problem is: I have two dropdowns at the top (also inside the updatepanel) that let me change the current month or year. Sometimes...they change the page (response.redirect), and sometimes they throw that error above. Also, they are the Only two buttons on the page that aren't doing an "onchange" and then ajax stuff....they are actually posting back the entire page to the server (or trying to).

TThis time I'm facing some unusual behavior with a web page that I'm developing. I have a table with several controls and gridviews and stuff. At some point of the table, i have to show some rows (they were hidden) when the users clicks a button. I was doing this with a PlaceHolder, but now i have to do it without the postback being displayed. I thought: "That should be easy, all i have to do is to put the PlaceHolder inside an UpdatePanel, and that's it" but no, no no nooo!! NOTHING IS THAT EASY!!! It actually works but it puts the hidden rows at the top of the page, not where they suppose to go!!My code is the following:
<asp:UpdatePanel runat="server" ID="uplAutoridadesAmbientales">

I have a PopupControlExtender inside of the UpdatePanel. I use it to edit some of the values on the website.
Basicly it looks like this. If you have PopupControlExtender inside of th update panel whenever a user triggers a partial postback javascript creates the popup panels outside of the UpdatePanelControl - to make sure they are always on the top of other elements. So after every postback you get more and more elements with the same clinetIDs.
Here is a code from Firebug - you can notice Panel1 and all the controls inside of it being generated 3 times when i load a page (once) and twice after two partial postbacks:
[Code]....
Oh and i use it actually inside the listview that itself is embeded in the update panel so i cant really use it outside of the update panel.

The first one works fine, but the second one does not fire when click on it. The code is as follows:
