UpdatePanel AsyncTriggers Not Working After Upgrade To 4.0?
Mar 8, 2011
Recently, I upgraded my solution to 4.0 and everything seems to have upgraded smoothly but for ASP.NET AJAX.
I have an UpdatePanel like so:
<asp:UpdatePanel ID="pnlAdvSearch" UpdateMode="conditional" runat="server">
<ContentTemplate>
<asp:Button ID="btnHidden" Runat="server" OnClick="btnHidden_Click"
ClientIDMode="Static"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnHidden" EventName="Click"/>
</Triggers>
</asp:UpdatePanel>
I have a type-ahead textbox which triggers the btnHidden_Click event on Click/Enter etc. I'm calling the following method on textbox click/enter.
function getSelectionId() {
__doPostBack(
'<%=btnHidden.ClientID%>',
document.getElementById('<%=txtLocation.ClientID %>').value
);
theForm.__EVENTARGUMENT.value = "";
I can see a postback happening and the Page_Load executing. However, the server-side btnHidden_Click never gets fired. I do not want to disable event-validation at the page-level. What am I doing wrong here?

I upgrade to VS2010 and I no longer sees the UpdatePanel control available. I do have the latest AJAX Control Toolkit but I do not see this option. In addition, I kept getting the above error. How do I resolve this issue?

I have an HttpHandler which takes care of 404 errors, which I implemented years ago as a way of doing url routing. If the request maps to a valid page, it redirects to that page. Otherwise, it returns a 404. (I know I should start using the new routing feature of asp.net 4.0, but that will take some time. I need to get this working asap.)
In IIS6, I have mapped the 404 error to "/404.ashx". In the web.config, custom errors are set up like so:
<customErrors mode="On" defaultRedirect="error.aspx">
<error statusCode="404" redirect="/404.ashx"/>
</customErrors>
and the http handler:
<httpHandlers>
<add verb="GET" path="404.ashx" type="myNamespace.PageNotFoundHandler,myAssemblyName"/>
</httpHandlers>
This has been working for years - it stopped working as soon as I changed the site to use asp.net 4.0. Everything was recompiled for 4.0, and there were no code changes.
Now, when I hit one of these urls that used to work, I get a blank page with a 404 error code. If I remove the IIS 404 error mapping, I get a regular old 404 page. It seems that the httphandler is not being called.
I have other http handler which are working fine. I figure there must be some configuration setting I missed or something like that. Naturally, this is a problem only on my production server, so I can't run it in the debugger to see what is happening.

I have an updatepanel on my masterpage. Within the contentplace holder I have my update progress control. When a user clicks on the button I load some data into a gridview. This works perfectly in FireFox. User clicks the button, the loading image in my updateprogress fires and loads the gridview. When I test this in IE 6 or 7 or in Chrome. It does a full postback and the updateprogress is never shown. So the updatepanel doesnt seem to be working in these two browsers. Code is below. Again...it works perfect in FireFox.
***From Masterpage ***
<asp:UpdatePanel ID="UpdatePanel" runat="server">
<contenttemplate>
<asp:contentplaceholder id="holder" runat="server" />
</contenttemplate>
</asp:UpdatePanel>
**From aspx page ****
<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>
<img src="ajax-loader.gif" />
</ProgressTemplate>
</asp:UpdateProgress>

I have 6 thumbnail images as asp:imagebutton instances. These are treated as triggers for asp:updatepanel control on the page which contains an asp:image control. When the user clicks on the thumbnail, the image in the asp:updatepanel's image control changes to the clicked thumbnail image. The users are also allowed to again enlarge the image by clicking on the enlarge button (this runs the lightbox function). This works fine.
Question
The problem is that the enlargement works when the page loads, however when the user select a thumbnail and then tries. The method (lightbox) does not work.I have had similar problems with javascript functions and the asp:updatepanel. Has anyone else faced similar issues?

I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.

In my application, I am using different user control for different tasks. I used an update panel to load user controls with ajax. It is working fine. I am using some other update panels inside the user controls. My problem is, the inner update panel(UpdatePanel placed inside the user control) is not working properly.

I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.

I am building a website using ASP.net ajax. there are 3 <asp:panel> controls in the page and each contains a number of dynamic linkbuttons. these panels are contained in a <asp:updatepanel> control the page_load event fills out the first panel with linkbuttons and assigns cooresponding commandName commandArgument for them, that works. then the first panel's linkbuttons triggers the command and fill out the second panel with linkbuttons, that works too. then the seond panel's linkbuttons are supposed to fill out the third panel with linkbuttons, but that doesn't work anymore, and it seems like doing the page_load event again and filling out the first panel and the second panel's linkbuttons disppear, just like the first time the page is loaded.

I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?
Also if i can ask another question, I'm also wanting to know whether the updatepanel can support feed-in like facebook ? What I'm wanting to do is have something that updates the screen (like the update panel), and items within this panel contains links. When the user clicks on the link it shows a modal div, giving the user options to do some updates. Once the user clicks submit, then this makes a call to the server to update the details then also update the panel. Within the panel I also want to move some of the div elements using javascript (causing the drag and drops to save to the database).

I found this thread while trying to resolve my issue unfortunately this I can't seem to figure out the problem since I already have everything the way it should be.
I've got 3 updatepanels that each call a function on a .js file setup like this:
<asp:UpdatePanel ID="upPnlGeneralinfo" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
<ContentTemplate>
<script type="text/javascript">
Sys.Application.add_load(BindPageLoad);
</script>
Each have a different ID of course. Whenever a control calls a postback within the update panel it works, however in the js file I added a console.log("running the js file") and I can see that it's being called three times meaning it's all three updatepanels are being refreshed instead of just the one.
All the triggers are inside each of the respective updatepanels so I shouldn't need to add any triggers (I did just to make sure and it makes no difference). Shouldn't the UpdateMode=Conditional resolve this?
Also worthy to mention, none of my code behind ever calls any updatepanel.update(). I tried adding that for each control to their respective panels and that also made no difference.

I have an update panel on my page with some links that have onClick events that trigger a JQuery box to pop up. This works fine unless an AJAX postback has occurred. I saw some code on another post:
Page.ClientScript.RegisterStartupScript(TypeOf(Page), 'ajaxTrigger1', 'Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);', true);
Page.ClientScript.RegisterClientScriptBlock(TypeOf(Page), 'EndRequest1', 'function EndRequestHandler(sender, args){AsyncDone();}', true);
which I have used but it doesn't seem to be working. I keep getting AsyncDone is not defined.

I'm using fancybox to display the contents of a div when clicking a link. This works using the code below:
<a id="popupTrigger" href="#popup">popup trigger</a>
<div style="display:none">
<div id="popup">
<asp:UpdatePanel ID="HerkomstCodeUpdatePanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
This content displays inside fancybox.
<asp:TextBox ID="CurrentTimeTextBox" runat="server"></asp:TextBox>
<asp:Button ID="RefreshContentButton" runat="server"></asp:Button>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</div>
And the JScript:
$(document).ready(function () {
$("#popupTrigger").fancybox({
autoDimensions: false,
height: 250,
transitionIn: 'elastic',
transitionOut: 'elastic',
width: 400
});
});
Now what I'm expecting it would do is that when you click the button (which is displayed inside fancybox) it would update the textbox and do whatever I define it to do in the codebehind. Unfortunately nothing happens when I click the button.
I've tried to trigger a __doPostback myself passing the ClientID of the updatepanel and/or the button itself. I can't seem to trigger the event in the codebehind however.
The thing is if I remove the fancybox, the updatepanel works as expected. So I am guessing if I can somehow find out what eventhandler logic is behind the button before I create the fancybox, I might be able to recreate the eventhandler logic after attaching fancybox? I just can't find it anywhere...
I am using ASP.Net WebForms 3.5 and JQuery 1.4.1
Update
I got it to trigger the codebehind button_click event by overriding the clientside click event on the button using the code below. The key is in using the name of the button as the sender object for the __doPostBack event. The only problem that remains is that all other values aren't posted back anymore. If I type anything in the textbox, click the button, my codebehind doesn't know what's in the textbox anymore.
$("#popupTrigger").fancybox({
//.... other options,
onComplete: function () {
$("#RefreshContentButton").click(function () {
__doPostBack($(this).attr('name'), '');
});
}
});

I am loading the calendar inside the update panel. when the page loads, the calendar renders the day events for current month.
Curvery corners works fine on Firefox, Chrome and Safari even after the page load but not on IE.
here is the code:
<script type="text/javascript">
Sys.Application.add_load(AppLoad);
function AppLoad() {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequest);
//Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequest);
}
function pageLoad() {
var isAsyncPostback = Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack();
if (isAsyncPostback) {
tb_init("a.thickbox, area.thickbox, input.thickbox");
}
else {
var btn = document.getElementById("ctl00_contentBody_BtnReload");

I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.
I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..
<asp:UpdatePanel ID="UpdatePanel1" runat=server><contenttemplate><triggers><asyntrigger ID= "Submit"> /> /> />
<asp:updateprogress ID="Progress1" unat=server AssociatedUpdatePanelID="UpdatePanel1"><Progresstemplate>Progress.... />/>
<asp:button ID= "Submit" runat=server >
I have nothing for updateprogress in code behind. Am i missing or doing somethign wrong here?
