AJAX :: HoverMenuExtender Stops Working After Async Postback In Updatepanel?
Feb 23, 2010
I've got a problem that after i refresh an update panel all the HoverMenu's stop displaying, it still calls the WebMethod which returns valid html and the panel is displayed, but it content of the panel isn't displayed on the browser.
I've created a single page to demo this problem:
aspx
[Code]....
vb.net
[Code]....
The demo shows the hovermenu working until you click the update button then it stops showing the content, although it is still calling the WebMethod onhover.
I am using VS2008, .net Framework 3.5 and toolkit 3, 0, 30930, 0
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?
I have a series of div's inside an update panel, these divs have a margin-bottom defined in css. In IE8, when I do a async postback these margins are all removed. All the other styles are fine. If I turn on compatibility mode this does not happen. In Google Chrome the margins are maintained correctly after the async postbacks.
We have an updatepanel in our site and there are a number of linkbuttons in it. Please note that the site works fine in all browsers without proxy the proxy changes the url from for instance [URL] to 0-[URL] it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is "Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; Tablet PC 2.0; InfoPath.1; .NET4.0C; .NET4.0E) Timestamp: Sun, 13 Mar 2011 20:38:58 UTC
Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.

I have no idea what goes wrong here, it seems that IE can't parse the response?
I have a radiobutton that triggers the updatepanel to display or not..
when the page loads, i can select yes adn it displays, i can select no and it disappears.. i hit yes it reappears.. but after like the 3rd time going back and fourth testing the functionality, it stops displaying all together.
Is there something i need to look at to find out what is going on?
I know about Always vs. Conditional, I just need to know exactly which update panel's data needs to be refreshed (not taken from app tier cache) on the serverside.
I have placed a user control inside update panel after doing asynchronous postback of page associated js file of that user control is not working so that is there any method to exclude a control from updatepanel in another word i don't want to post that user control.
<asp:UpdatePanel ID="upPnlAnswerList" runat="server"> <ContentTemplate> // another code that required to placed inside updatepanel <div id="miancontainer" class="containerr" <klmsuc:Share ID="shareUserControl" runat="server" /> [code]...
We have an updatepanel in our site and there are a number of linkbuttons in it.Please note that the site works fine across all browsers without proxy the proxy changes the url from for instance www.mysite.net to 0-www.mysite.net.edu.net it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is
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.
Now i am having two dropdown one is asp dropdownlist and 2ND is MultiSelect-DropDownList-with-CheckBoxes. 2nd dropdown is populating on selected value of first.On page load it works fine. Now, on change of value in dropdown, selected index change 2nd dropdown (MultiSelect-DropDownList-with-CheckBoxes) fills but i see a list box instead of dropdown.
I have a GridView in which I have item,Edit ,Footer and Empty Item Template , and also a hovermenuextender to show Edit/Delete link on row hover. when my page opens if it doesn't have any data it show empty row , when user enters data and click on Add button it save's the data and load the grid. All works fine in IE and firefox but not in google Chrome.
After saving data in chrome all links stop working , but when i reload the page it workes fine if i remove the hovermenuextender it works fine in chrome also, So i think hovermenuextender creating problem in chrome when it's added at runtime(if empty grid comes hovermenuextender will be added after data saved)
I am using VWD 2008.. I have a RadioButtonList with two options.
[Code]....
I also have an UpdatePanel
[Code]....
When the LoadingOption change it then has some code behind that at the moment changes the <asp:Literal ID="ItemName" runat="server" /> text.
If I don't have a Radiobutton selected when the page loads then all works fine. i.e. I can select either radiobutton and the ItemName updates correctly.... Whats the problem you may ask ????
Well I want to have one of the Radio buttons selected when the page has been loaded (like a default setting). So I do this <asp:ListItem Text="1kVA" Value="1kVA" Selected="True" />........ Here is my problem, When I select the other option (7kVA) the ItemName updates fine BUT if I then select the first option (1kVA) the ItemName does not update. I added another button that just does a postback. When the button is clicked the ItemName updates correctly. OK, fine but I don't want that. I want to be able to click on one option and the ItemName updates then click on the other option and the ItemName updates.
Have I missed something out ??
By the way if I set the <asp:AsyncPostBackTrigger ControlID="LoadingOptions" /> to <asp:PostBackTrigger ControlID="LoadingOptions" /> then it works how I want it apart from the reloading of the page, I would like it to update in Async Mode so it is seemless and no page reload.
I'm using ASP.Net 2008 and C# and Ajax. I have wired up my ajax updatepanel to update the buttons within them in the gridview control's RowCommand event. However, at the end of this event, I call the Response.Redirect(commandArgs[2]); to open either Word or Adobe docs that user selected. And this line of code stops my Ajax updatepnael to update my 2 buttons' enabled properties. I thought maybe there is another way to open docs that won't interfer with my Ajax updatepanel and what will that be?
in my Site i have 3 updatepanels.In the 1 is the gridview. with templatefield in this is the imagebutton. ImageButton has commandname "Select" want to register the ImageButton as AsyncTrigger for the other Updatepanels 2 and 3
I'm working on adding a todo list to a project system and would like to have the todo creation trigger a async postback to update the database. I'd really like to host this in a usercontrol so I can drop the todo list onto a project page, task page or stand alone todo list page.
Here's what I have.User Control "TodoList.ascx" which lives in the Controls directory.
The script that sits at the top of the UserControl. You can see where I started building jsonText to postback but when that didn't work I just tried posting back an empty data variable and removed the 'string[] items' variable from the AddTodo2 method.
<script type="text/javascript"> $(document).ready(function() { // Add the page method call as an onclick handler for the div. [code]...
I can have a control that can be used to display multiple todo lists and create a brand new todo list as well.When I click on the #divAddButton I can watch it build the postback in firebug but once it completes it runs the error portion by alerting 'error'. I can't see why.
I'd really rather have the response method live inside the user control as well. Since I'll be dropping it on several pages to keep from having to go put a method on each individual page.
I have a problem with an amimated gif inside an UpdateProgress which is linked to an UpdatePanel. Basically the gif displays for a few seconds then justs stops and then a few seconds later the page displays. Reading some other posts it and putting in some debug info I can guess it is because the postback is returning a lot of markup, so it seems the postback has stopped and the gif freezes while the markup is being sent/being rendered. Is there anyway to keep the gif 'running' while all this markup is doing its thing?
I am using the RegularExpressionValidator control inside an Update panel. It works perfectly when I load the page the first time, but after a postback it doesn't work.
Let's say that after the first postback I include invalid characters in the textbox and run an new post back, I shows that the result is invalid...
I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
[Code]....
I have also tried flat out writing the function call to the page:
[Code]....
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.
I want to provide status updates during a long-running task on an ASP.NET WebForms page with AJAX.Is there a way to get the ScriptManager to execute and process a script for a web service request concurrently with an async postback? I have a script on the page that makes a web service request. It runs on page load and periodically using setInterval(). It's running correctly before the async postback is initiated, but it stops running during the async postback, and doesn't run again until after the async postback completes.
I'm trying to create a modal popup that has multiple buttons that a user will click to choose options. This is all well and good but when the user clicks an option it fires a full postback. The modal opens async, but I can't get it to hide async. Heres some code:
I have following code and when I select from my drop down list the progress controls do not show and my grdiview is not being filled either. If I leave out the update panel from my code things are working fine.
I am using asp:ScriptManager and asp:UpdatePanel to populate a DropDown , and for every field need to display hits in div.In order to Implement the hint I am using JS, it works fine unless I started to populate a dropdown based on another one.
here is some code lines from page and JS
<asp:ScriptManager ID="sm" runat="server" EnablePageMethods="true"></asp:ScriptManager> <asp:UpdatePanel runat="server" ID="up0"> <ContentTemplate> <dd><asp:DropDownList runat="server" ID="CCategory" CssClass="lst" ValidationGroup="Property" AutoPostBack="true" onselectedindexchanged="CCategory_SelectedIndexChanged" /><span class="hint">Please choose a city where you want to or having a property.<span class="hint-pointer"> </span></span></dd>........
This is not a big issue since it's quite easy to bypass by making a new project and copying everything on it, but it bothers me quite a bit that I can't figure out what it is about. In short my calendar and calendar extenders stop working suddenly. The last time this happened I made some changes to the pages code behind, then hit undo gazillion times to go back to the last save. After that I hit debug and lo and behold: calendar did not respond to any clicks and any text field with calendar extender did not show calendar on clicking them.
This happens in both IE8 and FireFox 3.6 and no amount or restart, rebuild and other such tricks do nothing. The only thing that I can figure out to solve the problem is either use a backup copy of a version that works or make a new project and then copy all the files from the not working into the new/earlier version and all works again. I was able to track down that this seems to relate somehow to AJAX as when I ran the debug I mention above, I got error messages on the web page saying something about AJAX. This however happened only once and I cant get it to happen again (and thus can not remember much about what it said).
Also when I debugged the event handling the calendar click, I get an error message like this: There is no source code available for the current location Then it opens a file search window trying to find some cs file inside the ajax control toolkit. However this only happened the first time I tried debugging the event and I can't remember more details about it. Now I just get that error message when debug exits the event.
So end analysis on my part: The ajax control tool kit gets knotted up all of a sudden for some mysterious reason and is tied to that particular project. Can anyone tell me what this could be about?
