UpdatePanel Conditional Updatemode Not Working
Feb 9, 2011
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 a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders
- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.
The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.
What is causing the partial postback not to render anything?
I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.
Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.

I've got a weird problem: On a page, i've 2 updatepanels in conditional updatemode, with childrenastrigger set to true (default value).
A click on a IPostBackEventHandler control inside either the first or second updatepanel causes the 2 updatepanels to refresh.

I have 2 UpdatePanels in the same Page, and each one contains a GridView with some datta. I am using UpdateMode="conditional" because i only want the GridViews to be Filled when needed. So the data in each GridView is loaded only if the user asks for it, and it's not loaded again unless you need a change in the grid (sorting or page changing).
GridViews are filled with data from a DataBase, but I only read the data from the Database when needed. So, in first Page_Load, any data is readed. If the user wants to see the data in GridView1, the data in GridView2 is not loaded from the database, and viceversa.
My problem comes in this situation:
User enters the Page.
User ask for the data in GridView1 (UpdatePanel1 does the job)
User ask for the data in GridView2 (UpdatePanel2 does the job)
Now, the user can see both gridviews in the page. If he tries to change the page index or to sort data in GridView2, everything goes fine. The problem comes when he tries to change the page (or sort) in GridView1 (because in the callback to retrieve the data to GridView2, GridView1 was not filled, so the data the user is seeing is there because of a previous callback). The user gets an Event Validation Exception, and i don't know how to avoid it. I think it's because the server "thinks" that GridView1 is empty, because of the callback to load data to GridView2, where GridView1 was not filled.

I've got 2 gridviews on a page. One is inside an update panel with update mode set to Conditional
<asp:UpdatePanel ID="UpdatePanel1"
UpdateMode="Conditional"
runat="server">
However, in the 2nd gridView, I'm clicking on a thumbnail image, in order to see a full size image by recalling the page and adding a QueryString e.g. Content.aspx?Image=Pic1
This all works fine.
However, when I am on the 2nd page of records in the first GridView, calling the page from the images in the 2nd gridview causes the 1st gridview to go back to the 1st page of records. Despite being inside a conditional UpdatePane.
(Perhaps theres a way to update the images only, without calling the page again...?)

i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

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).

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 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");
if (btn) {
btn.click();
}
}
}
function loadCalendar() {
__doPostBack('ctl00_contentBody_UPCalendar', '');
}
