C# - Could Not Find UpdatePanel With ID Exception While Using UpdatePanel
Mar 1, 2011
On an aspx page i am having a dropdownlist and a panel control the dropdownlist autopostback is true. in dropdownlist control there are two options and depending on the option selected by the user i display a user control containing ajax updatepanel with a timer configured to launch async request after every one second. the problem arises when user selects the other option in dropdownlist control and the user control gets changed in the panel control. The error which is occured is shown below:
Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_cphMainMasterPage_ChildContent_ctrlPinStatusMonitor_updpnlPinStatus'. If it is being updated dynamically then it must be inside another UpdatePanel.
I thnk the problem is that the last control which have launched the async request is no more available in the panel control and gets replaced by the new other user control.

I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?
Complete code is below:

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:

I'm using a Master Page with two content areas to render a two-column format.In the left column (Content ID="Left") I have an UpdatePanel (ID="ChoosePanel") with a TreeView control whose ID is "StickTree".In the right column (Content ID="Right") I have another UpdatePanel (ID="ChartPanel") with UpdateMode="Conditional" and the following trigger:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="StickTree" EventName="SelectedNodeChanged" />
</Triggers>
There should be no problem having the trigger in a different UpdatePanel, but I'm getting the following exception when I run the page:A control with ID 'StickTree' could not be found for the trigger in UpdatePanel 'ChartPanel'.

I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

I've got a page with two ContentPlaceHolders. In first there is UpdatePanel with GridView. In second I located DropDownList which is trigger for UpdatePanel.
<asp:UpdatePanel ID="stanUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" >
<ContentTemplate>
GridView & other stuff
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ATDropDownList"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
Running the page causes error: "Control with ID 'ATDropDownList" could not be found for the trigger in UpdatePanel". I thought it was because the ATDropDownList is located inside ContentPlaceHolder. So I changed ATDropDownList's ID to UniqueID as follow:
<asp:AsyncPostBackTrigger ControlID="ctl00$ContentPlaceHolder2$ATDropDownList" (...)>
Everything works good, but I want to change it from page's code-behind. I tried to put

somewhere in code, but without luck so far.

I have three UpdatePanels on my ascx page. In first I have gridview, in second I have DetailView. DetailsView is in a Panel, after click on buttom -Panel show or hide. All works fine. I added third Panel, new Buttom , inside Panel I put UpdatePanel and I would like the some function as in DetailView - show or hide Panel.After click on buttom I can see this error-Sys.InvalidOperationException: Could not find UpdatePanel with ID 'xxxxxxxxxxx. If it is being updated dynamically then it must be inside another UpdatePanel.
I tried many examples, whitch I found on the internet (move Buttom on page - change its position, add UpdateMode="Conditional" to the UpdatePanel), but without any resolution.
My code
<asp:Panel ID="Panel6" runat="server" CssClass="myCssClass">
<div>
<asp:Button ID="Button1" runat="server"

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 a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup. Initially the gridview merely displayed saved records you personally choseto save, well when you selected one, the popup would close and the data from that row would be passed to the gridview within the page to display details.. no issue when it was setup that way.. well eventually it was decided to add a delete option within themodal popup gridview so now when viewing the records you can delete it if not needed. works well.. but now with the updatepanel surrounding the gridview when i click on my "select" link it doesnt execute my

I have TextBox (multiline) and Label in an UpdatePanel which I refresh with javascript __doPostBack(upEditReminder,id);
Then I set both Label and TextBox text to current DateTime.
protected void upReminder_Onload(object sender, EventArgs e)
{
lbTest.Text = DateTime.Now.ToString();
tbReminder.Text = DateTime.Now.ToString();
Problem is that Label is updated but TextBox date is updated only once when the page is loaded but not when __doPostBack(upEditReminder,id); is triggered. I cant figure out what the problem is.
I have also tried textarea runat="server" but still have the same problem.

I have two updatepanels inside an accordion control, laid out like this:
<accordion>
<first pane content>
<updatepanel UpdateMode="conditional">
<contenttemplate>...</contenttemplate>
<triggers>...</triggers>
</updatepanel>
</first pane content>
<second pane content>
<updatepanel>
<contenttemplate>...</contenttemplate>
<triggers>...</triggers>
</updatepanel>
</second pane content>
</accordion>
The panel updates once, but after that, no updates take place. If I refresh the page, then I can see the updated information. This means that the database is being updated, but the updatepanel isn't refreshing (after refreshing the first time). Why is this happening?
update
The problem seems to lie when I call this:
Sys.require(Sys.components.accordion, function() {
$("#acca_profile").accordion({
HeaderCssClass: "acc_header",
HeaderSelectedCssClass: "acc_selectedheader",
FadeTransitions: true,
suppressHeaderPostbacks: true,
requireOpenedPane: false
});
});
in the endRequestHandler function. However, if I don't call it, then the div that should be converted to an accordion is no longer an accordion.
Update 2
After a bit more work, I figured the problem may lie in the fact that the Jquery is not rebinding the events after the partial postback. A lot of solutions claim that you have to register the client script, but I have this at the top of my aspx page:
<asp:ScriptManager runat="server" EnablePageMethods="true">
<Scripts>
... (other script)
Path="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
</Scripts>
</asp:ScriptManager>
How can I rebind the JQuery events in my code?

I have a child page with an UpdatePanel on it that is connected to a timer that autorefreshes every 5 seconds. I've tried a few different PNG fixes, and they work until the UpdatePanel refreshes that section. Then, depending on the fix the PNGs either disappear or go back to nontransparent. Do I need to forcefully run the javascript when the UpdatePanel refreshes? How would I go about this?
