UpdatePanel AsynchPostBackTrigger Can't Find Control In A Different ContentPlaceHolder
Jul 4, 2010
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 am adding controls dynamically to PlaceHolder which within ContentPlaceHolder
var t = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
var t1 = (PlaceHolder)mpContentPlaceHolder.FindControl("PlaceHolderName");
var t2 = (DropDownList)t1.FindControl("ControlID");
It looks like I am missing something because t2 is always null

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
[Code]....
somewhere in code, but without luck so far.

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've created very simple web site for the test purpouses. Only one master page and one content page.
My content page looks like this:
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<div id="TestDiv1">bla bla</div>
<div id="TestDiv2">ble ble</div>
</asp:Content>
Now, basing on some condition I would like to show/hide a given div. So I am trying to reach one of those divs by Controls collection, like this:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
ContentPlaceHolder myContent = (ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolder1");
myContent.FindControl("TestDiv1").Visible = false; //this is not working
}
}
}
}
But the above example is not working. None of the two div control exists in the myContent.Controls collection. If I place for example a TextBox on my content page, I can reach it through Controls.
So what should I do to be able to access the div control?

In the master page code behind I added
public ContentPlaceHolder BodyPlaceHolder
{
get { return ContentPlaceHolder1; }
}
and now, in web content form I want to add to this place holder a new ascx control in code behind.
protected void Page_Load(object sender, EventArgs e)
{
if (!User.Identity.IsAuthenticated)
{
LoginRegisterControl lrControl = new LoginRegisterControl();
Master.BodyPlaceHolder.Controls.Add(lrControl);
}
else
{
UserProfile upControl = new UserProfile();
Master.BodyPlaceHolder.Controls.Add(new Button());
}
}
and this doesn't work. If I change this to
Master.BodyPlaceHolder.Controls.Add(new Button());
It works. So the problem is with the ascx user control.

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"
