AJAX :: Sys.invalidoperationexception: Ctl00_ContentPlaceHolder1_tc1 Component Was Not Found?
Jul 2, 2010
Rather strange behavior.I have a web application, which has a aspx page which comrises of master page, user controls, ajax tab control & infragistics grid.This page is opening fine from many clients But this page is not opening on one specific client browser and gives sys.invalidoperationexception: ctl00_ContentPlaceHolder1_tc1 component was not found., with XP & IE 6. Please note that, other client browsers with this configuration in the past never gave this problem. This is the first time in many months I have observed this error.I tried to look for various IE options as well, if it has something to do with scripting setting being enabled/disabled, but could not zero-in on anything specific.Has anyone seen this before and can help me in this regard. Any heads-up on this will be really helpful.
I am running in a critical issue with AJAX Tab Container, Tab Panel. I am using VS 2005 with AJAX extension 1.0 (AjaxControlToolkit.dll 1.0.20229.20821) . Every thing works fine but when my internet is slow it throw the Sys.InvalidOperationException and it is not rendering the Tab Control.Problem i understood is : when Sys.Application.add_init() is executing it is looking for the Owner ID and at that time the owner is absent in the UI as tabcontrol is not yet rendered it still getting the data from the DB. Purposed Solution : After document load if ther owner id is null then re execute the same code (Not a good solution but need to make it work as it is in production server ) however it did not work for me . Please provide me some solution as it is in production. his is the code i am using now but not working .

Using the above solution also did not work , My application is in production ,
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.
have a problem on my application, i am using LightBox javascript that is using prototype.js library, and when i open any pop up that is having script manager it generate this error:Microsoft JScript runtime error: Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once.I know that is because i have scriptmanager on the parent page that opened the pop up and its something relates to prototype.js but i dont know the connection!
I am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.
I'm trying to check if the component already has the event...In my example here, I would like to know if the CollapsiblePanel already has the expandComplete handler before I add the event
I would like to know how can I list for every page (child page) selected the number and id of localize component in the current page. I need this to update resources files, a button will be on the master page and when they click on it, they will go to a page which show up every data in the resource file.
i got a problem.. how i can declare template textbox in a datagrid at code behind? i already make a stored procedure and put the update query inside it.. if i declare the textbox inside code behind(.aspx.vb).. there will be an error.. " there is already a component named "txtitem1"component must have a unique name.."
new to working with ajax and having a issue with the Editor component.I have a large internal website to my company and I have a page that I have added the editor control.I also have a button on the same page. In the Button click event I want to do something with the text from the editor control, like save to SQL.But it says Editor1 is not declared, and it is not intellisense anywhere.I have played with this for two days and not any closer to making it work.
This is my main page in which I have collapsible panel and my phone gridview is contained in it. The Initial page loads up properly and shows the gridview. All the errors happen when I select a gridview row for modal popup edit. I get the following errors one after other after ignoring each one of them. I have been struggling with his for almost a week. Following are the sections of the main page and the code in the gridview ascx control. Main GridView User Control Page.
I changed the default namespace of my solution and assembly name, but i still get an error that there is abiguity between these even though the latter namespace is no where to be found.
System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Open() at _default.commentCount(Int32 ArtID) at ASP.default_aspx.__DataBind__control4(Object sender, EventArgs e)....
I thought I had closed all the connections in my code:
I am using static class to do every job related to Database. In this class Connection Object is static but i am creating command object in the method. I read a form post here [URL] about creating connection object local. If we do like that how can we use Connection pooling? There is an example code below.
I am creating a connection object with pooling (Validate Connection=True; Min Pool Size=10; Max Pool Size=200; Incr Pool Size=10; Decr Pool Size=5;). I am expecting to use connection pool by static connection object (this obje has a connection poll) with dynamicly created commands. Am I wrong? Sometimes i am getting "System.InvalidOperationException: Operation is not valid due to the current state of the object." error. Is it because static connectin object?
Now I use HttpContext.GetLocalResourceObject("~/A.aspx") in A.aspx.cs, and it works fine. But if I use HttpContext.GetLocalResourceObject("~/A.aspx") in B.aspx.cs, it throws an exception:
The resource class for this page was not found. Please check if the resource file exists and try again.
Exception Details: System.InvalidOperationException: The resource class for this page was not found. Please check if the resource file exists and try again.
I want to read the local resources from an external page, and I don't want to read the .resx file myself.
In my case, there're some "data.xml" files(they are in different directories, and have elements like [Code].... and the contents of them will be rendered as html.
But the key names in the data.xml should be localized before rendering (different data.xml contain different keys).
For example, the data.xml has such an element: [Code].... " in the [Code].... folder, then use the [Code].... for each data.xml to retrieve the localized key names. That way Idon't need to read the xml myself. Is it possible?
P.S. This is a post I posted in stackOverflow some days ago. You can also answer it in stackOverflow:
My website (VWD 2008 Express) has been running for some time with no error. Something has become corrupted,I am getting the error message "Error: Sys.InvalidOperationException: The path to the web service has not been set." when attempting to use the default authentication message.Nothing has changed in the script manager specification on the page.
I'm trying to set up a page that will allow users to download files from a shared drive (where the file is actually sent via the page). So far this is what I have.
public partial class TestPage : System.Web.UI.Page { protected DirectoryInfo dir; protected FileInfo[] files; protected void Page_Load(object sender, EventArgs e) { dir = new DirectoryInfo(Server.MapPath(@"\sharedDrivePublic")); files = dir.GetFiles(); } }
The aspx page looks kind of like this:
<% Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name); %> <ul> <% foreach (System.IO.FileInfo f in files) { Response.Write("<li>" + f.FullName + "</li>"); } %> </ul>
When I remove the erroneous parts of the code, the page tells me that the Windows Identity I'm using is my user (which has access to the drive). I don't understand what the problem could be or what it's even complaining about.
I think I've found a bug in the ModalPopupExtender. Here is the details:
Problem
When you use ModalPopupExtender within an UpdatePanel, the controls in the PopupControl (the Panel containing the content needs to be poped up) will be rendered, even though the NamingContainer (or the parent) of the ModalPopupExtender and the PopupControl is set to invisible. This may cause Event Validation error between AsynPostBacks. Cause
The controls in the PopupControl will not be rendered within the UpdatePanel, but at the bottom of the page outside the UpdatePanel. When the NamingContainer of the PopupControl and the ModalPopupExtender is set to invisible, the content outside the UpdatePanel won't be updated and therefore stays on the page.
Code
Default.aspx
[Code]....
Steps to reproduce the problem
Create a simple ASP.NET web application in VS using the code provided aboveRun the app in debug modeClick on button Show 1, and then click the link button Show. The popup panel should show up. Click either OK or Cancel to close out the popup panel.Click on button Show 2. You will see the content in the popup panel is displayed at the bottom of the page. However, the content should be invisible and should not be rendered, or should be removed from the page.Click on button Show 1 again. You will see the familar error message: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument...
Further explaination
This error has nothing to do with the ViewState. When button Show 1 is clicked the second time, the page will try to load data (including ViewState, PostData and Session) into the controls on the page before btn1_Click is called. At this moment, pnl1 is still invisible, so the page will only try to load the data for the controls in pnl2. However, if you check the Request.Form.AllKeys in the watch window, the TextBox txt is part of the PostData. This doesn't match any control in pnl2, and then the exception is thrown.
I have tried many different ways, but none of them worked.
