I've inherited some code that is having a serious problem. On one page, there are several pairs of "Yes"/"No" checkboxes that act like pairs of radio buttons through the use of the ACT MutuallyExclusiveCheckBoxExtender control. They work as expected. However, when I navigate away from the page, I get a "Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method." error in the dynamically-generated ScriptResource.ax...c2d9970 [dynamic] file.
The specific method in the dynamically-generated code is:
var $removeHandler = Sys.UI.DomEvent.removeHandler = function Sys$UI$DomEvent$removeHandler(element, eventName, handler)
The element is set to any of the checkbox controls (I've removed them one-by-one and it happens to ALLof them) and the eventName is "Click". I gather from the code that it's trying to do a removeHandler before the addHandler for the particular element has taken place. True, I don't have any explicit addHandler lines in my code, but I don't any explicit removeHandler lines either. About all I've got in the aspx code is:
[Code] ....
The formatting of the code in this message is a bit weird, but it's basically a simple table with three columns. On each row, there's text in the first column, the checkboxes in the second column and a button in the third. I've searched high and low on the web and nearly every thread I read about his error talks about it in relationship to the use of command buttons in an ACT UpdatePanel.

I have controls which are added at run-time to a PlaceHolder control on the page which is inside an UpdatePanel. The first refresh of the UpdatePanel is fine but subsequent actions create copies of everything on the page. I get two sets of the run-time added controls on the same page. It's not smart enough to realize that the second set replaces the first set. Has anyone else seen this? Runtime added linkbuttons into UpdatePanel ;fullpostbacks instead of asyncpostback.All parameters of UpdatePanel are default. adding controls runtime like this:
Modal not showing up when show is called, also error on loading page. Attaching code below, can anyone help me discover my syntax / logic issues here?
NOTE: Did some research on this before posting, some claimed it can be an issue of where the modal is placed on the page in relation to the update panel I am using. I have tried different placements of the modal extender and I also tried removing the update panel all together in hopes to at least see the modal show, no go...same issue. So with that, the issue shouldnt be around the use of the update panel...

I have an ASP.NET form with several update panels. All works great.I use a timer and have it handle some periodic upates. That works correctly too. However, I appear to get an error when I leave the page open running in the debugger. Specifically the above JScript error 12030.I'm not clear how to find the source but I assume it is because my page has logged out. If I refresh I go back to my login page.So, does this sound like the cause? If so, how to I address this?

I created the accordion control custom dll and added the dll my project reference. After adding the reference in my project, I just the drag and drop accordion control and added accordion panes, after adding the pane and clicked design view I am getting the following error. Even I added the selected index=0 properties also but I am getting same error
"Panes could not be initialized. Details: Pane could not be added to the collection. Details Object does not match target type.
So basically when i open the page i get the error above.

The Scenario: I have an asp.net website where I show a div popup on page load for taking a few user details. When a user inputs the details, or closes the popup, I set up a flag cookie so that the popup is not displayed again for the user. The div is in the MasterPage so that it is displayed no matter on which page a user lands first time. The div contains an UpdatePanel which has all the controls required for taking the details. This whole functionality is working fine.
The Problem: Now this div popup is not showing(by setting display:none) on subsequent postbacks(which I want), but the html markup is still loading with the page unnecessarily adding to the page size. What I would idealy want to do is: Check if flag cookie is set. If no, show the popup, else remove the popup's markup from the page. Now since the div is not a server control, I cannot possibly remove it and the all the controls inside it. So, I thought of removing the UpdatePanel from the page:
protected void Page_Load(object sender, EventArgs e) { if (Request.Cookies["flag"] != null) { if (Page.Controls.Contains(updpnl_contact)) { Page.Controls.Remove(updpnl_contact); updpnl_contact.Dispose(); } } }
But I guess this tends to work with dynamically added controls only, and since the control is added at Design Time, it is not being removed. Is there any way I can achieve this?
I am working on a web application project in which i add a dynamic number of LinkButtons at runtime according to user selection, each link should redirect the user to a specific web page ,but what actually happened is that the last hyperlink is the only one responded! the following code show the declaration :
''''''''Public WithEvents ItemName As LinkButton ''Public Sub AddLinkButtons ''''''''For i = FirstIndex To StopFlag ''''''''ItemName = New LinkButton ''''''''ItemName.Text = Dt.Rows(i).Item(1) ''''''''Me.ContentTD.Controls.Add(ItemName) ''''''''Next ''End Sub ''''''''Private Sub ItemName_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ItemName.Click ''''''''SelectedItemToFind.ItemFlag = 1 ''''''''SelectedItemToFind.SelectedItem = sender.Text ''''''''Response.Redirect("Default.aspx?Main=SearchResult") ''''''''End Sub
I have a control that handles commenting. In this control, I have set a delegate event handler for sending an email.
I then have various types of controls, e.g. blog, articles etc, each of which may or may not have the commenting control added (which is done dynamically with me not knowing the id's), i.e. the commenting control is added outside this control. Each of these controls handles it's emailing differently(hence the event).
What I'm trying to determine, is how to assign the event in the parent control. At the moment, I'm having to recursively search through all the controls on the page until I find the comment control, and set it that way. Example below explains:
COMMENTING CONTROL
public delegate void Commenting_OnSendEmail(); public partial class Commenting : UserControl { public Commenting_OnSendEmail OnComment_SendEmail(); private void Page_Load(object sender, EventArgs e) { if(OnComment_SendEmail != null) { OnComment_SendEmail(); } } }
PARENT CONTROL
public partial class Blog : UserControl { private void Page_Load(object sender, EventArgs e) { Commenting comControl = (Commenting)this.FindControl<Commenting>(this); if(comControl != null) { comCtrol.OnComment_SendEmail += new Commenting_OnSendMail(Blog_Comment_OnSendEmail); } } }
EDIT:
The reason I ask is that if I search from this.Page as the initial control, I am worried about time taken to search down the control tree to find it. Each different type of page would be different in how many control it would have. On some testing, it returns back quite quickly the result.
I am building a web site with visual web developer 2010
I have a class (autoButton) that adds a button to a panel (on Default.aspx) and a handler w/i the same class (classifyEventHandler)
The button appears fine, but when clicked the even doesnt fire, what am I doing wrong?
I tried locating the event handler in default.aspx, but it was not found :P
Imports Microsoft.VisualBasic Public Class autoButton Public Sub makeClassifyButton(ByVal theCell As Object) Dim myButton As New Button myButton.Text = "classify" myButton.ID = "b_classify_" + theCell.ID AddHandler myButton.Click, AddressOf classifyEventHandler theCell.Controls.Add(myButton) End Sub Private Sub classifyEventHandler(ByVal sender As Object, ByVal e As EventArgs) MsgBox("done?!") End Sub End Class
I used the following function in my ASP.Net Project (which contains ajax controls)
[Code]....
Microsoft JScript runtime error: 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.
I searched online for solution and got to know its the problem of asp.net ajax. None of solutions (that I found like Add EnableViewState=false, etc.) worked for me.
To demonstrate my issue in ver simple. I have a button in Ajax updatepanel section. When i try to call the script from button click event i am getting the following error.
[Code]....

My error code is..

I have have two radio button lists that need to be mutally exculisve, i.e when one is clicked the other one neesd to be cleared, my further problem is beause they are in a formview I had to add handlers to clear all the controls in the other list when the one is clicked and vice versa. here is the code below Now the code works but one of the testers found that if you click back and forth around twenty times you get the above java error:
Exception message: Maximum request length exceeded
my though here is the handler is being added to many times ? but even if I remove the handler after the process is complete I still get the same error.
I have a Web Form that uses Master Pages. I only tell you this part so you understand the layers.
On the page, I have a web user control. I can see public methods on that user control by simply calling userControlName.PublicMethod();
However, there is a button on this page which generates additional content. This content is based on a placeholder control and adding additional web user controls :
[Code]....
Now, on the main form, I want a submit button that will call a public method of each "subForm" that was added at runtime.
I have tried various forms of Control C = This.Page.Master.FindControl("cpBody").Findcontrol("ctl01")... etc, but can never seen to get the right combination.
I have created an AJAX Server Control Extender which uses the Sys.Timer-object in the client behavior. It worked at first, but suddenly I started to get "Microsoft JScript runtime error: Object expected" when running the page with the extender. When debugging, I see that the line - this._timer = new Sys.Timer(); - in my .js-file which fires the error is the bold line in this function:
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
when I run my site that used Slideshow Extender, i get this Error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Can't add a handler for the error event using this method. Please set the window.onerror property instead.
in localhost i ignore this Error and Slideshow Extender works correct.
but when i publish the site I have JScript Error and Slideshow Extender not be loaded.
