What does that means below warning:
Element 'AsyncPostBackTrigger' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
My app is working properly but visual studio showing warning like that.
I have noticed that when I create a website in a network drive and use the Ajax toolkit I get :
Element 'ToolkitScriptManager' is not a known element
I also noticed that after adding the ToolkitScriptManager it doesn't add the ID in the source code, it looks like this:
<asp:ToolkitScriptManager runat="server"></asp:ToolkisScriptManager>
Is missing the ID="ToolkitScriptManager1" part.
This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.
I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.
View 6 RepliesI'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.
I was wondering, what is the difference between assemblies/references added in either location?
Is there a way to retrieve values from the form object using the id element instead of the name element?
View 3 RepliesI have a table in ASP.Net like this.
[code]....
I want to give border line to first td element which contains the colspan and rowspan. Not to the entire row.
I would like to select an element that is in the same TR as another element I found with a selector. The selector itself: $("input[name='sMessageValue']","#messageTable") Now I have this element and got its value I would like to find a checkbox located in the same TR, i tried this as starting point : $(this).(':parent').val(). But seems not the right thing to do.
View 9 RepliesYou're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/default.aspx" title="Home" description="">

Element 'content' is not a known element. this can occur if there is a compilation error in the website, or the web.config file is missing.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Content --- showed a green wavy line , and on hover displayed the above error.
Now I am having certain problems.
1. Visual Studio 2010 hangs when I try to use ToolBox.
2. Intellisense for asp.net controls is not working.
I have tried replacing web.config file (frm backup) , tried to debug - it doesnt show anything.
All other websites are working alright. Have problem with only one of the websites.
I got this errors while trying to use an example from the ASP.NET 3.5 Unleashed book.
Webform1.aspx
[Code]....
LengthValidator.cs
[Code]....
As from the book's note, I think I added this line correctly:
[Code]....
However, the compiler kept complaining that:

I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll.
web.config:
<add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/>
The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts.
Each page has a reference to the assembly:
<%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %>
Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.

So I have a file called WebParts.aspx which looks like this -
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebParts.aspx.cs" Inherits="e.WebParts" %>

I converted a forms website into an application and everything has been working just fine until now. I keep getting the green squiggly lines and the error that Element 'X' is not a known element. This is on almost every element, Gridview, Label, Update Panel, Hyperlink Field, Bound Field, etc...
my web.config contains
<pages theme="basic">
<controls>
<add tagPrefix="ajax" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit"/>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</controls>
</pages>
so ajax and asp are viable prefixes. The very odd thing is that it is only happening on a few user controls, all other user controls are fine and the errors never show up. I have tried rebooting and everything and nothing seems to fix it. All masterpages, web paages, and about 90% of the user controls are fine, its only on a few user controls and super annoying!
I would like to write some html content to div element through web method. The web method should be like
[System.Web.Services.WebMethod]
[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
public static string LoadImages1()
{
[Code]....
without passing data to success block, I have to write at webmethod it self.
Is there a quick way to get the instance by Dom element.
My way is:
Base.find = function(element)
{
var c = Sys.Application.getComponents();
for (var i = 0; i < c.length; i++)
{
var e = c[i].get_element();
if (e == element)
return c[i];
}
return null;
}
I have an animation that hides the calling button and then shows a panel with text related to the button. The text panel needs to be "display:none" in my CSS because it and the button are part of a control overlay in a seadragon control (don't want it to stop the deep zoom).
When I run the animation, the button fades out, but the text panel does not appear. When I watch the panel's style, the opacity does go to 1, but the display style does not change from none.
I have the following animation block:
[Code]....
And the CSS for the report panel looks like this:
[Code]....
It does fade in if don't use the display style, and instead set the visibility to hidden, but then I can't interact with my deepzoom.
Suddenly all update panels in my website became unknown elements. They work fine when I run site.
But:
no intellisense in update panel (no properties appear, no tags, like "triggers")
no ID property when I drag updatepanel from toolbox
VS says that I check if webconfig contains reference to System.Web.Extensions
But I have this reference already.
I have 2 similar partial views.
View #1:
[Code]....
View #2:
[Code]....
In my Index.aspx view I have 2 Ajax.ActionLinks that load these partial views into a div. The problem is, in the 2nd case the script is not loaded. Here are screenshots from IE8 developer tools (F12):
Screen #1:
Screen #2:
The sample MVC application is here: [URL]. The actual application I'm having this problem with uses jQuery.globalEval() to execute these scripts. Currently I have to insert <div style="display:none"> </div> before the script tag if it happens to be the first one in order to make it work.
I'm trying to find an ajax.net extender element with a dynamically generated ID. I'm trying to wire up an event handler to close all ajax.net modal popups when 'escape' is pressed. I'm confused why one of these works and one does not.
$find('ctl00_MainContent_ucUserControl1_mpePopup'); //returns the element
$find('[id="ctl00_MainContent_ucUserControl1_mpePopup"]'); //returns null
The ultimate goal is to be able to find the element without hard wiring the ID into the selector: $find('[id$="_mpePopup"]'); //return all elements that end with "_mpePopup"
AsyncFileUpload control is rendering in this way.
<span
id="Span1"><input
type="hidden"
name="uploadinput$ctl00"
id="uploadinput_ctl00"
/><div
id="uploadinput_ctl01"
name="uploadinput_ctl01"><input
name="uploadinput$ctl02"
type="file"
id="uploadinput_ctl02"
id="uploadinput_ctl02" onkeydown="return false;"
onkeypress="return false;"
onmousedown="return false;"
style="width:
355px;"
/></div></span>
Is there any way to assign styles(like width, position,top etc..) to Input type=file element alone.One way i can see, is using Jquery document.ready eventhandler,
$(function(){
var element = document.getElementById('<%=uploadinput.ClientID%>').lastChild.firstChild;
element.style.width = '150px';
but the problem with that is, i am not able to identify input type = file element after postback in that document.ready eventhandler.please let me know if there is any other way to assign styles to input file element of AsyncFileUpload control with out any issues.

I'm trying to implement live binding, purely imperatively . In my example , I have a master view , which is populated using json array. In the detail view ,I'm just setting the value of a prepopulated combo box . But , the moment the bind statement is executed, the combobox (select element) becomes null. This works perfectly when done declaratively. Below is the code for imperative binding. This function is triggered when an item in the masterview is selected.
function execCommand(sender, args) {
// Create dataview for details section
var detailsView = $create(Sys.UI.DataView, null, null, null, $get("div2"));
$get("div2").className = "sys-template";
// bind the dataview to the selected data from the master
var b = Sys.bind(detailsView, "data", sender, "selectedData");
// after the above line of code is executed, the select element with id "myselect" becomes null.
//alert($get("myselect"));
// bind the value attribute of the combo box to the "Description" property of the binded data
var x = Sys.bind($get("myselect"), "sys:value", detailsView.get_data(), "Description");
//hence when the above line of code is executed , nothing happens :( ,i.e the value of the combo box doesn't get set
// alert($get("myselect"));
}

I have vs2005 Pro, vs2008 Pro and vs2010 Pro installed on a Vista machine. Recently I upgraded a non-AJAX web site from vs2008 to vs2010. The web site works fine but now I'd like to use the UpdatePanel. However after I insert the ScriptManager I receive
the following error:
"Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing."
All the posts I have read seem that I should not see this error in vs2010. I have even added the following to the web.config with no success:

As a side note, I am able to use the latest AJAX Control Toolkit for .NET 4.
