I'm trying to programatically add a second class to a <td> element in C#.
The element I want to add the class to already has a class assigned to it.
If I do something like
myObject.CssClass = "MyClass";
it simply overwrites the original class.
I suppose I could do something like
myObject.CssClass += " MyClass";
How to add a class before a given element?
The code doesn't add a class but instead add a new element. [:(]

I have a few scattered <p> elements on the aspx page which I am grouping together using a class like so - <p class="instructions" runat="server">
In my code behind, using C# I want to hide these elements, using something like
instructions.Visible = false;
However I realize I can only do this in codebehind if I use ID but this will result in invalid HTML/CSS Selector since you can't have multiple ID's with the same ID name...
Alternatively is there another way to group the controls if not by class?
EDIT: I can't use JavaScript, so the selection must be done in C# codebehind/ASP.NET
I am trying to auto fill city and state value after user typing 5-digit zip code. The Ajax part works perfectly, the problem is I have two sets of zip/city/state fields in one web page. I searched this issue for quite a while, using next(),nextAll() even slice(), none of them work in my situation.
Web page related part:

After using Ajax function I get returned value for city and state. For each city textbox I give a "city" class, for each state dropdownlist I give a "state" class. I wonder how can I put those value into right position?
To demonstrate that I could even use a Class attribute on an option elem I tried adding class attributes to options of a select elem in a static page and that works fine. I noticed that not many online resouces documented this so I figured I would explicitly set the record.
here is the jquery code attempting to add a class to the selected option

New information, I found the reason nothing occured was a simple mistake in the value being passed in for compLev. However, now it runs through the code for the correct case and does nothing to the color of the item.
I have a VS 2003 Web app that I'm creating. I'm using a Panel control and I'm trying to apply a CSS class to this panel. However, when I try coding the following statement
<asp:Panel class="pnl2" runat="server">
it doesn't like the "class" attribute saying "could not find any attribute 'class' of element panel"? I'm used to using VS 2005 and higher and haven't seen this before. What am I doing wrong?

I'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.

I want to give border line to first td element which contains the colspan and rowspan. Not to the entire row.
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 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 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 got this errors while trying to use an example from the ASP.NET 3.5 Unleashed book.

As from the book's note, I think I added this line correctly:

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" %>
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.
Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.
Element 'UpdatePanel' 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" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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!
Since we can access the private data member of base class in the derived class with the help of friend function. How can we do the same in C# asp.net? I mean whats the alternative of friend function in C# asp.net
View 2 RepliesUsing the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
I first need to apologize in case this has been answered before but I'm a newbie (green as they come) and this error keeps popping up even before I start debugging! There are two errors and the second one is:" Error 2
