CSS ID Selector Not Working But Class Selector Does?

Feb 21 10 at 3:50

I am having a problem in that a style is not being applied when I used an "ID" selector (#btnOK). However, if I use a class selector (.btnOK, by changing the "#btnOK" to a ".btnOK" in the CSS file), the style is applied.

The style IS also applied in design mode, but not at run time. It's findingf the css file, else, the class wouldn't be applied. Case sensitivity match on the ID.

In the web page:

<link href="CSS/CvCost.css" rel="stylesheet" type="text/css" />
<asp:Button ID="btnOK" CssClass="btnOK" runat="server" Text="OK" ValidationGroup="Add"/>

In CSS/CvCost.css:

height: 25px;


Is It Possible To Map A CSS Class Selector To A Tag Selector

Feb 14 at 22:23

More specifically, given a set of style sheets that define a class selector called "content_title", is there a way to apply that style to all <h1> tags without changing each one to <h1 class="content_title">, i.e. to effectively apply that class to all instances of a given element?

The context is that I'm trying to apply HTML and CSS from a graphic designer to existing web applications and some of the selectors don't match up very well.

I have an ASP.NET web forms application that uses master pages and a theme. I've been given an HTML sample/template that that includes several style sheets.

So I updated my master page to use the new design, and now it looks something like this:

<%@ Master Language="VB" AutoEventWireup="false" CodeBehind="MyMaster.master.vb" Inherits="MyApp.MyMaster" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<!-- these are the new style sheet from the graphic designer -->......

My goal is to use the designer's style without having to edit every content page that includes an <h1>.

I could copy the styles from the designer's CSS to the stylsheet in my app's Theme (substituting the class selector for the tag, of course), but then i wouldn't really be using the source CSS and I'd have to do this again the next time the external CSS changes.

I'm also not likely to get the external CSS changed to fit my app.

So is there something clever I can do to make <h1> == class="content_title" with respect to the application of styles, or will I have to bite the bullet and update each and every one of my content pages?

Asp - Visible Selector Not Working In Internet Explorer

Aug 3 10 at 17:52

I'm working on some basic form validation styles for an ASP.Net website. I need to select all span elements that are visible, and add a css style to another element. (Just to indicate which input fields are invalid.) The below code works like a charm in FF and Safari, but fails in IE. I've narrowed the problem down to the :visible selector. Here's the jQuery code. IMPORTANT NOTE: Production site is running jQuery 1.3.1 There were changes made to the :visible selector in 1.3.2 release notes

$('span.inputError:visible').each(function() {

Here's the rendered HTML it's intended for:

<table width="100%" cellspacing="0" cellpadding="3" border="0">
<td valign="top" style="text-align: right;" class="address_labels">
<label><span>*</span> First Name: </label>
<span id="ctl00_CMain_txtFirstName_wrapper"><input type="text" style="width: 190px;" invalidstyle="inputError" class="radEnabledCss Input" name="ctl00_CMain_txtFirstName_text" id="ctl00_CMain_txtFirstName_text" size="20" value=" zdogg"><input type="text" value=" zdogg" style="border: 0pt none ; margin: -18px 0pt 0pt; padding: 0pt; overflow: hidden; visibility: hidden; width: 1px; height: 1px;" name="ctl00$CMain$txtFirstName" id="ctl00_CMain_txtFirstName"><input type="hidden" name="ctl00_CMain_txtFirstName_ClientState" id="ctl00_CMain_txtFirstName_ClientState" autocomplete="off"></span>
<span style="color: Red; display: none;" class="inputError" id="ctl00_CMain_valFirstName">First name is required</span>

JQuery Selector - Finding Img In Table

Mar 8 10 at 8:06

Cant seem to get the following to find the 'skull' button when the 'heart' button is clicked. Here is the JQuery.

$(".voteup").click(function() {
var id = $(this).attr("title");
var userID = $('[id$=HiddenFieldUserID]').val();
var ipAddress = $('[id$=HiddenFieldIPAddress]').val();
var skullButton = $(this).parent().siblings(".votedowntd").children("votedown");
registerUpVote("up", id, $(this), skullButton, userID, ipAddress);
And the HTML...
<table width="200px">
<td width="35px" class="votedowntd">
<img src='<%# (bool)Eval("skull") ? "images/skull.png" : "images/skull-bw.png" %>' alt="Vote Down" class="votedown" title='<%# Eval("entry.ID") %>' />
<td width="130px" style="text-align: center;">
Num Votes Goes Here
<td width="35px" class="voteuptd">
<img src='<%# (bool)Eval("heart") ? "images/heart.png" : "images/heart-bw.png" %>' alt="Vote Up" class="voteup" title='<%# Eval("entry.ID") %>' />

So basically what I need to do is when one img is clicked, I need to find the other one. Why is what I have not working? Is there a better way to do this?

Initialized From A Static .js File Using A Selector?

Mar 23 at 9:15

I'm using jQuery tabs, which are initialized from a static .js file using a selector:

.ready(function () {

I'm using ASP.NET (not that it makes a difference I think), but when I click a button in one of the tabs, is there a way I can re-select that tab when the page reloads. I was thinking of sticking the tab section in an UpdatePanel. I was hoping there's a way I could trigger the tab to reselect.

Is There A Cross-browser Way To Use A JQuery Selector On An Expando Property

Sep 2 10 at 13:58

I have an ASP.NET page and I am trying to quickly match the validation controls that are tied to a particular textbox (text input) using a jQuery selector. The validation controls render as a span and the "controltovalidate" property renders as an expando property. Here is a test example:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript" src="jquery.js"></script>

The problem: the ml_test() function shows 1 in Internet Explorer 7 (as expected), but shows 0 in Firefox 3.6.8. I tried adding additional controls, but in Firefox it consistently doesn't work.

I discovered this post that shows the use of an ampersand in the selector like this [@expando=value], but when I try this syntax, jQuery 1.4.2 throws an error.

Is there a cross-browser way to select expando attributes, and if so, what is the proper syntax?

I want to select this element to track its change event, but i cant directly select its id because asp.net changes its id on runtime.

its id, attributesList changes into ctl00_adminPlaceHolder_attributesList.

so what i want to do is to use a "contains" xpath expression to select the element.

JQuery .find(selector) Troubles When Selecting Ajax.net Element

$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"

Want To Make A Simple "date Selector" With 3 DDL's For Day / Month / Year?

May 29, 2010 04:03 PM

I have never created a user control before. I want to make a simple "date selector" with 3 DDL's for day, month, year, and be able to re-use it numerous times on a page. I don't need to set any values of the control from the page itself, but I do need to read the DDL.selectedValues. I created the DDLs in the ascx file, but am not sure what properties to create. Does it make sense, or is it recommended, to create a public readonly property for each DDL _as_ a DDL? Or do I want to create a public property of type "string" and return the DDL.selectedValue as a string?

Intellisense Class Reference Not Working In MembershipProvider Derived Class File In App_Code F...

May 17, 2009 09:48 PM

I am new to ASP.NET and may be biting off more than I can chew, but I figure if I jump in the deep end I may learn more.why the Visual Studio intellisense is not working in a newly created class file inside the App_Code folder?I presume that System.Web is not being referenced from the App_Code folder correctly for some reason, because as soon as I type "using System.Web", everything is fine and then stops when I want to dd ".Security" (no dropdown). I think this has an influence on the fact that the inherited MembershipProvider in my code is not highlighted/referenced and I cannot use the "Implement Abstract Class" option.

Data Annotation Attributes Not Working Using Buddy Class Metadata In An MVC App?

Oct 7 10 at 14:13

I have found hints that MVC 2 recognises the 'buddy class' type of property metadata, where data annotation attributes are applied to a 'buddy' metadata class, and the MetadataType on the actual entity class points to that buddy class, as below. However, as below, it seems the only attribute that makes any difference to the rendered UI is DisplayName. Why are the other attributes like DataType, Required, and ReadOnly not working? I.e. why can I enter text in a read only field? Why do I not get an error when a required field is empty? Why does the DataType attribute have no apparent effect? Why does EditorForModel not include validation messages?

public partial class Customer
public class CustomerMetadata
public object CustomerId { get; set; }
[Required(AllowEmptyStrings = false, ErrorMessage = "Customer No. is required.")]
public object CustomerNo { get; set; }

I find behaviour the same whether I use an explicit LabelFor and TextBoxFor for each model property, or a single EditorForModel for the whole model.

C# - Webservice Complex Types And Class Inheritance - Use The Properties Of The Base Class?

Mar 13 10 at 0:53

Using the following Webservice definition using aClientArgs as a complex type:

public class Controller : System.Web.Services.WebService {
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/">
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">

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?
