I have a label that is associated with a css class "applycolor", which is applied the first time it is displayed on a page.
[Code]....
defined in css,
label.applycolor {
width: 200px;
color: red;
}
Based upon the selection of a radio button, i would like to change its color back to normal. I tried to use
lblHomeAdd.Style.Remove("applycolor"); but this did not give me a solution.

And after creating string collection i have to create one datarow from it, and had to fill items from string collection. and after that have to add row in table. but when i try with followoing code. it gives me error. because ItemArray=15 and csvdata1.length=16 due to this it gives me error index out of bound exception.
DataRow dr = csvDataTable.NewRow();
for (int j = 0; j < csvData.Length - 1; j++)
{
//fill them
dr.ItemArray = csvdata1;
}
csvDataTable.Rows.Add(dr);
csvDataTable.AcceptChanges();
for this i have tried to create one another string[.
for (int i = 0; i < csvData.Length; i++)
{
csvdata1[i] = csvData[i];
}
how can i remove last element of the string[].
I am using the following code to create calendar controls on textboxes that have been dynamically created using cloneNode. The problem is that in IE it seems to add the behavior twice to the textbox causing it not to work. Is there a way that I can remove this behavior before it is added in ie only to prevent it from being added again? This works perfectly in firefox
var rawDateControlID = ctrlPrefix + 'txtStartDate' + tblPatientMedicationsRowCount;
var $tstCalendar = $("#" + rawDateControlID);
$create(AjaxControlToolkit.CalendarBehavior, { "id": $tstCalendar.attr("id") + "cld" }, null, null, $get($tstCalendar.attr("id")));
In the aspx page I have div with id="progressBar" and runat="server".I need to add width of the div from code behind in C#.
View 3 RepliesI have a <div> element in a web page. I've assigned it an "ID" and made it a server-side control by using "runat=server". How do I define that <div> in the code-behind. I'm been looking at the "System.Web.UI.HtmlControls" namespace and not sure what to use. The reason I need to do this is because within this <div> is a "Submit" button which will cause a postback. When I click the submit button the first thing it does is it executes a procedure to perform edit checks on the various textbox controls. If a control is empty, a message pops up. When the user clicks "Ok" for the message, the <div> disappears because when the form loads, the <div> style.display property is set to "none" by default. Basically, all I want is for the <div> not to disappear when the edit checks are performed and a messagebox pops up.
View 7 RepliesI just wrote this into my WebForms .aspx:
<span id="GenerateChartButton" runat="server"></span>
I went to the code-behind, and typed this:
this.GenerateChartButton
and it's not recognising that I added the span to the page. Is there something I need to do to make this happen? I have been working in MVC lately, so I haven't had to worry about the relationship between the page & code-behind in a while, but I can't remember any tricks that I had to perform to reference a HTML element in my code.
I have a JQuery (using JQuery 1.4.2) problem that exhibits only in IE8 in standards mode, on one specific DOM element but not on other nearly identical dom ellements. The best example of why it makes no sense is below:
$('span.error:visible')[0].style.display
The above piece of code returns "none" which unless i am having some sort of brain aneurism is impossible without there being a bug in either JQuery or IE8. This only occurs in IE8 in standards mode, not in any other browser or on IE8 compatiblity mode. The span that it finds is actually an ASP.net validation control so i only have a limited amount if control over what it renders to the browser. When i inspect the DOM using IE8 developer toolbar and copy the HTML from the DOM it gives me the below:
<SPAN style="DISPLAY: none; COLOR: red"
id=ctl00_cphContentBody_mnMainMiddleNames_ebvMiddleName1 class=error
controltovalidate="ctl00_cphContentBody_mnMainMiddleNames_txtMiddleName0"
errormessage="JQuery should not find this" display="Dynamic" validationGroup="MiddleNames"
isvalid="true" validationexpression="[A-Za-z][A-Za-z '-]*[A-Za-z]*">JQuery should not
find this</SPAN>
If i just do a view source and copy and paste it i get the below:
<span id="ctl00_cphContentBody_mnMainMiddleNames_ebvMiddleName1" class="error"
style="color:Red;display:none;">JQuery should not find this</span>
If i create a simple HTML file containing just either of the above pices of HTML then $('span.error:visible') does not find the spans and i am unable to post code to be able to reproduce this problem. But in the actual asp.net page if i run $('span.error:visible')[0].style.display it returns "none" and if i run $('span.error:visible').text() it returns "JQuery should not
find this".
tl;dr How can $('span.error:visible')[0].style.display return "none".
Edit to answer Nicks comment.
$('span.error:visible')[0].offsetWidth returns 3
$('span.error:visible')[0].offsetHeight returns 22
Which is puzzling, i found the below on the Jquery site.
In jQuery 1.3.2 an element is visible
if its browser-reported offsetWidth or
offsetHeight is greater than 0.
THe element isn't visible, but acording to the above JQuery thinks it is. What does this change mean? It means that if your element's CSS display is "none", or any of its parent/ancestor element's display is "none", or if the element's width is 0 and the element's height is 0 then an element will be reported as hidden. So is the above just wrong. Display is "none" but offsetWidth and offsetHeight are not zero
I'm trying to set a value for an HTML Element within my code-behind. I need to set a <div> elements "display" property to "inline". The way I have it coded is like this:
Code:
divContact.Style("display") = "inline"
Is this the right syntax? I only ask because it doesn't seem to work but I don't get a run-time error when the statement is executes. ???
I've been hired to clean up a website that was written by another company. One of the main issues they have is that the navigation menu doesn't always match the content. On closer look, they didn't use a navigation control or an accordion, but made their own user control out of HTML UL's and LI's (see below). Each section is supposed to expand when you click on it to offer sub menus. Any how, I am trying to find a way when the content pages load to force the menu to focus on the correct UL. Any thoughts on how to do this? By the way they wrote this stuff in 2.0, which I guess maybe why they didn't use the Accordion from the AJAX Toolkit.
HTML Code:
<div class="left-menu">
<div class="arrowlistmenu">
<h3 id="H3mymessage" class="menuheader expandable" onclick="RedirectBrowser(1)">
My Messages
</h3>
[Code] ....
Redirect Browser is defined on the master page:
HTML Code:
<script type="text/javascript">
function RedirectBrowser(ID) {
if (ID == 1)
window.location="MyMessageList.aspx?MessageFolderID=-1";
else if (ID == 2)
[Code] ....
Here is an example of how it is messed up. My Messages should be highlighted but My Profile is.
I was able to acces an HTML element from my c# code this way:
Page.Request.Form["Name"].ToString(), where name was an html element:
<input id="Name" style="z-index: 102;" type="file">
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?
I got a asp: label (hidden by css) to which I store something.
I could not use a hiddenfield since you cannot set a css class on it. I need a css class so I can select it in jQuery. I cannot select by Id since asp.net webforms change your id. I cannot use xxxxx.ClientId, since my jQuery script isn't on that form (oh oh, i miss my mvc)
Anyhow, I pop up a dialog, let the user type sth in. When the dialog closes, I set that label to whatever the use typed in the dialog. That work (I'm testing for now using some alerts) but when I add a button, and in it's click event check the value of taht label, it is still what it originally have been though.
Here is the content of my usercontrol (at run time add as many as needed of them to my view):
Code:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DisputeEntry.ascx.cs" Inherits="TimeSheetDispute.DisputeEntry" %>
<p class="field switch">
<asp:label runat="server" class="disputeReason" ID="disputeReason"></asp:label>
[Code] ....
And in my page, the code that deal with it:
Code:
// Brings up a jQuery UI Dialog containing a textarea to which the user can enter a dispute
// Upon close, place that reason in the hidden input we keep for each date.
function GetDisputeReason(parent) {
var disputeReasonElement = $('.disputeReason', parent);
var existingDispute = disputeReasonElement.val();
var win = $('<div><p>Enter your reason for dispute:</p></div>');
var userInput = $('<textarea style="width:100%">' + existingDispute + '
Here is the contents of my test.ascx file:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="test.ascx.cs" Inherits="UserControls_test" %>
<p id="XXX">aaa</p>
and here is the contents of my test.ascx.cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class UserControls_test : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
this.XXX.InnerHtml = "BBB";
}
}
I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?
I am generating my service code by reading wsdl and client proxy as well using wsdl.exe.
I did it successfully but when I create request object and try to verify with schema it gives me error root element is not found.
I use same schema which I have used in my wsdl document and using xsd.exe I generate my objects.
I found There is XmlRootElement is absent when I mention it no my parent type it works fine.
Problem is Why it's not generating when I used wsdl.exe to generate code.

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.

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 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.

if I have a bunch of HTML code in my variable
is there some function that could remove all the HTML and output only the "clean" text?
For example

I hate it. It's not clear and not validate. When I working with PHP or ASP, I can get a pure HTML page. But can't with ASP.NET.
