Why? What is wrong with it?

You're not going to get your code written for you. You should post the code you have already written and identify which parts you are having problems with. Then maybe someone will be able to give you some advice.

Using cookies to control who is logged in, is insane. Users can edit cookies. Use the Session to store this, and your pages will log out correctly, even if they hit the back button.

Wow - you're using classic ASP ? What a nightmare.

ASP.NET 1:

Response.ExpiresAbsolute = DateTime.Now.AddDays(-1)
Response.CacheControl = "no-cache";
Response.Expires = -500;

ASP.NET 2:

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddDays(-1)); //or a date much earlier than current time

Cookies without a webserver

I'm working on a clientside app that will use javascript on html pages that are stored in the users local my docs folder. This page is then displayed on the users active desktop. The active desktop refreshes at a set time which is great for my app but I need it to remember some setting each time it refreshes. Cookies is what I thought would be a great idea but I don't think I can use them without a webserver. Any ideas?

Hi,

I have the following div element:

<div id="categoryleft" runat="server">LEFT</div>
<div id="categoryright" runat="server">RIGHT</div>

I looking to reference categoryleft at runtime because I want to populate it with categories. How do I do this?

In the code behind ? You can't. You have to put a server control inside there, for example, a placeholder or a literal.

Re: Retrieving an HTML Control at Runtime

If the DIV tag is set to run server-side, it can be referenced in the code-behind as an instance of a HtmlGenericControl class. I'm not sure how the OP intends to populate it though.

I am using ASP.NET 2.0. I have a panel control on my page and I want to add a div to it at runtime. How do I do this. I also want to set the class property of the div at runtime accordingly.

Put a literal inside the panel, and then set it to be the div, with the class property, in your code behind.

Friends,

My cookies value gets reset between every two or three redirect between pages. The cookie value does not reset in mozilla or some version of IEs.
So the problem is not with the code. I have checked everything in IE options also . Wat might be the problem?

a row? What is that? Table row?

If you want to add the row to the HTML table, you can use Javascript to do that. Please check the link below.

hi,

I am trying to use AJAX for my two dropdown lists for my project using ASP.NET. On selecting an item in one dropdown(say dropdown1), the items for other dropdown(say dropdown2) should populate. Dropdown1 items are retrived from database using C#. My question is I need the selected item value of dropdown1. If I use dropdown1.SelectedItem.Value in C# side means error occurs. I need the selected item value.How can I get it using either javascript or C#.

Just now I am populating all the items in dropdown2. But I need the selected item value of dropdown1, so that I can able to filter and populate items in dropdown2 corresponding to dropdown1 item.

Can anyone help me. Please..........

Why don't you make a search "javascript get selected item of dropdown[^]" in Google first? Smile | :)

this.options[this.selectedIndex].text<br />
this.options[this.selectedIndex].value

Ref: http://www.velocityreviews.com/forums/t120967-dropdownlist-selecteditem-javascript.html[^]

var dropdownIndex = document.getElementById('colorsselect').selectedIndex;<br />
var dropdownValue = document.getElementById('colorsselect')[dropdownIndex].value;<br />
document.write(dropdownValue);

Ref: http://blog.techsaints.com/2007/05/06/javascript-how-to-get-selected-item-in-dropdown-select-list/[^]

Actually, both examples are the same.

Thanks. I have searched in Google first and also posted here. Its working fine.
I found that to get the value we can also use

document.getElementById('<%=ddlTraining.ClientID%>').value;

Its also returning the selected item value.

Thanks for ur help and I need it.

Hi all, I am developing one application. In that i have created on report file which contains tables, titles and tree view list also by using HTML tags. I am opening this file in my application it self as another window.
There is no problem in opening this file if the file is small. If the file is big(here i mean to say, if number of tables present in this file are more)then while opening this file my application is displaying a message "Cannot create unique tag, giving up" (This message is given by HTML script i think) . I am unable to understand this message.
Can any one please tell me how to avoid this ???
