Environment: .NET 2005,Framework 2.0
I am manipulating a select element(asp:dropdownlist) through javascript-adding and removing elements. I am unable to get the manipulated data during postback. For workaround, I am using a hidden control(some special characters to separate the list) to track the changes. Is there any optimized way of doing this?

System.IO.Directory.CreateDirectory but you will hit permission issues most likely.
But I really think you're going the wrong way with this looking at your earlier post.

The entire problem is
1> An user is going to create an account once he creates it.. Dynamically 4 folders has to be created so tat his own images , templates, ect can be added and will be stored in that folders..
2> Again the user is also having the facility of adding a new page into his account so that he can add features on to that page..

See my answers in the thread below. If you still want to go this way, I'll let somebody else come in - I think you are going to hit a lot of problems allowing end users to create physical pages on the website. What about security? A clever user could inject anything into a page that is 'theirs'.

Looks like you are designing a web hosting system. For images you can have a common pool with some unique name. At runtime you can decode them. For pages, can you check out URLRewriting?
Too many folders would clutter your server file system and maintenance would be a nightmare.

The problem is in an ASP.NET web applcation their is an option called addnew page, so the users will create his own pages in that page . An aspx page should be added to users account dynamically so that he can add his contents in that page.

hi edwin,
thank you,
well my problem is in an asp.net application user has an option of add new page in his account.
So that a new ASPX page has to be added into his account..
Consider an example...
This is basically an ecommerce project .
if their is an user called xyz. he wants to add a new page in his account so that an aspx page should be dynamically added only to his account.And xyz is going to add his own images ,template in that page.
thank you

CMS (Content Management System). In ASP.NET 2.0 U will find it in ToolBox Web Part.
Or other way U can Save every user settings in database.
But I suggest U to use web parts. U can find it at msdn how to use it.
Of course U can use xml.
Regard,
Edwin

Something like a content management system ? You can open existing ASPX files using filestream and write it to the disk with other name. Put some special tags where your content need to be replaced. Replace this special tags with your content when page is creating.
But keep it in mind that this will work if you are using ASP.NET 2.0, in ASP.NET 1.1, code behind data will be wrapped in dll's. So creating a simple aspx file won't do work.
Alternative approach would be using UrlRewriting. In this case, you won't be having files, all the URL's you are seeing will be virtual.

Data for content management like this is usually persisted in some data storage mechanism, like a database or xml file. The file/data describes the page and content, and then a generic pages is used to read this data and build the page on teh fly. Look at iGoogle. Each page for each user is different. But Google don't create a new page for each user, they store the users layout in a DB.

Thank you,,
Will xml and xslt sove this problem .....

Yes. Store the data in Xml, apply an xlst translation to it and, as if by magic, you have a web page.
You need to work on the xml layout to ensure the page is described well. It is not a 30 minute job either, but certainly better than writing a HTML code generator, which is what you would need to do for your original idea.

Be aware of exposing dynamic WebForms to user. Unless you have enough NTFS permissions in place, you are opening up the Pandorra's box on your server.

Hi all,
I have a textarea. I populate the textarea with data from the database and load it into the textarea using <%=stringVariable %>, then the user can change the text and then save it back to the database, but when I try to get the value for the textarea I get the following error:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
One suggestion I have found is to use <%#stringVariable %> instead, but then it doesn't display the text in the textarea.
Does anyone have any suggestions or solutions to solve this problem?
Thanks in advance

Is your textarea a server control ? If yes no need of doing this. Directly in code behind file you can assign value to it.

This is what I have in the content page
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="editor.aspx.cs" Inherits="htmlarea_editor" Title="Untitled Page" ValidateRequest="false" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:LoginView runat="server" ID="loginView1">
<LoggedInTemplate>
<textarea runat="server" id="editorArea" name="htmlEditorArea" rows="40" cols="60">
</textarea>
<asp:Button runat="server" ID="btnSave" Text="Save Changes" OnClick="btnSave_Click" />
<asp:Button runat="server" ID="btnCancel" Text="Cancel Changes" PostBackUrl="~/index.aspx" />
<script type="text/javascript" language="javascript1.2">
var config = new Object();
config.bodyStyle = "background-color:black;color:white";
editor_generate('<%=textAreaName %>',config);
</script>
</LoggedInTemplate>
</asp:LoginView>
</asp:Content>
But in the codebehind I can't access the textarea, when I try to use
editorArea.Value
it doesn't find the control.
I also tried using
((HtmlTextArea)FindControl("editorArea")).Value
But then I get the message that I have to use the new keyword
Any suggestions?
Thanks

How you added the textarea ? From tool box. Here I am not seeing any need of using HTML text area and making it runat server. Instead of this, you can use asp textbox and set multiline true, and you will be able access this from code behind

The thing is I need to use a textarea, the script underneath the textarea is a WYSIWYG editor, and it uses the textarea and the textarea name to change that into the editor, otherwise I would have used a textbox.
