View 3 Repliesim very new to ASP.NET and web based applications. I am very interested in building websites though. a friend told me " if you want to build web sites then forget ASP.NET as that is for applications, stick with HTML" .... but HTML is static code and ASP. NET is dynamic and surely better? the oinly one real thing that gets me though is this "if ASP.NET is used to build Web-forms and web based applications then what good is it for building web sites? ... a web based application and web site/ page are 2 different things? so if i want to get into building web sites for me and other people, what should i need to know? HTML, PHP ect?
View 6 RepliesIs it possible (using HTML5 Shiv, for example) to implement HTML5 on a Webforms-based platform? Will ASP.NET Webforms allow the developer to semantically mark up a page using the new HTML5 elements?
View 3 RepliesI am running into the problem described in http://support.microsoft.com/kb/962351/.The problem is that pop-out menus are not displayed in IE8 Standards mode (they show up as blank).There is a hotfix available.

View 3 Repliesthe account we use to copy/publish websites to our web server is not allowing us access to push websites. I've added this account to the permissions in the links listed in the below link, but i don't have success when trying to push remotely. When the account is in the local admins account, everything works flawlessly, but we are not allowed to have it in there. http://social.msdn.microsoft.com/Forums/en-US/vssetup/thread/31be047e-4716-4974-b8a1-be0111b50199 I've googled and searched a lot for this particular error, but am not finding an answer that helps.

View 3 RepliesI've been searching google for recommendations on conventions or best practices when it comes to the 'case' and naming of files on folders within a Web Application.Most of the time I work within Visual Studio, developing ASP.NET web applications. In the past I've always used PascalCase for all of my files and folders, with the exception of Javascript files which tended to be camelCase.More recently
View 2 RepliesI have been doing dynamic PDF creation via ASP.net for some time -- in the form of HTML to PDF conversion. It works well for us, but we have accessibility requirements from the State to make everything is accessible. For static PDFs, we simply "tag" the files manually using Adobe's accessibility tools. Of course this does not work for dynamically created files. PDFs that I create dynamically fail the Acrobat Pro Accessibility test.
want to create PDFs dynamically in ASP.net, but producing PDFs that are tagged and can pass the Adobe Accessiblity test? I have researched many components, but none that I have found support tagging.

View 4 RepliesI have a page that i created a few weeks back.. had a few controls on the page.. everything worked and works great. Now this past week we had to me some changes to the page, adding a few more controls to the page.. the issue is that now, all the new controls.. (standard .net controls within VS2008) are not accessible from the code behind..
Example, if i add a textbox today to the page.. when i go to the code behind and begin to type textbox1. intellesense doesnt do anything.. and if i complete the line i get a wavy line under it..
In order to gain access to the textbox i have to add this to the code behind
protected Textbox textbox1;

So - to start with textbox1.text is set to 1. But - If I do a postback, the value of textbox is lost - it's just empty. I need to pick up the value of the textbox during "DoThis()" but it only works the first time round.
Surely the value of the textbox is accessible during Page_Iniit?
I'm doing somehting stupid here.
(And BTW - I have to call DoThis from page_Init as that method also adds other controls to the page but I need to get this code working first)/

I have a web page that I am converting from classic ASP to ASP.Net. There are a bunch of "Select" controls (DropDown Boxes) that I am changing to DropDownList controls. I have set the "runat='server'" in all of these controls. However, when I go to the code-behind, they are not visible/accessible. I have tried to "clean" the solution and rebuild it and the controls still won't show.

I have an application that runs on a client's server built on a SQL Server 2005 database.We have now developed an ASP.NET v2 application which connects to this database. This web application will be hosted on an ISP's server but needs to access the SQL Server database on the client's server.
The client's server has a firewall and so forth so I assume it should be possible to make the SQL Server accessible via the Internet but of course I am woriied about security. Can someone point me to some best practices to achieve this.

I am using telerik controls in my c# asp.net project. I am trying to disable a div in a telerik navigation menu from the .cs file. For example:
if (Emp_Role == "1" || Emp_Role == "5")
{
DivLeave.Visible = true;
}
I try run the project I get this error:
CS0103: The name 'DivLeave' does not exist in the current context
Here is an example of the aspx code
<telerik:RadMenu runat="server" ID="RadMenu1" Skin="Sitefinity" OnClientItemOpened="itemOpened"
Width="670px" Height="26px" EnableShadows="true">
<Items>
<telerik:RadMenuItem Text="Expenses" PostBack="false">
<Items>
<telerik:RadMenuItem CssClass="Stores" Width="640px">
ItemTemplate>
<div id="DivLeave" class="Wrapper">
<h3>

If I place the div outside the telerik control it works fine.

There is content page where I have grid, when I click on it, I am displaying modal popup. Everything works fine. The only problem is: I have close button on top of the modal popup window. If modal displays on top of the image, and if I click on close button, then close button event will not fire, insted it redirect to google.com. All other controls besides image are not accessible. If image is not behind of modal (if I scroll down the page), then close button event works fine.
