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'm using VS2005 and when i drag and drop an image button, i can't access it from code behind. the following is an example of an unaccessible imagebutton

I 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;
I have a PlannerShiftView user control in the root folder of my ASP.NET web site. In my App_Code folder, I have a ShiftViewTemplate class that needs to instantiate a PlannerShiftView (for a TemplateField in a GridView). The problem is, the following code doesn't compile because the PlannerShiftView type is not available in what I deem to be the App_Code 'phantom namespace'.
Please can somebody explain to be what is happening here, as well as what to do. I know I can just move the ShiftViewTemplate out of App_Code, going against convention and without explantion, but that is something of a hollow victory.

After much research, no solution can be found to do what I want by combining these two controls. Currently, I have a repeater control which, in page_load, takes the querystring and queries the database accordingly, puts the resulst in a datatable, and binds the datatable to the repeater. Everything works fine, no problem there. It's just that I have many columns coming from the query and there are many rows as well. So, I thought it would be easier to incorporate the accordion, so that the header of each accordion pane would show some unique fields (name, whatever...) as the header, and the rest of the many fields in the content. This way, there would be many closed accordion panes showing the name from the row returned. If the pane is clicked, the pane would open and show the rest of the results.
The problems I've had are that the repeater is not accessible from the code behind if it is inside the accordion. But I'm sure I wasn't doing it right anyways. I'm just trying to have an accordion that has as many panes as there are results from a datasource. If there is something other than a repeater that you can suggest, or the correct way to incorporate the repeater in the accordion to do what I want, suggest whatever! I just need to format how the results display how I want, unlike a gridview (I used tables in my normal repeater, and that worked fine, I just need to get that repeater to work inside of the accordion).
(and I know this isn't the section to ask about the accordion, but what is the AccordionExtender? It's not in the toolbox, and I can't find much online. It won't be recognized by Visual Studio, so I don't know what to do. If I could get that, I feel like it could solve my problem, as I found a possible solution online) I don't need to post my code, as it's a simple repeater, and trying to integrate it within the accordion isn't working no matter which way I try since I can't DataBind() in the codebehind. And yes, I tried to FindControl within the accordion but it wouldn't find the repeater.

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>
Expense Management</h3>
</div>
If I place the div outside the telerik control it works fine.
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.

Ok, it is very ugly and I wouldn't have ever tried it myself. It came up in some code that was written years ago but had been working up until this weekend after a bunch of updates were installed on a client's web server where the code is hosted.
The actual result of this is the following html:
<form name="form1" method="post" action="Default.aspx?id=<%= ID %>" id="form1">
The url ends up like this:
http://localhost:6735/Default.aspx?id=<%= ID %>
Which as you can see, demonstrates that the "<" symbol is being encoded before ASP.NET actually processes the page. It seems strange to me as I thought that even though it is not pretty by any means, it should work. I'm confused.
To make matters worse, the client insists that it is a bug in IE since it appears to work in Firefox. In fact, it is broken in Firefox as well, except for some reason Firefox treats it as a 0.
Any ideas on why this happens and how to fix it easily? Everything I try to render within the server control ends up getting escaped.
Edit
Ok, I found a "fix"
<form id="form1" runat="server" method="post" action='<%# String.Format("Default.aspx?id={0}", 5) %>' >
But that requires me to call DataBind which is adding more of a hack to the original hack. Guess if nobody thinks of anything else I'll have to go with that.
I have use embedded code to assign the value to label's text property.But the assign value is not rendering.Here is my code sample,
<%lblProposedYear.Text="Hello"%>
I can not display the text "hello" at the time of page load.

i have a product detail page,in that page i have to dynamically create div and control inside those div also dynamic,no of control based on product
View 1 RepliesI'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler.
The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page.
I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via AJAX client-side.
HtmlTable errors out when I try to use the InnerHtml property (says it isn't supported), and when I try RenderControl, after making first a TextWriter and next an HtmlTextWriter object, I get the error that Page cannot be null.
I'm new to custom server controls and I'm hoping to use them to build various 'modules' for different sites I build to cut down on duplicate code.I'm familiar with custom user controls in which I can create an .ascx & .ascx.vb file which can then be imported into an .aspx page and used freely.However, with custom server controls I cannot find a way of using markup/html code. Is this possible at all or must all code be created programmatically?
