Code Behind Doesn't Recognize Control ID's On HTML Page
Feb 9, 2010
I had a website with a few asp.net controls with id like:
btnSave and tbAmount
I renamed one of my controls and when I tried to use it in the code behind I get the following error.
Error 5 Name 'tbAmount' is not declared.
I was messing around trying to add new controlls rather than rename, but nothing seems to work.
And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:
Error 5 Name 'tbAmount' is not declared.
Or
Error 3 Name 'hfNoteId' is either not declared or not in the current
scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.

on a server, I am trying to deploy a website. Originally, the page styles did not work and the some of the .gif and .jpg images didnt show up. I fixed the css problem by adding a http handler mapping through IIS. I tried the same thing to get the images to work but that didn't fix the problem. If the website was fully deployed im pretty sure the images would work so I dont want to change their paths (same with css). The handler mapping i added for css was for "*.css" of type system.web.staticfilehandler. This is the same type i tried for .jpg and .gif. I don't know specifically the purpose of system.web.staticfilehandler because msdn info is very short.

In my current project (ASP.Net 2.0) I have a lot of web user controls, among them "Office.ascx". Office.ascx is loaded into another controls using this line:
guide_controls_display_Office o = (guide_controls_display_Office)LoadControl("Office.ascx");
The control I am loading it into has Office.ascx registered using this line:
<%@ Register TagName="office" TagPrefix="uc" Src="Office.ascx" %>
But I get this error upon launching the web page: Unable to cast object of type 'ASP.guide_controls_display_office_ascx' to type 'guide_controls_display_Office'. Why do I get this message? I can see that the first type has "ASP." in front of it. Is that normal?

I have created a user control which is inside a folder called Controls and the class is a partial class which inherits from Web.UI.UserControl. Now from my page which is one level up I just try to access the method inside the usercontrol and so trying to cast it as the type of user control. But I get build errors. It just cannot recognize that class. I get Type not defined error. But at times it has recognized the class. Dont know why it does that.

I have a custom control in my mater page that represents a menu, let's call it CustomMenu. The control code files are located in a non special directory. I want to give each page that uses that master page the ability to access the control and, using a public property, tell the control whether or not it should render itself. I have a public property on the control to do that, and I know I can get the control by referencing Page.Master.FindControl('IdOfControlIwant');
The problem I'm having is that I can't seem to get the control Type recognized by the compiler, so when I do find the menu control, I can't actually work with it. The only way I can get the code behind to recognize the type is to register it in the ascx file, and then add at least one control to the page, which is undesirable.

My site was working fine in Visual Studio 2008, but the code-behind pages have suddenly stopped recognising new controls which I add to the main page. For example I added a label with id 'lblEventHeader' to the main page and then tried to set a text property in the Page_Load event. I get a compile error of "the name 'lblEventHeader' does not exist in tne current context. Existing controls, which I added before this problem seems to be unaffected.
As far as I am aware, I have not done anything which should cause this. I have even reinstalled Visual Studio, but I still get the same error message. Have I inadvertently deleted or corrupted a reference file. I have checked the Codefile and Inherits properties of the page.

I have created profile objects in my web.config file:
[Code]....
[Code]....
In all tutorials I am finding on the net it says in order to read/write from these properties I just need to use the syntax with C#:
Profile.Surname = "Surname";
But this does not work on my web site code when I'm using C# it underlines and recommends I change to System.Web.Profile.Surname (which I do) but then Intellisense and the compiler do not recognise Surname. What am I doing wrong? I am using Visual Studio 2010 and .Net V4.

Private Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
' The deletion of the individual row is automatically handled by the GridView.
Dim dbDelete As New pbu_housingEntities
' Remove individual from the bed.
Dim remove_bed = From p In dbDelete.Beds _
Where p.occupant = GridView1.Rows(e.RowIndex).Cells(3).Text _

Where p.building = GridView1.Rows(e.RowIndex).Cells(5).Text _
Order By p.id Descending _

The specific line erroring out is: remove_bed.First.occupant = ""

how to generate HTML code from the code behind?
I would like to build a form that generate an html code inside a for loop.
I will let the user enter the photo name and No. of photos
Then I will generate an HTML code like this:
<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />
depending on the No. of the photos the code will be duplicated in the loop
Then I will display the result of the loop in label or in a textarea to let the user copy it any where
The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses

I receive this error message: LINQ to Entities does not recognize the method 'System.Guid GetUserId()' method, and this method cannot be translated into a store expression. This is my code:
DB.Users user = db.Users.FirstOrDefault(u => u.Id == BOL.GetUserId());
BOL.GetUserId() returns a GUID of the current logged-in user (and this works works).
How can I make this LINQ code line work? Or, what is the shortest alternative? In the mean time I found out that there is a difference between LINQ to SQL and Entities. I use Entities because of the TailspinSpyworks example... but my code is using LINQ to SQL. My current solution is to use a var:
var userId = BOL.GetUserId();
DB.Users user = db.Users.FirstOrDefault(u => u.Id == userId);
Is this a good solution? And, is the execution time of Entities faster than SQL?

So I created a site optimized to be rendered in a mobile device. I set the Width Site is looking good on Blackberry of my <DIV> tags to be about 300px, for the most part, to account for the reduced screen size. However, the IPhone Safari browser renders this to the screen extremely small, and I can only assume that it's automatically reducing the size of the html accordingly to fit the device. Again, Blackberry does not do this.

I migrating a large asp.net webform site to MVC. I want to mix match old asp.net web form and asp.net mvc together for sometime and gradually convert the webform model to pure mvc model.
So i copied all aspx/ascx files from the old webform site to my mvc project. Now when i compile, i get build error. Code behind files can not find any server controls inside their aspx pages.
I can solve this problem by adding a desinger.cs file for each of the aspx,ascx file but that simply is not viable for me since i am dealing with hundreds of aspx pages and user controls and i can not afford to manually add a designer file for each of them.

I have a .aspx page in c#. There is an ajax control that shows the data company names from the xml file when the city is selected.
There is also a bing search control on the page.
The issue is that the Ajax control stops populating the data when the search control is present on the page.
The ajax control works absolutely fine when the search control is removed
