Web Forms :: The Name 'Web Control' Does Not Exist In The Current Context. Error Message In Visual Studio?
Mar 12, 2010
I noticed these errors while building my project (Image#1), but wasn't able to fix them until I declared all of them in the Code behind file (Image #2).It worked fine & I cleared all the errors in al the pages in Visual Studio, BUT the code wouldn't work right on the webpage (Image #3).With this block of Web Controls commented out, I get 3782 errors as you can see below (Image #1). When these blocks are Uncommented, that number goes down to 3755 (Image #2) and eventually clears all error messages.Can anyone assist with this annoyance?

I am facing a weird issue.I have a label on the front end but when I try to use it on the code-behind and run my code I obtain an error: Label does not exist in the current context! The label is shown in intellisense and was working earlier.My team mate had created a back up of the file and it stopped working after that.I deleted the back up files and tried but it doesn't seem to work.
The following is the code snippet of the front end as well as the code behind:
var kisaicerik = CKEDITOR.instances.<% = txtKisaIcerik.ClientID %>.getData();
I am taking this error: The name 'txtKisaIcerik' does not exist in the current context.I know txtkisaicerik is not in my page but it will.I want javascript error's shown in warning or not show.How can i do?

I am getting a very strange error. i have declared a field send_outlook_appt. Even though intellisync is picking up the field name, I am getting an error saying that it does not exist in current context. My program runs as expected in dev. When I try to build/publish my website, that's when I get the error. Here is a snippet from my code.
public class arcTraining { private string connstring = ConfigurationManager.ConnectionStrings["xxxx"].ToString(); protected int _training_id; public int training_id { get { return _training_id; } set { _training_id = value; }
I have an aspx page containing a number of asp:Repeater Controls.Im not using the default code-behind file that is generated, ive changed this to file in a different folder.In the code-behind, i populate the repeater controls, all was workign fine until i added another repeater control to the aspx page.In the code-behind, the intellisense picks up this control and i can access its methods and properties to set the datasource and bind the data. However, when i go to build the project, i get an error "The name Repeater1 does not exist in the current context"Firstly, all the other repeater controls, declared in exactly the same way, do not throw throw this error.Secondly, yes the repeater does have a runat="server" tag.Thirdly, It is not inside any other controls.I have tried various different methods of accessing this repater instead of just "Repeater1." but each returns null:
Ive no idea why this "doesnt exist in the current context" as all the other controls on this page do, even if i create a literal i get the same problem.
I have always used VB for my .NET programming but have recently migrated to C#. I have a really basic problem that I don't understand and am hoping someone can point out why I'm having this issue.
I have a panel which has visible = false by default. Upon a click event of button, it checks current visibility and sets true / false based on current value. I'm getting the above error with the following code, but do not know why. The same code works in VB!
I lifted some nice code to handle memberships, but I want to add a customer specific field. My issue is how to reference my class from the inline c# code.

The problem is the line csUserProperties.AddNew(intUserId, lngCustomerId); -- I get the error "The name 'csUserProperties' does not exist in the current context. I have <%@ Import Namespace="csUserProperties" %> at the top of the file. I also tried everything with no namespace in the class below.
Trying to set up the Login control as a User control, but none of the controls exist in the current context? I also tried adding to a master page with the same error showing up.
None of my code below is recognised? I've rebuilt the solution many times.
if (Membership.ValidateUser(this.UserName.Text, this.Password.Text)) { FormsAuthentication.RedirectFromLoginPage(UserName.Text, RememberMe.Checked); } else { Msg.Text = "Login failed. Please check your user name and password and try again."; }

For some reason my .aspx page gives the msg below:Error 1 The name 'Label1' does not exist in the current context C:Documents and Settings.....MissingFiles.aspx.csIntelisense wont recognize any of my objects such as listboxes...the event are still recognized.
I get the message "The name DropDownList1 does not exist in the current context". Without using a master page, I can get it to work. It's when I bring this code over to a master page is when I get this error. I'm trying to auto populated a drop down list. Here is my code...
public string img_resize(string picname, int maxHeight, int maxWidth) { System.Drawing.Image currentImage = System.Drawing.Image.FromFile(Server.MapPath("image/house") + picname);
