Error after adding a textfield to a form: 'Registration_Form' does not contain a definition for 'urlAddress'


I'm working on a little project, exploring VisualStudio 2005 and C#. I am currently updating a simple registration form: a few fields for username, password, email, etc.. I took the existing form and I am now trying to add a UrlAddress field so the user can put in a link to a personnal web site. I am using a HtmlTextInput control. Here's the line from the .Aspx file:


input id="urlAddress" style="width: 409px" runat="server"/>

And this is the code from the Code-Behind file executed by the submit button:


void Register() {
User usr = null;
try {
        usr =
new User();
new AppSettingsReader().GetValue("DBConnectionString", typeof(string)).ToString(),
this.username.Value, this.password.Value, this.lastname.Value, this.firstname.Value,, 
"RegComp.aspx?Type=Tutor", false);
} catch (Exception ex) {
if (Trace.IsEnabled)

User is a business object from the Business Tier. There's also a Data Tier. Everything goes fine when I run the application. The user is correctly added to the database. However, I keep getting an error in the Code Editor everytime I try to run the web application saying 'Registration_Form' does not contain a definition for 'urlAddress'.

Anyone has an idea about what I could have done wrong???

Why did you use HtmlTextInput control instead of Asp:Textbox?

You see this error normally because you do not have your asp control declared/initialized in the code behind.

Hope this helps.

I am using HtmlTextInput because that's what was used for the other fields. I tried with an asp:Textbox and I get the same error. In fact, I got this error with every control I tried.

I tried declaring explicitly the control in the code behind file but I get a 'Registration_Form' already contains a definition for 'urlAddress'.

I looked in older projects I made using VS 2003 and I noticed there is some code generated by VS to declare the controls used in the page. In VS 2005, if I understood correctly, this code appears in a partial class located in a different file than the one I'm writting code in. However, I can't find the other file. Where should it be located?

Is it possible that when the source code was copied and given to me, the other part of the class would have been in a hidden file and I did not receive it?
If this is the case then I suppose I still have access to the other components because the partial classes I don't have are already compiled in an assembly.

Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error: Cast from type ''''DBNull'''' to type ''''String'''' is not valid. I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL. Is there another way around this? Check if it is equal to DBNull.Value first and if it is, don't do the cast.Stanley Tan theSpoke Blog Where in the code does it need to go?
