Instantiation of custom control inside compiled codebehind

8/4/2003 1:17:28 PM

0/0

I am using a custom control and am trying to assign to it's properties from within a compiled codebehind page, however when I run the page I get an error saying that the control isn't instantiated. The code I am using is as follows:

..aspx:

<%@ Page Language="C#" Codebehind="LSO.CodeBehind.cs" Inherits="LSO.CodeBehind.Default"%>
<%@ Register TagPrefix="LSO" Namespace="LSO.Controls" Assembly="LSO.Controls" %>
....
<LSO:Concert id="NextConcert" runat="server" />

codebehind (C#):

....
using LSO.Controls;

public class Default : Page {

Concert NextConcert;

public void Page_Load ( Object src, EventArgs eArgs ) {

NextConcert.Date = Application [ "NextConcertDate" ].ToString ();
NextConcert.Venue = Application [ "NextConcertVenue" ].ToString ();
}
}

Obviously simply instantiating the Concert object wouldn't tie it to the control on the .aspx page. Any explanation on how to accomplish this would be a great help.

Thanks, Steve

The problem seems to be that your "NextConcert" member variable is defined as private so it won't be accesible to the parser generated class. For the parser to do its magic you need to define a member variable whose name exactly matches the ID given to your custom control ni the .aspx/.ascx (which seems to be fine in your example) and also make the member variable not private (protected would be ideal).

If this doesn't help please post the exact error message you're getting

Thanks Victor,

That may well be the problem, however I have now got another problem that you may be able to solve.

I was using the 1.0 SDK but upgraded to 1.1 today and now I can't use the csc compiler (error: 'csc' is not recognized as an internal or external command, operable program or batch file.)

Any ideas?

Cheers, Steve

csc.exe should be in your framework directory, check if you path include the directory. It's usually in [drive][windows directory]\Microsoft.Net\framework\v1.1.4322\
