BUG? Multiple controls with the same ID

Bal Ghuman

Hi Guys

I've got an ASP.NET application that dynamically creates a navigation table
from an XML file and then Loads a user control according to which link has
been selected. The control overrides the pages functionality using
'TemplateContro l.LoadControl' to dynamically load a UserControl (.ascx)
that implements HttpContext.Cur rent.Cache functionality. The application
works fine in our development environment but when deployed live the
following error is randomly generated:

ERROR = System.Web.Http Exception: Multiple controls with the same ID
'tr_xxx' were found. FindControl requires that controls have unique IDs. at
System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,
ControlCollecti on controls) at
System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,
ControlCollecti on controls) at
System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,
ControlCollecti on controls) at
System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,
ControlCollecti on controls) at
System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,

System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,
ControlCollecti on controls) at
System.Web.UI.C ontrol.FillName dControlsTable( Control namingContainer ,
ControlCollecti on controls) at

I havn't included any code snippets as the application works fine and this
is a totally random error which occurs infrequently. The application is
hosted on a W2K Server and is built in the 1.0 Framework. I read the
following article by Microsoft, but installing this patch knocked out the
application.

http://support.microsoft.com/default...b;EN-US;834608

I'm in a quandary with this one, any pointers would be most appreciated.

Thanks in advance....

Looks like that fix is for framework 1.1, may not work for 1.0.

Here's a post w/ more details on apparently what's happening:

Thanks for the pointers, because the error is so random its almost
impossible to nail down. Over the past few weeks I've tried a few options,
including rebuilding the application in the 1.1 Framework. But the patch
Microsoft released is problematic and they are due to include a revised
version in their next Service Pack.

ParseControl With Multiple Controls in One Input String

According to the documentation, ParseControl returns a parsed control from an input string. The documentation seems to assume that *one* control will be parsed from the string.

In my testing, it appears that ParseControl will successfully...
