Multiple controls with the same ID

[shiretu]

Hi,

I'm trying to make a WebPropertyGrid control in ASP.NET. The control
renders itself as expected when the request is a "GET". When I make a
POST, I get the following error:

Multiple controls with the same ID 'TestString' were found. FindControl
requires that controls have unique IDs.

The architecture of my control is quite simple: using reflection I read
the properties from an object and generate appropriate web controls for
the user. For basic types like int,long,string,DateTime, etc I make an
TextBox. For complex types (those who are not in the list before) I
recursively make another WebPropertyGrid. My WebPropertyGrid structure
is initialized in CreateChildControls overridden method. After that I
call the base method. The CreateChildControls method works fine even
when I receive the error message into the browser. I suspect the
problem is in the rendering part....


ANY input is greatly appreciated

Additional info on the subject....


I implement INamingContainer and the control used for rendering
DateTime type is an custom control who also implements
INamingContainer.
Every id in the HTML output is ok. There are no duplicates......
