cannot access container data in templated control

[Achim Domma (SyynX Solutions GmbH)]

Hi,

I have implemented a templated control like described in the MSDN and
the Quick Start tutorial. In my aspx page, the control is used like this:

<syynx:SelectTableControl id="test" runat="server">
<Item>blabla <%# Container.Pos %><br></Item>
</syynx:SelectTableControl>

Below you can see the implementation of the templated control and the
container item. If the page is displayed, I only get five times 'blabla
<br>', so the property Pos seems to be ignored.

If I rename Pos to an invalid name I get an error. If I set a breakpoint
into the get method of Pos, I can see that the property is never accessed!?

Am I missing something? Any hint would be very appreciated!

regards,
Achim
