EntityGridView won't render in design view

Hi - I'm pretty much new to .netTiers (and from what I've seen so far I'm loving it!), so apologies if I'm missing something obvious. However when I try and bind either a GridView or an EntityGridView to one of the new typed entity datasources, it won't render in Visual Studio design mode. Here's an example:

The code for this is shown below: 

One of the reasons I think it might not be my cack-handedness is that I get similar render errors in design view on the Codesmith-generated admin website from the vanilla NetTiers templates, which I've not touched at all. This seems to happen on all the EntityGridViews, and either takes the form above or a different render error, e.g.

Can anyone shed any light on this? I'm using .netTiers v2.0.0.403 templates, the ones that come down automatically with the current version of Codesmith.

Thanks

Rich

I think someone mentioned before, the design time render issue could be due to the empty table that is behind a specific datasource

Hi,

 Just started testing with NetTiers, really cool !

While testing i noticed that a standard ASP GridView or a NetTiers EntityGridView was not rendering in Design time in VS2005 when bound to an specific DataSource like my MovieDataSource.

When trying to combine NetTiers with Ajax and some ControlToolKit-features i noticed that the GridView was showing nicely in design when placed in an UpdatePanel !

 Hope this makes a nice contribution :)

 If you don't like Ajax you can always put EnablePartialRendering of the ScriptManager to false, but still view your Grid in design.
