Hello there,

Do the gridview support making a six level hierarchy in an easy way? 

Right now I'm setting my top data set as ItemsSource and then do a lot of child table definitions. To be able to remove GroupPanel and ColumnHeaders in my child nodes I'm listening on the DataLoading event casting the sender to a GridViewControl. For getting all the child column I have set the AutoGenerateColumns property to true. But I need to remove some of them so I also listening for AutoGeneratingColumn event. Doing this seems a little bit odd!

Another question is if I'm able to update the data at the bottom node in the gridview from a database without destroying the expanded hieararch made by the user?

Am I correct in my assumption that the gridview only support a two level hierarchy in a good manner.

Best wishes from Johan

Hi Johan,

Actually the grid can have unlimited levels of hierarchy - you can check this thread for example. The application is for Silverlight however the approach can be used in WPF as well.

Hello Vlad and thanks for the response.

I had some problem with opening the Silverlight solution. I'm using VS9 so there shouldn't be any problem.
The error message was: Couldn't open project file SilverlightApplication.csproj. The project type is not supported by this installation.

Is there a way I could get my hands on a WPF-example with a huge hierarchy?

Regards
Johan

Hello Johan,

You can check Mainpage.xaml + cs for more info about the implementation.

Kind regards,
