I have a GridView that works fine, but now I have to expand the GridView to have a Details grid inside which have another datacontract then its parent GridView. The relation between the two datacontracts is an ID. I am using MVVM. I can not find anything about this in the documentation, so some examples or help would be much appreciated.

Grid stealing focus when row is added

How can I prevent the grid from stealing focus when a new item is added to the underlying collection?

For example, I have two seperate windows, one which displays the grid, another through which the user may add new rows to the grid. I would like focus to remain on the add window when the user adds a new row, but the grid by default seems to be setting focus to the first editable cell in the new row.

Thanks

RadDatePicker: how can we change the culture on-the-fly?

From the example code, we see that we can change the culture in Xaml

<telerikInput:RadDatePicker x:Name="datePicker" HorizontalAlignment="Left" Margin="10" Width="200" Culture="en-US" />
we can change Culture as any language in the drop down list such as chinese:

<telerikInput:RadDatePicker x:Name="datePicker" HorizontalAlignment="Left" Margin="10" Width="200" Culture="Chinese (People's Republic of China)" />

We need to change the culture on-the-fly. Can we do it on the Xaml?
If not, we have to do it through code-behind.
How do we get the list of culture list as above string?
thx!
