[Solved] Insert child object in gridview

</telerikGridView:RadGridView>

I am using a domaindatasource to display a list of Items in a gridview.  Each Item can have zero to 1 Note objects.  I can successfully display the Item data (not pasted in xaml) and the Note.NoteText for an existing note, and I am also able to edit existing Items and Notes.  However, i can't figure out how to insert a new Note if the Item doesn't already have one.  Whenever i enter text for a new Note, the text disappears when i am finished editing the cell.  On the server-side I am using EF and Ria Services.  I have the Includes statements in my metadata and service queries.  I also have insert and update statements for both POItem and Note. 

Is it possible to insert a child object in this situation?

Hi david mcintyre,

Basically, there should be no problem to insert items in the parent and child grids. You may take a look at this forum thread for further reference on the necessary settings about implementing this functionality.
Considering the case that the just-entered value in the cell disappears, I am not quite capable of making an appropriate suggestion without any additional details. Is that behavior only for the child grid - with the nodes or for the parent grid too ? Do you handle in any way the CellEditEnded event ?

All the best,
