Hi,
I tried the example in the topic 216 Add-Delete on Child Grid, try to delete a row in the grid using the DEL key but nothing happens. The userdeletingrow event never fires. What can be wrong? I have the same situation in my app, so i'd like to know what is missing here.
Thanks.

There are many code examples in 216 Add-Delete on Child Grid.  Which code example or tutorial are you referring to?
 
Are you using .NET, DevForce, or Infragistics grid?
 
If DevExpress or Infragistics, what version are you using?

The example i'm refering it's the one that shows the way to delete  an object by selecting its row and pressing the DEL key, i'm using VB NET 2005 and the .NET grid.

This is the code in the example mentioned:

  Private Sub OrdersDGV_UserDeletingRow( _

ByVal sender As Object, _

      ByVal e As System.Windows.Forms.DataGridViewRowCancelEventArgs)

    OrderDelete(CType(e.Row.DataBoundItem, Order))

    e.Cancel = True

  End Sub

Hi,
I remember having problems with that example too. As far as I remember the UserDeletingRow event is not fired because the Child-list is readonly.
Another drawback is that it is possible to add many row to the collection without seiing them (playing with the up, down key for example)

The easiest way I found to have the default dotnet grid behaviour was to use a list for the details grid and to update the binding on the MasterBindingSource.CurrentChanged event.
