I'm using RadGridView with DomainDataSource.
<riaControls:DomainDataSource x:Name="dds" LoadSize="40" PageSize="20" QueryName="GetPaisQuery">
<riaControls:DomainDataSource.DomainContext>
<ClientServ:SmartBusinessDomainContext/>
</riaControls:DomainDataSource.DomainContext>
</riaControls:DomainDataSource>
<telerikGridView:RadGridView x:Name="grid" Grid.Row="1" AutoGenerateColumns="True" ItemsSource="{Binding Data, ElementName=dds}" AddingNewDataItem="grid_AddingNewDataItem"></telerikGridView:RadGridView>
A collection of entities of DomainDataSource is initially empty, since no record in the database! Until then fine!
The problem happens when I add a new record triggering RadGridView.BeginInsert ()
In the event AddingNewDataItem I'm doing the following:
object newEntity = (this._DataSource.Data as System.ComponentModel.IEditableCollectionView).AddNew();
object newEntity = (this._DataSource.Data as System.ComponentModel.IEditableCollectionView).AddNew();
e.NewObject = newEntity ;
The new line is inserted in RadGridView, but she is in a way that I can not write into the cell.
The interesting thing is that I do the same procedure, but instead of a collection of empty and contains DomainDataSource start a registry, it lets me insert a new record quietly.
What may be happening?

Hello thiago_zueranet,
I'm attaching a running example base on your code snippet.
If you intend to add new default object and of course object has parameter less constructor you do not need RadGridView.AddingNewDataItem event. This event is designed to help to insert externally created objects from same type as RadGridView.ItemsSource elements. In this event you should avoid call to AddNew() method, because this method actually add item into collection and RadGridView call AddNew() internally, so you result with 2 new rows. You just need to set e.NewObject to your object.
About the editing issue, it seems that you've hit a bug in our control. The problem is that from this kind of data source RadGridView doesn't reflect correctly GridViewDataColumn.DataType property, so RadGridView cannot create proper GridViewCellEditor. This issue is logged and will be fixed with some of the next releases. I've updated your Telerik points accordingly.
Meanwhile you can set GridViewDataColumn.DataType for your columns (as shown in the example) this will enable editing.
Sincerely yours,
