Hello,
I have a radgrid that contains a detailstable. When I have to delete a parent record, no problem to get datakeyvalues. When I try to delete a child record, I am able to get DataKeyNames but DataKeyValues is empty!

The definition of DetailsTable is this:

<DetailTables>

<telerik:GridTableView name="Partecipanti" TableLayout="Fixed" DataKeyNames="PortalID,UserID,CodRiunione" AllowFilteringByColumn="false"

DataSourceID="objDataSourceGridPartecipantiRiunione" Width="60%" HorizontalAlign="Right"

ShowFooter="false" ShowGroupFooter="false" AllowCustomSorting="false" AllowCustomPaging="false"

CommandItemSettings-AddNewRecordText="Conferma / Rifiuta partecipazione" CommandItemDisplay="Top"

CommandItemSettings-ShowRefreshButton="false"

runat="server">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="PortalID,CodRiunione" MasterKeyField="PortalID,ItemID" />

</telerik:GridTableView>

</DetailTables>

and this is the line I use to retrieve datakeyvalues:

DirectCast(DirectCast(rdgrd_Agenda, Telerik.Web.UI.RadGrid).MasterTableView.DetailTables(0),Telerik.Web.UI.GridTableView).DataKeyValues(e.Item.ItemIndex)("UserID")

The array as Count=0. Where I am wrong?
Thanks
