Hi guys!!!, Im realy scared in my RadGrid appear a ghost row, when this show 2 or more rows whit child, this event takes place when in other RadGrid changes the selection item, attach image, my code for this radGrid is the next:
                    DataTable _dtStudy =  wpfWebServexCore.ServiceGeneralClass.studys(((DataRow)rgvPatients.SelectedItem).ItemArray[0].ToString());
                    _idPatient = ((DataRow)rgvPatients.SelectedItem).ItemArray[0].ToString();
                    rgvSeries.ItemsSource = _dtStudy;
                    rgvSeries.DataMember = _dtStudy.TableName;
                    if (rgvSeries.TableDefinition.ChildTableDefinitions.Count > 0)
                    {
                        for (int i = 0; i < rgvSeries.TableDefinition.ChildTableDefinitions.Count; i++)
                        {
                            rgvSeries.TableDefinition.ChildTableDefinitions.RemoveAt(i);
                        }
                    }

                    foreach (DataRow _dr in _dtStudy.Rows)
                    {
                         
                        GridViewTableDefinition definition = new GridViewTableDefinition();
                        definition.AutoGenerateFieldDescriptors = false;
                        definition.DataSource = wpfWebServexCore.ServiceGeneralClass.series(_dr["StudyInstanceUID"].ToString());

                        //rgvSeries.UpdateLayout();

                        TableRelation _relation = new TableRelation();
                        _relation.FieldNames.Add(new FieldDescriptorNamePair("StudyInstanceUID", "StudyInstanceUID_FKey"));
                        definition.Relation = _relation;

                        rgvSeries.TableDefinition.ChildTableDefinitions.Add(definition);
                       
                        rgvSeries.AddHandler(GridViewDataControl.RowValidatingEvent, new EventHandler<GridViewRowValidatingEventArgs>(this.selectChild_clik));
                        
                    }
                    ((ExpandableDataRecord)rgvSeries.Records[0]).IsExpanded = true;
                    wpfWebServexCore.ClassGlobal.DtStudy = _dtStudy;
                    rgvImages.ItemsSource = new DataTable();

Hello Armando ,

If you want to check our beta you can download it from Your Account->Free Trials->Rad Controls for WPF->Q3 2009 Beta 2.

Otherwise you can wait until next week when our Q3 2009 official release will be shipped.
