                            <YearView UserSelectable="true" />

                            <Columns>

                                <telerik:GanttBoundColumn DataField="Title"></telerik:GanttBoundColumn>

                                <telerik:GanttBoundColumn DataField="Start"></telerik:GanttBoundColumn>

                                <telerik:GanttBoundColumn DataField="End"></telerik:GanttBoundColumn>

                                <telerik:GanttBoundColumn DataField="Duration" DataType="DateTime" HeaderText="Duration" DataFormatString="{0:HH\:MM\:SS}"></telerik:GanttBoundColumn>

                            </Columns>

                            <DataBindings>

                                <TasksDataBindings IdField="ID" TitleField="Title" StartField="Start" EndField="End"

                                    PercentCompleteField="PercentComplete" OrderIdField="OrderID" SummaryField="Summary" ParentIdField="ParentID" />

                                <DependenciesDataBindings IdField="ID" PredecessorIdField="PredecessorID"

                                    SuccessorIdField="SuccessorID" TypeField="Type" />

                            </DataBindings>

                        </telerik:RadGantt>

while (reader.Read())

                    {

                        Task t = new Task();

 

                        t.ID = reader.GetValue(0);

                        t.Title = reader.GetString(1);

                        t.Start = reader.GetDateTime(2);

                        t.End = reader.GetDateTime(3);

                        t.PercentComplete = decimal.Parse(reader.GetValue(4).ToString());

                        t.OrderID=1;

                        t.ParentID = reader.GetValue(5);

                        sessionTasks.Add(t);

                    }

RadGantt1.DataSource = Tasks;
           RadGantt1.DependenciesDataSource = Dependencies;

Hello Mohammad,

I have performed some local tests, using the demonstrated implementation that you have set at your and the parent/child hierarchy is correctly achieved at my end. Please make sure that the ParentID fields are correctly set in your datasource, so that the RadGantt control could read them properly and visualized the hierarchy.

If you still experience any issues, please submit a support ticket and provide us with a simplified runnable sample, along with the datasource that you use, so we could inspect it locally and troubleshoot the problem for you.
