How to create Self Hierarchy In Grid

[Majid]

Hi,

I want to show parent child hierarchy or self hierarchy but I don't know Levels of Hierarchy.  Next Hierarchy Table should be shown on based of some decision from code. I have seen one example http://www.telerik.com/help/aspnet-ajax/grid-self-referencing-hierarchy.html But It didn't allow any CRUD operations.

I want to do this by Coding and How can I add more GridTableView in Existing GridTableView? Below is Grid Code

<telerik:RadGrid ID="BicCodeGrid" runat="server" AutoGenerateColumns="false" OnNeedDataSource="BicCodeGrid_NeedDataSource"
                    Skin="Silk" OnItemCommand="BicCodeGrid_ItemCommand" OnDetailTableDataBind="BicCodeGrid_DetailTableDataBind"
                    OnItemDataBound="BicCodeGrid_ItemDataBound" >
                    <MasterTableView Width="100%" DataKeyNames="BICCodeID" ClientDataKeyNames="BICCodeID"
                        HorizontalAlign="NotSet" AutoGenerateColumns="False">
                        <Columns>
                            <telerik:GridBoundColumn HeaderText="Kode" DataField="BICCode" UniqueName="BICCode"
                                ReadOnly="true" ItemStyle-Width="50px">
                            </telerik:GridBoundColumn>
                            <telerik:GridBoundColumn HeaderText="Område" DataField="DanishDescription" UniqueName="DanishDescription"
                                ReadOnly="true" ItemStyle-Width="400px">
                            </telerik:GridBoundColumn>
                            <telerik:GridButtonColumn ButtonType="PushButton" Text=" + " CommandName="AddBicCode">
                            </telerik:GridButtonColumn>
                        </Columns>
                        <DetailTables>
                            <telerik:GridTableView DataKeyNames="BICCodeID" Name="DetailsTable" Width="100%" on>
                                <ParentTableRelation>
                                    <telerik:GridRelationFields MasterKeyField="BICCodeID" DetailKeyField="ParentID" />
                                </ParentTableRelation>
                                <Columns>
                                    <telerik:GridBoundColumn HeaderText="Kode" DataField="BICCode" UniqueName="BICCode"
                                        ReadOnly="true" ItemStyle-Width="50px">
                                    </telerik:GridBoundColumn>
                                    <telerik:GridBoundColumn HeaderText="Område" DataField="DanishDescription" UniqueName="DanishDescription"
                                        ReadOnly="true" ItemStyle-Width="300px">
                                    </telerik:GridBoundColumn>
                                    <telerik:GridButtonColumn ButtonType="PushButton" Text=" + " CommandName="AddBicCode">
                                    </telerik:GridButtonColumn>
                                </Columns>
                            </telerik:GridTableView>
                        </DetailTables>
                    </MasterTableView>
                    <ClientSettings>
                        <ClientEvents OnCommand="RaiseCommand" />
                    </ClientSettings>
                </telerik:RadGrid>

Hi Majid,

Instead of using RadGrid with self referencing hierarchy for your scenario, better option would be to use the RadTreeList control which fully covers your requirements and supports CRUD operations as per your needs. See the online demo below for more information on this matter:
