Hello,

I'm urgently trying to bind a RadTreeList to an EntityDataSource.

    <telerik:RadTreeList runat="server" DataKeyNames="Id" ParentDataKeyNames="TreeElementId" DataSourceID="MediaAssetGroups" AutoGenerateColumns="false" ID="rtlCategories" OnItemInserted="rtlCategories_ItemInserted">
        <Columns>
            <telerik:TreeListBoundColumn DataField="Id" HeaderText="ID" ReadOnly="false"
                UniqueName="EmployeeID" HeaderStyle-Width="60px" ForceExtractValue="Always" Visible="false">
            </telerik:TreeListBoundColumn>
            <telerik:TreeListBoundColumn DataField="Name" HeaderText="Name" ReadOnly="false"
                Visible="true">
            </telerik:TreeListBoundColumn>
            <telerik:TreeListBoundColumn DataField="Description" HeaderText="Beschreibung" ReadOnly="false"
                Visible="true">
            </telerik:TreeListBoundColumn>
            <telerik:TreeListCheckBoxColumn DataField="IsGlobalCategory" DefaultInsertValue="true" HeaderText="Globale Kategorie">

            <telerik:TreeListCheckBoxColumn DataField="IsActive" DefaultInsertValue="true" HeaderText="Aktiv">

            <telerik:TreeListCheckBoxColumn DataField="IsDeleted" DefaultInsertValue="false" HeaderText="Gelöscht" Visible="false">

                        </asp:TableCell>
                        <asp:TableCell>

                            <asp:Button ID="btnCancel2" Text="Cancel" runat="server" CausesValidation="False"
                                CommandName="Cancel"></asp:Button>
                        </asp:TableCell>
                    </asp:TableRow>
                </asp:Table>
            </FormTemplate>
        </EditFormSettings>
    </telerik:RadTreeList>

    <asp:EntityDataSource ID="MediaAssetGroups" runat="server"
        ConnectionString="name=X_DatabaseContainer"
        DefaultContainerName="X_DatabaseContainer" EnableFlattening="False"
        EntitySetName="TreeElementSet" EntityTypeFilter="MediaCategory" EnableInsert="True" EnableDelete="True" EnableUpdate="True"
        Include="" OrderBy="it.Name ASC"
        Where="it.IsDeleted = false">
    </asp:EntityDataSource>

The Problem now is, that everything works fine except of inserting items below other items. Then the freshly created item will show up below root and not the selected parent.

The Id and the TreeElementId are of type Guid.

Has anybody a suggestion for this behaviour?

Hi Aljoscha,

In order to add a new item under some item you need to gets its ID first and set it as a ParentID of the new item so basically you can not use Guid value. I would recommend you to examine the following live example which demonstrates how to achiever that.
