[Solved] Hierarchy code behind

[Shehab]

Hi all,

I am trying to bind the grid in the code behind and also the Hierarchy table with the code behind, I searched in the documentation but couldn't really get to a solution. If you could please direct me to the right spot in the documentation or video or let me know what I am doing wrong, I would really appreciate your help.

Here is my HTML

<radg:radgrid id="dgDep" runat="server" allowsorting="True"
        autogeneratecolumns="False" gridlines="None" Width="689px" Skin="WebBlue">
<MasterTableView DataKeyNames="ContactID,ContactIndic" HierarchyLoadMode="Client">

    <Columns>
      <radG:GridBoundColumn DataField="ContactID" Display="False" HeaderText="UniqueNumber"
            ReadOnly="True" UniqueName="UniqueNumber, ContactIndic">
      </radG:GridBoundColumn>
      <radG:GridEditCommandColumn HeaderText="Edit" UniqueName="EditCommandColumn1">
      </radG:GridEditCommandColumn>
      <radG:GridBoundColumn DataField="Contact" HeaderText="Contact" ReadOnly="True"
            UniqueName="Contact">
      </radG:GridBoundColumn>
      <radG:GridBoundColumn DataField="Ext" HeaderText="Extension" ReadOnly="True"
            UniqueName="Ext">
      </radG:GridBoundColumn>
      <radG:GridBoundColumn DataField="Pager" HeaderText="Pager" UniqueName="Pager">
      </radG:GridBoundColumn>
      <radG:GridBoundColumn DataField="Office" HeaderText="Office" UniqueName="Office">
      </radG:GridBoundColumn>
      <radG:GridBoundColumn DataField="Fax" HeaderText="Fax" UniqueName="Fax">
      </radG:GridBoundColumn>
      <radG:GridBoundColumn DataField="IP" HeaderText="IP" UniqueName="IP">
      </radG:GridBoundColumn>
      <radG:GridTemplateColumn DataField="ContactIndic" HeaderText="Live" UniqueName="ContactIndic">
        <ItemTemplate>
            <asp:CheckBox ID="cbIndic" runat="server" Enabled="false" />
        </ItemTemplate>
        <EditItemTemplate>
            <asp:CheckBox ID="EditLive" runat="server" Checked='<%# Bind("ContactIndic")%>' />
        </EditItemTemplate>
      </radG:GridTemplateColumn>

    </Columns>

    <RowIndicatorColumn Visible="False">
        <HeaderStyle Width="20px" />
    </RowIndicatorColumn>
    <ExpandCollapseColumn>
        <HeaderStyle Width="19px" />
    </ExpandCollapseColumn>
    <DetailTables>
        <radG:GridTableView runat="server" HierarchyLoadMode="ServerBind">
            <RowIndicatorColumn Visible="False">
                <HeaderStyle Width="20px" />
            </RowIndicatorColumn>
            <ExpandCollapseColumn Visible="False">
                <HeaderStyle Width="19px" />
            </ExpandCollapseColumn>
            <Columns>
                <radG:GridBoundColumn DataField="DepID" Display="False" HeaderText="UniqueNumber1"
                    ReadOnly="True" UniqueName="DepID">
                </radG:GridBoundColumn>
                <radG:GridBoundColumn DataField="Contact" HeaderText="Contact" UniqueName="Contact1">
                </radG:GridBoundColumn>
                <radG:GridBoundColumn DataField="EXT" HeaderText="Ext" UniqueName="Ext1">
                </radG:GridBoundColumn>
                <radG:GridBoundColumn DataField="Pager" HeaderText="Pager" UniqueName="Pager1">
                </radG:GridBoundColumn>
                <radG:GridBoundColumn DataField="Office" HeaderText="Office" UniqueName="Office1">
                </radG:GridBoundColumn>
                <radG:GridBoundColumn DataField="IP" HeaderText="IP" UniqueName="IP1">
                </radG:GridBoundColumn>
            </Columns>
            <ParentTableRelation>
                <radG:GridRelationFields DetailKeyField="DepID" MasterKeyField="ContactID" />
            </ParentTableRelation>
        </radG:GridTableView>
    </DetailTables>
</MasterTableView>
        <ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True">
        </ClientSettings>
</radg:radgrid>

And here is the vb code behind.

    Protected Sub dgDep_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.WebControls.GridItemEventArgs) Handles dgDep.ItemDataBound
        'If TypeOf e.Item Is GridDataItem Then
        If TypeOf e.Item Is GridDataItem AndAlso (e.Item.OwnerTableView Is dgDep.MasterTableView) Then
            Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim strChk As String = item.GetDataKeyValue("ContactIndic").ToString()
            Dim chkbx As CheckBox = DirectCast(item("ContactIndic").FindControl("cbIndic"), CheckBox)
            Dim DepID As String = item.GetDataKeyValue("ContactID").ToString()
            If strChk = "1" Then
                chkbx.Checked = True
            Else
                chkbx.Checked = False
            End If

            Dim getDS2 As New DataSet
            getDS2 = dataConn.PhoneGetEachDep(DepID)
            dgDep.MasterTableView.DetailTables.Item(0).DataSource = getDS2

        End If
    End Sub

    Protected Sub dgDep_NeedDataSource(ByVal source As Object, ByVal e As Telerik.WebControls.GridNeedDataSourceEventArgs) Handles dgDep.NeedDataSource
        Dim getDS As New DataSet
        getDS = dataConn.AllDep()
        dgDep.DataSource = getDS.Tables(0).DefaultView
    End Sub
