Get DataKeyValues from child ItemCommand event in NestedViewTemplate

[Jose]

Hello,

I've seen a lot of examples to access to DataKeyValues from DetailTables, but I cannot find an example about doing the same in NestedViewTemplates.

Here is my RadGrid:

<telerik:RadGrid ID="ListGrid" runat="server" AllowFilteringByColumn="True"
     AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"
     GridLines="None" ShowStatusBar="True" ShowGroupPanel="True"
     onneeddatasource="ListGrid_NeedDataSource"
     onitemcommand="ListGrid_ItemCommand">

     <ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True"
         AllowDragToGroup="True">
         <Selecting AllowRowSelect="True" />
     </ClientSettings>

     <MasterTableView DataKeyNames="CustomerId" CommandItemDisplay="Top">
         <CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>

         <RowIndicatorColumn>
             <HeaderStyle Width="20px"></HeaderStyle>
         </RowIndicatorColumn>

         <ExpandCollapseColumn>
             <HeaderStyle Width="20px"></HeaderStyle>
         </ExpandCollapseColumn>

         <NestedViewTemplate>
             <asp:Panel runat="server" ID="InnerContainer" CssClass="viewWrap">
                 <telerik:RadTabStrip runat="server" ID="CustomersTabStrip" MultiPageID="CustomersMultipage" SelectedIndex="0">
                     <Tabs>
                         <telerik:RadTab runat="server" Text="Contacts" PageViewID="ContactsPageView">
                         </telerik:RadTab>
                         <telerik:RadTab runat="server" Text="Addresses" PageViewID="AddressesPageView">
                         </telerik:RadTab>

How can I get parent DataKeyValues from a child ItemCommand event? I need the CustomerId value in order to pass this parameter to another page.

Any idea?
Thanks a lot in advanced,
Jose

Hi Jose,

Here is a help article which explains how to extract primary key value for parent item in hierarchy on Update/Insert. Go through it and see if it helps.

Hi Pavlina,

Thank you very much for your support.
Before posting my question I was reading this support document and I tried implementing it, but when I run this code parentItem always is null.

If you check my code, I think that this may be because the child grid is inside a MultiPage control, inside a RadTabStrip control, inside an panel.

Any idea?
Regards
Jose

Hello Jose,

To get the parent item's data key value you can use the following approach:
C#:

((GridNestedViewItem)e.PageView.MultiPage.NamingContainer).ParentItem.GetDataKeyValue("YourDataKeyID");

I hope this helps.
