Hi, I currently have my RadGrid setup with DetailTables, but I would like to switch to NestedView to have more control over the presentation of the data.  For my Detailtables I useOnDetailTableDataBind, but the NestedView doesn't have that property.  What is the best route take if I have a datasource that can only be generated programmatic?

<telerik:RadGrid ID="RadGrid1" runat="server"
    AllowSorting="True" GridLines="None" ShowGroupPanel="True"
    OnNeedDataSource="RadGrid1_NeedDataSource"
    OnDetailTableDataBind="RadGrid1_DetailTableDataBind"
    AllowFilteringByColumn="True">
    <ClientSettings AllowColumnsReorder="True" AllowDragToGroup="True" ReorderColumnsOnClient="True">
        <Selecting AllowRowSelect="True" />
    </ClientSettings>
    <MasterTableView  DataKeyNames="ID" AllowMultiColumnSorting="True">
        <DetailTables>
            <telerik:GridTableView DataKeyNames="ID"  Width="100%"
                runat="server" AutoGenerateColumns ="false">
                <Columns>
                    <telerik:GridBoundColumn SortExpression="Joined" HeaderText="Joined" HeaderButtonType="TextButton"
                        DataField="Joined" UniqueName="Joined">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn SortExpression="Status" HeaderText="Status" HeaderButtonType="TextButton"
                        DataField="Status" UniqueName="Status">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn SortExpression="City" HeaderText="City" HeaderButtonType="TextButton"
                        DataField="City" UniqueName="City">
                    </telerik:GridBoundColumn>
                </Columns>
            </telerik:GridTableView>
        </DetailTables>
        <NestedViewSettings>
         
        </NestedViewSettings>
    </MasterTableView>
</telerik:RadGrid>

Hello Michael,

You can attach NeedDataSource event to inner grid and bind it through the NeedDataSource event. In the inner grid NeedDataSource event, you can get reference to the outer grid expanded item, e.g. the parent item. Thus you can get a data field value of the expanded item and use it for retrieving the inner grid data source.

For more information on this, please refer the following forum.

Thanks,
Princy.
