Using griddata in grid under nestedview

[Ahrensberg]

Hi all,

I have a grid containing orders with IDs. This main grid have a nestedview in which I have a tab containing some text and another containing a new grid with the orderlines.

How can I give the information about the order id to the grid containing the orderlines. My code looks something like beneath (I have cutted out a lot of code to get a better overview of the essential code):

<telerik:RadGrid ID="RgOrders" AutoGenerateColumns="false" OnNeedDataSource="RgOrders_NeedDataSource" runat="server">
    <MasterTableView ClientDataKeyNames="id">
        <Columns>
            <telerik:GridBoundColumn DataField="OrderNumber" HeaderText="OrderNumber" UniqueName="OrderNumber" />
            <telerik:GridBoundColumn DataField="OrderFirstName" HeaderText="OrderFirstName" UniqueName="OrderFirstName" />
            <telerik:GridBoundColumn DataField="OrderLastName" HeaderText="OrderLastName" UniqueName="OrderLastName" />
        </Columns>
        <NestedViewTemplate>
            <asp:Panel runat="server" ID="OrderNestedView" Visible="false">
                <telerik:RadTabStrip runat="server" ID="TabStrip1" Visible="true" SelectedIndex="0" MultiPageID="Multipage1" Align="Justify">
                    <Tabs>
                        <telerik:RadTab runat="server" Text="OrderInformation" PageViewID="PageViewOrderInformation">
                        </telerik:RadTab>
                        <telerik:RadTab runat="server" Text="OrderLines" PageViewID="PageViewOrderLines">
                        </telerik:RadTab>
                    </Tabs>
                </telerik:RadTabStrip>
                <telerik:RadMultiPage runat="server" ID="Multipage1" SelectedIndex="0" RenderSelectedPageOnly="false">
                    <telerik:RadPageView runat="server" ID="PageViewOrderInformation">
                        [... some orderinformation ...]
                    </telerik:RadPageView>
                    <telerik:RadPageView runat="server" ID="PageViewOrderLines">
                        <telerik:RadGrid ID="RgOrderLines" AutoGenerateColumns="false" OnNeedDataSource="RgOrderLines_NeedDataSource" runat="server">
                            <MasterTableView>
                                <Columns>
                                    <telerik:GridBoundColumn DataField="OrderLineNumber" HeaderText="OrderLineNumber" UniqueName="OrderLineNumber" />
                                    [... some more GridBoundColumn ...]
                                </Columns>
                            </MasterTableView>
                        </telerik:RadGrid>
                    </telerik:RadPageView>
                </telerik:RadMultiPage>
            </asp:Panel>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

Hi,

You can access the DataKeyValue field of the main grid in the NeedDataSource event of the nested grid as shown in the example below:
aspx:

<telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource" runat="server">
    <MasterTableView DataKeyNames="ID">
        <Columns>
           ....
        </Columns>
        <NestedViewTemplate>
            <asp:Panel runat="server" ID="NestedPanel" Visible="false">
                <telerik:RadTabStrip runat="server" ID="RadTabStrip1" Visible="true" SelectedIndex="0" MultiPageID="Multipage1">
                    <Tabs>
                        <telerik:RadTab runat="server" Text="Tab1" PageViewID="PageView1">
                        </telerik:RadTab>
                        <telerik:RadTab runat="server" Text="Tab2" PageViewID="PageView2">
                        </telerik:RadTab>
                    </Tabs>
                </telerik:RadTabStrip>
                <telerik:RadMultiPage runat="server" ID="RadMultipage1" SelectedIndex="0" RenderSelectedPageOnly="false">
                    <telerik:RadPageView runat="server" ID="PageView1">
                       ....
                    </telerik:RadPageView>
                    <telerik:RadPageView runat="server" ID="PageView2">
                        <telerik:RadGrid ID="RadGrid2" AutoGenerateColumns="false" OnNeedDataSource="RadGrid2_NeedDataSource" runat="server">
                            <MasterTableView>
                                <Columns>
                                   ...
                                </Columns>
                            </MasterTableView>
                        </telerik:RadGrid>
                    </telerik:RadPageView>
                </telerik:RadMultiPage>
            </asp:Panel>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

c#:

 protected void RadGrid2_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    {
        RadGrid grid = (RadGrid)source;
        GridNestedViewItem nestedview = (GridNestedViewItem)grid.NamingContainer;
        string strtxt = ((GridDataItem)(nestedview.ParentItem)).GetDataKeyValue("ID").ToString();
        //...
    }

Thanks
