Bind NestedViewTemplate from code behind

[Ajay]

Hi,
I have a RadGrid (parent) which is having another radGrid (child) inside the NestedViewTemplate.
I am providing the datasource of parent from code behind need datasource.

How can I bind the child radgrid from codebehind based upon the a column/datakey value of the parent grid?

In below code I have to fill the child grid with the  values sent by OAHSSQ column.



<telerik:RadGrid ID="radGridShippedOrders" runat="server" GridLines="None" AllowPaging="True"
            PageSize="10" AllowSorting="True" AutoGenerateColumns="false" ShowStatusBar="true"
            HorizontalAlign="NotSet" AllowMultiRowEdit="false" OnNeedDataSource="radGridShippedOrders_NeedDataSource" 
            OnItemDataBound="radGridShippedOrders_ItemDataBound" OnItemCommand="radGridShippedOrders_OnItemCommand"
            Width="800px" AllowMultiRowSelection="False" AllowFilteringByColumn="true" ShowGroupPanel="True">
            <PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="true"></PagerStyle>
            
            <ExportSettings ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true">
                 <Pdf PageTitle="Shipped Orders" />
            </ExportSettings>


            <MasterTableView GroupLoadMode="Client" CommandItemDisplay="Bottom" DataKeyNames="OAHSSQ" Name="MTVShippedOrders">
                <CommandItemTemplate>
                    <asp:Button ID="DownloadPDF" runat="server" CommandName="ExportToPdf" Text="Export" />
                </CommandItemTemplate>
                <CommandItemSettings ShowExportToExcelButton="true" />
                <Columns>
                    <telerik:GridBoundColumn UniqueName="OACONO" HeaderText="OACONO" DataField="OACONO">
                    </telerik:GridBoundColumn>                
                    <telerik:GridBoundColumn UniqueName="OAINNO" HeaderText="OAINNO" DataField="OAINNO">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn UniqueName="OAORNO" HeaderText="OAORNO" DataField="OAORNO">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn UniqueName="OAORGN" HeaderText="OAORGN" DataField="OAORGN">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn UniqueName="OAHSSQ" HeaderText="OAHSSQ" DataField="OAHSSQ">
                    </telerik:GridBoundColumn>
                                     
                </Columns>
                
                <NestedViewTemplate>
                
                    <telerik:RadGrid ID="radGridInvoiceHeader" runat="server" GridLines="None" AllowPaging="True"
                        PageSize="20" AllowSorting="True" AutoGenerateColumns="true" ShowStatusBar="true"
                        HorizontalAlign="NotSet" AllowMultiRowEdit="false" 
                        Width="100%" AllowMultiRowSelection="False" AllowFilteringByColumn="false">
                        <PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="true"></PagerStyle>
                    </telerik:RadGrid>

</NestedViewTemplate>
                                
                
            </MasterTableView>
             <ClientSettings AllowGroupExpandCollapse="True" ReorderColumnsOnClient="True" AllowDragToGroup="True"

Hello Ajay,

I have attached a sample project demonstrating how you can achieve the desired functionality. Have a look at it and let me know if it works for you.

I hope this helps.

Hi Pavlina,

Thanks for the solution, it worked perfectly.

Now I am facing a little problem while implementing this with multiple grids.
Actually I have 2 RadGrids inside the NestedViewTemplate, i.e. childGrid1 and childGrid2, I have implemented NeedDataSource for both of these.

Now there is a scenario, if the expand button is clicked first time in the parent grid, then the NeedDataSource of only the childGrid1 gets called and the childGrid2 displays no data as it's event was not called.
But for the next expand click commands NeedDataSource of both is called.

Can you please help me in this??

Thanks & Regards
Ajay
