  I am using this code, for nested table (Details tables). my sample code for your reference.

    <telerik:RadGrid ID="rgFeedback" runat="server" Width="100%" ShowStatusBar="True"
        AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True" PageSize="5"
        Skin="Vista" GridLines="None" OnDetailTableDataBind="rgFeedback_DetailTableDataBind"
        OnItemCommand="rgFeedback_ItemCommand">
        <MasterTableView DataKeyNames="FeedbackQuestionGroupId">
            <DetailTables>
                <telerik:GridTableView ShowHeader="false" DataKeyNames="FeedBackQuestionId" Name="FeedBackQuestion"
                    Width="100%">

                                <asp:Label ID="lbl_Question" Width="50%" Text='<%# Eval("FeedbackQuestionName") %>'
                                    runat="server" />
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
                        <telerik:GridTemplateColumn UniqueName="AAA2">

                <telerik:GridButtonColumn ButtonType="PushButton" UniqueName="SaveQuestionGroup"
                    CommandName="SaveQuestionGroup" ConfirmTitle="CMS asking..." ConfirmText="Save question group details"
                    Text="Save Question Group">
                </telerik:GridButtonColumn>
            </Columns>
            <NoRecordsTemplate>
                <div style="width: 100%; height: 15px; color: Red; text-align: left;">
                    No Records Found.

Hello Selvan,

                     I guess you want to access the controls on clicking the ButttonColumn control. If so the following code will help you to access the Label and Rating control from the corresponding row in the "rgFeedback_ItemCommand" event. 

C#.

protected void rgFeedback_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
   {
       if (e.CommandName == "SaveQuestionGroup")
       {
           Label lblParent = (Label)e.Item.FindControl("lblQuestionGroupName1");
           lblParent.Text = "New text";
           GridTableView tableView = (GridTableView)(e.Item as GridDataItem).ChildItem.NestedTableViews[0];
           foreach (GridDataItem item in tableView.Items)
           {
               RadRating rrRatings = (RadRating)item.FindControl("rrRatings");
               int i =Convert.ToInt16( rrRatings.Value);
           }
       }
   }

Shinu.
