Grid inside a grid

[Smiely]

Hi,
I am following http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx this example.
On one of the panels, I have a grid. What I would like to do is, do not display grid if there is no data. Display a single line message.
How can I do that ???

Please help,

Thanks

Hello Smiley,

You can place a Label/Literal(with Text as display message)  inside RadPageView (which contail Radgrid) and initially make its visibility as 'false'. In PreRender event of Grid check whether the grid is empty or not and display the message accordingly. Sample code is given below.

ASPX:

<telerik:RadMultiPage runat="server" ID="Multipage1" SelectedIndex="0" RenderSelectedPageOnly="false">
     <telerik:RadPageView runat="server" ID="PageView1">
         <asp:Literal ID="Literal1" runat="server" Text="No record to Display" Visible="false"></asp:Literal>
             <telerik:RadGrid runat="server" ID="OrdersGrid" .  .  .>
             </telerik:RadGrid>
     </telerik:RadPageView>
</telerik:RadMultiPage>

C#:

protected void OrdersGrid_PreRender(object sender, EventArgs e)
    {
        RadGrid OrdersGrid = (RadGrid)sender;
        RadPageView pageview = (RadPageView)OrdersGrid.Parent;
        Literal Literal1 = (Literal)pageview.FindControl("Literal1");
        if (OrdersGrid.Items.Count == 0)//checking whether grid is empty
        {
            Literal1.Visible = true;
            OrdersGrid.Visible = false;
        }
    }

Thanks,
Princy.

 Thanks for replying Princy.  That's a smart solution and it's working also! But now I figured out that I don't have a dedicated Datasource on that grid. It's displaying bunch of values from it's parents datasource.

<telerik:RadPageView runat="server" ID="PageView2" width="500px">

  <legend style="padding: 5px;"><b>Detail Assignment info for TaskID:   <%#Eval("TaskID") %></b>
   </legend>
    <asp:Literal ID = "Literal1" runat="server" Text=" NOT ASSIGNED " Visible="false"></asp:Literal>
    <telerik:RadGrid ID="assignmentRadGrid" runat="server" DataSourceID="nestedObjectDataSource" Skin="WebBlue" Visible="true" onprerender="assignmentRadGrid_PreRender">
     <MasterTableView ShowHeader="true" DataKeyNames="TaskID" AutoGenerateColumns="False">
      <ParentTableRelation><telerik:GridRelationFields  DetailKeyField="TaskID"/></ParentTableRelation>
       <Columns>
       <telerik:GridBoundColumn   HeaderText="Assigned To" DataField="AssignedToName" UniqueName="AssignedTo"></telerik:GridBoundColumn>
         <telerik:GridBoundColumn  HeaderText="Assigned From" DataField="AssignedByName" UniqueName="AssignedBy"></telerik:GridBoundColumn>
           <telerik:GridBoundColumn  HeaderText="Assigned On" DataField="AssignedOn" UniqueName="AssignedOn"></telerik:GridBoundColumn>
             </Columns>
                              </MasterTableView>
                             </telerik:RadGrid>
                             </div>
                           </telerik:RadPageView>

That "nestedObjectDataSource" is also it's parents grid DataSource. How do I find out "There is no AssignedToName, AssignedByName, AssignedOn for a specific TaskID"

Please help,

Thanks
