Hi All,

I want to define a radgrid in a template inside another radgrid so when I click on the modalpopbutton it fires up the second datagrid inside the panel;

<radG:RadGrid ID="rgDep" runat="server" AutoGenerateColumns="False" GridLines="None" Skin="WebBlue" AllowSorting="True" EnableAJAX="True">  
                        <MasterTableView> 
                            <Columns> 
                                  <radG:GridTemplateColumn UniqueName="TemplateColumn" HeaderText="Contact">  
                                      <ItemTemplate>                         
                                        <asp:LinkButton ID="btnShowDetails" runat="server" CausesValidation="false" Text='<%# Eval("Contact") %>'>  
                                        </asp:LinkButton>    
                                        <cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="pDepDetails" 
                                        OkControlID="btnOK" TargetControlID="btnShowDetails" BackgroundCssClass="modalBackground" DropShadow="true">  
                                        </cc1:ModalPopupExtender>                        
                                          <asp:Panel ID="pDepDetails" runat="server" BackColor="Beige" Font-Bold="True" style="display: none">  
                                              <asp:Label ID="lblDepID" runat="server" Text='<%# Eval("ContactID") %>'></asp:Label> 
                                              <br /> 
                                              <table> 
                                                  <tr>

                            </ExpandCollapseColumn> 
                        </MasterTableView> 
                    </radG:RadGrid> 
I was thinking to do inside the Itemdatabound of the first radgrid.;
Dim rgdepdetails As Telerik.WebControls.RadGrid = DirectCast(rgDep.Items(0).FindControl("rgDepDetails"), RadGrid)  
 
It throws an out of range error.

Any Ideas?

Thanks,
Shehab

Hi Shehab,

In ItemDataBound you can use e.Item instead Items collection.

All the best,

Thank you very much,

Now, I am getting Object reference not set to an instance of an Object;
    Protected Sub rgDep_ItemDataBound(ByVal sender As ObjectByVal e As Telerik.WebControls.GridItemEventArgs) Handles rgDep.ItemDataBound  
        Dim dataRow As DataRowView = CType(e.Item.DataItem, DataRowView)  
        Dim getDS As New DataSet  
        'Dim rgdepdetails As Telerik.WebControls.RadGrid = DirectCast(rgDep.Items(0).FindControl("rgDepDetails"), RadGrid)  
        If TypeOf e.Item Is GridDataItem Then 
            Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)  
            Dim rgdepdetails As RadGrid = CType(item.GetDataKeyValue("rgDepDetails"), RadGrid)  
            getDS = dataConn.PhoneSearchDep(txtSearch.Text)  
            rgdepdetails.DataSource = getDS  
        End If 
    End Sub 
and it wouldn't work if I add rgdepdetails to the keydatamember.

Thanks again.

Which line is it failing on? If it is th efirst line, I suggesst moving

Dim
 dataRow As DataRowView = CType(e.Item.DataItem, DataRowView)  

inside of your IF block. The dataitem does not exist for header rows, I beleieve.

Thanks for listening.

Hi Sean,

Thank you for the reply, it fails in the line;
rgdepdetails.DataSource = getDS 
where it assigns the datasource, I also tried to just do anything to the radgrid as set it to visible for example and it gives the same error.
