[Solved] RadGrid popupModal another radgrid

[Shehab]

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>

                        </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,

Hi Shehab,

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

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 Object, ByVal 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.
