Hi there,

I am trying to exportToPDF in a radgrid.   It seems to work fine except for a gridtemplatecolumn i have which contains another radgrid.

So basically, each row has a column which contains a grid containing a list of strings (they are validation msg's).  

I have found a few threads telling me to enable the viewstate for the grid, and also, to ExportOnlyData="false", which has no affect.

Everything else seems to work fine, except the exporting.

thanks in advance!

Neil

below is the code:
<telerik:RadGrid id="rgdListLicences"   runat="server" Width="100%"  OnNeedDataSource="rgdListLicences_NeedDataSource"  GridLines="None" Skin="eLicensing_paging"  EnableEmbeddedSkins="false" EnableViewState="true">
                     <ExportSettings IgnorePaging="true" OpenInNewWindow="true" ExportOnlyData="false"   >
                        <Pdf PageHeight="210mm" AllowPrinting="true"   PageWidth="297mm" PageTitle="Print Validations" DefaultFontFamily="Arial Unicode MS"
                        PageBottomMargin="20mm" PageTopMargin="20mm"  PageLeftMargin="20mm" PageRightMargin="20mm" />
                     </ExportSettings>
                     <MasterTableView RetrieveAllDataFields="false" CommandItemDisplay="Top" AutoGenerateColumns="false"  >
                        <CommandItemTemplate>
                                <telerik:radbutton ID="DownloadPDF" AutoPostBack="true" CssClass="pdfButton" runat="server"  Width="10%" Text="Print Validations" CommandName="ExportToPdf"/>
       
                        </CommandItemTemplate>
                        <Columns>
                            <telerik:GridBoundColumn DataField="clientRef" DataFormatString="{0:dd/MM/yy}" HeaderText="Client Ref"><ItemStyle Width="12%" VerticalAlign="Top" />
                            </telerik:GridBoundColumn>
                            <telerik:GridBoundColumn DataField="ServiceName" HeaderText="Service Name"><ItemStyle Width="28%" VerticalAlign="Top" />
                            </telerik:GridBoundColumn>
                            <telerik:GridBoundColumn DataField="commencementDate" DataFormatString="{0:dd/MM/yy}" HeaderText="Start Date"><ItemStyle Width="12%"  VerticalAlign="Top" />
                            </telerik:GridBoundColumn>
                            <telerik:GridTemplateColumn UniqueName="validations" HeaderText="Validations" SortExpression="CompanyName"  >
                                <ItemTemplate>
                                    <telerik:radgrid ID="rgdValidations"  OnNeedDataSource="rgdValidations_NeedDataSource" BorderStyle="None" ShowHeader="false" runat="server"  EnableViewState="true" >
                                        <MasterTableView>
                                            <ItemStyle Font-Size="Smaller" />
                                            <AlternatingItemStyle Font-Size="Smaller"/>
                                        </MasterTableView>
                                    </telerik:radgrid>
                                </ItemTemplate>
                            </telerik:GridTemplateColumn>
                        </Columns>
                    </MasterTableView>
                </telerik:RadGrid>

Protected Sub rgdValidations_NeedDataSource(ByVal sender As Object, ByVal e As GridNeedDataSourceEventArgs)
 
    Dim RadGrid2 As RadGrid = CType(sender, RadGrid)
    Dim item As GridDataItem = RadGrid2.NamingContainer
    Dim validations As List(Of String) = CType(item.DataItem, LicencesLicence).validations
 
    RadGrid2.DataSource = validations
End Sub

Hello Neil,

Exporting nested RadGrids is tricky and may not work as you expected. I would recommend that you disable the IgnorePaging property.
Also you can examine the following code-library project.
