ExportToPDF Problem, with GridTemplateColumn

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

ComboBox AutomaticLoadOnDemand - multiple postbacks and detection of them

Hi,

I am using the radcombobox with automatica load on demand:

<telerik:RadComboBox ID="cboSKU" runat="server"

DataTextField="STCode" DataValueField="STCode" MarkFirstMatch="true" ShowToggleImage="false"

EnableAutomaticLoadOnDemand="true" ShowMoreResultsBox="true" ItemsPerRequest="30"

AutoPostBack="true" onselectedindexchanged="cboSKU_SelectedIndexChanged"

>

this works as expected. This combo box is on an aspx page using a master page. On the master page I'm logging events - however I do not want to capture ajax postbacks. (I do want to capture non ajax postbacks, but not postbacks from, for example, the combo box repopulating values as you type)

i have tried:

if (RadAjaxManager1.IsAjaxRequest == false)

{

AddLogEntry();

}

and

if (ScriptManager.GetCurrent(Page).IsInAsyncPostBack == false)

{

AddLogEntry();

}

with no success.

Any advice would be appreciated.

Thank you,
Ryan

Editor - Export to Pdf Table widths in % does not render as expected

Hi All,

My user is having Html content having width set in % for TD. But when it is exported to pdf, it does not render it as per % set. It defaults to Total table width / no of TD.

<table style="width:100%;">
<tr>
   <td style="width:10%;">No</td>
   <td style="width:70%;">Full Name</td>
   <td style="width:20%;">Telephone</td>
</tr>
</table>

It displays <table> with all TDs having equal width i.e. 33% appx.

Thanks in advance for all replies.
