Hi Narendra,

The ClientExportManager is based on the Kendo Drawing API library and both do support inches and mm values as explained in Configuration.

Regardless of the selected metric type the rendered content in the PDF will be a bit bigger. You can test for example this demo - Export Whole Pages and see the differences in this screenshot.

Since the exported text and shapes will be always bigger in the PDF, you may want to use the .k-pdf-export class which is applied only to the exported content and apply a bit smaller fonts than the ones applied in the HTML/aspx page. For more details check this page: Change the Exported Content before Export.

The ClientExportManager uses typographic points unit. The size of the content in pixels matches the size of the output in points (1 pixel = 1/72 inch). This is explained in the PDF Options article -> paperSize setting.
This article could be also helpful Dimensions and CSS Units.

Hi,

Please find an example of how to export two divs placed one by one with a chart and a grid inside them in two subsequent pdf pages:

ASPX:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<telerik:RadButton RenderMode="Lightweight" ID="RadButton1" runat="server" OnClientClicked="exportAllPanelItems" Text="Export Items" AutoPostBack="false" UseSubmitBehavior="false"></telerik:RadButton>

var cem = $find("<%=RadClientExportManager1.ClientID%>");

cem.exportPDF($telerik.$(".panel-container"));

}
