Description

In some scenarios, you may need to add the same extension twice. For example, for XLSX once with a native header and once without.

Suggested Workarounds

You may register the second extension with a different name, i.e. XLSX1 as a custom extension, and set its type to the built-in type from our code that renders in the corresponding format, for example, XLSX. The following configuration generates two XLSX rendering types, one with UseNativePageHeader set to true, and the other to false:

<Telerik.Reporting>
	<extensions>
		<render>
			<extension name="XLSX" description="abc">
				<parameters>
					<parameter name="UseNativePageHeader" value="true" />
				</parameters>
			</extension>
			<extension name="XLSX1" type="Telerik.Reporting.OpenXmlRendering.Spreadsheet.SpreadsheetReport, Telerik.Reporting.OpenXmlRendering" description="xlsx1">
				<parameters>
					<parameter name="UseNativePageHeader" value="false" />
				</parameters>
			</extension>
		</render>
	</extensions>
</Telerik.Reporting>

Here is how you may register some alternative rendering extension with the built-in renderers in Telerik Reporting:

<extension name="XLSX1" type="Telerik.Reporting.OpenXmlRendering.Spreadsheet.SpreadsheetReport, Telerik.Reporting.OpenXmlRendering" description="xlsx1" />
<extension name="DOCX1" type="Telerik.Reporting.OpenXmlRendering.Wordprocessing.WordprocessingReport, Telerik.Reporting.OpenXmlRendering" description="docx1" />
<extension name="PPTX1" type="Telerik.Reporting.OpenXmlRendering.Presentation.PresentationReport, Telerik.Reporting.OpenXmlRendering" description="pptx1" />
<extension name="XLS1" type="Telerik.Reporting.ExcelRendering.Excel97.ExcelReport, Telerik.Reporting" description="xls1" />
<extension name="CSV1" type="Telerik.Reporting.CsvRendering.CsvRenderingExtension, Telerik.Reporting" description="csv1" />
<extension name="PDF1" type="Telerik.Reporting.ImageRendering.PdfReport, Telerik.Reporting" description="pdf1" />
