Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[BrowsableAttribute(false)]
public XslTransform Transform { get; set; }
<asp:Xml Transform="XslTransform" />

Property Value

Type: System.Xml.Xsl.XslTransform
The System.Xml.Xsl.XslTransform that formats the XML document before it is written to the output stream.

When using the Xml control to display an XML document, you can optionally specify an Extensible Stylesheet Language Transformation (XSLT) style sheet that formats the XML document, before it is written to the output stream in one of two ways. You can format the XML document with either a System.Xml.Xsl.XslTransform object or an XSL Transformation style sheet file. If no XSL Transform document is specified, the XML document is displayed using the default format. The Transform property is used to specify a System.Xml.Xsl.XslTransform object (representing an XSL Transform document) used to format the XML document before it is written to the output stream.

NoteNote

Using a System.Xml.Xsl.XslTransform object requires Full Trust permissions.

The following example demonstrates how to create XmlDocument and 
XslTransform objects from the sample XML and XSL Transform files. 
The objects are then used by the Xml control to display the XML 
document. Make sure the sample XML file is called People.xml and 
the sample XSL Transform file is called Peopletable.xsl.
