ASPxNavBar - How to bind a control to an XML file by using an XSLT file

When the ASPxNavBar is bound to XmlDataSource, the latter should suit the following structure:

[XML]
<Root><GroupText="Reports"><ItemText=" ... "NavigateUrl="..."ImageUrl="..."/></Group></Root>

In this case, XmlDataSource can retrieve and synchronize the Text, NavigateUrl and ImageUrl XML attributes with ASPxNavBar properties. However, in real applications, data seldom suits this structure. Most often, an XML schema contains several sub- nodes that describe some element. For instance:

[XML]
<Menus><Menutext="abc1"><ProductID>193</ProductID><ProductName>090 - Introduction</ProductName><PTName>Video</PTName></Menu></Menus>

XmlDataSource cannot parse such a schema. However, XmlDataSource allows specifying an XSLT file where you can define a transformation that will be applied to the specified DataFile. In this case, it is necessary to utilize the GroupContentTemplate. For example:

[XML]
<xsl:stylesheetversion="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:templatematch="/"><Menus><xsl:for-eachselect="//Menus/*"><MenuText="{ProductName}"ProductID="{ProductID}"></Menu></xsl:for-each></Menus></xsl:template></xsl:stylesheet><GroupContentTemplate>
   ProductID:<asp:LabelID="Label1"runat="server"Text='<%# DataBinder.Eval(Container.Group.DataItem, "ProductID") %>'></asp:Label></GroupContentTemplate>
