1. HTML template
   HTML Template is a regular text file with HTML elements: tables, images, controls, etc.



2. XSL template
   XSL Template is more flexible than HTML template, because it includes XSL elements. XSL Template allows comparing/modifying data without a loss in performance. For example, under conditional formatting you must first analyze item's data and then apply the formatting.
   
   XSL Template must include two key elements: the <xsl:call-template name="Main" /> and the <xsl:template name="Main">. Sample code of XSL Template:
   
   

   <?xml version="1.0" encoding="UTF-8" ?>
   <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
       <xsl:output method="xml" version="1.0" indent="no" omit-xml-declaration="yes" />
   
       <xsl:template match="/">
           <xsl:call-template name="Main" />
       </xsl:template>
   
       <xsl:template name="Main">
           ...
       </xsl:template>
   
   </xsl:stylesheet>
   




3. ASCX template (User Control)
   ASCX Template is most flexible because it allows developer to format an item by using the preferred programming language (C# or VB.NET). ASCX Template can include the field TreeViewElement which must be declared as public. You can use this field to have access to the item in Template's code.
   
   
   [C#]

   public APNSoft.WebControls.TreeViewElement TreeViewElement = null;
               

   [VB.NET]

   Public TreeViewElement As APNSoft.WebControls.TreeViewElement = Nothing
               

• $ComponentID$ - displays the unique identifier of the component.
• $ItemID$ - displays the unique identifier of the item.
• $Title$ - displays the text (caption) of the item.

<item title="HTML" Template="~/Templates/Template.html" />
<item title="XSL" Template="~/Templates/Template.xsl" />
<item title="ASCX" Template="~/Templates/Template.ascx" />
