5. other server controls
I. xmldatasource: function: enables XML data to be used for data binding controls. Display Hierarchical XML data; attributes: datafile, transformfile, and XPath;
1. Use the datafile attribute to specify the XML file to load XML data. 2. The control exposes the attributes of the XML element to fields that can be bound to Data. 3. Use XPath to filter data. You can also use the data attribute to embed XML data:<Asp: xmldatasource id = "mysource" datafile = "~ /App_data/bookstore. xml "XPath =" Bookstore/genre [@ name = 'fiction ']/book "runat =" server "> </ASP: xmldatasource>
<Asp: Treeview id = "treeview1" runat = "server" performanceid = "xmlperformance1"> <databindings> <asp: treenodebinding imageurl = "~ /Images/openbook.gif "textfield =" title "datamember =" book "/> <asp: treenodebinding imageurl = "~ /Images/notepad.gif "textfield =" name "datamember =" chapter "/> </databindings> </ASP: Treeview> </div> <asp: xmldatasource id = "xmlperformance1" runat = "server" XPath = "Bookstore/book"> <DATA> <bookstore> <book ISBN = "10-861003-324" Title =" tale of Two Cities "Price =" 19.99 "> <chapter num =" 1 "name =" Introduction "> abstract... </Chapter> <chapter num = "2" name = "body"> abstract... </Chapter> <chapter num = "3" name = "conclusion"> abstract... </Chapter> </book> <book ISBN = "1-861001-57-5" Title = "Pride and Prejudice" Price = "24.95"> <chapter num = "1 "Name =" Introduction "> abstract... </Chapter> <chapter num = "2" name = "body"> abstract... </Chapter> <chapter num = "3" name = "conclusion"> abstract... </Chapter> </book> </bookstore> </data> </ASP: xmldatasource>Ii. asp: XML: used to display XML documents or XSL conversion results,
| attribute | description | . Net |
|---|---|---|
| document | I do not agree to use it. Specifies the XML document that uses the system. xml. xmldocument object. | 1.0 |
| documentcontent | specify an XML string. | 1.0 |
| documentsource | specifies the path of the XML document displayed in the XML control. | 1.0 |
| runat | specifies that the control is a server control. Must be set to "server ". | 1.0 |
| transform | use the system. xml. XSL. Transform transform object to format the XML document. | 1.0 |
| transformargumentlist | contains the list of optional parameters that are passed to the style sheet and used in the extended style sheet language conversion (XSLT. | |
| transformsource | specifies the path of the XSL conversion file. | |
| xpathnavigator | the cursor model used to navigate and edit XML data associated with the XML control. |
by setting the transformsource attribute, you can specify an XSL conversion (XSLT) style table, which is formatted before the XML document is written to the output stream. These two attributes indicate different types of XSL conversion styles that can be used to format XML documents: Implementation subscription instance: Client:

1. Compile an XML text file called Web. sitemap, which defines the structural hierarchy of the entire page to be navigated;
2. AddSitemapdatasourceControl. This control automatically binds content in Web. sitemap;
3. SetSitemapdatasourceControls are bound to controls such as sitemappath, Treeview, and menu;
4. For details about the XML controls on the client, see DSO.5. other server-side controls:
1. template control:
