The new AJAX 4 Version offers a new client side template engine. With this new engine it is possible to define data templates within HTML. The template engine offers three different ways to bind data. A good whitepaper and overview about all the new functionalities is available here.

I implemented a small example to demonstrate different technologies and the cooperation between the different tools. My example is using:

• Entity Framework / Entity Data Model
• ADO.NET Data Service
• AJAX 4 Preview
• JQuery + JQuery UI

I used the Northwind database and the employee data for my example.

The below pictures explain the different parts and technologies.

Application Architecture overview:

The example application contains a list of employee data. I used the client side data template from the AJAX 4 Preview Version to render the data table:

<table class="sys-template" border="0" width="100%" id="dataview" sys:attach="dv" dv:sys-key="master" dv:selecteditemclass="itemSelected" dv:oncommand="dataview_oncommand(sender,args)">
<tr class="sys-item-template" sys:command="Select">
  <td sys:command="Select">{{ FirstName }}</td>
  <td>{{ LastName }}</td>
  <td>{{ Address }}</td>
  <td>{{ City }}</td>
  <td>{{ Region }}</td>
</tr>
</table>

The complete example application is using pure JavaScript, there is no need to have either a *.aspx or codebehind *.aspx.cs file.
