ASP.NET AJAX & ExtJS 4 Grid (4)

Read Previous Example First!

In this example, we'll improve our ExtJS 4 model to include an "association" that it will read from XML produced by AJAX call to ASP.NET. Most common association is one to many, for example: your Client can place multiple Orders. An ExtJS 4 data store and model can accommodate this.

The new XML data packet will look like this; notice hiddenAttributes:

<?xml version="1.0" encoding="utf-8"?>
<matches>
	<match>
		<id>0</id>
		<name>Number 0</name>
		<hiddenAttributes>
			<attr>
				<name>hidden1</name>
				<value>val1</value>
			</attr>
			<attr>
				<name>hidden2</name>
				<value>val2</value>
			</attr>
		</hiddenAttributes>
	</match>
	<match><id>1</id><name>Number 1</name></match>
	...
</matches>
