- * @class Ext.grid.PropertyRecord
- * A specific {@link Ext.data.Record} type that represents a name/value pair and is made to work with the
- * {@link Ext.grid.PropertyGrid}. Typically, PropertyRecords do not need to be created directly as they can be
- * created implicitly by simply using the appropriate data configs either via the {@link Ext.grid.PropertyGrid#source}
- * config property or by calling {@link Ext.grid.PropertyGrid#setSource}. However, if the need arises, these records
- * can also be created explicitly as shwon below. Example usage:
- * <pre><code>
- var rec = new Ext.grid.PropertyRecord({
- name: 'Birthday',
- value: new Date(Date.parse('05/26/1972'))
- });
- // Add record to an already populated grid
- grid.store.addSorted(rec);
- </code></pre>
- * @constructor
- * @param {Object} config A data object in the format: {name: [name], value: [value]}. The specified value's type
- * will be read automatically by the grid to determine the type of editor to use when displaying it.
