Remarks

This property enables the automatic caching of assigned DataSource object. The default value is True which is a powerful and effective approach to reduce server's workload and dramatically increase server response time.

By utilizing the power of .NET caching feature, WebCombo.NET implements advanced datacaching mechanism to reduce server workloads. The scope of the cache is session. This enables a greater and more flexible control to the WebCombo object. The WebCombo control keeps track of each session's cache and will automatically remove the DataSource object from cache when it's no longer accessed.

If the DataSource object is a dynamic object -- means that it is changed or added in less than 5 minutes -- you may consider to set this property to False.

In order to take advantage of this property, you should always use IsDataCached to check whether the DataSource has already been cached before you assign a DataSource. See the example for details.

In some scenarios, you can assign a different DataSource directly from code with just assigning the DataSource property to new datasource. In this case, old cache will be automatically removed and new instance of cache will be created.
