What's New in ISDataSource.NET 1.0.1500.208?

• After updating the connection string from ObjectCreated server side event, the SelectCommand method still use the previous connection string specified in design-time.

ISDataSource.NET is a data source component for ASP.NET with the ability to support declarative multiple table views and hierarchical-relational dataset. Functions include advanced file server caching, cache configuration, load on demand and much more. ISDataSource.NET is designed to resolve limitations in the existing data source control that shipped with ASP.NET. ISDataSource.NET also includes an intuitive, time-saving Wizard.

ISDataSource.NET Main features:

• Support for multiple tables
• Centralized settings for all tables included in the data source: Since ISDataSource supports multiple table definition, with only using one control you can organize which tables will be used in the page and how the tables access, retrieve, and modify the data. With all tables are collected in one control, you can also set a configuration settings from ISDataSource control level or ISDataSourceTable level. Therefore it is easier to manage all the configuration settings for all DataSource that will be used in a page.
• Enhanced designer with step-by-step wizard: ISDataSource.NET package also comes with a wizard designer. The designer is adapted from ObjectDataSource wizard designer with some additional features and implementation that supports the overall architecture. ISDataSource.NET designer is divided into three sections that are Schema definition, Method / Table definition, and Parameter definition. One of the valuable features in ISDataSource.NET architecture is the ability to generate / predefined all tables' definition based on the given schema (DataSet schema). Thus with only three clicks you can have a structured data source completes with all the table definition on how to process the data.
• Enhanced caching mechanism: The enhanced caching mechanism provided in ISDataSource enables you to use cache data instead of retrieving it from the business object that associated with enhanced settings such as CacheStorage (You can choose between Page Cache, Session, or FileServer), CacheScope (Global/Per User), CachePriority, StoreCachePerPage ( which allows you to decide whether to distinguish the data between pages), CacheDuration & CacheExpirationPolicy, and Use cache on first load which provides the ability to determine whether ISDataSource.NET will use the cache data on first load or always look for actual data from database.
• Integration with .NET data-bound controls: You can select which table to be bounded by utilizing the data member property of .NET data bound controls. If you use Typed DataSet as table definition, by default the .NET data bound controls will generate the column based on data member that you select.
• Integration with Intersoftpt data-bound controls: Able to work with Intersoftpt components and strengthen each Intersoftpt data-bound control abilities such as Hierarchical Data Retrieval. Load on demand is one of important key features in WebGrid.NET. ISDataSource is also designed to support all load on demand scenarios in WebGrid.NET and also in WebCombo.NET. Three types of load on demand that supported by ISDataSource are Virtual Page load on demand (Custom VirtualLoad), Hierarchical load on demand, and Self-Reference load on demand.
• Strong support for custom object: Instead of specifying several parameters that are passed to the Update, Insert and Delete methods, we can create one object that aggregates several data fields value and passed this one object instead of several parameters. In order to do that you need to specify the Type of the object in DataObjectTypeName property. The type that is specified by DataObjectTypeName property must have a default constructor that has no parameters and setable properties that have the exact name as the parameter name that are passed by data-bound controls. For Insert / Update / Delete operations, the ISDataSource expect an object of type "DataObject.MyData" as parameter. This object will act as a BusinessObject to hold information from data-bound controls to ISDataSource control.
• Strong support for generic collection: Based on the capabilities of the business object that the ISDataSource control works with, you can perform data operations such as updates, inserts, and deletes. In order to perform these data operations, you need to set the appropriate method name and any associated parameters for the operation that you want to perform.
