Serves as the base class for all data source view classes, which define the capabilities of data source controls.
Assembly: System.Web (in System.Web.dll)
Initializes a new instance of theclass.
Gets a value indicating whether the DataSourceControl object supports retrieving the total number of data rows, instead of the data.object associated with the current
Gets a value indicating whether the DataSourceControl object supports a sorted view on the underlying data source.object associated with the current
Gets a list of event-handler delegates for the data source view.
Gets the name of the data source view.
Determines whether the specified command can be executed.
|Delete(IDictionary, IDictionary, DataSourceViewOperationCallback)|
Performs an asynchronous delete operation on the list of data that theobject represents.
Determines whether the specified object is equal to the current object.(Inherited from Object.)
|ExecuteCommand(String, IDictionary, IDictionary)|
Executes the specified command.
|ExecuteCommand(String, IDictionary, IDictionary, DataSourceViewOperationCallback)|
Executes the specified command.
Performs a delete operation on the list of data that theobject represents.
Performs an insert operation on the list of data that theobject represents.
Gets a list of data from the underlying data storage.
|ExecuteUpdate(IDictionary, IDictionary, IDictionary)|
Performs an update operation on the list of data that theobject represents.
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
Performs an asynchronous insert operation on the list of data that theobject represents.
Raises the DataSourceViewChanged event.
Gets a list of data asynchronously from the underlying data storage.
Returns a string that represents the current object.(Inherited from Object.)
|Update(IDictionary, IDictionary, IDictionary, DataSourceViewOperationCallback)|
Performs an asynchronous update operation on the list of data that theobject represents.
ASP.NET supports a data-binding architecture that enables Web server controls to bind to data in a consistent fashion. Web server controls that bind to data are referred to as data-bound controls, and the classes that facilitate that binding are called data source controls. Data source controls can represent any data source: a relational database, a file, a stream, a business object, and so on. Data source controls present data in a consistent way to data-bound controls, regardless of the source or format of the underlying data.
You use the data source controls that are provided with ASP.NET, including SqlDataSource, AccessDataSource, and XmlDataSource, to perform most Web development tasks. You use the base DataSourceControl and classes when you want to implement your own custom data source control.
You can think of a data source control as the combination of the IDataSource object and its associated lists of data, called data source views. Each list of data is represented by a object. The class is the base class for all data source views, or lists of data, associated with data source controls. Data source views define the capabilities of a data source control. Because the underlying data storage contains one or more lists of data, a data source control is always associated with one or more named data source views. The data source control uses the GetViewNames method to enumerate the data source views currently associated with the data source control and the GetView method to retrieve a specific data source view instance by name.
All ExecuteSelect method. All views optionally support a basic set of operations, including operations such as ExecuteInsert, ExecuteUpdate, and ExecuteDelete. A data-bound control can discover the capabilities of a data source control by retrieving an associated data source view using the GetView and GetViewNames methods, and by querying the view at design time or run time.objects support data retrieval from the underlying data source using the
Legacy Code Example
The following code example demonstrates how to extend the CsVDataSourceView class defines the capabilities of the CsvDataSource data source control and provides an implementation for data-bound controls to use data stored in comma-separated value (.csv) files. For more information on the CsvDataSource data source control, see the DataSourceControl class.class to create a strongly typed view class for a data source control. The Code snippet is not found. Confirm that the code snippet name 'Urtue.Samples.Alexkr.CsvDataSource_1' is correct.
