DataSourceControl.GetViewNames Method

Gets a collection of names, representing the list of DataSourceView objects associated with the DataSourceControl control.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

abstract GetViewNames : unit -> ICollection  
override GetViewNames : unit -> ICollection

Return Value

Type: System.Collections.ICollection
An ICollection that contains the names of the DataSourceView objects associated with the DataSourceControl.

The ICollection collection of names is the allowable set of values that can be passed to the GetView method.

The ListSourceHelper class, which is used for the DataSourceControl class's IListSource implementation, checks the GetViewNames method for both the IListSource.ContainsListCollection and IListSource.GetList calls to determine whether the data source control is associated with one or more data source views. If GetViewNames returns a null reference (Nothing in Visual Basic), which is the default implementation of the method, IListSource.ContainsListCollection returns false and IListSource.GetList returns a null reference (Nothing in Visual Basic).

NoteNote

The DataSourceControl class's default implementation returns a null reference (Nothing in Visual Basic). If you extend the DataSourceControl class, override the GetViewNames method to return a collection of view names.

The following code example demonstrates how a class that extends the DataSourceControl class can override the default implementation, which returns a null reference (Nothing in Visual Basic), to provide a collection of view names. The CsvDataSource class only supports one view; therefore, a collection of one element with the default view name is returned. This code example is part of a larger example provided for the DataSourceControl class.

No code example is currently available or this language may not be supported.
