ListSourceHelper.ContainsListCollection Method

Indicates whether the specified data source control contains a collection of data source view objects.

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

public static bool ContainsListCollection(
	IDataSource dataSource
)

Parameters

dataSource
Type: System.Web.UI.IDataSource

An IDataSource that specifies the data source control to test for associated data source view objects.

Return Value

Type: System.Boolean
true if the data source control contains a collection of data source view objects; otherwise, false.

Use this method in an implementation of the ContainsListCollection property, passing a reference to a data source control.

The following code example demonstrates the design pattern for a data source class that implements the IListSource methods. The ContainsListCollection property calls the static ContainsListCollection method.

#region Implementation of IListSource

bool IListSource.ContainsListCollection {
    get {
        return ListSourceHelper.ContainsListCollection(this);
    }
}

IList IListSource.GetList() {
    return ListSourceHelper.GetList(this);
}
