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

ICollection GetViewNames()

Return Value

Type: System.Collections.ICollection

An ICollection that contains the names of the views associated with the IDataSource.

Data source control classes can support one or more named views on their underlying data. The GetViewNames method returns a collection of view names currently associated with the data source control instance. Callers can iterate through the collection of view names and retrieve individual DataSourceView objects with the GetView method.

Data source control classes that implement the IDataSource interface implement the GetViewNames method to return a collection of names that represents all the data source view objects currently associated with the data source control class.

The following code example demonstrates how a data source control that implements the IDataSource interface implements the GetViewNames method, returning an ICollection collection of names. Because the data source supports only one view, the method returns a collection of one element using the default name for the view. This code example is part of a larger example provided for the DataSourceControl class.

    // The ListSourceHelper class calls GetList, which
    // calls the DataSourceControl.GetViewNames method.
    // Override the original implementation to return
    // a collection of one element, the default view name.
    protected override ICollection GetViewNames() {
        ArrayList al = new ArrayList(1);
        al.Add(CsvDataSourceView.DefaultViewName);
        return al as ICollection;
    }
}
