CheckBoxList.CreateControlStyle Method ()

 

This API supports the product infrastructure and is not intended to be used directly from your code.

Creates a style object that is used internally by the CheckBoxList control to implement all style related properties.

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

protected override Style CreateControlStyle()

Return Value

Type: System.Web.UI.WebControls.Style

A Style that contains the style properties of the control.

The CreateControlStyle method is used primarily by control developers in custom controls that derive from the CheckBoxList class.

The following code example demonstrates how to override the CreateControlStyle method in a custom server control so that it always returns a new instance of the TableStyle class for the CheckBoxList control.
