Examples

The following code example demonstrates how to use a custom class named TextSample, derived from the WebControl class, that uses the EnterStyle method to apply a ForeColor style to a string of text.

The EnterStyle method renders the HTML <span style="color:Navy;">. The ExitStyle method call closes the <span> element after the text has been rendered.

            writer.ExitStyle(textStyle)

            ' Use the WriteBreak method twice to render
            ' an empty line between the lines of rendered text.
            writer.WriteBreak()
            writer.WriteBreak()

            ' Render the Text property without the style.
            writer.WriteLine("The Text property unstyled: ")
            writer.Write(Text)
        End Sub
    End Class
End Namespace

Remarks

The ExitStyle overload of the ExitStyle(Style) method renders the closing tag of a <span> element after the closing tag of the control, closing the element opened by the corresponding EnterStyle call.

The ExitStyle and EnterStyle methods allow a device adapter or control to create markup that begins and ends a block by using the character formatting of the specified style. Use the same value for style in the EnterStyle method that you use in the corresponding ExitStyle method.
