Examples

The following code example shows how to use a custom Web server control, derived from the WebControl class, that overrides the Render method. It uses the HtmlTextWriter class to write a <font> element. After it writes the opening tag of the element, it uses the InnerWriter property to write the string "<br> The time on the server:" and concatenates this string with the value of the DateTime.Now property.

   // Write the opening tag of a Font element.
   writer->WriteBeginTag( "font" );
   
   // Write a Color style attribute to the opening tag
   // of the Font element and set its value to red.
   writer->WriteAttribute( "color", "red" );
   
   // Write the closing character for the opening tag of
   // the Font element.
   writer->Write( '>' );
   
   // Use the InnerWriter property to create a TextWriter
   // object that will write the content found between
   // the opening and closing tags of the Font element.
   // Message is a string property of the control that
   // overrides the Render method.
   TextWriter^ innerTextWriter = writer->InnerWriter;
   innerTextWriter->Write( String::Concat( Message, "<br> The time on the server : ", System::DateTime::Now.ToLongTimeString() ) );
   
   // Write the closing tag of the Font element.
   writer->WriteEndTag( "font" );
}

    // Write the opening tag of a Font element.
    writer.WriteBeginTag("font");
    // Write a Color style attribute to the opening tag
    // of the Font element and set its value to red.
    writer.WriteAttribute("color", "red");
    // Write the closing character for the opening tag of
    // the Font element.
    writer.Write('>');

    // Use the InnerWriter property to create a TextWriter
    // object that will write the content found between
    // the opening and closing tags of the Font element.
    // Message is a string property of the control that 
    // overrides the Render method.
    TextWriter innerTextWriter = writer.InnerWriter;
    innerTextWriter.Write(Message + "<br> The time on the server :" + System.DateTime.Now.ToLongTimeString());

    // Write the closing tag of the Font element.
    writer.WriteEndTag("font");
}

        ' Write the opening tag of a Font element.
        writer.WriteBeginTag("font")
        ' Write a Color style attribute to the opening tag
        ' of the Font element and set its value to red.
        writer.WriteAttribute("color", "red")
        ' Write the closing character for the opening tag of
        ' the Font element.
        writer.Write(">")

        ' Use the InnerWriter property to create a TextWriter
        ' object that will write the content found between
        ' the opening and closing tags of the Font element.
        ' Message is a string property of the control that 
        ' overrides the Render method.
        Dim innerTextWriter As TextWriter = writer.InnerWriter
        innerTextWriter.Write((Message + "<br> The time on the server :" & _
           System.DateTime.Now.ToLongTimeString()))

        ' Write the closing tag of the Font element.
        writer.WriteEndTag("font")
    End Sub
End Class

Remarks

Inner markup content is the text found between the opening and closing tags of a markup language element.

If the InnerWriter property is set to a TextWriter object that is an instance of the HttpWriter class, this fact is noted and a separate reference is saved.
