Creating the Class and SemanticItem Property

Start creating an example Application Speech Control by creating a new class that inherits from ApplicationControl in the Microsoft.Web.UI.SpeechControls.ApplicationControls namespace, and adding a constructor method.

using System;
using Systm.ComponentModel;
using System.Reflection;
using System.Web.UI;

using Microsoft.Speech.Web.UI;

namespace ColorChooserControl
{
    public class ColorChooser : ApplicationControl
    {
        public ColorChooser()
        {}
    }
}            

Next, declare a private string to store the name of the semantic item, and define a SemanticItem property. In order to make the SemanticItem property appear under the Speech category of the control's properties page in Visual Studio, precede the property definition with a line that designates the property as a member of the speech category.

#region Private Members

private string _semanticItem = string.Empty;

#endregion Private Members

#region Properties

[Category("Speech")]
public string SemanticItem
{
    get
    {
        return _semanticItem;
    }
    set
    {
        if(value == null)
        {
            _semanticItem = string.Empty;
        }
        _semanticItem = value;
    }
}
#endregion Properties
