        public string Name
        {
            get { return _Name; }
            set { _Name = value; }

                               //Another way of adding controls to Properties pane

       [System.Web.UI.WebControls.WebParts.WebBrowsable(true),
        System.Web.UI.WebControls.WebParts.WebDisplayName("Enter Comment"),
        System.Web.UI.WebControls.WebParts.WebDescription("Comment"),
        System.Web.UI.WebControls.WebParts.Personalizable(
        System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared),
        System.ComponentModel.Category("Custom Properties"),
        System.ComponentModel.DefaultValue("")]
        public string Cmd
        {
            get { return _cmd; }
            set { _cmd = value; }
        }

       WebDisplayName("Set Width"),WebDescription("Set width"),Category("Custom Properties")]

 /*This actually represents the Field  - Textbox (Integer)*/

        public int setWidth
        {
            get{return _Width;} 
            set{_Width = value;}
        }
       
        protected override void CreateChildControls()
        {
            lblResult = new Label();
            btnClick = new Button();
            btnClick.Text = "Click";
            btnClick.Click += new EventHandler(btnClick_Click);
            this.Controls.Add(lblResult);
            this.Controls.Add(btnClick);
        }

        protected void btnClick_Click(object sender, EventArgs e)
        {
           lblResult.Text = "Welcome" + " " + _Name.ToString() + "<br /> Your Valuable Comment: " + Cmd.ToString()+"<br/>You have set the width as :"+setWidth+"<br/><br/>";
            if(setWidth!=0)
            btnClick.Width = setWidth;
            else
            btnClick.Width = 500;
